Hi,

I am about to do some colour grading and have come across the new ProRes 4:4:4:4, but I'm reading a lot of people are saying only use 4:4:4:4 if your going to use the Alpha channel.

My understanding for the Alpha channel is that it has nothing to do with colour grading, more for compositing etc.

Any input would be appreciated

Correct, the alpha channel is for matte information. You don't need it, but it won't hurt the color timing.

Hi Mark,

Yeah that is spot on. I would take John's advice, like he mentions it won't hurt the colour timing.

I've also heard good things about the ProRes 4:4:4:4 though I'm still yet to use it for anything.

Hope all goes well.

Jay
