Exporting ProRes422 for MPEG-2 encoding
on Oct 19, 2008 at 1:49:58 pm

I have an application that cleans the video from unwanted noise. The source material is ProRes422 from Aja Io HD. (Betacam SP PAL 625i over component).

When I shall export the movie for the encoder, QuickTime gives me a LOT of formats to choose from.
My first idea was to (obviously) choose ProRes422, because that's the original footage.

But then there is uncompressed 8-bit and 10-bit (although Io HD uses ProRes422 internally).

And there is "none". Gives HUGE files. But is it better than choosing uncompressed 8/10 bits or even ProRes422?

Stick with the native, and excellent Prores422. There's no point in changing it or indeed up-sampling to 10bit
