I have looked at motion.conf settings now, for ffmpeg video creation, and have successfully run each option timelapse, ghost pixels and mpg all with streaming as a simultaneous option - all at the same time and the Pi's coped! I'm impressed!<\/span><\/p>\n

The cameras have identical format specs, but the Pi Noir has no Infra Red filter, so has a slightly redder tint to the video.<\/p>\n

It was asking a lot for the Pi to run all options at once, I reckon, but they managed it at slightly different performance levels despite being technically identical for kernel, updates, firmware, raspi-conf settings etc.<\/p>\n

The cameras v4l outputs are identical both for PiNoir and PiBlanc as I have named them. I have identical Share folders set up on each camera also to see the output files remotely. Running for each camera:<\/p>\n

v4l2-ctl --all >> \/Share\/motion\/NoirSpec.txt<\/span><\/p>\n

v4l2-ctl --all >> \/Share\/motion\/BlancSpec.txt<\/span><\/p>\n

I diff'd the two files once copied to Mint, and got not differences:<\/p>\n

The Pi's were set next to each other, with (slight angle diffs due to the housings) and motion set running as a daemon almost exactly together to generate time lapses of the same scenes:<\/p>\n
