capture ok...audio sync trouble in authoring

[dalfan678]

I'm using a Dazzle DVC 150, capturing analog from VHS with MovieMaker 5...only because I can't get any other piece of capture software to recognize the DVC 150.

Anyway, I'm capturing in MPEG 2 at 720x480. A two-hour movie splits into two capture files. The captures look and sound fine, but when I try to author a DVD using DVD Complete or ULEAD Movie Factory 3, the audio gets out of sync by several seconds.

Any ideas on a fix? Lower bit-rate on the capture? Different encoding on the audio capture? Capture in AVI instead (if so...what bitrate?)? Anyone got a line on a better capture software that will actually recognize the DVC 150? I'm a very frustrated newbie right now.....

Thanks in advance.

I'm having a similar problem with TMPGEnc DVD Author. Question posted in the Authoring forum:

https://www.videohelp.com/forum/viewtopic.php?t=201267

Since I've successfully burned direct MPEG-2 captures to DVD in the past, and since the MPEG-2 clips are perfectly synced throughout, I'm wondering if the length of the clips is the problem for the authoring program or if the program is somehow not putting the chapter cuts in the right place for the audio AND the video.

For example, when I captured, the first clip is 10 minutes in length, the second is 45 minutes, and the third is 10 minutes. Where I'm losing sync the worst is on the clip that's 45 minutes with the sync being OK at the beginning of the clip which gets progressively worse the deeper into the clip you go (again, only on the VOBs, not on the original clips).

I'm running the Authoring program on an old P3 750 and I was thinking maybe that was the problem but I monitored perfmon throughout the authoring process and it never went over 75% and available memory was never fully utilized.

What speed system are you running?

Let me know what you find out. I'm about to get a new computer anyway but I'm curious as to what's causing the problem here.

I'm on a P4, 2.2ghz, 512mb DDR.

I thought it might be a chaptering problem as well...so I tried to author a DVD with no chapters, basic menu, no background audio on menus, etc. Still got out-of-sync.

Strange thing is that, prior to this problem, I did two VHS captures that DID NOT split into multiple capture files (one was about 50 min of video, the other about 85 min of video). When I authored these, the project came out great. No audio problems whatsoever.

Leads me to believe the problem lies with the combining of the capture files in the DVD authoring/conversion process....but the fix alludes me. I wonder if there is there something to be done in the capture process that would alleviate the problem.

One more question (but no answer yet, sorry). How many chapters are you trying to create? In my case, I have clips that are 10 minutes, 45 minutes, and 10 minutes and I'm creating chapters about every 5 minutes. I wonder if chapters too close together is a problem.

Also, are you doing VBR or CBR?

Update on this...finally found a work-around.

Instead of trying to capture mpeg-2 video, captured as AVI in MovieStar 5 (I still cannot get ANY other program to recognize my DVC 150). After capture, imported the AVI files into ULEAD Movie Factory 3, and did editing, added chapters, menus, etc. Because of the AVI file size, the project was going to be too big for one DVD+R, so I produced the project as a VIDEO-TS project. Then used DVD-Shrink to compress the VIDEO-TS to 4.4gb (only had to compress a little bit), and then used burning program to burn to DVD. Great quality...audio in perfect sync.

Tried a second project the same way...this one was small enough that I did not need to compress using DVD-Shrink, so I let Movie Factory 3 convert and burn itself...again, great quality and no sync problems.

A lot of steps and different programs, though...
