Announcement: Changes to QuickTime DNxHD support in Premiere Pro 22.3
In the latest release of Premiere Pro, After Effects, and Media Encoder, we have updated the way we create QuickTime DNxHD files. Here is a brief overview of those changes, as well as a history of updates to DNxHR files.
In the fall of 2020, we made significant changes to our support for DNx media. These changes included bug fixes and additional functionality, such as support for 12-bit DNxHR 444, and brought us up-to-date with the latest DNx specification from Avid.
The downside to doing this was that DNxHR media that was made in this new version of our apps could not be used with older versions. At the time, we were able to avoid making similar changes to DNxHD, and DNxHD files created with new versions still worked with old versions.
But... (you knew there was a "but" coming, right?)
After we made the changes, our friends at Avid told us that there were problems with the files we were creating – our DNxHD output was not working properly in the current version of Avid Media Composer. To fix that, we needed to make some more changes. Unfortunately, those changes affect the DNxHD workflow that we hoped to leave untouched.
So here's the scoop on DNxHD files starting in the v22.3 release of Premiere Pro, After Effects, and Media Encoder.
- QuickTime DNxHD media generated in v22.3 or later will not be compatible with previous versions of our products – those files will be imported as audio-only.
- DNxHD SQ Thin Raster and DNxHD LB can no longer be exported with an alpha channel
- The way we create alpha channel information has changed, so the interface has changed. QuickTime DNx alpha options are now "None" and "Compressed"
- We fixed a bug where some Avid DNx media generated by newer versions of Avid Media Composer would import into our products as audio-only. If your DNx media from Avid imports as audio-only, please message me here on the Community or reach out to us on Twitter.com/adobecare
- DNxHD output from the 22.3 release and later will no longer work in the older versions of Avid Media Composer. We recommend either updating your version of Avid Media Composer or moving to a DNxHR workflow.
Hope this information helps you keep track of your workflow. Any feedback left in this thread will be brought directly to the formats team!
