Delay of audio when printing to tape. Video good.

Hi,

When printing to tape a seemingly good rendered avi (plays perfectly on computer), the first 2.5 min (approx) of audio are not being recorded (or are not loud enough to hear). As I said, the sound is great when played through Media Player but on tape...no joy.

One clue, I originally had a 6 minute project which, when rendered and printinted to tape, sounded great throughout. I then decided to add a short intro to the clip. The project is of the birth of my daughter and I decided to preface it with a little intro "speech". Since I added this "speech" clip to the front of the previously okay project, the entire audio from the new clip and about 15 secs at the beginning of the original project just aren't there or at least aren't audible.

The "speech" audio is quieter. Could it be that there is a gain threshold that has to be met before audio is recorded. In the original project I have mellow music that fades in and the "speech" audio is kinda quiet (but still audible when it's individual source-clip is played).

Any help would be greatly appreciated!

p.s. I am using VF1 with both VC2.0 and/or VC2.5 (doesn't seem to matter), printing to a sony DV camera. AVI renders look and sound great when played on the computer.

More info....I have now stripped the "speech" clip off the original project and rendered it to .avi as a separate project. All good. I then printed this to tape. Still all good.

It appears as though the "blanking out" of the audio at the beginning of my original project is directly related to the video fade-in. If the fade-in takes 5 seconds to get to "full in", the audio is blanked out for 5 secs. If I then change the video fade-in to 1 second, the audio is blanked out for one sec coming on abruptly when the video fade-in is complete.

The weirdest aspect of this is that the rendered .avi looks and sounds great when played on the computer using Media Player. It's only when printed to tape that this crap occurs.

None of the other cross-fades, nor the fade-out at the end has the same problem.

Any ideas?

Check out the Print to Tape Preferences where you'll find 2 delays that can be modified. The ? help explains them.

Yeah, but those delays affect the project as a whole (in my understanding). Why would my video fade-in work perfectly well while the audio doesn't come in at all until the video fade-in is complete?

Deef,

Are you going to answer my question?

Thanks
