Shane:
Thank you so much for replying. Here are what I think are the answers to your questions (I’m a bit of a noob at this stuff):
When I look in sequence settings, I see Apple ProRes 422 as both the render codec and the QuickTime video setting. I think I have it for the clip settings, too as I did a Log and Transfer to pull in the clips (and my Apple trainer said that converting to Prores would ultimately give me greater flexibility and/or quality).
I am testing this on Sanyo HD TV. The DVD is formatted as a 16:9 letterbox. It was shot in 16:9 and is being edited in 16:9. So, I’m not stretching 4:3. The stretching is slight, but noticeable.
I think I want both square and rectangular pixels depending on output. I’m burning the DVD for the friend (rectangular) and creating mpgs (square) for online view by out-of-state family. Also, because computer monitors work in square pixels, isn’t that what I want while editing?
In Compressor, I’m outputting to MPEG-2 for a DVD. Wouldn’t that convert to rectangular?
