Indeo Video v5 Codec for Scratching

Made lots of tests with different codecs and settings.
MJPEG has problems playing in reverse. Maybe this can be fixed as ksp wrote with keyframes every frame but I don’t have that option in AE CS5, because “Advances Settings/Keyframes” checkbox is grayed out.

Then with MPEG Streamclip exported from an AVI file with no compression to an AVI ‘Apple Cinepak’ compression with 100% quality and it works very nice, going forward and backward at different speeds.

My file is 1920 x 1080 px @ 30 fps, 921 MB and the CPU is i5, 4 GB RAM, GeForce GTX 460, Windows 7.

Didn’t get to try Plan B (image sequences).
