The problem is technically “overlapping transitions” and the only known workaround is to remove all the transitions. This is a widely known issue with Premiere editors because it’s impossible to miss it: the AAF export fails. Issue 3: Premiere cannot export an AAF with transition effects Therefore, in the AAF file, there’s no linking between the master composition and the nested sequences.”) Premiere’s help site (for version 12) does mention this issue but it’s not very clear the consequences (“Avid Media Composer does not support linking to the nested sequences.Track count only shows 1 video and 1 audio track when it should have 24 audio tracks: Note the name, start time, timecode format, and video frame rate are different. Left: Pro Tools AAF import window from a sequence with nesting Right: With nesting removed. Solution: Remove all nesting from the sequence.

Instead of providing a warning, Premiere just outputs a junk AAF. Unfortunately, the AAF format isn’t as sophisticated and only understands a filing cabinet with a bunch of papers in it – it doesn’t know what to do with the folders. A good analogy would be file folders in a filing cabinet. In semi-tech terms: Some Premiere editors use “nesting” in their sequence as an organization tool. In simple terms: When opening an AAF, you’re expecting to see a lot of tracks and instead there’s only 2 (1 video and 1 audio). Issue 2: AAFs are corrupt/missing tracks if the Premiere sequence contains nested clips Deactivate all the audio options (pan, volume, channel volume, and any other processing).Opening the sequence in 12.0.1 or later.The problem occurs in the export from Premiere. Other versions of Pro Tools or other DAWs (tested in Logic and Nuendo).Here’s what the audio looks like in Pro Tools with the bug (upper/blue track), what it should look like (lower/red track), and the distortion up close:Ĭause of the bug: Attribute data in some audio clips (I suspect it’s volume or channel volume specifically but didn’t test each parameter individually). The result is a bizarre distortion that can’t be repaired with audio correction tools. It may have a brick-wall limiter programmed in but it’s not working correctly – it interpolates the audio back to the zero crossing point. In tech terms: It incorrectly processes audio that exceeds zero (which shouldn’t be allowed anyhow) as it goes into the AAF wrapper. In simple terms: when Premiere exports an AAF (with embedded media) it messes up some of the audio, making it unusable.

This is a known bug that was fixed in Premiere version 12.0.1 (January 2018) however it’s a problem for any sequence that was used in previous versions of Premiere. Issue 1: Distortion/Garbage audio when exporting embedded AAF from Premiere Pro

The Pro Tools Import session notes will show “Pro Tools does not support import of AAF/OMF reference to multi-channel audio files” and likely other errors.

Clips may be truncated or missing completely from the timeline.

Files will be missing in Pro Tools and won’t relink (despite having the files).

Issue 4: When an AAF links to source media, Premiere points to multi-channel audio files (not supported by Pro Tools).

Issue 3: Premiere cannot export an AAF with transition effects.

Issue 2: AAFs are corrupt/missing tracks if the Premiere sequence contains nested clips.

Issue 1: Distortion/Garbage audio when exporting embedded AAF from Premiere Pro.

I’ll refer to two types of AAFs: “Embedded” and “link to source” (in Pro Tools terms) “Embed Audio” and “Separate Audio” (in Premiere’s terms). There’s bugs, features that aren’t compatible with the AAF/OMF formats, and very little information from Adobe about any of it. Adobe Premiere Pro is known among sound editors and mixers to be problematic when receiving audio by AAF (or OMF).
