Starting with DV video, I need to crop it to get rid of switching noise on the bottom and the blank areas on the sides for playback on an HDTV.
However, if I crop the switching noise off the bottom, this slightly expands the image and the interlace lines, and it seems removes some. Does the area with the switching noise count toward the number of interlace lines? Does this matter? Does the TV and or player expect the interlace lines to be a particular relative size and place or does it just look at fields without regard to this?
Should the video be deinterlaced first, cropped and reinterlaced or would it be better to deinterlace it with QTGMC to 59.94 progressive and upscale to 720p?
Thanks for all input.
