I have some MPEG2 stream video captured by EyeTV from VHS tapes. After transcoding to h.264 for AppleTV using Streamclip, there is a bar of noise along the bottom (about 10-20 lines). I don't use EyeTV to transcode VHS because it doesn't de-interlace and results in "combed" output. I know it's possible to crop the video in the initial transcoding, but is it possible AFTER transcoding, in Streamclip or Handbrake or another program, to simply crop the h.264 video without re-encoding it. i.e. to do it relatively quickly?
