Rendering 4:2:0 to Apple Prores 4:2:2
Hi yesterday I was talking to an editor friend of mine and he said me this:
“…normally I got material from XDCAM (4:2:0 / 35Mbits) after i’ve done my edit I render it to Apple Prores 4:2:2…”
And I was thinking why do you do that? Because your native material color compression is 4:2:0, render it to 4:2:2 will only increase the file size, not more color information.
Is this is right??
What really happens??Cheers!!

Hi Rui,
if you just cut and export, it makes no sense, but if yu have to render yes. All the effects, color correction, graphics, etc will hold much better. If you compress back to 420, a lot of what you have added in post will just disappear.
Also the rendering will be much shorter when exporting to an intraframe codec instead of to a GOP based one.
Most of the people around do this. The perfect thing would be to be able o export to uncompress, but it makes too big files.
When ever you export try to do it with the best quality codec you can. Mostly if the movie have to be processed again for any other application.
Before rendering set “render all YUV material in High Precision”.

To further explain what Rafael is saying….
You can go into your User Preferences – Render Control and set the render codec to Apple ProRes 422 (HDV, XDCAM EX/HD/HD422), and this will render anything you need rendering into ProRes 422.
