Maya 2024.1 Timeline Hang when Shifting Keyframes

[natedgreat3]

EDIT:  Autodesk has advised me this bug has been patched and will be released in a future version of Maya.

On latest Maya 2024.1, the new timeline, while it looks nice, has terrible performance for me when trying to work with dense keyframes over many objects/controllers. 

I have some motion capture data on a regular biped skeleton, so keyframes every frame across 100 frames and about 90 bones.  No other rigging or scene information, very vanilla stuff.  Doing basic manipulations like sliding, scaling keys in the old Maya 2023 timeline is near-instantaneous.  On the same scene file in Maya 2024, the new timeline will hang with 1 CPU thread maxed out for *MINUTES* before it does the requested operation.  And it will do this every time I want to do these operations.  This makes it completely unusable for me, and I've immediately downgraded back to Maya 2023. 

This problem seems to scale based on the number of keyframes and controllers selected.  On small numbers it seems okay, but quickly becomes unusable the more you select, in a way that the old timeline was able to easily handle but this new timeline cannot.  

Happy to provide scene files and YouTube videos upon request.  

Has anyone else experienced this problem?

Likewise, same here. Very very long and heavy hang, It happens when I select more then 2 rig controllers and more then 2 keys ( for example I'd drag-select 20 keys )  and try to move keys on timeline.  What d hell ?

Hello everyone,
We have the same problem on our side, and it's very problematic, but I saw the EDIT that was made.

Good news for the next patch, do you have a release date for version 2024.2?

Sincerely

I'm on Maya 2024.2 and it's still happening.  Sometimes freezing seemingly forever and after 10 minutes I just end task.   SUUPER annoying and makes me afraid of drag selecting keys.   It usually freezes before I even attempt to do anything else, just select is enough to freeze.

Hi,

Thanks for reporting this issue.  Please provide more details to help us reproduce it.  What OS?  Can you repro with/without cached playback enabled? What are you animating?  Does it always happen, or only when many keys are displayed? Does it happen with a very basic scene (some keys created on a cube)? If you can share a file, or post a repro video, this would be very helpful.

Regards,

Kelly

Yes, it happens with anything that has keyframes you want to select and drag in the timeline.  Even a simple cube, although with a cube and short animation the hang will be very short.  It seems like the more keyframes you have or the more controls you select, the longer is the freeze.   In my case I'm animating Character rigged with Advanced Skeleton.   I never have caching on since the rig is fast enough without it.   Also yes, keys are displayed, since I'm selecting them in the timeline so I can drag them.

And again, it seems to only happen the very first time you try it.  If the freeze goes away and maya comes back to life, the next time the freeze doesn't happen during that session.

Is there an ETA for a fix for this?

[vincleombruno]

Happening here too (Maya 2024.2, Win10Pro). Simple scene, with two joints and a control driving it through a parentConstraint.

This is happening with scenes of all range of complexity.

Please provide a fix ASAP.

Same here.  Same Maya 2424.4 and it's still happening.    Our pipeline isn't ready to upgrade to 2025 yet (not sure if it's an issue there too or not)

2024.2 here and this is insanely frustrating.

Same here, maya hangs indefinitely when selecting keys on the timeline. PLEASE fix this!
