Hey everyone, Im fairly new to video editing and what not but I noticed something while I was exporting one of my latest projects during the playback. I was noticing these lines through the frame as a transition effect was activating. Here are some screen shots to show you what im seeing.


Im seeing this each time the transition is happening. The transition is Dip to Color Dissolve acting as a "flash" in between shots. This doesnt occur while Im playing the sequence within FCP 7 but when I export the sequence I see this in the playback in quicktime. The original video was shot with iPhone 5's at 1920x1080 HD, Codecs: H.264, AAC, and total bit rate 17,323. Im running FCP 7.0.3. My exporting is quicktime conversion, compression type: H.264, Frame rate current, key frames automatic, compression quality best, Encoding best quality, no frame reordering, size 1920x1080. Hopefully its something simple and can be adjusted.


Thanks in advance,


Final Cut Pro 7, Mac OS X (10.6.8)

        First of all, don't edit with H264 it's a delivery codec and FCP will give youproblems. Convert your iphone footage to pro res and edit with that, then export as Quicktime Movie, not Quicktime conversion, and then use Compressor to export to your delivery format whatever that is.

    Regards your lines in the video, it looks like interlacing to me.

    More than likely your sequence settings are interlaced because your H264 is interlaced.
    You could try duplicating your sequence and changing the sequence interlace setting to none(click seq/command+zero) and then render. But H264 files in FC7 do not place nice.

    Can you do it anyway? yes

    Are there numerous posts similar to David's suggesting you don't? yes

    Are you almost guaranteed to have problems? yes


    Panning can also cause interlacing issues as the camera can have a hard time keeping up with the motion depending on the frame rate of the movies you are shooting.
