After Effects is slow, slow preview, slow render, slow everything

[Petr Holusa]

I'm crying! I have 3700x 8 core and I can't play smoothly stupid simple animation in AE with sound. How I suppose to animate when audio is not synced properly?

ADOBE start using all cores [profanity removed by moderator]!!

Typical beginners issues.

You have to preview render the comp, or a part of it, to have realtime playback. Spend a bit time to learn the preview settings - they are essential for everything you do in AE.

Btw.:

AE uses all cores, but relies on high CPU clock speeds rather than many cores (from my experience, 4Ghz is minimum - higher is better). A lot of RAM is recommended (32 as low entry, 64 is good, everything above is best) as well as having very fast drives and a seperation between OS, project files and cache. GPU is still not that importend, but Adobe moves more and more effects to GPU. A mid-class Nvidia card is farily good.

I have got fresh new PC as above, 3700x 32 GB ram, RTX 2070 super, all SSD. What more do I need to handle just font generating and syncing with audio without 'Skrillex' style audio glitching fx. As I checked CPU usage, 2 core are barely used at all. And of course I do preview render. All green line

I do simple mographs, curves based mostly, nothing robust. 

Preview setting, I am paying for application to gat smooth animating workflow, not calibrating app all the time to have smooth opacity fade animation for sake. 😄

as i see in your screenshoot you use a mp3 audio file, so mp3 isn't good enough to use it inside after effects and most time you may get issue with mp3 file so try to use .WAV file and see if this can help you

[Martin_Ritter]

Yes, never work with mp3. Also make sure to have "cache before playback" checked in preview setting. And you are paying for the possibiliy to create whatever you are about to creating, not for a 1-click-software. AE is quiet complex. If you are not willing to understand and master all those little settings, you'll run into issues all the time. Sorry, but that's the deal. *Martin

This usage when using warp stabilisator. 4 minutes. Same speed I have on macbook pro 2017. 2.7 GHz.

[Martin_Ritter]

Yes, RAM is full, video data have to be read, calculation data have to be written... your CPU is idleing most of the time waiting for data. However, following the benchmarks, your CPU is already excellent for warp stabilisation. Bottleneck is RAM, obviously. *Martin
