I’m playing with video speeds.
So far making AVI files with MJPEG and the result is not a very smooth change in video speeds.
Tried u7angels rev_vid.v4p. It has a small AVI with Indeo Video v5 codec and it works very nice.
How can i make a AVI with Indeo Video v5 codec? Installed Ligos Indeo Codec 5.11 http://www.free-codecs.com/indeo_codec_download.htm and After Effects CS5, Premier CS5 or MPEG Streamclip don’t have any Indeo option under AVI. ¿Does it have a different name? ¿What other software can do this?
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.
