Default First online video: Some questions.

I have a Sony DCR-SR72 25 Megapixel video camera with 60 Gb harddisk and up to 41 hours recording. In addition I installed the Sony Picture Motion Browser.



Here Index of /temp are the directory of the first two video clips:
  1. http://www.dinmediaside.no/temp/20080102124316.mpg 7.7 Mb
  2. http://www.dinmediaside.no/temp/20080913120424.mpg 671 Mb
They are stored on a server in the USA.

It took 5 hours and 10 minutes to upload the biggest clip.



Questions:
  1. Can you see / stream the clips online without downloading them?
  2. Which software program are you using to view the clips and how are the quality?
In addition:
  1. Do you know of a better (faster) way to upload clips to the server, eg, compressing and unpacking it on the server?
  2. Do you know of a cheap hoster for video clips. The largest clip is only 12 minutes long, so I may need capacity. I know there are a lot of hosters offering unlimited hosting space, but that is in my opinion in theory and not in practice for storing movies.
Note this is my first clips. The clips are of my son and I am commenting the cilps in Norwegian. I know that you shall be careful when launching your movie clips online. Any opinion on that too?

You probably want to look for a host that supports some sort of streaming server or FFmpeg hosting (like youtube) is getting pretty popular and works very well.

There are lots of scripts that can help you do this but not all hosts support FFmpeg. One script I can think of that works well for this is PHPMotion.

Keep in mind there is no such thing as unlimited space, it is a marketing trick. You need to read the fine print with such hosts. When was the last time you saw an "unlimited" hard drive down at your local computer store? There is always some limit, and unlimited disk is a deception that should be avoided.

As for you upload, much of that has to do with your ISP. Most cap upload at 128k or 256k which is just 2x or 4x faster than dial-up, respectively.

Mine caps at 384k even though they claim I have a 7 Meg connection the majority of that pipe it is used for download.

A product that's available for a fair price that I use is Easyflv, great for turning video files in flv files that you can then stream. They include the applets et all, pretty much turnkey operation. I have yet to have a complaint or a problem. Just download, convert and post to your website, 30 minutes

The Link
Add video to any website with our set of Streaming Video Software and Web Video Players

the whole thing runs $37 I am not an affiliate, just a user

Yes unlimited bandwidth is also a marketing myth.

If you think what kind of traffic can slam a server for a simple script then you can imagine what happens with video....

I also think you need to realize that today few people will want to sit through 10 mins of video unless they are hardcore fans of the offering.

We live in short attention span theater now.. so keep the vids short sweet and to the point!

KGUN - the first thing is the need for a better editing package. I would recommend using something like Camtasia Studio, which can seriously reduce the file size of a video. A 12 minute video should never be that size.

Camtasia can spit the video out into numerous different file types and players, including a flash player which can be customized to your needs. I would start there, a great product for a small investment.

It also allows you to do other things such as do screen captures as video, so you could train on a software package or something along those lines. That software, plus a decent mic can provide good production along with the camera you have now.

No need to pay any money to convert something to flash video (.flv). Plenty of great free open source options out there.

Pazera does this just fine, for free. I've used it on a bunch of videos, has converted mpg, avi, pretty much everything I can throw at it. It's basically a nice front-end to ffmpeg, mentioned earlier, which is an open source media converter.

Free Video to Flash Converter 1.0 - Convert video files to Flash Video (FLV, SWF), AVI to FLV, AVI to YouTube FLV converter - Jacek Pazera

You can play with the settings in pazera like frames per second and encoding bitrate, even video size, to help you balance size vs. quality. I get huge files too coming off of Sony Vegas, but Pazera can reduce it down with no problems. And it runs on Windows.

My son has Vista Ultimate. He had no problems with the small clip. It downloaded and opened in Windows Mediaplayer. He has not responded to the larger clip, since it was uploaded later.

  1. Why?
  2. Is it easy and is the quality the same after transformation?

  1. Are you sure that Soney movie files can be transfromed and edited with that program?
  2. Again, what about quality after transformation?
Note my answer in this http://www.webproworld.com/breakroom...tml#post386875 thread. Movie editing is not the problem. The problem is online streaming, packing and unpacking on the server, quality, hosting (future needs - I will prefer to use my own site and not rely on third parties like Youtube etc), functionality in public software like Windows MediaPlayer and other media players.


