I upgraded my pi4 to Bullseye and now my V2 camera is recording almost unwatchable videos. See this example:

~/picam/picam --alsadev hw:1,0 --fps 24 -v 1000000 -w 1640 -h 1232

compared to the same camera with Buster:

~/picam/picam --alsadev hw:1,0 --fps 24 -v 1000000 --mode 4 -w 1640 -h 1232

Seems white balance or contrast issue?

Could you please try adding --avcprofile high and see if it improves the image quality?

Thanks, that worked!

Thank you for your confirmation. Starting with picam version 2.0.4 released today, --avcprofile high is the default.
