Synch issues with DVD Rebuilder Pro

[onisama]

For some reason after running this script the video is faster than the audio.


Telecide(order=1,guide=1,post=4,gthresh=25,nt=30,blend=false)
Decimate(mode=3,threshold=1.0)


Any thoughts?

I have used a similar script before w/out problems, but can't find the previous script.

Thanks,
Shannon

BTW: I am using this on SG-1, which is hybrid.

What's the entire script? I don't see a source filter.

If you are using DGIndex, what was the field operation setting?

[onisama]

Here is the entire script:


LoadPlugin("C:\Program Files\DVD-RB PRO\DGDecode.dll")
mpeg2source("C:\DOCUMENTS AND SETTINGS\SARUMON\DESKTOP\STARGATE3-1\NEW FOLDER\D2VAVS\V01.D2V")
Telecide(order=1,guide=1,post=4,gthresh=25,nt=30,blend=false)
Decimate(mode=3,threshold=1.0)
trim(50364,63893)
ConvertToYUY2()
AudioDub(BlankClip())


Thanks,

trim(50364,63893)
ConvertToYUY2()
AudioDub(BlankClip())

This isn't making any sense to me. What are you trying to do with this?

MPEG2Source() isn't going to give you any audio, so you must be recombining the demuxed audio elsewhere. But you have trimmed the video in your script!

[onisama]

I'm using DVD Rebuilder Pro. It trims the video into small chunks (I believe by VOB cell ID) and then joins them back together before muxing.

It is being encoded with CCE.

I have tried the script on 2 different computers, running two different versions of DVD-RB, using two different SG-1 discs.

The final project should be 4.3GB and is ending up around 3.7GB.

It seems like DVD-RB is expecting the video to be a certain length (size) and it is coming out of CCE smaller (shorter) than expected.

When played back the video seems to be running faster than the audio. It isn't just an offset problem, the video and audio rates are different.

I'm wondering if it isn't something to do with Decimate maybe. If I change the mode value to 1 or 2, I get different ranges of the video encoded. So instead of 2:45-5:00, it might be 3:00-5:25 (this is not a actual example, pulled those numbers out of nowhere). I may have used mode=2 last time, I'm pretty sure the telecide values were the same as what I used before.

I tried it last night with decimate left off, it was still encoding this morning. I'll check it out when I get home after work. When previewing in Vdub, leaving decimate off did seem to produce a smoother result (less jerky).

Well, you didn't address any of my points, so, good luck!

[onisama]

I thought I had addressed them.

In terms of the trim() statement: It is because of how DVD Rebuilder operates. I have 23 similar .avs files, each with a different trim range. The 23 .mpv files are (if I understand DVD-RB correctly) are individually muxed as the VOB cells and then converted back to .vob files.

I'm not using DGIndex and am not sure what it is.


Thanks for your help neuron2, I do appreciate it.

Seems to me that you should have posted your question in the DVD Rebuilder forum. Would you like me to move it for you?

[onisama]

Sure, I didn't post it there b/c I thought the problem had to do with the script itself.

Thanks,

You can't do IVTC in DVD-RB, it's as simple as that.

[onisama]

I've done it before without problems (at least 10 different discs).

It may seem like a stupid question, but why can't you IVTC in DVD-RB.

[Boulder]

DVD-RB doesn't like anything that changes the number of frames. There probably is a detailed explanation found somewhere but I don't recall where.

[onisama]

Well, does anyone have any thoughts on what to do with Sg-1 discs?

I'm watching them on a progressive display and the combing gets annoying. I thought IVTC would be the best way to take care of it (deinterlace looked like crap).

Thanks,

Do the processing manually, instead of with DVD Rebuilder.

[onisama]

I knew someone was going to say that.

I guess somethings are never easy, I'll have to go back to dif4u.

I used to do the entire process manually, but it has been so long I don't know if could do it again.

I wish I would have bought a 1080i display instead of 1080p, then interlace/telecined content wouldn't be an issue.

I could always dump a couple grand on a line doubler.