The software that follows with the camera, has
  1. Good presentation functionality. Separate clips can be showed continuously.
  2. Movie editing.
  3. DVD burning etc.
  4. Online updates like Windows live update.
The drawback is that the program is proprietary as far as I know. My conclusion so far:
  1. The files have to be downloaded before playing.
  2. There are problems viewing the clips in Windows Media Player. Note that the smallest clip is very short (7 seconds) and suddenly cuts off. I added it for those that would not try the larger clip.

KGUN, well, you posted MPG videos, so I figured that was what you were working with. The quality I've seen is very good out of Camtasia Studio, and the nice thing is that it isn't just a file converter. It also offers you much more in the avenue of capturing videos and such. Nice to produce other content if you are looking to get into it. Well worth the money in my opinion, and you can download a demo and try it for 30 days, so it's free to try it and see what the output is. Works great on everything I've created with it.

  1. Thank you.
  2. I may be interesting in the converter functionality.
  3. Did you read the post in the link I mentioned above.
Note that it is a standard camera. There is a professional version with 100 Gb storage. I am impressed by the quality of the movies taken by an amateur / newbie. There is also a set of extra lenses etc.

Welcome to the wonderful world of web video. The easiest way to add video is to use a specialist video hosting site and link that to your ordinary web pages - by using an embedded player on your pages or simply by linking to the location of the video.

The specialist video host deals with all the technical problems.

Depending on the type and purpose of the video, you can use "free" services such as Youtube or MySpace for low resolution video; services such as Vimeo for high resolution video. There are also "professional" services. Certain services are more popular in certain countries.

Except for very special purposes, web videos should be short: 4 minutes is "long"; 10 minutes is "very long"!

This is one of my test pieces: http://uk.youtube.com/watch?v=-evjUfkRDHU&fmt=18

Most web video is supplied in Flash format, using the FLV or the VP6 codec. Many video hosting services will do the conversion into Flash. Some video is in MPEG-4; some is in Windows Media (.wmv).

The MPEG-2 produced by your camcorder is too bulky for use on the web. You'll probably also have to reduce the frame size, to reduce the file size & bit rate.

So, you'll need to edit the video, reduce the frame size, and convert it into a format acceptable to the video hosting company.

Richard

There is no answer possible without purpose.

Other than swapping with family or friends the files you are making are not really for the net - streaming them is a few - like many - years off.

Yes, I know that is a solution. Ideally Sonys picture motion browser should be used as an embedded player, but I don't know whether it is possible or even allowable, even if it follows with the camera, since the player can then be copied from the webserver.

I agree with converting it to flv as this format can stream even on servers that don't do streaming (the streaming is handled by Flash in the browser rather than the server - as far as the server can tell it's just a normal download). I made my own flv player in Flash, but I know there are pre-made streaming flash video players out there.

I also second the notion of keeping videos short, and also compressing the file size - just how small depends on your specific audience, the application, and your web host. I generally try to keep under 30 MB for short product demos, and under 100 MB for anything more in-depth, but there are always exceptions.

Not sure but isn't video a bit like images in the nets early days where it is unable to produce the same quality as the original if the original is too high in quality. In other words the offline quality amy be much higher than the online quality due to short comings in the formats that are compatible for Inet use? So there may be no real lose in quality in conversion to .flv, if sony can be converted.

Yes that is the big question.

When I click on the video link, Windows MediaPlayer is opened, but it says: "that the file can not be replayed. It may happen that the player does not support the file type or that a necessary "kodek" is not installed on the computer". But as told above, my son has Vista and it plays ok.

Are there Windows MediaPlayer Plugins like http://www.wmplugins.com/ that can be used with Windows XP?

I have inluded a link to a clip, 33.9 Mb where I speak English.
  1. How is it?
  2. Is it too short?
  3. Is it possible to live with that file size?

