Transcription Process Fails if no Audio on Channel 1

Report · Apr 07, 2023

I’m working on a project using the beta build 23.4. The reason I’m working beta is use the text-driven edit function.

I keep getting sn error that audio can’t be muted in order to make a transcript.

After a week of trying to figure why it wasn’t creating source file transcripts (which are needed to do text-driven video editing), I’ve discovered a possible reason:

The sources have 4 tracks of audio.

1 - Nothing

2 - sync (camera mic)

3 - sync (lav)

4 - sync (boom)

I best source is Lav on 3.

I tried soloing track 3 - no dice.

I tried all modify/audio channels on the clip, reducing it to a single source - no dice.

After creating an intermediate file with a single mono audio track, it does work.

So … I suspect that the when the transcript is created, it uses Track 1 of the audio. With 4 (track 1 silent), the process doesn’t seem to see audio.

TEMP SOLUTION:

Using EditReady I was easily able to rewrap the assets and strip the empty channel 1 out. This maintained file time code, name, and metadata. However, it requires a lot of work to redo all the sequence stringouts as the audio channels have changed.

You could (also as a workaround) nest your source clip in a sequence and transcribe that sequence statically (Generate static transcript). That lets you select the audio track you want to transcribe. After that you can use the newly nested sequence as source and it should work.
