Audio issue…
Hi Guys,
We shot some footage on a DVX100a. A friend who is in the business edited the production in FCP and dumped the final product to a miniDV tape using a miniDV deck. When I loaded the minidv using a $400 JVC camera and firewire to Adobe Premiere, and did a playback, the audio hisses and does the snap, crackle, pop thing. By the way, the tape played back fine on his equipment and in a screening at a theater so I know the issue is on my end.
We have the final product done and delivered, so my question is more educational than any type of crisis.
Question:
I understand that we recorded analog information (live on set) and it was converted to a digital signal and recorded to minidv. I’m under the impression that all of the digital information copied fine to my adobe premiere project and that it’s actually the conversion of that digital to analog process during playback that is where the problem actually occurs.
Sooooo, can someone give me a technical perspective, not only on how to correct the problem, but what is actually occuring internally in the equipment to create the noise? Is it a setting in Adobe Premiere that I have incorrectly set that is limiting the quality of what I can load and playback?
All help kindly appreciated!
Regards,
Hutch

This sounds as though the audio sample rates are wrong.
Two track 16-bit audio is sampled at 48KHz. Four track 12-bit audio is samples at 32KHz. Playing back at the wrong sample rate will give you all sorts of audio problems.
Check first with the editor what sample rate he edited at and then make sure you start a new project in Premier with the same settings. You should find this solves the problem.

Richard,
Makes perfect sense! Thanks very much for the assistance. I’ll check with him and test it out on my system.
