    AMA waveform sync exceptions

    Tyre-kicking the new waveform sync with a couple of clips on the timeline: it goes 'preparing', then 'analyzing' then...boom, Crash... exception!

    The clips are AMA 1080p50 MP4 AVC from a Canon camcorder and a Canon EOS dslr, nothing very difficult I reckon.

    Tried both Avid generic and QT plug-in, same result.

    Are there limitations I should be aware of, like AMA files unsupported for waveform sync ? Do I really have to take the transcode to proxy res route, even for a simple 2 cam project ?

    Re: AMA waveform sync exceptions

    This problem is not permanent: with another set of AMA files, I got no crash/exception [but the resulting sync map wasn't good].

    In another project, I tried the feature with a 4-cam T/L (one 45 min long clip per track); no AMA, plain DNxHD MXF media: also crash/exception at the end of the 'analyzing' phase...(in the meantime I also realized that this exception had corrupted my profile: probably the profile was in an inconsistent state when I had to force killing MC; I created a new clean profile since)

    For the time being, I will continue doing manual sync (visual sync based on waveform then frame-accurate verification based on video) and create group clips from there....

    If others are experiencing T/L waveform sync crashes, please chime in, otherwise I will consider this as a specific problem here Sad and won't spend time contacting support.

    Hi, Just a suggestion: could you try it after trimming those 45 min clips way down on the timeline? Would it still crash, I wonder, would it complete much faster ?

    I tried with the "short" 5 min clips from the first attempt/project, and trimmed them to about 1 min:

    No change, same crash at the end of the analysis process

    Re: AMA waveform sync exceptions

    Good to know. I suggest we all try to keep track of things like this in one easily found thread. The Good and the

    not so good. 

    I suppose you could do an audio mix down of the AVC media, and try that just to see if the crashes cease.

    If it is successful, it’s a clue. 

    Limitations is the right question.

    Maybe it would be good troubleshooting for you to have at least one successful Waveform sync from Timeline done, so as to ensure that your system functions fine regarding this new tool.

    Perhaps, Avid.com might provide some sample media to download as part of a free lesson/how-to on this new tool.

    -> The process finished OK at least once, and the incorrect sync that resulted may of course be due to the nature or quality of the audio tracks involved.

    So there is nothing wrong with my system (pretty recent and with a fresh 2018.12 installation) I reckon. I have to move forward with workarounds, and will revive this thread if I have relevant updates.
