  • Render Files Management / Avoiding Re-Encoding from Render Files During Export

    Posted by Bernhard G. on January 6, 2012 at 11:32 am

    Hello,

    please do anyone know for sure how FCP-X handles render files?
    (Nothing found in the manual nor in the forums…)
    To be more specific:

    Under which circumstances will FCP-X re-process every frame during export?

    To explain what I mean:
    If I have a ProResHQ project that needs to be rendered,
    the project is already rendered and I export directly into a ProResHQ file,
    then I would assume FCP-X takes the rendered data and copy it into a new quicktime file
    without to process and re-encode all the frames again.

    BUT:
    If I export into a different codec than the project is:

    will FCP-X re-process all the frames (without encoding ProResHQ render files),
    and encode them directly to the target codec?

    OR

    will FCP-X take the rendered ProResHQ data,
    decode and re-encode them to the target codec,
    leading to a (in this case rather small) quality loss?

    Thank You and kind regards,
    Bernhard

    I’m not sure of the specific answers regarding renders, but there is no longer a project format setting as there was in FCP 7. There is a render format, but you can now have different native codecs on the same timeline (like a mixture of various ProRes codecs) and you will not need to render. I presume when you export this sort of a timeline as “current settings”, they will be encoded to the format specified in the render option the project settings.
