URGENT HELP--ASAP

Jay Gladwell wrote on 10/7/2003, 12:47 PM
I've made a 30 second spot for a local company. Everything is the veggie file is clean as a whistle. When I render to .avi (NSTC DV, sound 48,000) I'm getting a "pop" in the voice over track in the same place that isn't there in the original. I've rendered this out four times and it keeps doing the same thing every time!

Any ideas as to what's going on here?

As usual, it's one of those the client needed this yesterday kind'a thing.

Thanks!

You don't offer much info.
Is the audio track the same 48.000 as the render?
If not, try render the audio to a new track and see if you can isolate and remove the pop there. (see the last point)

Are there any audio FXs in operation?
If yes, see if you can decrease the millisecond reaction time and see if that takes care of the pop.

Is there sound (that should be there) at that point?
Try to cut out a short sequence before an after - copy to a new track and pull down the level of the first track. (This is shooting from the hip, but you know even blind chicken can find corn - as we say in Norway).

If the pop is very short - like a click on a vinyl record, you could open the rendered file in - preferably Sound Forge, but it can be done in Vegas if you zoom in very close - and mute the few milliseconds it lasts. Then rerender that. You need to select milliseconds for the timeline and disable snapping.

Never mind, I got it. I rendered the audio only to a .wav file and brough it back into the veggie file and rendered that with the pic--worked!

Never had this happen before.

Thanks!

Could have been caused by an EQ, compressor, or illegal colors in the image. Plus a host of other things.

Spot, thanks for the info. I'll go back and take a look at those items. I am certain the colors were within legal limits. The "effects" added to the sound track were minimal (a pitch change and tad of reverb to a different track). Where the "pop" appeared was in a section of the track that had no effects.

As I said above, when I rendered the sound alone as a .wav file, there was no "pop." Then, after bringing that track into the project and rendering the final .avi there was no "pop" either.

But I will play around (now that I have the time) and see if I can't find that one elusive variable in the dreaded "host of others things" you mentioned.
