Film Glitchy on Youtube

    My film exported from FCP into Quicktime runs smoothly. There are no glitches for the whole 9 minutes. Sadly my settings were on interlaced as that is the setting on my camera. Still I have no problem until I upload it to Youtube. When I do so the film glitches a lot. How can I avoid this?

    Hi Adam,

    My girlfriend uploaded and deleted the clip this morning. I'm trying a few different options like lowering the quality and size. One thing was that the footage was shot interlaced and so i edited it that way with pro res 422. when i exported it to quicktime it was perfectly fine but once we uploaded it it would skip a few frames in each shot. when i tried to de-interlace my clips they looked even worse in fcp.

    This may sound mad but... Try INCREASING the quality:

    Encode the movie which I guess was shot at 1080i, down to 1280x720, doing a de-interlace whilst your at it, and encoding it at 5 Mbits (5000kbps) as an H.264. The result may not play back smoothly, but it delivers all the required quality that YouTube extracts in order to make its movie.

    Depending on your compression software, find a way to use 2-pass encoding ((or multipass in compressor IIRC), which essentially pre-scans the movie looking for difficult bits which require more work (sudden pans, zooms, exposure changes, transitions, cuts).

    Interlaced footage can pose problems for web encoding software that's not expecting it, as any 'comb' edges around movement create exactly the sort of detail that the compression software gets distracted by, thus dropping frames or lowering quality to devote resources to the interlace edges.
