Compression

[gotmlifbk]

Does anyone know where I can find some info about compressing a video for view on the web. I am using Ulead 11+, and when I create my video for the web, it takes 4 -5 minutes to stream before you can view it. It has both audio and video. I am using the Sorenson 3, to create the .mov.

My video is about 3 minutes long.

Yes, I know that I need to view the forum but there are over 200 pages and I do not have the time to find the one that will help.

All I am asking is for some information about compressing my video.

Any info is greatly appreciated.

Thanks JK

The filesize is determined by bitrate (and playing time). A lower bitrate will give you a smaller file (and lower quality).

You can use the following formula to estimate file size:
File Size in MB = (Bitrate in kbps x Playing Time in minutes) / 140

Got your response, not quite what I am looking for.

What I need is some insight to the different compression for audio and video within video 11 interface. It has 24 bit integer, streaming, and the video size, for example. How do I know what to use if it is not explained. This is what I am looking for an explanation about the output of a video.

Could you direct me in this direction.

Thanks JK

...my video for the web... to create the .mov... What I need is some insight to the different compression for audio and video within video 11 interface. It has 24 bit integer, streaming, and the video size, for example.

What do you mean by "for the web"? Are you going to put it on a webpage? On YouTube? Make it available for download?

I don't have Video Studio on this system, and I don't know what the MOV options are... Maybe someone else will jump-in and explain the options.

If you don't understand the terminology, there is a glossary at afterdawn.com, or you can check Wikipedia, etc.

There are many different formats and many variations/options for each format. The exact format details are constrained by the play back software/system. For example, if you are making a DVD, there are very specific requirements. On the other hand, if you are going to play it on your computer, you can use any format for which you have a CODEC. If you want it to play on many different computers, then you need to use a common-computer format like WMA, or make sure that each user's computer has the correct software or CODEC. If you are uploading the video to a site like YouTube, they have their standards & requirements listed on the site.

Yes, I mean for the web. Thank you for your honesty.

I am working on trying to solve myself, so far a little luck.

Thanks again JK

That doesn't get you far on an all volunteer web board...

Simply in VS when you're going to produce your video file, (Share>Create Video File), select Custom, then in the Save As File Type drop down, select the QuickTime (MOV) format. Then press the Options. You can find several Codecs including Sorenson. I just ran a quick test using the video samples supplied in VS.

I used Sorenson Video CODEC, Quality-80%, 24bit Color Depth, then in there is a box beneath this Prepare for internet streaming. Place a check in that box, and the drop-down menu is activated. From that make your choice. I would use the Fast Start. Then choose your Audio compression.

Here's the properties of one of the tests I performed:

If you take advantage of the free upgrade to VS 11.5+ then on the share tab you have a new option to render the video in a format suitable for use on YouTube.

We have also provided a few other suggested settings as a series of stickies at the top of the Members Samples forum.
