HDCAM-SR 444 Masters& ProRes 444
My normal workflow with 4:2:2 HDCAM masters involves using ProRes HQ. I pretty much use ProRes HQ for nearly everything I do. It’s great, and I’ve never had a complaint except for a PC user who couldn’t open a file (long time ago).
Recently, a client has given us HDCAM-SR 444 masters. Is there any reason to not use ProRes 444 for this (capture & output)? Capturing these Uncompressed requires a faster fibre array than what I currently possess. I can handle about 200MB/s currently which isn’t enough. Thoughts?

HDcam tapes are recorded at 8 bit 3:1:1, not 4:2:2.
While ProRes4444 will do fine for this, unless you are planning for keying/ or heavy compositing the HQ format you are using offers as much as can be recorded on SR tape.
Try for yourself to see if there is a difference, but unless you have scopes out I doubt you will see a difference.

Sorry I meant HDCAM-SR. I was referring to HD workflows in general, whatever their color space may be. I guess I could compare a couple still frames in Photoshop or something. I was just curious if anyone had any opinions or is using ProRes 444 in a broadcast environment. I have used ProRes HQ for a while now, but this is the first time I’ve had to deal with 444 material.
I am not doing any keying or compositing. Minor edits, then laying back to tape.