When I added video to a site the first time, this site was very helpful:
How to convert to Flash FLV Video and add it on your homepage - VideoHelp.com
Of the options discussed, I used the Super program to convert. Quality is a trade-off. Faster = less quality. I've also read somewhere that true streaming uses a different protocol than http and is rather expensive. The streaming protocol depends on the format. Most sites use what they call progressive download streaming through http. So, the video is downloaded, but should start playing when an adequate buffer has been reached and will continue to download when playing. If you're doing tutorials, why not convert to Flash? It's not like it's an art film in hdtv.
I used Flowplayer for the player, but the first link I posted provides a link to another player, too.

Default Re: First online video: Some questions.

I've been doing some video work just in the last couple of years. Now I convert videos to FLV using Flash (which I got with the Dreamweaver suite but have never mastered), then use JW player (http://www.jeroenwijering.com/) which is the most common player used nowadays, so they claim, and it does seems to be ubiquitous. Flowplayer seems to be similar. JW player is basically a Flash swf, and you can add the name of your video and other parameters ("flashvars") to the embed code. It can be configured and skinned in infinite ways. It doesn't need any special streaming video arrangement with the host or anything. Any hosting plan will do. The wizard on the JW site will help you get your code.

I only got into trouble when I tried to put a dozen players on a page to play audio samples. Browsers would seize up, but not every time, so I concluded that it was because I had so many on a page. But then I put all my samples in a playlist xml file attached to a single player, and all seems to be well now.

Before that, I was uploading videos to YouTube or Google Video and embedding them on the page.

I've been editing videos (from low-res ones from ordinary digital cameras, to others converted from DVD format into wmv or mp3) in Windows Movie Maker, which comes free with Windows. It's pretty intuitive, though primitive, I suppose, and someday, perhaps when I get a real digital video camera AND a new computer with a massive hard drive, I'll try something more sophisticated. I've added subtitles, made slideshows, added music, etc. basically forcing it to bend to my will. As with anything, the vision is more important than the tool, though the tool can facilitate the vision.

Hope you get lots of fun out of it, kgun.

Hi kgun

I first started working professionally with online streaming video back in 1996 when the serious surfers had super-fast 56k modems. I was producing, encoding and uploading video for the real estate industry here in Australia.

Having spent literally 1,000's of hours experimenting, configuring and encoding various formats of video streaming technology it became apparent to me that the 'windows media encoder' was the tool that was setting the standard... Even way back then.

My advice to you would be to download the 'windows media encoder' from Microsoft:
http://www.microsoft.com/windows/win...r/default.mspx
and easily encode your videos for streaming format.

I worked with 'windows media encoder' from mpeg2 standard through to mpeg4 and onto mpeg7 standards. I haven't worked with it since the turn of the century ;O) but it is obviously still setting the industry standards as evidenced by the fact that video camera's are now encoding their files using this format.

I have a sanyo video camera that encodes files to mpeg4 for video applications.

Thank you both for additional valuable input. One thought. Digital video cameras will be more and more important. Isn't it natural the these files could be streamed directly via the URL (URI), preferably with a format independent plugin?

Any comments on these technologies?

Uniform standards for video would certainly simplify things but unfortunately I don't see that any time soon. Video for the web still needs to be smaller file sizes for storage, bandwidth considerations, etc. TRUE streaming is expensive. If you want to put video on the web that's accessible to almost anyone with an internet connection, convert it to flv and "stream" it with a flash video player, some of which are mentioned above.

And Flash MX 2004 isn't THAT outdated... I used it to build this player that streams external flvs and I don't have any plugins or Sorensen Squeeze (my first attempt so be kind please...)
Billy Blaze - Streaming Videos

I used Super by eRightSoft (free) to convert the video, injected meta tags (flash needs to know duration for proper buffering and streaming) and followed an 8 part tutorial to build the player - part 1 here: gotoandlearn.com - Flash Video Basics 1

Whichever path you choose, I wish you great success.

Thank you all for your positive response. I will study your answers and the subject in further detail. It is a very interesting subject. A natural next step will be videostreaming over Ip in real time with Ip camera system technology.

