Is it possible to deinterlace video with out having to run 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.
