  • Too early for DVD StudioPro with FCP

    Posted by Alan Lacey on April 9, 2005 at 6:36 am

    I’m still building and experimenting with my first Mac and FCP(4.5HD) system and am nearing the end of the first project on it.

    It’s about 80 mins in length, palDV,(a lot of pip) but mainly graphics. I’ve not got the time to play with DVDsp, even the easy settings at the moment, so am planning to export the m2v from compressor and work on the DVD in ‘DVD-lab’ on the PC with which I’m familiar.

    I’ve done some export tests from FCP and having established that everything must be rendered in order to get a clean m2v, all is well.

    Compressor seems only to export PCM aiff files that DVD-lab isn’t interested in, so I’m converting them to stereo wavs. So far so good, the trouble is that when I compile a short test dvd there is a 55 frame A/V synch problem. Audio on the dvd is 55 fms late!

    I’d be really grateful to hear if anyone’s got any ideas on what is going wrong here. I know I can shift all my audio forward by the required duration on the TL but would like to understand what’s happening.

    Thanks to all

    I would try doing the conversion to WAV in quicktime on the mac if you aren’t already or use A-pack on the mac to make ac3 files. Or try exporting directly from FCP timeline as a WAV file (I’m not sure if this works)

    Exporting to MPEG2 from FCP via Compressor always causes sync issues, so don’t even bother!

    Export a Quicktime from FCP first (either self contained or not), then drop that file in Compressor and convert to MPEG2 there. You can do the audio compression elsewhere, although I am not sure how many formats DVD Studio Pro accepts (if you are going to use this application). Just to make sure that your audio stays in sync, it might be a good idea to convert audio in Compressor at the same time. With the default setting it will be uncompressed AIFF so there should be no quality issues if you want to re-export this to another format. Also don’t forget that you can export to AC3 via the A.Pack application which should have been installed together with DVD SP. All DVD production systems will accept AC3 (but dont forget that this is a compressed audio format).

    Don’t touch compressor in FCP, use “export using quicktime conversion” from the timeline – it works perfectly.

    Thanks for all guys, a lot of help.

    It was Forge that caused the problems.

    What kind of problems do you guys get using Compressor from FCP?

    I only ask because after burning 100+ DVD’s in that manner, we have had no sync issues at all to deal with. (I don’t really like tying up FCP for the duration of the encode, though…)

    Just wondering…

    [Todd Beabout] “What kind of problems do you guys get using Compressor from FCP?

    I only ask because after burning 100+ DVD’s in that manner, we have had no sync issues at all to deal with.”

    I’m new to FCP (AVID editor) and I’ve spent the last day trying all three options listed in this thread with a :45 minute piece and I have had no sync issues with any outputs.

    Exporting as a Non-Self Contained “Quicktime Movie” (using the Current Sequence settings) versus exporting “Using Quicktime Conversion” made more sense – no need to re-encode anything before it hits the Compressor encode to MPEG-2 as far as I can tell; just create a QT reference file.

    There was no hiccup in the Export using Compressor either (I also HAD to try it when someone says it doesn’t work :>) because I was exporting Interview SELECTS on DVD to the writer and was using the TimeCode Reader filter on top of all the clips which caused FCP to Render a Self-Contained QT even when using exporting “Using QuickTime Movie” and not checking “Self-Contained”. I’m assuming FCP does this because the added filter had to be “rendered” for export even though the timeline was still “grey” – I definitely couldn’t trim clips in RT before the Export with this filter on – dropped frames like crazy.

    The resulting QT “Reference” file was 7 GB so I thought it would be great if I could avoid that step and go directly to Compressor – it worked OK. But it’s clear that it ties up both FCP and Compressor so it made me wonder; are there problems if there is not enough memory on-board to run both apps in this manner. I’ve got 2GB ram in my box.