But I still miss answers to some of my first questions

Are there Windows MediaPlayer Plugins like wmplugins.com - The place to find and share plug-ins, skins, and visualizations to enhance your Windows Media experience. that can be used with Windows XP?


I have inluded a link to a clip, 33.9 Mb where I speak English.
  1. How is it?
  2. Is it too short?
  3. Is it possible to live with that file size?
Again, thank you all.

I gave most of you a positive green rep point before I got the message that I had to wait before I gave a new rep point. That was a new experience to me. You can only add a fixed number of rep points within 24 hours.

kgun,

1. The videos are downloaded to the hard-drive first. Mpeg 2 is not a video streaming format. Mpeg2 is for burning to CD.
Mpeg4 is the standard for video streaming (From memory - I think also mpeg7 & mpeg9 to produce .wmv files).

2. mpeg files are windows media files, which default to 'windows media player'.


You need to download the latest version of windows media player:
http://www.microsoft.com/windows/win...1/default.aspx

It took 2 mins for me to download the 1 min video of you speaking in english. That is way too high quality for video streaming. Try converting it to mpeg4 (current standard is no longer mpeg4 but .wmv which is probably mpeg9 or later) at about 640x 480 framesize using windows media encoder:
Windows Media Encoder

640x 480 framesize would be a good starting point for you if you want to stream. There will be a marked loss in quality.

Encoding videos for video streaming is all about compromise. You need to compromise video quality for file size.


1st. Download an mpeg to avi converter:
MPEG TO AVI, MPEG TO DIVX, MPEG TO XVID, CONVERT 3GPP TO AVI
and convert your video to avi format.


2nd. Convert avi file to a streaming video file using windows media encoder:
Windows Media Encoder


3rd. Upload and enjoy...


I just tested it and converted your video to a full screen .wmv file of approx 7mb (down from your file that was about 34mb).

I temporarily uploaded the output file to my server for you to have a look:
http://www.searchengineoptimization-...e/output-1.wmv

That is probably the maximum quality that you would need for online streaming video.

Excellent answer. You deserve 20 rep points.

When I open the link in IE 6.0, it is opened directly in Windows Media Player. And the quality may be good enough?

Now it is close to delivering real time quality video streaming over Ip. Never learned so much so fast as in this thread.

Note:
  1. Sony Picture Motion Browser has a CD burning option.
  2. Does that mean that that format can be burned to a CD and viewed on a Tv without further conversion?
  3. The camera can be connected to a Tv / DVD player and viewed on a Tv in the format that is stored on the camera's harddisk.

Hi Kgun,

When I clicked the link to the short video about AJAX, it downloaded the whole file but then would not play. I used IE6 and the video placeholder displayed in the page once it had download was a Quicktime logo. But since I don't have Quicktime installed on this machine it wouldn't play.

I have Windows Media Player 11 installed though, and when I clicked SEO's link for the converted version of your AJAX video in WMV format, it opened Media Player and played perfectly.

I'm no expert in this field, so take this with a grain of salt. In regards to all of the different suggestions and your seeming desire to have multiple uses for your videos (online, streaming, download to TV, et cetera) I think you may need to produce different copies of your videos for at least some of your different purposes.

For instance, not all TVs will be able to view videos in the same formats and many TVs, won't display them at all - they will need an input device that can convert the video (such as a DVD player, video console, and so on). And the reduced quality of videos for online viewing will not burn to DVD and be playable with the quality you want.

So, one version for online streaming (or simulated streaming using FLV) and another version in a higher resolution format for downloading and burning to DVD to watch on TV.

Hope this helps.

Yes, he solved the problem. I have made a permanent linke here:

in case he deletes the link.

Thank you for your input.

If you're sure that your target web audience will have WMP installed then wmv may be easier for you at this point. However, if your target audience is the world wide web, I would highly recommend you reconsider streaming flash, for compatibility reasons. More people have flash installed than windows media player, plus WMP cannot stream the file for you - you would need an expensive hosting server to do that. Also, if you use wmv, be careful about compression methods that use codecs that may not be installed on the end users computer.

