  • Disappearing audio problem – Yikes!

    Posted by Julie Allen on June 10, 2007 at 3:43 am

    It’s me yet again. I finished a project earlier today but didn’t get to burn it to DVD yet. Since that time, i installed a new internal hard drive and assigned it a letter.

    The drive with my project on it is an external drive. None of the files have been moved or touched. BUT – I did have to re-assign the drive letter.

    When I launched the project I had to help it link to a “rendered” file and the photoshop file with my graphics in it. That’s all. Everything looks great. Except… there isn’t any audio with my clips. None.

    I tried re-starting the computer. I tried unlinking, then re-linking the clips to their native .avi files. I’ve played some of the original files, and the audio is fine.

    I’m hoping there is a simple fix to re-link everything. Please help!

    In the Project window, scroll the columns to the right and view the Status of the silent audio clips. They should be Off-line. If so, right click on the clip in the Project window and choose Link Media.

    They are all .avi clips, my initial captures and they all say online. Should I change it?

    Is the audio on the sequence, but with no waveform? If so, then delete all of the audio preview files. That will make Premiere Pro conform them again and should bring the audio back.

    If the audio is not on the audio tracks, then you somehow deleted it, and have some serious work ahead of you to call up each clip in the source window using the “t” key, and then manually taking the audio from the source window.

    I have been having a similar problem, but unlike you, unlinking and relinking solves the problem. In your case, if re-conforming doesn’t do it, you may just want to move your files to another folder/drive and then batch capture again. Don’t delete the originals until you know you still have accurate capture info though. Depends on how many clips and tapes you have to deal with and whether or not you need to ride audio on a mixer.

    Good luck,
    Tom

    Hey, I’ve wrestled with this problem off and on, too – typically when I copy a sequence from one project to another project: the video and audio are there, but maybe a day or so later, the audio will disappear. The audio clips on the timeline will be be blank, but if I use “Reveal in Project”, the source file will have both audio and video.

    I found, by accident, a fix that might work for you that’s easier than relinking everything: I just open “Interpret Footage” for the problem clip’s source clip, click on “Conform to:” and then click on “Use Pixel Aspect Ratio from File:…” (basically, just making a change in one of the Interpret Footage parameters, and then undoing that change), and than click “OK”.

    The audio magically returns to the clip on the timeline. Why this happens, I don’t know…but it appears to return the audio to where it shoud be.

    Deleting all of the preview files worked like a charm! Thank you so very much for your insight.

    Cheers,

    Wow, videa1, I’ve been trying everything, and your strange solution was the only thing that worked. Quick and easy. Thanks. Pete

    The only problem with deleting all the previews is that if you’ve got a huge, multi-layered project, it can take a heck of a long time to regenerate them, and sometimes weird things happen when you do it.

    Plus it doesn’t always work. In my case I deleted all previews, caches, etc, unlinked, re-linked, re-booted, moved preview folders, etc. I’d dealt with this before and always wound up deleting the clips and re-dropping them into the timeline — a pain when you’ve spent time editing them. The “interpret footage” solution filled in all the instances from the problem file. BTW, I skipped the “conform to” step. Just opened “interpret footage” and hit okay. All clips immediately restored.

    I returned to a large project I’d set aside for awhile to find that hundreds of audio clips had been blanked out. The “interpret footage” solution does not work for clips unassociated with video, but I found clicking on “file info” brings the waveforms back. I just wish: a) there was a way to get all my audio back at once, and b) that I knew why this happens so I can avoid it in future! What a pain.
