Subtitle bug when exporting video when previous export was an audio only file in Premiere Pro

Upvoted.

As noted before, I am running PR 24.0.3 on Win 10. 

I do not get exactly the same pattern as you do, and I do not know what the pattern is that replicates 100%

This time, when I exported to Waveform Audio, as soon as I changed from my previous H.264 export to WAV, the Caption toggle was off and could not be toggled on, but the (greyed out) options could be displayed. When I attempted to replicate before, I could export captions with the WAV.

I exported as WAV. The I went back to Export (via Ctrl+M), and switched to H.264. I previously did this via the preset Adaptive high bit rate. The caption toggle was again unavailable and options greyed out.

I selected the preset and there was no change.

I clicked on Edit mode at the top, then on Export. The H.264 export had captions enabled and options were not greyed out.

Without doing any more exports, I went back and forth, changing between WAV and H.264 (either as preset or just selecting format H.264). Sometimes captions could be enabled; sometimes not.

The toggle goes on (or not) by clicking on the toggle button. The options below (greyed out or not) show or do not based on clicking on the word Captions or to the right of it.

I'll try to replicate in the Beta.

Edited to delete this since further testing demonstrated that it was not true: "If the captions can be enabled, then the options are not greyed out. If the captions cannot be enabled, the options are greyed out."

Here is a screenshot of the export window.  I'm currently running 24.0.0 (Builld 58) on Windows 11.  I have a scene that is using subtitles in the timeline.  I exported as a .wav file, went back to edit, returned to the Export option using the tabs at the top left corner and selected H.264 as the export.  You can see how the Captions export option is now greyed out and cannot be toggled.  If I return to "edit" and back to "export" then it works as intended, but it seems that something gets hung up there.

I just tested another method, and it looks like if I turn on captions when it is still selected as a .wav, and then select H.264, then it remains toggled on and I can export as usual.  Looks like the bug may only be if you have captions toggled off and change from a .wav to H.264, then it locks it as non functioning.

> I cannot implement the switch for subtitle export once I change the export to an .mp4. 

I'm not sure what you are doing. I am running PR 24.0.3 on Win 10. I can export a timeline as WAV. Then go back and export the timeline, change the export to .mp4, and sidecar and burn-in are options.

My timeline has not changed; it has captions for each export.

Screenshot? What version of PR are you running?
