Transcript doesn't work on certain videos.

[Editing Ninja]

Hello, I have a weird problem. I got a few videos from my client which are 1 hour podcasts (clean, english audio) and the transcript doesn't work for those videos. My client provided me those videos with a google drive, but since the transcript didn't work on them I also downloaded those videos directly from YouTube and the transcript still doesn;t work on them. 

Transcript works perfectly for other videos. I even have put on the same timeline podcast video from my client and another random video and then I transcripted timeline; it only shows me the texts for the second video.

I'm attaching properties of the podcast video clip:

Very strange. "How" does it not work? It transcribes and there's nothing there? Or what?

I don't think anbyone has reported this issue.

I can't imagine anything other than the audio that would be an issue.

Screenshots of the problem areas (e.g. empty transcript tab) might help.

This only happens on these (podcasts) videos. Audio is super clear, cause they are podcasts recorded on hi-end gear.

Other videos works perfectly.

I don't see anything that should prevent transcription.

It hangs on the rendering audio?

Try picking A1 rather than Mix.

What is that on V2, an adjustment layer?

Try removing the in/out markers (yes, shouldn't matter; just trying anything), and the item on V2. Does that maker any difference?

If none of that helps (and I'm not optimistic), I would export as audio only to a wav (or really anything), and import that to try. What is the format of the audio?

I've created a new timeline, without anything, just a video clip and still doesn't work. I used A1 intead of MIX too.

And on the same timeline, when I've put next to that video different video clip - it works, only for the new one.

I'm taking a guess here:  There's something preventing the source audio from demuxing (demultiplexing) when it's sent for transcription and Premiere Pro thinks it's silent.

I'd try one of two things so that you can delivery your edits with transcription and/or captions:

• Once you've locked picture, transcode all source video to ProRes 422 LT by selecting all of the clips in the Sequence, right-click, and choose Render and Replace.  Use the "Individual Clips" option.  Assuming that process completes as expected, transcribe the Sequence.
• Once you've locked picture, export the audio only as a WAV or AIF file.  For example, export "Episode_17_audio_only.wav".  Import this and place it into a lower video track while disabling all of the original clip audio.  To disable all of the oringal audio quickly, do a non-linked selection of the MP4 audio clip boundaries and then choose Clip > Enable.  Then transcribe the Sequence.

Warren, that was my thought as well, but you have addressed it more clearly.

Ninja, I'd do the test I proposed now, just to see.
