I reply to this post because you have included more data into your statement then your following post.
I do not render out of After Effects (not for a while), I import my After Effects project into Premiere and render my AE comp out of Premiere.
When I simulate export out of After Effects, I get the 'add to Adobe Media Encoder Queue', which launches Media Encoder 2015.1 build 9.1.0. 163
my dynamic link server opens the 'Export Settings' window and with my export settings> format - I see your MXF OP1a and a long list of selectable presets
Did you update your Media Encoder?
I paste link to Media Encoder Help - What's New November 2015 here, but not what you are looking for pertaining to confirmation Media Encoder Help | New features summary
I paste link to Media Encoder Help - New Features Summary June 2015 here. but also not confirmation of your quest confirmation Media Encoder Help | New features summary
but, on that last link, there is another link to Export Settings Reference and I paste link here Media Encoder Help | File formats supported for export
you will read your MXF OP1a there, and think in the presets, your AVC- Intra Class 100 will have what you are looking for but I do not see a 59.94 fps though, so not exactly sure
I'm rendering (exporting) directly within After Effects because Dynamic Link and Adobe Media Encoder take significantly (two to three times) longer to render. Yes, I did update Media Encoder, but I'm trying to render (export) directly within After Effects CC 2015. I have both CC 2014 and CC 2015 installed at the same time now, and (within After Effects) you can see the MXF OP1a in this picture (CC 2014):
and you can see that it's missing in CC 2015:
I'm not sure why it is in CC 2014 but it's not in CC 2015. I appreciate the help, but I still don't understand why it's gone. I just have to render using CC 2014 to work around this, but I NEED to make sure that Adobe brings MXF OP1a back in later versions of After Effects.
thanks - i understand and see mine is now same as yours - not myself checking 2014, but processing time did increase for me also - only in H.264 codec, but i saw my gpu cpu harmony split, cpu relax and gpu spit.
choice for me was to save in 2015 as CC (12), but updating Media Encoder didn't help that backwards compatibility with respect to trying to utilizing the export harmony.
i still have AE 2014, but going the slower render route.
i wonder if its like finding the folder containing the render format in 2014 and copy and pasting the needed content into the same spot in 2015?
Please refer Link :-
The MXF OP1a format has been removed from the After Effects render queue.To export to MXF OP1a you can use media encoder .(
If you have a supported graphics card in your machine , please make sure that you are selecting GPU acceleration
in the drop-down in Media Encoder (To speed up the process )
This is a very bad "Downgrade" upgrade my CS6 >CC2017
and now VERY unhappy that I cant render MXF directly within AE
Will it come back soon ??????
