If you record at C4K24 vs C4K60, with 100Mbps bitrate, the quality should be Higher if 100Mbps is constant? I've heard it's like this with cameras where if you shoot at a lower FPS at night the noise is less due to the bandwidth or bitrate w/e.
See this video at 4:00 on. He talks about dividing Bitrate by frames. Bits per second.
