Matching Prores HQ footage from different cameras with different bit rate sources

I haven't shot yet, but I will be trying to match footage from a Canon C100 Mark ii and a Canon C300 Mark ii.  Both will record externally to Atomos recorders at 10 bit ProRes HQ.  But the Canon C100 Mark ii is 8 bit sampled up to 10 bit when recording externally.  The C300 mark ii will be 10 bit to 10 bit.  Will I come across any issues trying to use the Lumetri Color panel to automatically match colors since the footage from the C100 mark ii has been upsampled and is not native 10 bit?

Other than the "upsampled quasi-8-bit" may band a bit quicker, no. Premiere handles all media on a sequence in 32-bit float period. So in processing it's completely bit-depth 'agnostic'.

It won't matter. I use atomos ninja on nikon d800. It put the uncompressed signal into DNxHD 220x ( for my purpose... could be prores, but I have PC ). Anyway, the new 'space' from atomos is 10 bit 4.2.2 with high bitrate. The camera to SD card is mov h264 which is horrible.

The color from chip ( uncompressed) is the same 4.2.0. So, I don't gain any color quality and frankly doubt it would be visible for my work. But now that I am using the atomos stuff my editing is in a higher space and when I add graphics or effects etc. it is happier.

Just be aware, if recording sound in camera, there may be a lag in timing so slate your shots if you can.

It makes it faster to fix that lag ( for me it's 5 frames ).

it's not UPSAMPLED... there's no conversion. It's still 4.2.0 in a 4.2.2 file