Now about the DVD - You'll need to know if your target audience needs PAL or NTSC formats (NTSC is used here in the States - my player will read both but I'm not sure that's the norm). For true DVD, you'll burn as a DVD-video (software will create an AUDIO_TS and VIDEO_TS folder which you burn to disk). There are many other options such as VCD, SVCD,etc. but this DVD-Video format will work in EVERY DVD PLAYER (PAL and NTSC exceptions as noted - sorry I can't help more here but maybe someone else can).

I started trying to learn more about video about a year ago, and now my computer is clogged up with MANY editing, converting, and burning programs. I learned a lot from the guides and forums at AfterDawn.com. I still learn something new with each new project. I'm watching this thread hoping to learn more from someone more experienced!!

  1. I have to admit that this is unknown territory to me. May be streaming Flash videos (wihout downloading) are more secure.
  2. I have also noted that WMP works best with Internet Explorer. I don't know how Flash streaming or other technologies integrates with browsers that I personally regard as more secure.

Updated information.
  1. Web tv via web camera systems is already a fact here. One man one camera on NRK Nett-TV - hastighetsmåling.
  2. The Sony camera records the vieos at exact time, so the clips can be sorted on the disk by time.
  3. The camera can be supplied with an inbuilt GPS so the movie can be placed directly on a map.
  4. So with a mobile phone / camera with ftp access to the internet, real time video streaming via the internet should be possible independent of time and place.

If you're concerned about security, you're going to have a LOT of homework to do, because nothing is 100% secure.

REAL TIME?? I have a hard time believing we'll see anything more than web-cam quality real time streaming (low frame rate, high compression rate, far below dvd quality) on mobile devices in the next few years, but if you have a link to any authority claiming otherwise I'd love to see it!!!

I imagine Rupert Murdoch would be be wanting to put himself into an 'authority' position for streaming video. Have you seen his new website Hulu - Watch your favorites. Anytime. For free. ?
Hulu - About

It appears that he too is using Macromedia Flash format to present streaming video content. I can't watch it because I am not in the U. S. so I can only imagine the quality, but I would say that after investments of more than $100 million into the project, that the quality would be pretty high.

'Real Time' is just a term used to describe the ability to update information at the same time that it is received which, as far as video streaming, has been possible for more than 10 years. 'Live Real Time' video streaming (video conferencing) was being used last century, so it is nothing new. It is only the quality and utilization that has changed. Video telephones are just one modern example of what used to be called 'video conferencing'. We even have streaming video watches.

In theory it is possible for us to 'watch the news as it happens' with a time delay of mere seconds.

The video that I encoded for you was roughly 7mb for a 1min video which translates to roughly 120kbsec. a T1 cable connection to the internet (which in Australia you can have for around $50pm) supposedly has a datarate transfer of 1.5mb sec. So, it is currently possible to stream video at a substantially higher quality than the one that I encoded for you. The trouble is... that the hosting servers need to be able to support this speed + multiple downloads.

You can also encode your video to be streamed using multiple bitrate variables. Which basically means that I encode my video to the highest quality settings with lower bitrate settings also encoded into the same file. In other words you can encode the one video to stream in 'real time' whether the end user has a 1.5mb T1 connection or a 28k modem connection.

With streaming video it is all about finding the right compromise for your specific needs and purpose.

Now I start understanding why I got a negative rep point in this Google Now Crawling and Indexing Flash Content thread.

Overhead is very important in programming. If you know the difference between C and C++ you know what I am talking about (litterature: Andrew Koening C++ Report July / August 1993 page 42 "Combining C and C++"). Minimalsim is usually using C. For some applications this overhead should be kept to a minimum. Important questions:
  1. How does Flash compress the file?
  2. Is the compression optimal quality / size tradoff?
  3. Does Flash introduce unnecessary overhead?

