Now in Beta: Improved support for NVIDIA Blackwell Architecture and MXF

In v25.3 of Premiere, After Effects, and Media Encoder, support was added for hardware acceleration of 10-bit 4:2:2 media in both H.264 and HEVC codecs in MP4 and MOV containers. 

Now in beta is an update to this support, adding hardware acceleration to files in the MXF container. 

This support applies to customers using NVIDIA’s Blackwell Architecture GPU in computers with Intel or AMD CPUs. It will also support customers using NVIDIA’s upcoming RTX Spark chip. 

We’d love to get your feedback on this expanded support for Blackwell Architecture!

    Trying to playback 4K MXF clip from Canon R5C just gives Frame substitution recursion attempt aborting after multiple attempts error and eventually Premiere crashing if you leave the play head to MXF clip. Then there is also the bug of Warp Stabilizer crashing Premiere when applied to ALL-I footage from Mavic 4 Pro. So many bugs in the recent beta versions.

    Hi ​@Kirsi21888295ykon 

    Thanks for stopping by the Premiere Beta forums! Appreciate you reporting in about this issue and including that screenshot with some spec details. I believe you’re using Windows based on the screenshot ‘D:\’ pathing. We’d like to ask a few more details to help us troubleshoot with our bug report details.

    1) Windows 11/10 and which exact driver version & build? Studio recommended.
    2) Which was the last version & build of Premiere that these clips had playback as expected?
    3) Can we confirm the version & build of Premiere Beta you’re currently using? v26.5 had an update today.
    4) May we see the media properties on one of the clips? A screenshot will do.
    5) Did any Beta build previously play the clips back as expected?

    It may be best in fact if we request a sample media file and a simplified project in order to test this further. We can provide a Dropbox upload link in a DM or you can DM us a link to these from wherever you prefer.

    Sorry for any frustrations and hope to help!
    Katie

    In version 27.5.0.077 this bug seems to have been fixed. Now in the same project MXF files work.
