Queen On Fire At the Bowl - audio problem

[AlanPartridge]

I am currently reauthoring this title but I have a slight issue with it. For those not familiar with it the main concert has multi angles at the start which has the beginning of the concert with and without menu options overlayed. I have demuxed via vob id and everything is happy but when I come to reauthor in Scenarist it seems that the audio for the multi angle section is slightly shorter (60 frames) than the video sections for this.

Any thoughts or suggestions would be most appreciated.

Is this seamless or non-seamless multi angle? In other words do the angles have the same sound or not? I'm almost sure they do not, because this wouldn't be a problem since you have only one audio track.

Please give some more info and we'll work it out.

[AlanPartridge]

they do indeed use the same audio. The multi angle section is the intro to the concert which seamlessly leads into the rest of the concert.

Then I do not understand the problem ;) both angles will use the same audio, so the audio of the second angle cannot be shorter.

Did you reauthor a multiangle title before?

[AlanPartridge]

I have probably not described it well enough.

The two video tracks are the same length but the audio track is slightly shorter (60 frames) and therefore Scenarist throws a wobbly when trying to compile.

ah, now you're making sense. :)

Sometimes a right mouseclick in the data window data -> placeholder and then placeholder -> data helps.

If it's just a small difference you can make the video a couple of frames shorter. Go to the track editor and click on the video. In the asset browser make the video the same length as the audio (for both angles of course)

thanks very much, will try it at home tonight!! :D

You can also use delaycut and "pad" the audio with silence at the end...

that is the probably the best way to do it to maintain current durations...

to do it, just put in a - delay (in ms given 1000*(frameshort / fps))
so if 60frames short then 1000*(60/30) if NTSC or 1000*(60/25) for pal or

-2000 for NTSC or -2400 for PAL

Although, a 60frame difference is quite a bit... you sure it demuxed properly?

I did it using DIF4U and have tried it several times each with the same problem. I initially has converted the PCM into ac3 to create more space to reencode the video and I thought that this was the problemo but I did it again this morning without converting the audio and the same error occurred. I shall double check the exact error when I get home.

[D3s7]

Ah... you failed to mention it was PCM :)

Doitfast4u can't handle correction of PCM/WAV (neither can delaycut i don't think)

actually, i don't know of anything really that can w/out re-encoding to something else..

you "may" be able to use besweet and convert to ac3 then use delaycut to pad - a lot of work but it would work

if you do this, don't forget you need to modify your ifo's to correct for the change in audio streams (PCM i believe starts at 97 or A0 - ac3 is 80)
