What is the difference between ProRes422 and ProRes422HQ?
I'm curious about the difference - I'm working with HDV "24 fps" and using Compressor to remove the pulldown to allow editing in 23.98 fps using Apple ProRes422. Everything I've looked at is silent or fuzzy on which circumstances would lead you to use one or the other of these codecs. The most helpful is the following from the FCS 7 manual:
The Apple ProRes 422 (HQ) codec offers the utmost possible quality for 4:2:2 or 4:2:0 sources (without an alpha channel) and provides the following:
- Target data rate of approximately 220 Mbps (1920 x 1080 at 60i)
- Higher quality than Apple ProRes 422
Apple ProRes 422The Apple ProRes 422 codec provides the following:
- Target data rate of approximately 145 Mbps (1920 x 1080 at 60i)
- Higher quality than Apple ProRes 422 (LT)
Does anyone have an experience-based perspective on whether it's worth the larger file size - ie do you really get "higher quality" with the HQ? Obviously I want the best quality I can get, but not if it's undetectable or de minimis.
Thanks!
