Is it possible to deinterlace video with out having to run it through and re-encoding it?Nope, I don't think so. Either you interpolate what the missing lines look like (result: having to create whole new full-resolution frames, which require re-compression since these are NEW frames), you combine the two fields (result: new frames are created from combining two fields, which require re-compression since these are NEW frames), or you simply halve the resolution (result: the frames need to be altered so that you don't see a jump of one pixel between frames, which requires creation of new frames at a new resolution, which required re-compression since these are, again, NEW frames).
Sorry, you're kind of up a creek. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin)
