    DNxHD60 1280X720 source exports as DNxHD45 at 960X720

    The subject just about says it.  But, why? My usual workflow is to import via transcoding, doing my editing and then exporting to DNx because it is almost real time. Then I convert to mp4 with Handbrake.  (Both processes combined is still much faster than publishing to h264 directly, but I digress.)

    So, why do my 1280X720 DNxHD60 sources come out 960 instead of 1280?  Handbrake converts those to 960X540. I can use other utilities to convert to 1280X720 mp4s (still faster than MC|First), but I still take the resolution hit. 

    Next time, I'll see if I can transcoding to a heftier DNx and hope it works the way it should.

    How exactly are you doing those exports? Which version of MC are you on?

    Also, DNx60 is thin raster, hence the 960.

    I'm doing the exports the "normal" way - Publish to drive and select DNx as the format.  I'm using 2019.12. 

    My documentation says DNxHD60 is full raster, and using MediaInfo on the MFX files confirms the full 1280.

    New project, same MC|First version.  Imported media as DNxHD90 at 1280 X 720.  Export is again DNxHD40 and 960 X 720.

    I haven't used Avid first, but does it allow you to AMA link? Just AMA link and then transcode the footage from there. That's what I do with 4K footage for example. I set the project up to full resolution specss for the footage, then transcode to a ligther weight DNxHR(HD) for edit.

    Yes, First offers (basically) the same options as the full MC to either link or import via the Source Browser, and if linked, to Transcode from within the bin.  And, you are able to select the transcode flavor of DNx.  But, regardless of the source codec used, the DNx output option is fixed and not a full-raster vewrsion, at least at 720p. 

    I do recommend doing a transcode to DNx, even with the thin-raster output, because a DNx export is near real-time.  The h.264 is PAINFULLY slow - a 10 minute timeline taking hours.  It's much quicker to two-step through another utility.  I've had great luck converting my 960x720 DNx export to 1280x720 h.264 using Shotcut, an open source GUI/editor for ffmpeg.

    I'm currently working on a 1080p23.976 project.  I don't know yet what the output flavor will look like.

    Not so much in 2020.x, where this is handled through the Universal Media Engine now. Much faster in most cases.

    Much faster indeed! An 11 minute 1080p/23.976 project with a couple of unrendered titles took about 18 minutes at the Best setting. 

    Thank you Avid.