FLVs that can be streamed using Flash could be compressed a number of ways. Sorensen has its own codec. FFMPEG is used by some converters. The current trend is towards H.264, and from what I've seen so far its capable of excellent quality, but doesn't reduce file size as much as some of the others. For quality/size tradeoff, again it depends on your target audience. For my purposes, I need smaller file sizes so I currently use FFMPEG. If your target audience is looking for the highest quality, and has the bandwidth, you'll probably want to look into H.264

I'm not aware of any unnecessary overhead. Flash uses the end users computer resources for much of its work, and a well written Flash player is tiny in file size, many nice players I've seen are under 1MB. As far as the FLV, I can't imagine any decent converter introducing unnecessary overhead when they're trying to reduce file size

Have I read your posts? Some, but certainly not all. Which of the 5K+ would I be interested in? Security issues hurt my head, there's sooooo many things to consider, so I usually consult an expert when needed, or try to do the homework on the specific issue at hand. Flash has always had security issues to deal with, as has WMP. What are your specific concerns?

I've been installing Firefox on more computers lately, and for those who like to surf I've been adding the NoScript add-on. I still find websites that won't work properly on Firefox though, then I start up IE. For a true computer newbie, this might be a bit confusing, so I stick with IE for them. For the rest, I explain that IE is the buggy browser, and in the old days many webmasters coded websites to work with IE's bugs, and the buggy coding might not work in FF. I even have an old shopping cart hosted by Network Solutions that uses a browser-based file transfer instead of FTP, and it won't work in Firefox. It's frustrating. I'm upgrading to a new version soon and hope the coding is more compliant but we'll see.

NoScript is a godsend for those who like to surf but don't have a good feel for which websites or links to avoid. I've seen less malware problems with these users since installing NoScript and they seem to love it - I guess it makes them feel less vulnerable.

I hope you keep us posted on which delivery method you choose for your videos, why you chose it, and any insight you gather along the way.

Sites that do not render well or at all in a browser.
An internet page is a bit stream (0,1)'s to a web browser. Web browsers interpret this bit stream differently. Web browsers also support different technologies like JavaScript (the DOM) and CSS differently. The next wave of internet sites will be XML driven. As of this writing there is no browser that fully support the important XML technologies like XPath, XPointer, XInclude, XLinks and XSL(T). The XML family of technologies are very important for semantic markup and semantic linking.
If a page does not function well in Opera, that it is a clear sign that you shall be careful with the site. First of all, if a web master does not check his pages in Opera, you can doubt the skills of this webmaster. Aside from this, it may indicate that the site has malware. Worst, if it is an ecommerce site with online payment, it may be an indication of a cross server script that tries to steal your bank account number or your credit card number. Be careful if a page does not render well in Opera.

ActiveX objects and security.
An ActiveX object is Microsoft's term for a reusable software component that provides encapsulated reusable functionality. In Internet Explorer, such objects normally give client-side scripting access to operating system facilities like the file system. I had to write this in red. If you do not see the consequences yourself, I can mention that this has great potential to corrupt and damage your system. It is one way to install key-loggers that steel your credit card number. It is one way to infiltrate your operating system and install malware, worms, Trojan horses and virus on your computer.
If this is not enough arguments for you to switch to another browser, there is a least one reason in the end of 2007 to switch to Opera. It is simply also much more secure for the sole reason that it is much harder to attack and it's market share is so small that it is not the primary target for hackers and intruders.

More JavaScript (AJAX) security.
Opera requires you to set Content-Type header of a POST request using the SetRequestHeader method. Other browsers don't require it, but it's the safest approach to take to allow for all browsers.

Thank you very much. Constantly new information in this thread. I also think time works for big files of high quality.

You may find some ideas here Films. Full Length Films (A page of my own linking to full films)

See how they do it

Again thank you for your info. There is a broken image link on that site. And on the flash.html page you should replace Macromedia with Adobe to be up to date.

Your sites are an impressing resource. A portal competitor to Google in my view.

Can I ask you about your experience with the Amazon publisher program? My experience is not good so long.

Another, thing that may help, I've just found this:-

NZB is an XML-based file format for retrieving posts from NNTP (Usenet) servers. The format was conceived by the developers of the Newzbin.com Usenet Index. NZB is effective when used with search-capable websites. These websites create NZB files out of what is needed to be downloaded. Using this concept, headers would not be downloaded hence the NZB method is quicker and more bandwidth-efficient.
