There is a glitch that is especially noticeable with the TRANSFORM effect in AE CC 2020. Easily reproducible:
New composition
New solid
Add transform effect
Add rotation keyframe
Add second rotation keyframe further down (1x cycle)
Render

There are random black glitches on rotation. This does not happen with the native transform (non-effect version).

Does not appear to be reproducible with RX580 in 10.14.6.

Issue disappears with Mercury Software Only rendering. Happens with Mercury GPU Acceleration (Metal), which is the only option available on MBP16,1 with native GPU.

Same is reproducible with RX 5700 XT in eGPU in 10.15.3 (19D76).

When will this be fixed?

I have an expression that links to another layer. When you update a Layer name or Property name, then that name is updated in all the expressions that use that name (Extendscript calls this autoFixExpressions).

However, if an expression contains a Try/Catch statement, then no matter what, the names won't update in the expression (almost like AutoFixExpressions doesn't work if the expression contains a try/catch).

I'm not sure how I haven't encountered this before, as try/catches are useful just incase links are broken or are missing. I've posted this to Reddit, asking if this is a bug or a 'just me' issue, but it seems that it happens to others as well.

If a valid json footage asset is imported into a project and used for Expression data in a layer, and it is subsequently overwritten by an ExtendScript process, After Effects CC 2019 will not auto-refresh the JSON footage item in the project nor in any layer referencing the JSON footage layer. Choosing "Reload Footage" on the json footage item does not seem to do work either — this this did work in CC 2018. However, if focus is removed from AE, and a different process opens and overwrites the source of a JSON footage item, then focus is returned to AE, the JSON file updates immediately.

It seems like the method by which After Effects "refreshes" or "re-reads" changes to imported JSON files needs to be addressed. At least on macOS, it seems like writing to the imported JSON file via an ExtendScript is likely not being broadcast as an fsevent which is what AE might be latching onto to detect changes to the file.

Expected Result: When an ExtendScript process writes to a JSON file imported into After Effects, the corresponding data and any expressions using that data are updated immediately upon write.

Being able to paste from Premiere into After Effects is awesome, but there is a bug when pasting footage/audio from the Premiere timeline into an already existing composition in After Effects. The After Effects composition will automatically change duration without your input and it won't respect "Paste At Current Time". Do this to re-create the problem.

• Create a new After Effects comp, either from Premiere's "Replace With After Effects Composition" feature, or an independent project. Make it something like 10 seconds.


• Copy any footage or audio clip from a Premiere timeline into an After Effects composition. But make sure the copied clip is from a spot that is well into the timeline, lets say 2 minutes in.


• In After Effects, you'll notice that the copied clip is pasted at the same timecode that it exists within Premiere, at that 2 minute mark. Which is fine, it's a little annoying to have to bring it back to the beginning of the composition, but I can live with it. The trouble is that it automatically changes your composition duration to 2 minutes aswell. It doesn't respect your current composition settings.


• Every time you paste into After Effects your duration will change to a completely random duration depending on where you copied that clip in the Premiere timeline. Try it with different clips in Premiere at different times. Super annoying.


• I've tried "Paste at Current Time" in After Effects hoping that it would paste where I wanted it to, but it still pastes that clip at 2 minutes.

I understand having the ability to paste into After Effects at the same timecode that's in Premiere, that can come in handy alot. But lets have an option to just paste that clip wherever the playhead is, just like you can pasting layers within After Effects. And then lets also not have the After Effects composition change the duration settings on you every time you paste. I can't imagine a situation where you would actually want the comp duration to change on you like that, but if there is an need for this that I can't think of, can we atleast have it not be the default behaviour?

The latest AE Version is dumping huuuuge CRLOG-Files on the OS-Harddrive after crashing (which as everybody knows happens quite a lot).

The Files can reach 20-35gb each. These files are meant for UPLOAD and this is unacceptable.This concerns workflow AND data-privacy. ADOBE just wanted to upload 120gb of my data to their servers from my workstation. This is NOT acceptable.

WHAT ARE YOU UPLOADING THERE ? This is way more than just Crashlogs !!!

And this is blocking my OS, my upload-feed and slows my system down.

This is a perpetuum mobile of ****: AE crashes all the time, then generates files which make the system more instable,so it crashes more often and generates more files. Are you serious ?

You need to fix that!

Excuse my language. I am just annoyed.
Your support couldn't help me or navigate me to a spot where to drop this concern -- so they dumped me here on "how to improve AE" -

Thanks again... great Update.Great Service...

There seems to be a bug when working with parametric ellipse paths in tandem with trim paths.

It only seems to occur when the Start or End properties in the trim path are set to 50%, while the other is set to 0%. I've attached a couple videos for reference.

When the ellipse path position is adjusted the ellipse path will occasionally close itself, resulting in an unwanted half-circle. The half circle is a result of the Start property set to 0%, and the End property set to 50%. However, when the values are swapped (Start: 50%, End: 0%) it results in a completely different shape entirely.

Changing the group position in the layer doesn't cause this, and neither does the layer position. Other values for Start and End didn't seem to cause the issue either, only the 50/0 combination.

Some known workarounds include:
- Setting the value to something very close but not visibly different, such as 50.0001%
- Using an if/else expression to prevent a frame landing on 50% if the property is animated.
- Adjusting position with the group transform or layer transform properties

This has been tested on multiple machines running the latest version of After Effects (15.1.2), and while the issue occurs at varying positions, it seems to always result in the same shapes being created.
