The full error messages reads as follows -
"The Motion Graphics Template has corrupt metadata and cannot be installed".

Is it possible to refresh the metadata in AE?

I have about 200 props in the EGP and will rather not have to rebuild the entire EGP again; especially when there's possibility of another breakdown.

Restarting AE didn't help. Importing the AEP into a blank AEP didn't help. Renaming the Comp didn't help.

A very strong possibility of this metadata mess seems to manifests itself with props in the EGP disappearing. They're still there since trying to re-populate the EGP with the missing prop throws an error stating the prop is already in the EGP. With such issues, closing and re-opening the Comp or EGP helps. However, user should have the ability to refresh/clean the metadata or something that helps to clean up the mess that starts when props disappear from the EGP.

Any assistance will be greatly appreciated.

FIX THE ******* RENDER PREVIEW

when did this software became so bad? I used after effects professionally for more than 15 years and oh my god how terrible things are now. I can't even render preview in real time anymore. I remember back in the day when I would render preview something, I would wait for the cache fill up how many frames it had room for and bam, here is your smooth, real time preview. Now jesus christ I can't preview anything substantial because things keeps slowing down and a stupid warning comes up "not real time" oh really? thanks for letting me know, like the audio pitch going down and jagged frame rate weren't enough to show me that. listen, i've been paying for this software for years and the frustration is unbearable. I think is time to look for other options available. I've been reading "we are trying to fix it" for too many years now.

It is common to animate the scale of an object along one axis (imagine a bar graph animating upward). Of course you do this by unlinking the X and Y scale proportions and increase the Y scale over time. And if you want the animation to be more dynamic you will use the graph editor. This is easily done with the Value graph. However, trying to do this with the Speed graph is very difficult. This is because the X influence is overtop the Y influence - and when you graph the handles of the keyframe in the Speed graph editor it automatically selects the X (represented by a red line), not the Y (represented by a green line). The only way to adjust the Y influence is to "move" the X out of the way to get to the handles that control the Y influence. I suggest adding an option that will allow you to independently control the influence of X and Y (or at least be able choose which scale -X or Y- you want to adjust inside the Speed graph).

I've attached a couple example images showing what is necessary to do in order to get to the Y (green) influence. I'd rather leave X alone (no curve).

AE 2021 - The Layer Panel no longer displayers Motion Path handles for Effects or Motion Tracking. This is a major hindrance when animating and tweaking Effects paths or analysing Motion Tracking problems. See attached comparison from AE 2020 and AE 2021. I have also tested this in AE Beta and the problem persists.
I am trying to attach jpg examples unsuccessfully.
Here is a more detailed description:
AE 2020 >Layers panel displays >Effects motion paths with editable bezier handles; and for >Tracking Motion paths
AE 2021 Using the same settings, the >Layers panel does not display any handles for >Effects motion paths or >Tracking Motion paths
AE Beta - same as 2021

Know there's been a lot of talk about the updated view options. TBH, this new setup sucks.

I want my 2 views vertical back! I often am comping 16x9 animations. I need one viewer for my active camera, and a 2nd for my top view. Since I can no longer determine the layout of these 2 panels, I'm stuck with the horizontal view. This layout isn't ideal if you're working with a widescreen comp. It means your footage is suuuuper tiny in frame.

Don't eliminate the 2 view vertical though- it's useful for doing 9x16 comps. Just give us our options back please!

Lastly, a customizable toolbar would be very helpful. I keep having to rearrange my panels because the "view" and "camera" options are so far to the right hand side of the panel that they get clipped. See attached image.

If you can't give us an editable toolbar, at very least switch the order of the buttons I circled and the camera/view options. I guarantee those are used much more frequently than the draft 3d or classic 3d options.

AE is like a Build-a-Bear. You start with the default, and then you dress it up. Plug-ins are essential to After Effects. As essential as pants on a Build-a-Bear.

Media Replacement is a great new feature, especially for MOGRTs. But you can't export a Media Replacement MOGRT that uses plug-ins anywhere in the After Effects project. I understand performance may be bad, but a warning that the MOGRT will be slow is preferable to never being able to combine MR and plug-ins. This is a hindrance for professional pipelines considering adopting a MOGRT workflow for motion graphics.

Please reconsider enabling plug-ins and MR to cohabitate inside MOGRTs for Media Replacement v2.

I am using the "Responsive Design - Time" functionality for the first time in After Effects and unless I'm misunderstanding the functionality, trimming, rather than time stretching, appears to be broken right now.

I have a composition that contains a video clip that is replaceable via the essential graphics panel. The composition has a protected intro and outro. In the nested composition, I need to be able to extend the composition length via trimming, rather than stretching, in order to preserve the speed of the replaceable video clip contained within it.

According to the help page for the responsive design - time feature, "To trim the in or out point of the layer instead of time-stretching, hold the Option (macOS) or Alt (Windows) key and drag the in and out points."

But when I attempt to lengthen the composition while holding alt, After Effects does not let me. Oddly I can adjust the positions and lengths of the protected portions of the composition by holding alt and dragging them, but I cannot actually figure out if this is affecting anything.

Is this a bug, or am I misunderstanding the functionality here?

Thanks!
