Question

My .CRM file is missing part of the audio after I accidentally linked it to a .MXF proxy file

So, I have a very weird problem. I am currently working on a big documentary project. We are working with Canon RAW files (CRM) and proxies out of the camera.

 

We had some trouble with a external harddrive. We lost some files and I had to link the files again in Premiere Pro. One proxie file (mxf) was missing and I accidentally linked it to the corresponding .CRM file. After this I found that of the 45 minutes of interview in total, the last 20 minutes are missing audio/video and I get a LOT of "frame substitution recursion attempt premiere" errors.

 

If I play the original CRM file it has the same problem. No audio after 25 minutes...

 

What happened here? I could edit this interview perfectly fine before. I still have the transcript and I can read the quotes that should be there, but are missing now.

Does anyone have an idea of how to get this missing part back?

Thanks a lot!

    Do you have all audio in the CRM file if you play it in a media player such as VLC or PotPlayer?

     

    I don´t know if any of them can playback CRM files, but the important part is to playback the file outside any Adobe app to hear if there is any audio in the CRM file to begin with.

     

    If you can hear audio in the whole file, hold down the Shift key at the same time you launch Premiere Pro. This will give you the Reset options dialog. Check the Clear media cache files and click Continue. This will delete the media cache database that probably is corrupted.

     

    Plus: It will give you the audio back.

    Minus: All your files will have to be re-conformed and that will take some time for large projects.

     

    While the re-conforming is in progress, avoid to do anything with the project until it´s done. Starting to edit/playback files while they are conforming can cause issues like you have, iow that portions of the audio goes silent.

    Thanks for your reply. I tried to play the CRM in VLC. The is no image, but the sound has the same problem. It stops after 26 minutes...

     

    It is really strange.

    If you see the problem in a non-Adobe app as well the CRM file seems to have an issue that cannot be resolved. The issue here is probably not the file itself, the problem seems to be a glitch in the camera during recording. Try other software players. I don´t think anyone of them will find the audio though.

     

    If you playback the MXF file in VLC, do you hear audio all 45 minutes? If yes, it is possible to extract the audio to a WAV file and use that file as the audio source in Premiere Pro.

    Never easy to troubleshoot premiere problems from a distance so please tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs, etc.

     

    Wondering if the original full rez file (.mxf) file has been corrupted in which case not sure if there's a solution.  You might run a disk utility (like diskfirstaid and diskwarrior on the mac) on the hard drive to see if that helps.  Also, maybe try and transcode the file to a "mezzanine format" like prores...

     

    And although it may be too late, always important that you have your source media backed up at least a couple of times...  Every hard drive will fail.  It's a question of when not if...

    I am using a Windows 11 PC with Premiere version 25.1. The computer has 64gb RAM, a Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz processor and a Nvidia Geforce RTX 2070 Super.

     

    The original .mxf was created in camera but the file is missing like I said, because of a hardware crash. Yes we have a backup of everything now...

    The RAW files are still there luckily, but something went obvisously wrong. The only thing I can think of is that I linked the MXF file to a RAW file and now it got somehow corrupted. Is that something you have seen before?

    The weird thing is that our backup of the RAW file (which has never been used before) is also missing it's audio after 26 minutes.

    I have nog idea what could be the problem. Hope it can still be fixed!

    Frankly, I have no idea what’s going on, but I can’t suggest a few things
    to try. Try deleting your cache files in premiere. Try creating a new
    premier project and importing the file.

    Maybe try playing the file in another program like resolve or VLC.

    Let us know if anything helps
