Yeah, the first thing I do with the files is use FFMPEG to slow the play rate from 60fps to 30fps, and also to add a time marker to each frame.  For example, here's the command to do that on a 640x120 clip (17424 being the fps):

Code: [Select]
ffmpeg -i ChronosFile1.mp4 -r 30
 -vf "setpts=(2/1)*PTS,
 drawtext=fontfile=Arial.ttf: expansion=normal:
   text='%{eif\:n*1000/17424\:d}.%{eif\:mod(n*1000/17424*100,100)\:d\:2}ms':
   x=(w-tw-5): y=5: fontcolor=white: box=1: boxcolor=0x00000099: fontsize=25"
 -an -y ChronosFile1Post.mp4

For anyone looking to just do time-warping I found a brilliant open-source project that does only that: slowmoVideo.

The same functionality exists in Adobe After Effects as the "Timewarp" effect.

I primarily want to splice and alter playback speed (i.e., slow down around key points, speed up elsewhere) of the MP4s coming off this camera.  So something like Adobe Premier seems like complex overkill.

What Windows software would you recommend for this sort of post-processing?
