  • Avid digital cut with AWFUL audio

    I’ve looked around but haven’t seen a problem like this described anywhere.

    I did a digital cut with Xpress Pro 5.2 to my little consumer camcorder, a Canon Optura 50. I watched the beginning and end with the camcorder hooked up to my TV and it looked and sounded fine.

    When a screener watched it they said it only had about 80% of the sound. So I made another copy, this time watched it all the way through and gave them the new tape. They didn’t get back to me so I assumed it was fine. They later said that this second one had worked (although I don’t know if they just watched a piece(s) or the whole thing).

    Unfortunately, it was for my graduation screening, and at the theater there was no sound at all and they didn’t even see any audio signal from the tape. They put it into a different camcorder (Panny HVX200) and saw a signal so ran it again.

    This time the sound was fine for the first half minute or so, then it became very crackly, kind of like a bad cell phone call. It was like that through to the end. Awful to listen to, but people had traveled so far to see it I decided to let it go. It was understandable enough to get laughs in the right places, but I doubt there was a single sentence left completely unbutchered.

    I was told in passing later that the problem was that it was recorded at 32K instead of 48K. This is the part I just don’t understand.

    1) I mixed down my audio to 48K and that’s all there was on the timeline, two 48K tracks
    2) My Canon is set to record 16-bit, 48Khz audio.

    I can go to school and export it using one of their cameras, but I’d really like to know what I did wrong here, so that I can make tapes at home. And, I’d love to know why it worked at home and not at the theater. Any ideas?

    Thanks for any and all help,
    Sharon

    A quick way to make sure youre in 48k is to open your audio project settings in the settings tab. It will show you what your settings are.
