Premiere Pro (Beta) v 24.6.0 BETA (Build 75) has lost undo

[NormanStormin]

With a brief bit of testing, the Undo in the above Beta seems to be completely missing. 

No changes that I make (interactive Transform of a clip in the program monitor, cutting a clip and changing the in out) result in an Undo queue.

Edit to add system:

Windows 10 Pro, 22H2 with updates performed

Kabylake i7-7700K

32GB RAM

OS and apps on SSD

Storage on Raid 5 HDD array

If I have the History panel open, then it will sometimes let you undo. But some changes (like cutting a clip in the timeline) don't seem to register in the History or undo queue. 

If I go to the Project bin, or another tab, then the Undo stops working.

It's still there in build 61

Just downloaded and tried 24.6 b75 on Win11 23H2 and I'm getting undo's as usual.

[Ann Bens]

So do I.

Beta 24.6.0.75. All 3 undo methods (Ctrl+Z, Edit -> Undo, and History panel) worked correctly for the operations I tested.

Some operations do not record each step, so be careful to report the specific steps that do not appear. But I like your method of leaving History open and observing.

Interesting... Is there any thing I could have done accidentally to turn off undos?

Although it is weird the inconsistency.

I shall try again after running a system integrity check etc....

[MyerPj]

Did you try it with a new project. Just create it and drop in a clip, make it one that has not been in PP, and then put a cut somewhere, see if it undos.

>Interesting... Is there any thing I could have done accidentally to turn off undos?

Although it is weird the inconsistency.

The inconsistency leans me toward resetting Workspace and then Preferences. In the Beta, I reset preferences with every build, so there is little downside. PR Weird Behavior = Reset Preferences.

I suppose you might have accidentally discovered the settings for number of history states. History Panel -> hamburger menu (3 lines) -> Settings. But the minimum appears to be 10, and it removes the earlier undos, not the new undos. So I doubt this is the cause. (Default appears to be 32, and it accepted 60 when I tried to see what max it had. But I don't want to find out!)

I set my history to 100.

[MyerPj]

I think Ann's got it. I set 100, good, then I tried 300, and the looked again and it was @ 100.

[NormanStormin]

I started PPro with the SHIFT key and reset preferences and all the caches.

I then created a new project imported one clip, and tried various edits. Razor, moving the clips etc. And they were all undoable. And appeared in the History panel,

I then imported the project I was working on. And tried the same things. And the problem came back. Most of the changes couldn't be undone. 

While I was doing this testing, suddenly the interface ground to a halt. In Task Manager PPro showed 20-30% CPU usage. 

Then I noticed on the top right a progress wheel. And when I clicked on it, it was showing a number of Auto COlor tasks being finished. BUt it was beavering away on a number of Auto Audio Tag tasks in the Progress window.

These were destroying the PPro usability. 

I had no idea that auto audio tagging was going to take place. It was clearly enabled by default, because I didn't enable it. 

It appears to be some kind of AI audio evaluation so it can tag audio clips with what kind they are. 

But it takes so much resources, that there is no way it should be enabled by default.

Again, Adobe has made a default that makes the user experience awful. 

I did notice at one point that when I was testing clip changes, it appeared to not be undoing the changes. But in that case, it appears that it was the auto audio tagging that was stopping the timeline from updating. 

In any case, I have no idea why importing the project suddenly destroys my undo abilities.

IN this case, if it is just that project, it doesn't matter, because that project is done with.

If this project was of any help to Adobe engineers, then I can supply that project (and clips if they really want.)

@NormanStormin,

Thanks for the details of the process for your troubleshooting.

I see now that there is a preferences setting at Edit -> Preferences -> Audio, for:

Auto-tag audio types in the timeline (default on)
Always override audio tags (default off).

This is in the Release 24.5.0 and in the Beta, I'm on 24.6.0.75.

This is not in Release 23.6.7, so new-ish.

But I can't imagine that simply tagging could use many resources. What are the tag "tasks" you are seeing? Is Enhance Speech on for any of these clips?

I wonder if the load is suppressing/delaying the undos?

@David Polk Any thoughts?

Stan

[NormanStormin]

The only information the tagging is that its an Auto Audio Tagging.

I haven't got enhance speech on any of the clips.

The load is only around 30% total CPU capability. So its not even saturating my CPU.

The Auto Tagging seems to be blocking the internal PPro processing. 

I can't see what threads are happening with the default windows tools. I'll try to find a more sophisticated tool that may report what threads the processes are doing.

It sure seems like PPro is only using very limited threads and it gets blocked. But that's just speculation.
