    Same as source ama/mxf export would be cool.

    I like ama file export, but shouldnt there be a same as source option or something?

    Im using windows so i dislike exporting quicktime.

    thx

    You can't have SAS from AMA. The AMA plugin is needed to access the various AMA sources. How could that translate into a single file?

    RAW footage for example has to be processed before playback by the AMA plugin.

    You have to transcode to a standalone codec before you can do SAS and your output file needs to have the same codec for each clip and its unlikley all your AMA sources are the same codec.

    Premieres idea of linking clips like AMA (they call that import) and then doing a transcode in the background to a proxy file is ideal. Your clips then can be the source or the transcoded copy by your choice.

    The OP is talking about AMA _export_, asking for a way to export native media that way, same as source, so without re-transcoding.

    Re: Same as source ama/mxf would be cool.

    The problem is with exporting long projects.

    I'm working on a 90minute doc in uhd.  I always render as I work.

    And exporting the timeline, takes about 20-25 minutes with ama export (then I compress with AME).  And the cpu usage is at 100% on all cores the entire time when ama exporting.

    There really shouldnt be much cpu processing if I am rendering my work as I go along.

    I am also rendering to my 2tb nvme drive, so there shoud be a method to export super quickly if everything on my timeline is rendered.  Quicktime same as source seems to give me issues (all black, etc)

     

    This why in the past ive suggested being able to render the entire timeline to a nvme drive, even if the clips don't really require rendering.  I want my entire timeline "cached" to my nvme drive, and when its time to export, i want to happen super quickly.

     

    One can get 2tb nvme drives for $350 now.  I want my entire timeline on this drive (dnxhr_lb uhd) without having to consolidate my media or mixing down to it (rendering as I work is fine).  And then the timeline should export in seconds with this data rate (if there was a media processor sas option).

    If the soure is native media then it should conslidate to a target drive. If not a Transcode can be used.

    This sounds like the cache that Resolve uses and I think Premiere has something similar.

    But in MC I just get to the codec I need via a transcode and then work with that.

    Re: Same as source ama/mxf would be cool.

    Back to the topic and I don't want to beat a dead horse.

    And I shouldnt be complaining about exporting a 82 min uhd timeline to dnxhr_sq via media processor in 15-16mins.

    But its just strange to me that a fully rendered timeline is using so much cpu (although im glad my $ was well spent) to export.

    Ideally, a fully rendered timeline should mainly use disk speed, and little cpu.

    Which brings me to another point.  Is is there a "generation loss" or recompression going on when exporting ama (to lb or sq) since its not same as source?

    This is why I think it would be good to just render the entire timeline while working to a specific setting, and when its time to export, bam, super quick.  I guess thats what same as source quicktime was (it doesnt work with the dnxhr codecs), but Avid hasnt implemented this method with media processor.

    I should focus on editing but im addicted to peak performance :/
