Hello
I am following the video tutorial on how to create a video file for youtube. I followed the instructions, set the frame size to 320x240, select DivX codec, even set the frame rate to just 24kbps (according to the calculator in the DivX configuration page in VideoStudio, that would make my 5 minute video a 6MB file). After rendering, the file is over 60MB!!
I checked the properties and its data rate is 198kbps so it seems to have ignored my settings.
Any idea why it does that? Could it be the audio settings? (I left them as default, maybe that is DVD quality?)
Also, most of my videos are in widescreen 16:9 format, PAL. How will they look like if I use 320x240? Will youtube stretch them?
Thanks
DivX video files are too big

I've never made a YouTube video, so I'm only guessing here....
24kbps is very low, and Video Studio probably can't go that low. (BTW- this is bitrate, not framerate, and it is the bitrate the determines the file size.) I've never even heard of an audio file with a bitrate that low!
The 60MB file might be due to uncompressed LPCM audio. (Uncompressed LPCM stereo is about 1500kbps, depending on the sample rate and bit-depth.)
It think 5 minutes and 60MB works out to a combined audio & video bitrate of about 1700 kbps... I'm not 100% sure about my calculations... That would actually be reasonable for a DivX file if the audio were compressed and most of that bitrate was devoted to video. But, that bitrate is too high for streaming over the internet via YouTube.
Just for comparison, 5000-6000kbps plus about 200kbps for Dolby audio is typical for commercial DVDs (MPEG-2). This will give you about 1.5 hours on a single-layer 4.35 GB DVD, or about 3 hours on a double-layer DVD. Since DivX (MPEG-4) is more efficient than MPEG-2, you can use a lower bitrate (smaller file) for the same quality.

When you create a divx file the default is PCM uncompressed audio, change the audio to Mpeg layer 3 and use a bit-rate of about 128kbs.
You select the audio in the screen right before you would go into the divx encoder settings. I think it's right after you click on AVI -> Options. The audio selection drop-down box should be in that screen. That will considerably reduce the file size. Using pcm audio defeats the purpose of creating a divx file in the first place.
