Avid export to MXF op-1a errors

[Justin Grover]

Yes I it does with mov wrapper. I’m using the latest version 8.4.4

Well hell.

One more test, mark and in-out for a 5 second span that includes those frames and export as sequential JPEG or TIFF and sse if that export is doing the same thing.

Other than that, I might suggest finding the MXF of your video and audio mixdown and opening them in Resolve to see if that is clean, if so, export MXFOPAtom 1a from there and let Avid know they have an issue.

Also, what raster size and frame rate are you exporting? 1080p/25?

I think I might try export an aap and import that into Premier and try exporting from there

[Justin Grover]

importing into Premier seems to have problems just getting the AAP into the program. Looks like I’m back to square one. Waiting for avid support to call back

[Michael Phillips]

Did you try doing a reveal file on your mixdown file, opening that MXF file in Resolve and see what it looks like? If it looks good, then try exporting MXF OPatom1a from there after bringing in audio as BWF and lining them up. I just did a quick test and Resolve sees the mixdown MXF just fine. Now whether that solves your tape clog issue or not remains to be seen.

Thanks for your replies Michael, very much appreciated.

Sorry to sound Iike complete fool but what is resolve?

[Michael Phillips]

I don’t know what codec you want to have in the MXF OP1a file, but here is an example of a mixdown file in the delivery page of Resolve. They suppport DNxHD, XDCAM, Sony MPEG flavors, etc.

It’s both a free and paid for editing and color correction software from Blackmagic. If you don’t have any experience with Resolve, it may take a bit for you to get what you need, but it is not that complicated for just this one operation.

Install Resolve Lite (free)
Import or drag and drop your mixdowns into the MediaPool
Create a timeline on the edit page and line up your video and audio
no need to color correct
go to deliver page and select outputs for MXFOPAtom1a and codec, include audio, etc.

There’s lots of tutorials out there and the manual is very well written. This is a valuable tool to have available and can come in handy for lots of different things besides the obvious kick ass color correction.

Did you guys ever find a solution to this?

I’m running Avid 8.9 and am getting errors on XDCAM MXF OP1a similar to yours. The exports have pixelated video on the upper third of the frame in random spots throughout. it makes it look like very low res video but that’s not the case….and just like you, the video is fine in the timeline and only on export is there noticeable issues – noticed using VLC player and importing/ama linking back to avid.

I’ve tried Avid 8.91, Avid 8.7.2, updating the Avid ISIS 5500 shared storage, new user profiles, exporting in different workstations…

I filed a support ticket but am hoping to get some answers sooner than later!

Hope this message reaches you since this thread is from 2015…
