    Error link or import .m2ts files

    Hi everybody,
    All worked fine since years on Media composer First 2018.7, but I get an error message since 3 weeks, whenever I try to read, link or import  .m2ts files (h.264 /  AC-3 256kbs) in my project HD 1080. It seems to be understood as a wrong format. But it still works good with .mov or .mp4

    Error message : Assertion failed: normalCaching || smallCaching
    File: s:\coresw\core\src\filesys\corewinfilelocator.c, Line: 1382

    and then this second message :

    Exception: std::exception, what:ACF call failed:_pUncompressedAudioProvider->GetAudioFormat(track, i, &formatTable.sampleFormat, &formatTable.sampleWidth, &formatTable.bitsPerSample), error code 0xa0000068, file s:\coresw\ame\src\consumers\devices\amapro

    I've tried to delete msmFMID.pmr and msmMMOB.mdb files. I've also tried to install other versions of MC (2018.12.3 or 21.9.0) but it doesn't works better.
    On MC 21.9, I get this error message : File: e: \ws2\workspace\MC\Release_Installer_Git\Win_Build\coresw\core\src\filesys\corewinfilelocator.c, Line: 1440

    An idea ? Thanks for help !

    Hello, 

    One thought I have... MPEG-2 Transport Stream (m2ts) uses Variable Bit rate (VBR) instead of CBR (Constant Bit Rate). Not sure how well MC supports media with a variable bit rate particularly on a low spec system.

    You could try rebuilding the AMA management folder by deleting all the folders inside "AMA METADATA FOLDERS". Here is the path: C:\Users\Public\Documents\Avid Media Composer\AMA Management 

    On another note, Your system specs just are not good enough to run Media Composer. 6GB of RAM is far below the recommended minimum 16GB. I wouldn't put too much effort into troubleshooting on such a low spec system.

    If you can't figure out a way to link the .m2t files, you might be able to convert them to .mov or .mp4. Shutter Encoder is a good free choice if you don't have a compression program available.

    Re: Error link or import .m2ts files

    Thanks for your ideas Philip. I'll try your AMA solution.

    I tried to run MC under Win 8 mod tonight and it works further. It makes me think that a W10 update gave this new trouble a short time ago.

    I know 6GB of RAM is not recommanded to run MC, but it worked fine up to now with my specs.

    Camoscato, thanks for this issue.

    I used to work this way 4 years ago when MC First did'nt accept m2ts with AC3 audio.

    But since, it worked OK with linking or importing m2ts directly.... until month of january 2022 !

    Oh okay, in that case just rollback your OS. There is no point troubleshooting this further. It just won't work with your hardware.
