AE has the Snapshot button, which lets you hold on it to switch between what's currently visible to the snapshot you took

Right now, the button will simply show you the snapshot and that's it

I think it'd be cool, if by holding the button and dragging your mouse left-right, you could overlay the snapshot with 0 to 100% opacity

UI was working fine and smooth using 1920x1080, but since the day I work with a 4k monitor it is terribly slow. I had to tweak some windows settings to get better performance, but this makes the UI look blurry... so either an awfully slow UI or a blurry UI...

The reshape tool would become way more helpful with digital beauty work if AE had a way to parent Masks to a Null object that received tracking data from Mocha.

One of the bigger frustrations I have with AE comes up when I open a project created by someone else, and the AE UI converts to THAT person's layout. I can think of 0 instances in which that would be of any use.

I know I can go to Window->Workspace and call my saved layout back up, but why should I have to? Please change this behavior.

The window menu will NOT scroll up or down using the scroll wheel. I'm guessing this is a bug.

Clicking the small arrows in the top and bottom in the ONLY way I have found to advance the menu, and I can only scroll one item at a time via clicking. This is extremely slow.

I assumed this would be fixed in the latest update, but I was wrong. As of 17.0.2 (build 26), it's still there.

Certain custom keyboard shortcuts cannot be customized. For example, I want to remap the Selection tool to the "A" key. After Effects does not allow this to happen.

I am able to make this change in Premiere Pro and Photoshop, and would appreciate if the same can be done in After Effects by removing these restrictions.

フォントをキーボードの十字キーで移動して選んでいるとき10個目ぐらいからエラーが起きてソフト自体が「応答していません」と表示されます。
十字キーで移動でき、フォントを一個ずつ表示されるのは本当に助かってます！
あとはエラーが起きないようにしていただけると助かります！
よろしくお願いします！

This would be a great feature but it doesn't work very well! Advanced layers don't work properly, some types of easing don't display correctly, and nested/masked layers don't display correctly (see attached screenshot).

Please implement it properly!

I'd love for AE to hook into the "in progress" API of its taskbar icon, like Chrome does with its downloads, so I can see the progress of my render without having to click back into AE!

6 hours for a 5 min 1080p file on a 24 core workstation system is unacceptable for a program designed to be professional.

Just select the folder where AE should load the plugins and scripts from.
Like it is in Cinema 4D R21 or like it is handled with extensions.

After a while, the composition window just turns black and shows no graphics. The borders and masks are shown though, but no visuals. And when pressing spacebar to RAM preview, it doesn't play. Restart helps, but the issue keeps returning so I need to restart all the time. Happens on larger project files.

Hello,

In the After Effects composition settings, it is not possible to have an alpha background. Example in attachment.
I would like to have this feature to launch a preview with alpha.
An alpha preview, would play the alpha on a video device that works in compositing. Example in attachment.

thanks you for attention.

In the new and the classic Mac Pro the fastest drive possible is a NVME SSD or a RAID of multiple SSDs that is connected via a PCI card such as the "Sonnet M.2 4x4 PCIe Card" or the equivalent from HighPoint.
The problem is that these volumes get recognized as external, removable drives and After Effects will not except them as cache location.
So it's nonsense to restrict the drive selection. Please remove that function and let the user choose. If someone stores his cache on a slow thumb drive it's his own fault.

Bug report. When opening projects created in previous versions and the re-saved in 17.0.1, receive error message "After Effects Error: missing data in file. (33::4)". Only solution is to revert to 17.0.0.

This latests update wipes out all the plugins that I had in After Effects, and Now it wont read the video copilot vc color vibrance plugin even after it has been deleted and reinstalled.

Since the 2020 update, when you try to import several JPEG images into the project, some of them are the same image, even if they keep their correct names.
For example I export images called "01", "02", "03" and "04". When I check them in the timeline, "02", "03" are the same images (they have the same visual content) but with different names. The problem doesn't happen when you export the same images but in PNG instead of JPEG.
