BUG: Floodlight V2 bitrate too low (bad compression)

[shawnsi]

Describe the bug

I've noticed that among 3 types of cameras I use only my floodlight v2 models exhibit lower bitrate on all streams. This happens on 2 models I use but can't be reproduced on a doorbell v2 or either cam v4 I also use regularly.

Currently, I have this configuration for cam quality:

            - QUALITY_BACK_PATIO=HD1500 # floodlight v2
            - QUALITY_SOUTH_GARDEN=HD1500 # floodlight v2
            - QUALITY_FRONT_PORCH=HD500
            - QUALITY_UNDER_DECK=HD500
            - QUALITY_FRONT_DOORBELL=HD500

The actual bitrate of the floodlights appears to be 3-4x lower than the other cams. This is the case in storage measured for recordings and also when viewing bitrate statistics of the streams in vlc.

Is the fact that this logging still says "SD" in quality prefix significant? These lines are after the cam was restarted to force reconnection.

Anything else I can do to debug bitrate/compression issues on the floodlight v2? Can I control key frame interval in anyway? That might mitigate the compression artifacts I'm fighting as well.
