  Audio content disappearing…

  Posted by Bethan Hughes on January 3, 2008 at 1:59 pm

  Hi,

  I’m working on a project that has been on-going since September and am suddenly experiencing problems with it for no apparent reason.

  I’ve opened the Premiere Pro project (which was last accessed at the beginning on December and there were no problems with it then) and it seems to only half-recognise the audio files.

  It shows them in the bin along with all their information, including timecode info, yet the waveform has disappeared on the timeline and no audio plays. It is obvious, though, that Premiere thinks it is playing the project correctly.

  I’ve tried using a new copy of the audio file in case the old one was corrupt but that didn’t work, and now I’m having the same problem with another audio file in the project!

  I can’t find an explanation, nor anyone else who has encountered such a problem. I have a client waiting for the finished product so I would really appreciate any help that anyone can give.

  I’m using a Canopus card, if that makes any difference?

  Thanks,
  Bethan

  Try trashing the media cache folder. Then take a long lunch while the cache files rebuild. Should work after that. Seems that the cache files can become corrupted (how, I don’t know) but rebuilding them makes everything play nice again. This has happened to us several times.

  Hi,

  Thanks for your reply.
  Before I do anything though, I just want to check that I understand what you mean (save me making any dire mistake!)…

  Do I need to actually delete the cache files? And then when I open the project it will automatically rebuild them?
  Sorry for the questions but I’m not too familiar with this sort of thing.

  I have backed-up the cache files to another external hard-drive just in case.

  Thanks,

  Bethan

  Yep – shoot the media cache files, NOT the preview files. Open Premiere and verify the location of the Media Cache Files folder – you’ll find it under preferences -> scratch disks. Trash it. Premiere should rebuild them when you relaunch it, and audio should play once again. Note the two “should”s in that sentence – caveat emptor. It’s worked for us.

  I’ve checked where you said and there doesn’t seem to be a location for Media Cache Files, only for preview files, captured files and auto-save files. I’m very afraid of deleting the wrong thing!

  Directly below Audio Preview files should be Media Cache.

  Underneath Audio Preview files there is only Conformed Audio files.

  I’ve searched my entire computer and the only Media Cache Files that I have are for Encore DVD projects.

  I really don’t know what to do.

  I am using quite an old version of Premiere Pro though – I don’t know if that makes a difference?

  [B-Hug] “I am using quite an old version of Premiere Pro though”

  How old? If 1.0 or 1.5, it is time for an upgrade.

  It’s version 1.0 and I’m very aware that it’s naff – however that doesn’t help me right now.

  Try deleting all the audio preview files…then Premiere will regenerate them.
