Bug Reports

When selecting a large number of keyframes in the Timeline using marquee selection, the After Effects UI becomes progressively slower as the number of selected keyframes increases.This is especially noticeable when repeatedly adding more keyframes to the current selection.Steps to reproduce Create a composition with a large number of keyframes across one or more properties/layers. In the Timeline, use marquee selection to select some of the keyframes. Keep adding more keyframes to the selection using additional marquee selections. Observe the Timeline UI responsiveness as the number of selected keyframes increases. Actual resultThe Timeline gradually becomes less responsive as more keyframes are selected.In my case, the slowdown starts becoming clearly noticeable at around 100 selected keyframes. As the selection grows further, marquee selection and other Timeline interactions become increasingly sluggish.The important point is that this does not appear to be caused simply by hav

After Effects version 25.6.0MacOS 26.1 While using After Effects, and only After Effects, I find that every few keystrokes is ignored by the program. It happens everywhere, when renaming layers, when typing in timecode, when typing text into a text box. Goes without saying the expected behavior is that... that doesn't happen. Here's an example best I could show it with screencapturing software. You can see me start typing and I enabled keystrokes and you can see clearly that I typed several characters towards the end and it completely ignored those characters that I typed. This isn't unique to text boxes, it happens everywhere in the program. When typing in fonts, when renaming folders in the project panel, when typing in timecode, renaming layers in the timeline, you name it, this is happening all the time. Video on Dropbox 

Not sure if this is to be classified as a bug - but it is weird behaviour driving me nuts. When After Effects auto saves, it also jumps to the foreground.So if I am doing something in another app, AE will hide that app and jump to the front if it's time to auto save.Sometimes I am "lucky" and it will just bounce the Dock icon. (Which also interupts my very important web surfing etc) AE 25.1 on Mac OS 15.3 (but it's been like this forever)

Hi everyone, ever since I updated AE to version 26.0.0 I have experienced render times as much as ten times slower than it used to be in version 25.x.x. For now, I have rolled back installation to a 25 version, but I would very much like to keep up with the versions, including all new features.I read somewhere that I'm not the only one bumping into this problem.What can I do to solve it? To be clear: I can create a project in v 2026 and it renders terribly slow; when I save it as 25.x version and then switch to AE v2025 everything works at proper render times.Will there be an update for v 2026 that solves this problem?

Manually changing the position of a guideline now requires an additional step.  Steps to Reproduce:Add a guideline to a composition. Right click it, and select “Edit Guide”.In the old Edit Guide dialog box, I used to be able to press the Delete key one time, type the new number, press Enter, and the guideline would move without ever having to click the box. Now, I have to highlight the FULL text in the text box and delete it, then type the new number.  

I've updated After Effects to version 25.0.1, and now the color picker/eyedropper tool isn't picking the correct colors for shapes, text, etc. It’s close, but the hex codes don’t match exactly.I'm selecting colors from the Library window within After Effects.When I change the setting in After Effects > Preferences > General > system color picker, it does pick the correct color. However, I’d prefer not to use the system color picker—I want to use the default one.This issue didn’t occur in the previous 2024 version of After Effects, where everything worked perfectly with the same project color settings and color management.Has anyone else experienced this or found a solution?

it should work like this: (function () {    app.beginUndoGroup("Separate Dimensions + Preserve Easing");    try {        var comp = app.project.activeItem;        if (!(comp instanceof CompItem)) {            throw new Error("Keine aktive Komposition.");        }        // ------------------------------------------------------------        // Helpers        // ------------------------------------------------------------        function vectorLength(v) {            var sum = 0;            for (var i = 0; i < v.length; i++) {                sum += v[i] * v[i];            }            return Math.sqrt(sum);        }        function normalize(v) {            var len = vectorLength(v);            var result = [];            if (len < 0.0000001) {                for (var i = 0; i < v.length; i++) {                    result.push(0);                }                return result;            }            for (var j = 0; j < v.length; j++) {                result.push(v[j] / len); 

Title: After Effects Composition panel turns completely black when preview playback stops — RTX 5080 / Ryzen 9 9950X / Windows 11Issue descriptionThe Composition panel turns completely black whenever preview playback stops. During playback, the composition displays normally. As soon as playback stops, the entire Composition panel becomes black and remains black.Steps to reproduce Launch After Effects 2025 or After Effects 2026. Create a new composition. Add a solid layer. Start preview playback using the Spacebar or numpad 0. Stop playback using either method. Expected resultThe Composition panel should continue displaying the current frame after playback stops.Actual resultThe entire Composition panel turns black. Scrubbing to another frame and switching between RGB and Alpha channels do not restore the image.Scope and environment Operating system: Windows 11 CPU: AMD Ryzen 9 9950X GPU: NVIDIA GeForce RTX 5080 Affected applications: After Effects 2025 and 2026 Reproduc

I have a composition that I need to render as various different clips. The background is a yellow color, and on top of it I add an element as the timeline progresses. The only color in the composition comes from the background, which does not change through the timeline. I set the work area to the clip I need and send it to the renderer. I then change the settings from “work area” to “custom" so that the start and end point of the clip are kept in the renderer I repeat this for each on of the 14 clips I need I start the renderer. The first two clips rendered with the correct color, but form them on, the rest render with a duller color.I can’t figure out why this is happening. This are my specifications:AE Version 26.5.0 build 89Windows 11GPU: Nvidia GeForce 32.0.16.1088Thanks for the help.

