Currently (in Ae version 15.1.0) it is impossible to assign a hotkey combination that contains Esc button.
There is no Escape key in left upper corner in displayed keyboard model, so you cannot drag some action to button (or button to some action).
When you try to create a new key binding and press Esc, then this Keyboard Shortcuts window will just close.

This bug has an easy workaround: Press "ctrl + alt + ;" to open settings, then press Reveal Preferences in Explorer, then go to aeks folder and edit Custom.txt manually.

To solve this bug Adobe can add Esc button to keyboard model (for every layout) or do not close window at esc button. The same behavior is in Pr.

I had a major issue opening up an older project today. I went through multiple reinstalls, Adobe CC Cleaner tool, a round with Adobe support because my apps were suddenly not working even after installing (that's another long story) etc. without any remedy before coming to this resolution. A full 5 hours spent on this issue.

At first, I thought it might be Premiere linked comps so I copied the AE project over to my desktop and unmounted the original drive to force a disconnect between the project and any source files. I then opened the AE project without any issue so I re-saved under a new name and deleted all 'Dynamic Linked' Premiere comps that appeared in the project. Re-mounted the drive and launched the new version of the project but it wouldn't open (curiously, it used to get to 53% before hanging with the "1 Sec remaining' message but now it would hang before the progress window could finish drawing itself - I had just a white rectangle where the window was supposed to be). I force quit After Effects (only way to close it with the troublesome project), unmounted the source drive again and then opened the 'disconnected' project.

This time, I chose the comp that I actually need to make changes to and consolidated it (under dependancies>collect files). Then I closed down AE (for kicks and giggles), restarted it and opened the consolidated project with the source drive still unmounted. At this point, the consolidated project consists of just 1 piece of Red footage, another quicktime file in h.264 codec, 1 master composition, 1 nested composition for mocha tracking on the Red footage, an Illustrator doc imported as a composition and a handful of solids.

First, I remounted the source drive and tried to reload footage (right click>reload footage). This promptly caused AE to hang. Yay. Went through the force quitting/unmounting/reopen process again. This time, I tried just importing the clips in question and got sent down a rabbit hole as the very first clip I tried to bring in hung AE. After going around in circles and then trying to take that same clip into Media Encoder, I had an 'Ah-ha' moment. This clip was suffering from the issue that's been going around in various AE discussion circles since the last update (re: dropped support of 'legacy' codecs). Although it is supposedly under the supported codecs banner (again, this clip is in h264 codec), for whatever reason the Adobe products do not like it. How do I know? Well, trying to bring that same clip into AME in order to create a fresh test one caused it to crash immediately - I mean, as soon as I dropped the clip into the AME window, AME hard crashed. This was repeatable with this clip but couldn't be replicated with other random h264 clips I tried.

So, I took the clip in question and opened it in my still-somehow-laying-around QT7 application and exported as, well, another mp4 file. After re-opening the AE project, importing the new mp4 clip, replacing any instances of it in compositions (option drag from project window to selected/highlighted clip in comp to replace in place) and then reloading the rest of the footage, everything appears to be ok.

My After Effects and AME options went from around 50 codecs that I need access to for both import and export to MAYBE 10?? And the ones that remain are the ones o never ever ever ever use.

What kind of decision is this?? Eliminate MODERN AND HEAVILY USED codecs like HAP? NDI?

This is ridiculous!!

Please tell me there's a fix coming... I'm very unhappy paying for what is basically a useless subscription at this point...

Please!!! A Fix?? Is it coming??

I don't care that Apple stopped supporting QuickTime... There are still new and great codecs using the platform!

Please... I need to know if you're going to fix my After Effects or if I need to cancel my account because right now I CAN'T USE THE SOFTWARE I'M PAYING FOR.

It would be great if the toolbar could be displayed vertically like in Illustrator and Photoshop, and dockable to the sides of the AE window.
On top of that, it would be great to be able to edit what is shown in the toolbar, also like in AI and PS.
For example, I never use the paint tools so I could hide them, but would like the Convert Vertex tool to be always displayed without having to click and hold on the pen icon.
Having the ability to create new toolbars with a custom selection of tools would be handy too.
The AE extension KBar is a great example of how a flexible, editable toolbar can be really useful.

The TIFF file format contains the ExtraSamples tag (338) which can be used to give a description of extra components. This field can be used to specify inside the file if it contains premultiplied or straight data.
When AE exports a TIFF sequence it just leaves this field as UNSPECIFIED. This causes other software (and AE itself) to be unable to know if the data is premultiplied or straight.
Similarly, when a composition is created from a TIFF file AE does not seem to read this field and thus it's guessing wrong as to what kind of contents is in that file.

New Project Template is a great addition for getting your project off on the right track quickly. But if you've taken the time to setup a template for yourself, you've probably noticed that you routinely have to tell AFX that you don't want to "save" when you open something else.

When you start up AFX or close a project, the template loads. But then you open an existing project and you're prompted to "Save Changes?" AFX should be able to tell that this is an unchanged template and not prompt you to save.

In a production environment, I'm opening existing projects many times a day and this extra step is a speed bump that isn't necessary. So much so that I don't know if the template is worth it as it is now.
