export XDCAM HD rendered in ProRes
I am trying to export an XDCAM HD sequence that I rendered in ProRes using the render control setting for the timeline. When I export a reference file with the same setting as the timeline which is 5 minutes long the export message say it will take 40 minutes to write the audio and video. The timeline is completely rendered and I’m exporting on a MacPro 2.66 with four gigs of ram.
Any ideas?
thanks Dave -

its beacuse you are working with a Long GOP format
a reference movie to a Long GOP format just doesn’t work Dave, don’t ask me why.
it seems basically that the first clip is referenced but all subsequent clips need to be rendered/conformed to a single Long GOP structure … theres no benefit to creating a reference movie with this format. -
But if I render into XDCAM HD – MPEG and conform the timeline the export is under a minute as it has been for the last year. Do you think it’s re-conforming from ProRes back to XDCAM HD – MPEG on the export?

Not having done this… I would imagine that the export function is telling FCP that you want to export XDHD. That would explain what is going on.
You can create another sequence in ProRes and render that one. Then export like you want and your issue should go away.

If you render and “conform” the sequnece in XDCAM HD then you are creating a single (render) file instance of the entire sequence … if you then export a ref. movie of that then you are just creating a movie with a pointer to a single (Long GOP) render file. As i said (guessed) the first file is referenced but subsequent files are then conformed to a single Long GOP file and embeded within the ref. movie …. so yes, thats my point:

the files are being conformed, not referenced … hence ref. movies dont seem support Long GOP formats.
