    I have sony vegas pro 9. I was wondering for a football highlight video with slow motion and other little things what is better for rendering. CBR or VBR(two pass)? Thanks.
    Standard def video.

  2. VBR is more efficient in terms of quality vs size (the tradeoff is the extra rendering time). Though the difference probably won't be so big with football highlights. If you're putting less than an hour on a single layer DVD you might as well use CBR and save time.

    Some key questions.

    1. Source format
    2. Length of highlight video
    3. Destination. DVD? Youtube? Blu-Ray?

  5. Then save time: use CBR at about 9000 kbps.

    When I make an AVI copy that I put on the computer to put over our school channel I have a question about rendering. What would give me a little better quality or would it even? Interleave every frame or every .250 sec default?

  7. I like to interleave audio with each frame. There's no difference in quality.

    None? What does it do then?

  9. When audio and video are multiplexed within a file you have a little video, a little audio, a little video, a little audio, etc. Interleaving effects the size of the video and audio chunks.

    1 frame of video
    1 frame's worth of audio
    1 frame of video
    1 frame's worth of audio
    1 frame of video
    1 frame's worth of audio
    ...
    vs:

    4 frames of video
    4 frames' worth of audio
    4 frames of video
    4 frames' worth of audio
    4 frames of video
    4 frames' worth of audio
    ...
