[Mike Kahn] “2) compressor”
Compressor is always my first stop when I’m trying to do a weird software conversion. I’m often surprised by results that range from excellent to way better than I had any right to expect. As the results from stranger format/frame rate conversions get lower, I then go to Motion or AE or Shake. In the end, the one that sucks the least wins.
That said, going from 720P in any decent codec to 1080i ProRes or uncompressed is usually pretty good via Compressor. Run tests, though, YMMV.
