Before I render, all my photos, video and Boris 3D slides look perfect. After I render, everything is pixelated in squares and there's a purple line at the top of my sequence. After I export the sequence as a Quicktime movie, everything is still pixelated in little squares. There are post-rendering screen shots below so you can see what I mean.


I've checked all my settings and everything appears to be correct. Here's what I've done so far:


- All video footage shot on Canon 5D Mark II at 29.97 and converted to Apple XDCAM EX 1080p30 (35Mb/s VBR) clips

- All photographs shot with same camera. Kept as JPGs.

- Sequence settings are:

          Frame size - 1920 x 1080 HDTV1080i 16:9

          Pixel Aspect Ratio - Square

          Unchecked Anamorphic 16:9 box

          Field dominance - None

          Editing timebase - 29.97

          Compressor - XDCAM EX 1080p30 (35Mb/s VBR)

          Quality - 100%

          Audio rate - 48Khz

          Depth - 16 bit

          Config - Channel grouped


In this same project, I have a few sequences of video interviews synced with an external audio source, and those sequences look perfectly fine until I add Boris 3D text or regular text over them.


Does anyone know what's happening and how I can fix this? I've read other forum Q&As and can't find an answer.


Thanks in advance for your help.

    Try converting the video to ProRes422 (LT would be fine but if you want try "regular").


    Also you might find TIFFs work better as well.

    Click anywhere on your timeline and type Command + 0 {zero}  to see your sequence settings. Click on the Render Control tab and either report those settings or take a screen shot and post those settings here.


    You might try rendering  with the Render Control Codec set to ProRes and see if that gives any improvement.

    I would do a test first with a couple of clips and photos.

    When the going gets weird, the weird delete FCP preferences.


    Try using Digital Rebellion's FCP manager to delete them. Note you need to reset your custom settings (eg scratch disk, autosave vault, etc...)


    Go ahead and make a backup of them before you delete them. That way if deleting them makes no difference you can restore your previous settings.

    Preference Manager will give you the option of creating a backup of your current FCS prefs.


    With FCP or any FCS apps NOT running, start Pref Mgr and have it make a backup of all your preferences - then have it delete your current ones.


    Start FCP, reset your scratch disk and your autosave vault (the autosave is usually in your user folder under FCP documents) and open the project.


    Do things work better?


    If they do work better, be happy.


    If not, quit FCP, launch Pref Manager and restore your prefs. Then, come back here and we'll keep asking questions.
