Thanks for the correction. I haven't ever made much use of the -ss flag in ffmpeg, so I made a wrong assumption after a quick test. Interestingly, the faster way seems to always start one frame earlier than the slower way, which would seem to be a bug (someone used 1- based indexing for the frames instead of 0-based, I'll bet).
