P: Alt+ Scroll zoom behaves different on v24.4.0

[Jeremy22269921hcpn]

Updated to latest version 24.4.0 and the Alt+ scroll zoom behaves different. It zooms to a totally different timeline area than the usual mouse pointer/playhead. Any workarounds?

[Ann Bens]

I can reproduce this.

One of the first things I noticed, and I'm glad I'm not the only one.

It used to zoom into whatever my mouse cursor was pointing at, but now it's not working. I'm on Windows (11) and my DPI scale is set to 200%. It seems to work correctly when scaling is set to 100%, but this is not a viable workaround.

This was not an issue pre-24.4

@Jeremy22269921hcpn @Ann Bens are you also using Windows with DPI scaling enabled?

[Jeremy22269921hcpn]

Yes, my main monitor (4k) is set to 200% and second monitor (hd) set to 100% recommended. And yes, it was working normally prior to this latest update.

[Ann Bens]

IMO this has nothing to do with windows scaling.

[Trent Happel]

Alt-zoom issue with some or all Display scale settings has been reproduced and is under investigation. Thank you for your reports. They have been helpful!

What's happening (bug): when I try to zoom in/out the timeline using ALT - mouse scroll wheel, the zoom center moves depending of the mouse arrow position. Timeline playhead moves around when zooming and even disappears from the zoomed view. This behavior makes no sense.  (See attached video)

What should be happening: the zoom center should be the playhead and It should always stay in the center of the zoomed view (unless timeline is max zoomed out).  When I use the timeline panel handlers to zoom, Premiere does it correctly. (See attached video)

I updated Premiere today. Last version was working OK.

Premiere Pro 24.4.0 / Win11 22631.3447 / Ryzen 3950X / 64GB RAM, 3080 12GB

Same here, any solution for this? Drives me crazy...

[Stan Jones]

See this report:

https://community.adobe.com/t5/premiere-pro-bugs/alt-scroll-zoom-behaves-different-on-v24-4-0/idc-p/...

The problem behavior was reported in Release 24.4.0 and the current Beta versions.

Note that the roll-out of 24.4.0 has been halted:

https://community.adobe.com/t5/premiere-pro-discussions/release-of-premiere-pro-and-media-encoder-v2...

But the behavior you describe appears to be the regular behavior: When you use the timeline panel handlers, there is no mouse cursor position (marked a white line above the timeline). That adjustment must use the playhead position. When there is a mouse indicator, that is used by the Alt+Zoom.

I checked in PR 2022, and I see the same behavior.

What appears different in the report about 2024.4 and current Betas is that NEITHER the playhead nor the mouse cursor position are used. And it does not appear to be related to Windows scaling. As a workaround, I found that placing the mouse position to the right of the playhead by some amount resulted in it zooming around the playhead.

@Trent Happel This is confusing. Can you confirm the intended behavior for Alt+Zoom?

Stan

[Trent Happel]

Alt/Opt + mouse wheel zoom in the Timeline should zoom based on the cursor location.

[Alberto279400979a2h]

It should, but it's not. Bug seems to affect UHD monitors with scaling applied (mine is 150%). When i changed it back to 100% (and having all the interface extemelly small) everything worked as intended.

Thanks for reading me.

[Trent Happel]

Ann, are you able to reproduce this issue with Windows Display scaling at all Display scale sizes?

[Ann Bens]

I dont know what changed but cannot reproduce anymore for 24.3 (dont have 24.4 yet) and the beta build 42.

Might be a windows update I had yesterday.

[Trent Happel]

No worries. Thanks for the quick update, Ann!

[Andy36793604q399]

Did you find a fix for this? Currently have the same issue and it's infuriating haha. Best!

[Jeremy22269921hcpn]

I have read in other forums that reverting to previous windows versio with many issues. But I haven't tried that myself. Hopefully there's a new PP update soon!

[Stan Jones]

@Trent Happel,

Past discussions of Scaling issues have been complicated by the 2 scaling options in Windows. My standard setup is Windows scaling set to 150% (of the % options, 150% says "recommended") and "Advanced scaling settings" NOT set. The advanced option prompt says "Enter a custom scaling size between 100% to 500% (not recommended)

It is the Advanced scaling that has been a problem in the past.

I tested with the "regular" scaling set to 100% and 150%, and with Release 24.3 (no 24.4 for me yet), Beta 24.5.0.16 and, after update, Beta 24.5.0.43. I see no differences based on scaling.

The behavior I see in 24.3 is that the zoom is around the mouse cursor position, not the CTI position/frame on screen. It appears to zoom around the CTI if the mouse cursor position is over the CTI. In Beta 24.5.0.16 and Beta 24.5.0.43, it only zooms around the CTI if the mouse cursor position is some distance TO THE RIGHT of the CTI. But it is not simply zooming around the mouse cursor position, nor the CTI.

I did get a Windows update in the last few days:

Windows 10 Pro
Version 22H2
OS build 19045.4412
Experience Windows Feature Experience Pack 1000.19056.1000.0

[Trent Happel]

Ahhh, good info, Stan. In my case, I was setting under System > Display > Scale and 100% was recommended. I will update my prior responses and also pass this on to the team.

[Trent Happel]

Oh, and my system is Windows 11 Enterprise ver. 22H2

[Ann Bens]

@Trent Happel 

Cannot reproduce in 24.3 both with 100 and 150 % (recommended).

But on the other hand the beta (build 48) is misbehave both 100 and 150%.

[benoit32103912r1lt]

how can i desable this zoom over source or program window, it is so annoying, espacialy with magic mouse, either let us zoom only when mouse in over the video scrren (and not next to) better is to have the choice to zoom only with alt+scroll or the possibility to lock the zoom factor. Before i coult scroll the video when the mouse was over the video or next to without to point just on th time section. So please let change this 

Tanks

[nickp86660807]

This is also hapoening to me. Can't zoom in where playhead is placed with alt click but can use my asus dial and it zooms in correctly. Please let me know if this gets fixed it's so annoying to deal with

[Jason Nolan Wedding Films]

Same issue here on 4K monitor whether with 150 scaling or 100 which is unusable anyway. Only happens with scroll wheel, zoom works normally with the scroll bar. Rolling back for now. 

[Kacper286898925511]

I got same error :<

[VJ SPAZZ]

This is totally broken, it's extremely frustrating.
