FFV1 v3 4:2:0 8-bit = 260-270 FPS, 902 MB
FFV1 V3 4:2:0 10-bit = 180-186 FPS, 922 MB
ProRes 4:2:2 HQ 10-bit = 114 FPS, 936 MB
Cineform FS1 4:2:2 10-bit = 480 FPS, 732 MB
Cineform FS2 4:2:2 10-bit = 470 FPS, 1.16 GB
Cineform FS3 4:2:2 10-bit = 470 FPS, 1.24 GB
x264 Lossless 4:2:0 8-bit Preset Medium = 100-130 FPS, 942 MB
x264 Lossless 4:2:0 8-bit Preset Slow = 70-87 FPS, 940 MB
x264 Lossless 4:2:2 10-bit Preset Medium = 70-95 FPS, 1.74 GB
x264 Lossless 4:2:2 10-bit Preset Slow = 50-66 FPS, 1.73 GB
