echo gets progressively worse

videoproduce wrote on 11/18/2005, 12:01 PM

I began editing a project in Vegas 5. Sound was fine during editing. I used DVD Architect to make the DVD. As I was watching the finished DVD, an echo began to develop and got worse through the rest of the video. The problem began at around the 5 minute mark. There was no echo on the original DV tape. The DVD is approximately 48 minutes.

Any suggestions are welcome as I have to try to get this fixed over the weekend.

Thanks in advance.

An echo, or it's getting out of sync?
If it's an echo and still in sync, you must have dropped an echo on an FX bus, or made a duplicate audio track that is offset. However, this wouldn't explain it getting progressively worse.
You might want to upload a veg somewhere that someone can look at to see if you've got FX inserted somewhere, or a duplicate audio track.

Thanks for the help.

The video stays in sync throughout. It definitly is an echo. The audio is mono so it's all on one track.

Where can I post the veg?

Thanks

Without changing anything else, does the echo occur when viewing the veg in Vegas, or only from the finished DVD?

Have you perhaps managed to send the audio to two devices?
Does it just get worse as you play it or is the amount of echo relative to how far along the T/L you are?

My strong suspicion is that you have more than one sound track. One of these is a duplicate and is shifted. I have had similar things happen when I import the same video more than once, and Vegas creates a new track. This could sound fine during editing, because you may have muted the track or used V volume controls or something else to suppress the extra track (or tracks). What happens on the track vs. what happens during rendering depends a lot on how you have your audio routed (are you using the audio buss?).

Anyway, let us know if you have more than one audio track, and take a look to see if the audio is duplicated.

Thank you everyone for pitching in.

The problem occured because the gain was changed. I don't know how I did that but I did. There was a mono sound track. I saw a blue line there but I didn't know enough to know what is was. DSE, thanks for helping me look more closely at that. Everything is working beautifully now and now I can rerender the file.

Thanks again for the help and making me a better Vegas user.
