Audio Sync Problem

[macirish]

I'm importing VOB files from camcorder DVDs (3 1/2 inch - camcorder model unknown) - with hopes of compiling them into std 4.7GB DVDs (typically 3 small ones fit in one).

 

The input file is MPEG-2 Video Main@Main codec, AC3 audio and a Subtitle Stream in RLE format (which is empty).

 

I'm doing a 'Save as Disk Image' for output (no point burning a physical DVD).

 

The input file has an Audio Stream delay of 222ms - the output file has a delay of 1s 333ms. This results in a noticeable audio delay when people are speaking.

 

I've confirmed that my Toast Titanium 2010 is up to date (10.0.8).

 

Is this a common problem? Is there a fix? Does Toast 2011 fix this problem?

 

I'm using Media Inspector by Diego Massanti for file analysis - a really great ap - details of each export are in attached files - the output file has 'test1out' in the name.

 

Does Roxio have any feature like this?

 

Thank you.

How are you Importing into Roxio?

 

In Toast 10 - Select 'Video' then select 'DVD-Video'

 

From VIDEO_TS folder - drag and drop the 'VOB' file into the Toast window.

 

What are your Output Settings?, hint, HQ, HQ, HQ

 

In Options (lower LH corner) select the 'More' button.

 

In the Pop-up window - select 'Encoding'

 

In that window:

Video format MPEG-2

avg bit rate 4.0

Max bit rate 8.0

Motion estimation Best

Reencoding - Never

Field and Aspect ratio - Automatic

 

Audio format - Dolby Digital

data rate - Automatic

 

I don't see anything about 'HQ' - and I don't see any other 'Output Settings'.

 

Thank you for your quick reply.

What software do you have? In post #1 you state that your "Creator 2010" is upto date (and you ask about Creator 2011) and now you state you are using Toast 10.

 

Which is it? Exactly what are you doing?

[Jim_Hardin]

Sorry, can't really help you since you are not using Creator 2011

 

I see Walt moved it, and in the Correct Forum, I am sure someone will be able to assist

No, I didn't move it. MacIrish's posts are confusing

[macirish]

Duh - Toast Titanium 10.0.8 - I had the wrong forum.

 

I also used the wrong product name - so I edited the original post.

 

Thank you for moving my message. Sorry for the confusion.

 

Although - if Creator 2010 or 2011 would resolve this kind of problem - I'd upgrade.

 

Thank you.

I'm presuming that Toast merely multiplexed the video and audio and did not re-encode it. In that case I have no idea why the audio sync would change. Something to try is to use the Toast Media Browser to add the videos to the Video window. Insert the source disc and choose DVD with the top button of the Media Browser. Double-click on what appears in the browser window and drag what you want to the main window. Toast generally doesn't like to have VOBs dragged directly into the main window.

Toast Media Browser does work better - it is scanning the whole VIDEO_TS folder, as opposed to opening the folder and picking out the VOB file.

 

But, alas, no joy - the audio delay in the disc image is still increased to 1s 333ms.

 

One item of interest - the Media Browser labels the input disk as CX5500 - I tried Goggling CX5500 - but it comes back as a printer - no connection to video or DVD.

 

Thanks again - I'll followup on and try any suggestions that might fix this.

If you have MPEG Streamclip or another application that can demux the video into separate .m2v and .ac3 files then you might try that. MPEG Streamclip is free but requires Apple's QuickTime MPEG2 Playback Component ($20 from Apple Store). Once you save as those elementary streams, add just the .m2v file to the Toast window. Toast will either automatically add the matching audio stream or ask you to locate it. In this case Toast isn't doing both the demuxing and multiplexing and that may be a workaround.

 

The code that Toast displayed in the media browser is how the camcorder labeled the disc.
