Decoding Canon Printer ICC Profile Names

Work in progress.

Canon ICC Profile Naming Conventions

ICC Profiles from Canon follows a simple naming convention. The file always (with few exceptions) starts with Canon, and then the printer model number/name (or printer series), the paper/media type in short form sometimes with a number corresponding to the quality (usually on the scale 1-5, where the lower number is the highest quality, and the higher number is the lowest quality) of the slider in the Print Quality Dialog on your Operating System.

Convert pngs to mp4

This FFmpeg command reads images named frame_[4 char digit].png and converts it to an mp4 using the h264 encoding which Twitter accepts. The bitrate is set to 5M to reduce blocking as much as possible while keeping the size small.

ffmpeg -framerate 10 -i frame_%04d.png -c:v h264_qsv -b:v 5M video.mp4

Convert and scale an existing mp4 to 1080:

ffmpeg -i input.mp4 -c:v h264_qsv -vf: scale=1080:-1 -b:v 5M output.mp4
