Conformed audio has no sound
Has anyone experienced a situation in Premiere Pro where you import a batch of video files and, after Premiere has conformed the audio on the files, the conformed files have no sound? It’s happening to about a third of them.
I’ve checked the original files and they still have sound, so why does the mandatory up-converting/conforming of the audio seem to eliminate the sound on some of the clips within Premiere? No files have been moved.
I’m currently working with hundreds of video files at the moment amounting to around 200GB so I don’t want to have to start tricking around with them one file at a time. Any suggestions very gratefully received.

Is your firewire deck connected to your PC?

Nope, no firewire deck and no external drives. Everything is on-board the internal drives as quality QuickTime files for off-line editing. That’s the perculiar thing. It took nearly 15 hours for the audio encoding to run its cycle, causing me to miss work the following morning as Premiere wouldn’t allow me to switch off until it had finished. I’m not a great fan of forced encoding, especially as it doesn’t seem to do a good job of the conversion. If I knew why a percentage of the conformed audio is silent I might be able to find a work-around.

So, you are using Quicktime as your source files? If so, that may be the issue. Can you try importing an AVI clip to see if you can repeat the problem?

I’ve since found out that others have the same problem when importing large batches of files, especially if you don’t walk away and leave the computer untouched until its finished conforming. This is a feature in both 1.5 and 2.0. I’ve since deleted all the conformed audio and project files and am now editing from scratch in smaller chunks and it seems to be working with all conformed audio now having sound. Must be a glitch in the software tied to system resources. Many thanks for the advice and I’ll just stick to smaller projects with Premiere Pro in future.
