    P2 files audio gain adjustment causes crashes

    BVX3001 Community Member

      I'm fairly new to shooting and editing P2 files. Whenever I try to adjust the audio gain on any such clip it immediately crashes Premiere (5.0.3). Other files adjust flawlessly. I see someone brought this up last year but the suggested changing of audio preferences for source channel mapping from stereo to "Use file" had no effect.  Is there a solution for CS5 users? Has this been solved in 5.5?   Going thru Soundbooth is a tedious, time-consuming workaround.

       

      Thanks in advance for any clues.

          It's a known bug, and unfortunately, it was not solved in CS5. It was fixed for CS5.5, however.

           

          Are you saying it's happening with mono-only clips, also? I thought/seem to remember this only affecting clips where the mono audio was remapped to stereo.

            OK, I might have found a workaround. If you are indeed talking about mono audio mapped to stereo, there's a fairly simple solution: instead of using Audio Gain on a clip in a sequence, simply use it a on clip in the bin/Project Panel instead. To do this, just select the clips you want to use Audio Gain on, and then go to Clip > Audio Options > Audio Gain (CS5.5 has added this to the right-click menu). Even when mapped to stereo, there is no crash--at least, not in my testing. It seems to be OK even when the clips are already used in a sequence; note that it won't affect clips already in the sequence, though.

             

            Does that work for you? Just did a quick test here...

              Thanks for the quick help Colin, that approach does indeed provide a usable workaround. My usual trial and error to find the ideal amount of boost might take a while that way, but less than jumping to Sb and back. (Great, another known bug that I have to pay for a fix to get back to CS4 capability, eh?)

              Yes, I have 4 mono signals mapped as two stereo pairs, as my Pana HPX-300 only seems to let me do even when I need only one mono track.

               

              Thanks again.

                If you only need the one mono track, you can disable all the others simply by unchecking them in the Audio Channels dialog; no need to remap, necessarily. When you drop the mono audio into a sequence with a stereo master track, it'll be automatically routed to both stereo output channels. Is that functionally what you're trying to achieve?

                  That's good to remember, but rather than do that in Premiere countless times, I'd like to do it once in the camera, then enable recording tracks 3 & 4 only when needed. Unfortunately I can't find that anywhere as an option. I'd guess it might be a P2 file thing - a question for another forum no doubt.

                  Thanks again.

                    No need to do it countless times; just select all the clips right after import (it's important to do it before they're used in a sequence) and you can apply the remapping/channel change to all the clips at once.

                     

                    I don't think there's a way to do it in camera; I believe it's just part of the P2 spec.
