Transcribing Not Working for MXF Files

Report · Nov 27, 2023

I'm on Premiere Pro 24.0.3, Windows platform, and the Transcribe source does not work with my MXF clips. It does appear to work for MP4 and MOV clips, however my main, clean audio source is on the MXF clip.

It fails to work in text-based editing mode, or even just selecting a clip and clicking into Text in a regular editing window. I click Transcribe, confirm spearate speakers, and nothing happens.

I've also had it appear to work, but displays one "transcript" that shows as blank. And, also had it look like its going to work and then reports there's no audio on the clip which is untrue, there's audio.

My work around has been to export an audio clip of the audio and then re-import that and it will transcribe my AIFF files. But, this no longer transcribes any MXF files.

Is there a bug fix or a setting adjustment I need to make? The work around works, its just a bit time consuming now that our work flow so relies on the transcription tool.

@chrisv19826297 does your MXF have multi-channel audio? By default Premiere Pro will transcribe only the first channel and if there is no dialog there then it will have an empty transcription. In that case you can right click on the clip in the Project panel and choose Re-Transcribe and you should see a drop-down menu to select which audio channel you want to transcribe.

Yes, my MXF is multi-channel, however, the audio I want transcribed is on Channel 1. When I Transcribed just now, this is what I get:

Yet, I do have audio on channel 1 on this clip:

After the failed transcription, I right clicked on the clip in the Project, but as you can see in the first screen shot, there was no option for Re-Transcribe in that drop down.

@chrisv19826297 Thanks for that extra information. In your context menu screenshot the item I'm talking about is called "Transcribe". It will change to "Re-Transcribe" once it's been transcribed, but the fact that it just says "Transcribe" is a clue that Premiere Pro doesn't think it has transcribed it yet. Clearly something else is going wrong.

Could you let me know:

Your exact version of windows (for example: Windows 10 22H2)
Your GPU make and model (for example: NVIDIA RTX 2070)
Your GPU driver version

If you're up for it, I'd like to have you install the Beta version of Premiere Pro which has some changes to the transcription pipeline that may work on your system. You can find it in the Creative Cloud desktop application, under the Beta Apps section. Installing Premiere Pro (Beta) won't touch your normal version of Premiere Pro and the two can coexist side by side. They are the same major versions (24.0.3 and 24.2) so you can open your projects in either. If transcribing works in the Beta for these files, you can still bring the project back to 24.0.3 to work once you've got the transcriptions.

OS Name: Microsoft Windows 10 Enterprise

Version: 10.0.19045 Build 19045

GPU: NVIDIA RTX A3000 Laptop GRU

I will try the Beta version here shortly. Thank you!

@mattchristensen The Premiere Pro Beta transcription does work with the MXF clips.

@chrisv19826297,

See the update to this feature request:

https://community.adobe.com/t5/premiere-pro-ideas/audio-track-selection-for-source-media-transcripti...

Lots of posts there. I assume you have a Sony camera.

We're hoping there's an update coming that will have the basics fixed.

@chrisv19826297 Great, I'm glad to hear it. It's hard to say for sure since I'm not sure exactly what the issue was with your file, but if it's what I think it is, that fix should be in the upcoming Premiere Pro 24.1 release. If not, it'll for sure be in 24.2.
