I am editing a project for a client and I am stuck, and there is a deadline looming. My source material is XAVC Intra. When I attempt to bring in to Premiere either through the Media Browser or through File>Import, the result is an audio-only clip, no video. I also tried to bring the footage into Media Encoder and After Effects, with same results. After reading about other issues with XAVC format in Premiere, I downloaded Premiere Beta, but had simiular results. Thinking that perhaps Black Magic Desktop Video was somehow interfering, I uninstalled it but still had the same issue. I took the media to an edit facility also running Premeire 15.4.1, and had the same result. I can open the file just fine in QuickTime Player v10.5 and in Final Cut Pro 10.5.4, but not in Premiere 15.4.1. If I don't get this resolved today (10/5/21), tomorrow morning I will be forced to transcode all of the footage in QuickTime to H.264 (removing timecode, lowering resolution and minimizing color imformation) and eye-match the edits to the rough cut. I appreciate any help in this issue.

I was doing a deeper dive to troubleshoot the XML export issues outlined in a previous bug report (https://adobe-video.uservoice.com/forums/911233-premiere-pro/suggestions/43998075-bug-audio-exported-from-premiere-pro-2021-via-fin) and discovered another bug.

Theoretically you can use a workaround to fix the export bug, if you have a 23.976033fps file you can replace footage with a 24fps file of the same content, make a new sequence off the 24fps file, and then copy your edits over to it. This allows you to export an xml that works when you import it back into adobe... mostly.

I say mostly because there's another bug that pops up, I believe due to the way different versions of Premiere Pro round the framerates. Based on the math of the ppro ticks it looks like 2019 is rounding framerates to 3 digits after the decimal, and 2021 uses 6 digits. This results in different ppro tick values for the exact same cut in different versions of Adobe.

This in itself isn't an issue, but the way it's interpreted causes a bug in xml imports. Premiere doesn't really respect the -1 in start/end xml tags which indicate a transition is attached to one end of a clip.

simple example:
Clip 1
In: 0
Out: 100
Start:0
End:100

Clip 2
In: 100
Out: 200
Start:100
End:200

Apply a 1 second Constant Power transition (24fps) and these values become
Clip 1
In: 0
Out: 112
Start:0
End:-1

Clip 2
In: 88
Out: 200
Start:-1
End:200

When a transition is applied to a clip, the in/out values change by (for example) half the length of the Constant Power transition.

So if you have an audio transition that's fully shifted to the left, the pproticks being just slightly off between versions can cause it to ONLY apply the transition to the left of the two clips. Because the clip lengths have been changed in expectation of a transition being applied to them, you end up with audio that's desynced from the video. For example if the transition was only applied to the left clip, then the audio in the right clip would start roughly 12 frames too early, because it was expecting the additional 12 frames of audio to be used/encapsulated by the transition.

There should be more protection/bug checking around the -1 start/end values so that transitions that are a few pproticks off from where they should be still generate their transition correctly rather than being detached from one of the two clips. In the previously outlined export bug for instance, you could have erroneous transition values that put transitions in the middle of clips, 30 seconds away from any cuts that might have needed a transition. Premiere pro should detect and warn the user of transitions it can't fix, rather than happily placing broken transitions on the timeline.

Thanks for the new speech-to-text feature! I'd also really love to see the option for synching the already existing transcript (from the .txt file, for example) with the video.

Most of the time, I already have the text of what is said in the video, so using speech-to-text and correct it where needed is kind of not the most rational way of doing things. If you introduce this function, that'd be a life-changer for me, so much time would be saved.

When I tried to use "Import transcript" feature, it only allows .prtranscript files, but I have plain text.

Thank you! Looking forward to your response and hopefully that feature too. I actually bought Premiere Pro with the primary goal to make captions for my videos
