  • FCP resolution/sub sampling issues

    Posted by Aivaras Seduika on April 12, 2011 at 11:03 am

    Hi guys,

    Was wondering if anyone’s had this problem before.
    We are feeding graphics in the Animation codec into FCP 6, and for some of the parts of the clip, it looks like FCP is chucking away resolution – it looks like bad colour sub sampling.
    this might explain it better (ignore the gamma changes):

    As you can see, the original clip is not the problem (when opened in quicktime player and all the others).
    When it goes into the timeline (prores 422 HQ), this happens.
    Strangely, the same input clip in another part of the timeline is perfect.
    We’ve been trying various sequence settings but no difference. It seems like an FCP render issue to be, but my FCP knowledge isn’t amazing.
    Thanks

    Force “render in high precision”.

    Thanks for your reply, but that didn’t fix it. It doesn’t seem to be related to colour bit depth, but then again I’m not an expert in fcp.
    Any other ideas?
    Thanks

    I know this is not popular but changing your sequence settings to animation codec will give much better quality compared to ProRes422 with graphics.
    But you will have to render all and loose realtime performance.

    Have you tried ProRes 444 as a sequence codec.

    I won’t ignore the gamma.

    In Fcp 7 you can change the gamma of rgb material (animation codec) freely. If working in HD change it to 2.2 before putting it in the timeline.

    Hey dudes,
    Jeremy, we’re working with FCP6, does 6 have this?

    No progress on the issue. Tried a bunch of different sequence codecs, and 2 different source files (one animation, one avid dnxhd). All the playback and render settings are for highest visual quality.
    Tried both RGB and YUV settings,
    Both of these look perfect in quicktime player, but screw up in FCP.

    Anything else left to try?
    Thanks for your time!

    [Aivaras Seduika] “Jeremy, we’re working with FCP6, does 6 have this?”

    I can’t remember. Look at the clip in the browser, is there a gamma column (you might have to make it visible by right licking at the top of any column) and can you right click and change the value?

    [Aivaras Seduika] “Both of these look perfect in quicktime player, but screw up in FCP.”

    Is this on a monitor, or just the viewer? What about field order? Does everything match there?

    Cool, will have a look for that option, thanks!

    The clips show perfect edges when they’re being played in everything other than FCP (quicktime&vlc on mac, quicktime&vlc&media player on our windows machines..)
    In FCP, in the file viewer window and the sequence viewer, and our full screen desktop display all show the pixelated edges.
    The field order is set to none for these clips in the clip browser. They’re progressive so have no fields though, so this shouldn’t make a difference.

    It’s so confusing. There’s no reason for this to be happening!

    You’d be surprised. What is your timeline set to?
