After Effects Suddenly Quits when manually typing numbers into current-time display box. This bug has been plaguing me for over a year now on multiple different computers (all macs), multiple updates of After Effects. When I enter manual timecode into the current-time display box in the upper left hand corner of the timeline, After Effects will often suddenly quit. This happens very regularly. It happens to me on macs I've used at offices. It happens on my old computer, it happens on my laptop, I just bought a new computer and installed a fresh version of the latest program and it just happened twice in the last hour. This needs to be fixed!! Attaching screenshot of the error message.

In a 1080p comp, a shape layer is animated in position, the RAM preview is slow/laggy and play aorund 19-20 fps instead of 25.
But if I scrub the timeline, everything is smooth, reactive.
See the video attached, What can I do ?

Since updating to the latest build of AE (16.1.2 Build 55) my ram previews are again unstable at best (a problem I haven't had with a number of previous AE builds).

If I open a project that has a number of other reduced AE projects that have been imported into that project, my RAM previews stutter like crazy and the feature is basically unusable (again, a problem I haven't had with a number of previous AE builds… I’m so disappointed to see it return).

If I reduce that project, I can get an almost useable RAM preview, but there’s still a slight stutter to the preview.

I searched for a solution online, and someone suggested that if you have a pull-down menu selected during a RAM preview, you’ll get a smooth, real-time preview… and sure enough, I tried it and it worked—but as soon as I deselect the pull-down menu, the preview becomes stuttery and falls well below real-time. That tells me pretty definitely that this is a problem with the build... not the machine or my project.

Again, with the build before this most current one, RAM previews were pretty flawless. Please help!

As I said, I’m using the most current build of AE. Also, I’m using a Mac Pro (Mid 2012)(OS 10.13.6), 12 core, 64 GBs of RAM, with a Nvidia GeGorce GTX 980 card.

Thank you!

I recently upgraded to a 4K monitor. Now RAM previews consistently do not play back real-time. Changing the resolution of the monitor to 1080p OR resizing the entire After Effects application window to a quarter screen results perfect playback. I've tested this on several other workstations that either have 1080p or 4K monitors and have been able to reproduce this. They all have different graphic cards and plenty of RAM. I've played around changing the MST settings on the display without any changes.

Tested on several versions of:
Windows 10 Pro
nVidia 1070's / 1080's
32 GB Ram

Latest nVidia drivers plus several previous versions tested.

Latest After Effects: 15.1.2 (Build 69)

Currently the biggest bottleneck or noticeable speed degredation for me after getting a CPU with more cores and a lower clockspeed has been shape layers and vectors. If I have a comp with lets say 100 small shape circles, the FPS in After Effects drops to such a low level it is hard to even work. Since things are being optimized in After Effects and tasks are being moved to the GPU, this is one area of the program I would really like to be improved. Shapes and vector layers are very commonly used, so it shouldn't be such a huge bottleneck with modern hardware.

Preview playback is persistently choppy. Audio stutters as does frame rate during playback. This issue is SOLVED by hiding the timeline, which is not a practical solution every time I need to do a RAM preview.

I'm in CC2018 15.0.1 as suggested by Adobe support on the phone - it behaves exactly the same in 15.1.1.

CC2014 works absolutely fine in comparison.

I’ve reset VRAM and PRAM und also upgraded my OS. Nothing fixes it so far. I’ve tried enabling/disabling Mercury Transmit in prefs to no avail.

I'm on a Mac Pro Tower running High Sierra, 12 core 3.46ghz process and 48GB RAM. I was running El Cap with CC2017 but preview was still broken.

Can someone please contact me about this? Thanks. Support had no other solutions and suggested I post here.
