dvd sync problems from imported imovie clips in idvd

[tab75-13]

I imported clips from an imovie project into idvd and burned a dvd. Now there are audio sync problems in the dvd. What might I have done wrong? The imovie clips are from a vhs converted from analog to dv via dac-100 convertor using the 16 bit audio encoding.

the 744 kb quicktime movie .mov produced during the importing of the dv into i movie does not appear to have any audio sync problems. Could I encode this as a dvd in ffmpegX? Of course I will lose quality.

BTW, the volume of the imported dv played rather low in my computer. Could this be because I routed the audio video via RCA cables from the cable box (into which my vcr ultimately feeds) into the dac-100 analog video convertor, or is the volume likely to play lower than my PB is capable of emitting sound regardless of what component, the vcr or the cable box, is likely to be the source of the analog data into the convertor? Could the fact of the slightness of the volume have been responsible for the audio sync even though the .mov file is in sync?

And to go back to my earlier question, should I do something with the .mov file in ffmpegX in than author the dvd in sizzle etc?

A lot of questions here. Someone please help me again.

Thanks,

Apple has a knowledgebase article that says to be sure you've updated to iMovie 3.03 or later. What version are you using?

Also, there are iDVD and iMovie discussion groups at http://discussions.info.apple.com

The OP is using iMovie 3 but:

Audio may be out of sync when exporting from iMovie 4 to iDVD even if 48 kHz audio is used in all steps. A workaround is to extract audio in iMovie before exporting to iDVD (i.e. select all the clips in the iMovie timeline, select Extract Audio (can take several minutes on a long project) and send the project to iDVD.

Yes, the workaround is to extract audio, then send to iDVD. That's it! Don't move the exctracted audio in any way!

My very first burned iDVD 4 project had audio out of sync, and extracting audio in iMovie fixed it so now I routinely extract audio before sending projects to iDVD.

Ok, I am trying to what you've suggested. You know I have iMovie 3.03 right? Then I'll export to iDVD 3, or would it be better to open the iDVD in iMovie by hitting its icon? I exported instead of doing the latter last time, and I'm wondering if the process of exporting rather than just opening up iDvD in iMovie and then dragging the timelined clips into iDVD might not be responsible for the synching difficulty. But that probably sounds too hokey as the former and the later methods of working with the project in iDVD amount to the same thing--right?
In any case, why does the extracting step work, would it work (in my case)? It took me three hours to "burn" the last dvd, so once this extracting is done, it will be that long I guess before i find out what's going on.

Thanks,

ok i've wasted two perfectly good discs trying to burn/ encode the project in idvd after exporting it from imovie. I believe I know what I did wrong the 1st time, but thought I had the problem solved when after extracting audio I exported the project to idvd, but there was no audio in the finished dvd as with the preceding attempt. I am thinking now that maybe I didn't save the project after extracting the audio, so that maybe imovie sent over just the earlier version of the project which maybe just had the video portion and not also the audio. but that doesn't make sense because i thought the saved version of the project in imovie had both the video and the extracted audio clips.

also the disk ejects with the duration of the video intact but while idvd is still encoding supposedly. i thought i read some place that idvd will keep going if imovie hasn't been quitted (word?) does that sound right--(about imovie). i saw that imovie was still running in the background when i found the disc having ejected.

I am really at a dead end here and I don't want to waste another perfectly good disc (my last one).

Thank you.
