Hi there,
I'm making a DVD of Music Videos from different DVD's I own.
I've used DVD Decrypter to gather the audio and video files. The audio files were mainly AC3's and had a DELAY mentioned in the filename. I didn't know what to think of them, so I kind of ignored them.
Now that I built the DVD in scenarist, burned it on a RW and checked it on a set-top, I noticed some videos aren't sync.
Now, I've read something about "Start time to video" in scnenarist, but that will only help if the sound is ahead of video and even that wouldn't be exact if the delay isn't devidable through 40ms (PAL). And when the audio is running behind of the video, it won't help at all, right?
Now, I should mention that I converted all audio to WAVE using Besweet. This way I could use a wave-editor to change the volume and loudness of the audio to match up with each other, so I won't have to change the volume of my TVset all the time. Another reason is that i could encode them back to ac3 at all the same bitrates, which was nescessary to use them all in the same PGC.
So one thing I think i could do is edit the WAVE-files to compensate for the delay times mentioned in the filenames. Then I could re-encode them, and update. But I'm not sure wether Scenarist would except this, because the length of the audio file would change coompared to the video file, and I don't know wether that is allowed.
So what do you think is the best way to solve this problem?
I've searched the forum and the site on this, but couldn't find a straight forward description of audio delays and how to handle them. I did find a lot about Subtitle delays, even when I searched using "NOT subtitle".
Hope you can help
Yours,
Andra
