DVD problem?

[arkclk]

I'm working on a DVD project, have captured video with no missing frames, rendered the videos into MPEG2 files, and everything looks fine on the PC. When I burn the video to DVD, and view it on my TV, once every three or four minutes, it seems a frame is missing. The video seems to skip forward. I've burnt the video to DVD-RW discs.

Any ideas as to what could cause this problem? Again, this problem is not present when I view the project on the PC.
Thanks much

This isn't going to help you that much...

FYI- It's not unusual for a (slightly?) corrupt MPEG to play OK, and then to have problems show-up later when it's re-rendered or re-multiplexed to the final DVD format. This makes it hard to determine the root-cause of the problem! Are your audio & video out of sync after the frames are dropped? This is quite common.

Depending on what format your raw videos are... Maybe you can wait 'till the final step for Video Studio to automatically render the MPEG. (MPEGs are not meant to be edited. If you're doing that, it could be the cause of the corruption.)

Some people have had some luck using VideoReDo ($50) to repair corrupted MPEGs. The trick is to "fix" them before the problem shows-up... before Video Studio has thrown-away the apparently-corrupt frames.

It could also just be your DVD player not liking RW disks. There are a lot of little issues with RW media on DVD stand alone players, some simply refuse to play them at all.
Try another player, different brand/model and see if the problem repeats.

Thanks to both of you for the advice. I tried burning the project to a regular disc rather than the RW and got the same results.

Should I try to go from the VSP files to a DV file, then to a MPEG file? I have sections of video that are only 4 or 5 seconds with a transition between each one so I'm wondering if MPEG can handle all of this edit work.

I'm wondering if trying to create a MPEG file from the VSP is creating the problem????

Thanks to anyone who can help with this.

It sounds like you are editing in MPEG. If you are putting in transitions in the length of time you say this may be the culprit. How are you capturing the video?

Download the CD/DVD burning pack:

Check this option 'Enable buffer underrun protection' before burning. And try to burn at the lowest speed possible. It's a good thing that you're using RW discs - you could just erase it and try again, although I do agree with heinz-oz that your player might not like RW discs.

There is no need to go to a DV AVI file first and then render to mpeg. Vs can handle it like it is. I presume you capture to DV AVI for editing, right.

What is the duration of your transitions between these short clips? Don't think this has a bearing though. You haven't given us any details on your system spec's or how you captured the clips. Do you have enough HD space, memory?

Did you install any VS updates, The burning patch? What speed did you burn at?

Thanks again for the help.

I captured into many .AVI files. Edited these files into .VSP files, then combined about 20 .VSP files to create one MPEG file. The original .AVI files show:
Frame rate: 29.970 fps
Data rate: 3512.11 kbps
Compression: DV Video Encoder - type 1

The .AVI files are on a 160 gig external hard drive with 30 gigs of free space. I'm currently writting the output to a 60 gig internal drive with 30 gigs of free space.

Over the past couple of hours I took a couple of the .VSP files, created a DV file, then from there created a DVD MPEG file and this seemed to work. For this latest burn, I selected the DVD format (Create Video File option) rather than the MPEG2 format that I had been selecting. I'm not sure what the difference is, but this seemed to work well, although I'm not sure why.

I'm burning at 2X, have not installed any patches, and the transitions are only 1 second long. The problems do not show up in the transitions.

Thanks again for the help.
