Some Clips Not Rendering When Exported To DVDAS

BobWard wrote on 4/22/2011, 10:56 AM
I have about 25 events on my project timeline (VMS 10 HD).

I just renderd the project to DVDAS 5.0 and noticed that 2 of the video events are showing as a black screen in DVDAS, although the audio tracks for these 2 events are still there and play normally.

Any idea as to what caused the 2 video tracks to dissappear when the project was rendered to DVDAS as an mpeg-2 file?

It likely has to do with how you've set up the output or some toggle you have flipped.

Unfortunately, we don't really have nearly enough information to help you, since we don't even know the method you used to output your MPEG.

Also, you say that two video EVENTS are black (blank?) -- and yet you later say that two video TRACKS were not output. Are you saying that these events were the only clips on a track and that this entire track was ignored by the program?

Sorry. Wish I could see a screenshot of your program. It might be clearer what's going on.

Steve,

I have about 25 separate video clips (events) on my VMS10 timeline. About 7 of the video events are 16mm film that was digitized to avi format. These all render and play fine under VMS & DVDAS.

The remaining files are sequences from a flight simulation game that were recorded from my computer using "FRAPS' software. Two of these fiiles (events) display a black screen when the timeline cursor in DVDAS passes through that portion of the timeline that is ocupied by these two events. The audio track that is associated with these two events plays fine.

In other words, the rendered project movie is playing fine in the DVDAS Preview window (both video and audio), then when the cursor passes through these two events, the Preview window is blank (becomes black), but the audio continues playing normally.

This only happens in the rendered file that was sent from VMS 10 to DVDAS. The same events play fine on the timeline in VMS10. So it is something that is occurring during the render process.

I have fears that it may be some kind of codec issue, since I upgraded to a newer version of FRAPS about halfway through this project. Unfortunately, I know nothing about codec trouble-shooting. Is there any way to check the codec on the problem files and compare it to those on the files that play normally?

Thanks for your input.

Bob

Steve,

For added clarification, the FRAPS sequences are recorded in an avi format. They all play fine under Windows Media Player (WIN7, 64 bit).

For some reason, the 2 problem files are just not getting rendered properly when going from VMS to DVDAS.

Vegas does not support fraps natively.

I went back into VMS and did a time selection loop across one of the 2 problem events (recorded with FRAPS). So I just rendered that loop.

Opened the rendered loop in DVDAS and it played fine.

So why would it play fine when rendered separately and not play fine when it is rendered as part of the whole timeline project?

musicvid: All the other FRAP files (around 20 of them) on the timeline rendered ok in VMS10. It is odd that the other 2 got corrupted somehow. If VMS does not natively support FRAPS, why are the majority of them rendering ok?

I re-rendered the entire project and everything went fine this time around. Maybe the computer just needed a reboot for some reason.
