Hi there,

I swear AE didn't used to do this, but now my previews on the timeline are really slow and make the audio playback very choppy even with fast preview etc...

I've got the following

Intel Xeon E5-2630 v2 (Six Core HT, 2.6Ghz Turbo 15Mb)

32GB RAM

Nvidia Titan Black

Windows 10 64bit

So basically if I purge my work area then it looks like this...

(ie no green line)

straight after I did that screenshot it (for some reason) used RAM (ie the green line appeared slightly after the work area)

then when I actually previewed the work area (Shift 0) it added green before and after the work area when in my Preview settings I specifically chose "Work Area" for the range).

and

am I going insane or just missing something?

Thanks in advance.

Hey, I just had a similar problem and have heard of it before from a friend. I don't know if his will help but it was an easy fix for me and may help others when coming across a similar issue.

If your workspace window is set to animation there is a good chance that you have a panel on the right hand side titled Preview.

If not, go to Window>Preview (Or Command 3 for mac). In the preview theres a section that has playback Frame Rate, Skip, and Resolution.

If your skip isn't at 0 then your playback is skipping frames to preview your work faster making it choppy in playback and THIS was my problem. Such an easy fix but can be super frustrating. I have a feeling I changed it by scrolling along the side bar cause if you're hovering over some of the windows it will change settings in the panel.

Hope this helps, Cheers.

Hy Kyles,

Unfortunalty, what you say has nothing to do with the problem.

Of course the preview should be set to "0". If it is set to "1" it means that AE skip one frame of two when playing this why your animation playback may look wrong.

What we are talking has nothing to do with a wrong setting we are talking about a bug.

When you say your preview is slow and choppy, do you mean after it caches and you get the green line or before?

Also, what monitor do you have?

And Szalam

it's choppy after I cache (ie Shift 0) and it has a green line.

And my monitor is a Dell P2715Q, resolution is 3840 x 2160 at 60 Hz, source is DP (so would that make a difference?)

Found the culprit!

Dell (4k) P2715Q monitors have an issue. There is a Multi-Stream Transport (MST) option. Disabling it works to get previews running at a solid speed once they are cached.

depending on what's in your work area it may be caching more than just what's there. if you have a still frame that extends outside of it, for instance, it'll cache all identical frames too.

I suggest completely purging your disk cache under Preferences > Media & Disk Usage. Click both "Empty Disk Cache..." and "Clean Database & Cache"

see if that changes anything.

Ah ok so if I have a white solid across the whole timeline it could be caching that?

absolutely. if it's the same frame outside the work area as it is inside it would cache that too.
