    deep techie question

     Hey,

    If i render a clip 2;1, then mix it down, does it recompress again  at 2:1 or does it use the media already created at that resolution to make the mixdown?

     

    thanks

    I'm pretty sure it 'copies' it.  I did some difference matte tests in Photoshop a while ago to try and answer this very question, and the mixed-down and unmixed-down frames were identical (at least visually)

    Anecdotally, the speed of mixing down rendered vs. unrendered effects would also support this conclusion - but I guess we'd need an Avid developer to see this thread before we get a definitive answer.

    It only recompresses it if you add another composite layer before doing the mixdown. The same is true with a submaster effect - if you drop it over a master clip and do a render, it should just copy the media of the master clip into the submaster render.
