    Audio there, but blank video on import

    Hi,

    I'm attempting to import MOV files into MC.  While they play perfectly well in ordinary media players, and even AMA link well enough, the files do not play video (just a blank screen) when importing.  This has never happened before. 

    Please advise,

    DC

    If they link ok, then just link them and transcode them to whatever resolution you like. You'll wind up with the same result as if you'd imported them, and transcoding is usually faster than importing.

    also if you are on windows it might be a quick time thing as it is no longer supported in windows so as Carl said ama them and transcode them

    Strange that it should work one way but not the other.  So what are the full differences between importing and transcoding?  And how does QT no longer supported by Windows make a difference?  (Also, I still have a QT player on my system and checked that, and it works.)

    Supermandan1:

    They are two different ways of arriving at the same result. Importing creates media directly during the import process, and link & transcode creates media during the transcode part of the process. The media created each way is the same.

    Re: Audio there, but blank video on import

    Thank you.  Two things: what does QT no longer supported on Windows mean, and how this might affect me working in MC? And I'm not there just yet, but will be soon, is this likely to affect a time lapse import (sequential JPEGS, a process I've done a lot)? I guess I will find out soon enough, though just trying to act prepared.

    Hi there, can someone please take a look at the above query.  Thank you, D.

    Re: Audio there, but blank video on import

    Quicktime 7 has been EOL’d by Apple a long time ago, but classic file-import in MC was built on using the QT engine to being certain types of media in.

    AMA/Linking is a much more modern way to bring in source video files. While it CAN use QT for certain file types, it has dedicated engines for many codecs and containers.

    In general, for importing video files, linking&transcoding is more versatile and much faster than any traditional File-Import.

     

    I’m not sure if sequential JPEG uses the QT engine, but I think Linking to an image sequence is also possible.

    Re: Audio there, but blank video on import

    Ok, thank you.  So the technical answer is that transcoding is faster than importing because, while it may end up as the same 'destination' (ie., an MXF file), it could well be a different codec that gets you there?
