Loss in quality when colour correcting/ grading footage
I’m working on footage shot on a Canon 7D in Premiere Pro. I find when I push the grade, there’s a significant loss in quality. I don’t believe I’m pushing anything too much in post, just lots of small tweaks like shadows/highlights, contrast, curves etc (I make a point to never push very far with anything) but I’m still noticing a loss in quality after exporting in the ‘Match Source – High Bitrate’ preset.
Is there anything I can do to keep the quality high? transcode the footage or export in different settings? or should I avoid certain tweaks when grading?

That happens when you have compressed h264 8 bit footage. Make sure your footage is lit properly and don’t push it too much.

here’s one thing to try: enable the HDR tick box if you’re using lumetri panel.
sometimes it blows out stuff and enabling HDR will get you some more range without a blowout.

Converting to ProRes or DNxHD…10-bit codecs…will allow you to push things a little more, as you now are in a 10-bit space, and not 8 bit (even though the footage still is 8-bit) You can push things a LITTLE more. But no, H.264 doesn’t lend itself to drastic color grading.

Friends don’t let friends shoot to H264 footage 🙂
Good tips on lighting. I’ve had to use Canon footage with my RED and thankfully they were all day shots.
