Camera tracks exchanged between Nuke, Maya and trackers: frame, translate, rotate and field of view per line.

Loper is a free, minimal editor for macOS that opens Camera channel file (.chan) instantly and colors every part of the file, so you find the value you need at a glance and can fix it right there. No IDE, no project to load, no gray wall of text.