In Preview, play from current time plays from the first uncached frame, rather than from the cti.

how do i fix this!

i brought 4k R3d footage into adobe after effects 2026. and it looked like the color profile was all wrong. so i Right clicked it, chose interpret footage, main, click the more options button at very bottom. Scroll all the way down to output transform section, changed color space to redWideGamutRGBm and change gamme curve to Log 3G10.and my after effects timeline is only 24 frames long. i applied colorista to the clip. then i applied keylight to the r3d footage and sample the green but the background doesnt disappear which means the image is frozen. and im looking at it with quarter resolution. then i hit save and tried to quit and its locked up and not quitting so i had to force quit and come back in. and now i can see the green screen is knocked out so i put a stock clip behind my green screen subject but then turned the layer off and even though its off its stil showing me this stock footage background which means the image isnt updating in AE. its like its locked up but its not. it

When previews are started from the chi, the audio is sometimes starting from the beginning of the comp, while video is starting from the cti..The preview system seems kind of broken - lots of issues.

Issue - When working in a composition larger than 10,000px horizontal, guides can no longer be placed at positions further than 10,000 pixels when using the “Edit Guide...” dialog. The dialog accepts values larger than 10,000 in the text box, but will always snap back to 10,000 after clicking “ok”.Steps to Reproduce:Create a comp with a horizontal resolution larger than 10,000 pixels (for example, 11,000) This step doesn’t seem to be 100% necessary, the issue occurs when placing a guide further than 10,000px even with a comp size smaller than 10,000px wide. Turn on rulers and drag a vertical guide out from the ruler. Right click the guide and click “Edit Guide...” to open the dialog box. Edit the “position” value to be a number larger than 10,000 pixels. Click “OK” Observe the guide snapping to the 10,000px position, right click the guide again to see that it is at 10,000px instead of the position entered.Expected Result - Guide should be placed at the position value entered in the “E

ISSUEWhen Layer > Scene Edit Detection is run with "Split Layer at Scene Edit" and "Create Pre-comps" enabled, and the project's Time Display Style > Footage Start Time is set to "00:00:00:00", the footage layer inside every pre-comp except the first one gets wrong In/Out points.The In point is placed at the very start of the layer instead of at the start of the detected shot. The Out point is placed at In + shot duration. The trimmed range therefore covers the wrong part of the source.The rendering engine ignores these in and out points. Sequence rendering continues beyond its out point !!!With Footage Start Time set to "Use Media Source", the same steps give correct results.STEPS TO REPRODUCE1. Project Settings > Time Display Style: select Timecode and set Footage Start Time to (00:00:00:000).2. Import a video that contains several hard cuts.3. Create a composition from the footage4. Select the footage layer and choose Layer > Scene Edit Detection.5. Enable "Split Layer a

Issue:After Effects 2023 (23.6.9.2) crashes immediately at startup, before any project is opened. The crash occurs in the plug-in loading phase (PLUG_Search / BirthPlugins) when the shared Camera Raw plug-in (18.7.0.2743) is loaded. AE 2021 (18.4.6.2) and AE 2022 (22.6.0.3) show the same startup crash. AE 2020, AE 2025 and AE Beta on the same PC start normally. AE 2024 is not installed. Renaming Camera Raw.8bi lets AE 2023 start normally. I still use AE 2023 for work, so I would like to know if there is a proper fix.Context:AE 2023 worked normally before Oct 10, 2026 (I used it the day before). On Oct 10 I updated, via Creative Cloud, the beta builds of Photoshop, Illustrator, Premiere Pro and After Effects, plus Photoshop 2025 and Illustrator 2025. The Creative Cloud update history shows Camera Raw was updated to 18.7 on the same day.Test results (launch only, no project opened):With Camera Raw.8bi in place (Camera Raw 18.7.0.2743):- AE 2020: starts- AE 2021: crashes at startup- AE 20

Just to test. I went to 2 million value and also went negative -23.000 value. Not an Ae expert but I’m sure this is not normal. There is no limiter to any of these values when they are supposed stay between 0-255. Exact same bug exists on Premiere as well. System info    Application: After Effects v26.5.0 (build 89)    OS: Windows v10.0.26200, RAM: 31.82 GB GB, CPUs (logical): 24     GPU: Rtx 3060 Ti  Nvidia Studio Driver ver. 617.42

adding Lebel group in effects control panel is welcome feature but we lost Effect Matte indicator icon in Effects Control panel after the update. is there way to bring it back?thanks,t system info:MacStudio M2 UltraOS 15.7.9AE 26.5.0 

there is glitch in Refine Edge Matte with Chatter reduction Smoother selected.it’s only happens if the precomp layer has blank frames. I'm guessing that Smoother option look for before and after frame for Chatter reduction. there is no issue if the roto brush is applied at the 1st frame or apply directly to footage that trimmed but frames exist,solution now is trim the precomp to footage length, add duplicate frame at frame before, extend head frames if you have.thanks,tsystem info:MacStudio M2 UltraOS 15.7.9AE 26.5.0 

Selecting mask path on solid layer and then hitting ctrl + t to transform whilst dragging the transform box edges the mode of the mask randomly changes or cycles through. It then remains on whichever random mode it was on when releasing the mouse. This occurs both with mouse and pen tablet. Video attached. AE version 26.5.0

when i add lumetri to a .heic file in adobe after effects 2025, it stretches the whole image. i’ve encountered this a few times in the past. Happy to upload a picture to show you, but i cannot post it to a public forum. I then took a professional picture downloaded from Getty images and applied lumetri to it, and it too became stretched. (but if i delete lumetri and try colorista, it doesnt stretch the photos). Lumetri should not be warping/stretching the photo.AE version 25.6.6 (build 4), mac os Golden Gate 27.0.1.
