If I convert from Sony A7Sii S-Log3 XAVC footage to ProRes (LT and higher), will I lose the flexibility in the colouring stages if I were to grade in ProRes?
I asked this over on Reddit , but I'm expanding my search for answers over here!
I prefer to edit, grade and finish in ProRes in Premiere CC, simply because it's much smoother and easier on my system. I work with a travel adventure Youtube channel and we have lots of footage. I choose to work with ProRes in Premiere CC because I find that working with lots of files in different formats and codecs really bogs Premiere down (waiting for thumbnails to load really gets me frustrated). I also find that editing ProRes, doing some light color grading, and EXPORTING from ProRes in Premiere a huge timesaver because I don't have to do any relinking.
Anyway, my question here is: Does converting to ProRes 'flatten' the colour data from S-Log3 XAVC footage?
Here's what I was thinking as well:
SONY footage at XAVC-S: 1920 x 1080p / 59.94 fps (50 Mbps)
Apple ProRes LT: 1920x1080p / 59.94 fps (approx. 294 Mbps)
This might be a wrong way of thinking, but wouldn't converting to a higher data rate codec retain the colour information?
Looking to get some definitive answers if possible!
