Depending on the DVD you’re making, I’d avoid the DV50 codec. If you are just making a “standard” DVD for playback in a DVD player, it will work just fine. If you’re making a data DVD with a Quicktime file for playback on a computer, avoid the DV50 codec since most if not all PC’s cannot play it back DV50 without a fairly costly codec plugin.
Also, if you make a Quicktime file for playback, make sure that you enable the “High Quality” box in the Quicktime player’s properties tab. It will make a huge difference in how good the picture looks. Better yet, go into the Quicktime preferences and enable the “Use high quality video setting when available” setting. Then, when you make a Quicktime movie, the high quality flag will be automatically set.
Using the animation codec with it’s very high data rate can easily choke an older PC or one that cannot sustain playback/processing of high data rates.
Also rendering in YCrCb is the same as rendering in YUV. That’s the option given in Final Cut’s preferences I believe.
