Hi there,
this has been asked before, but none of the given solutions solved the problem for me.
As soon as my projects get a little bigger, Playback is limited to just a couple of frames, before it jumps back to the first cached frame.
On my current project, most of the time playback doesn't even start but prompts me with the message:
After Effects error: Cached Preview needs 2 ore more frames to playback (actually the german version of it: After-Effects Fehler: Wiedergabe einer Cache-Vorschau benötigt mindestens 2 Frames.)
When this Error occurs, After Effects only uses about 2.5 - 5 Gig of the installed 16 Gig RAM, although i set it up to use 12.
CPU usage is arround 15%
No other CC applications are running, browsers are closed.
On this specific project, i have a couple of audio layers and 4K Video Footage (XAVC-S / .mp4 from a Sony A7SII)
The "rewinding" Playback after just a few frames also occurs on projects that have no video footage but are done fully within After Effects.
My PC Specs:
Windows 10 Pro 64bit
Intel Core i7-4790 @ 3.60GHz
16 Gig Ram
AMD FirePro W5100 (FireGL V)
After Effects CC 14.0.1.5
Windows and After Effects running on a 232 Gig SSD with currently 36,5 Gig available space.
Some of my footage is on this Drive, most is on a regular HDD (450 Gig/360 available)
What i already tried:
- Raising the allowed RAM from 8 Gig to 12.
- Purching the Disc Cache (Its currently set to 15, but raising it didn't change the result)
- Cleared Databank and Cache
- Unchecked "Reduce Cache Size when system is low on memory"
- Reduced Viewer resolution to Quater and turned on "Fast Preview"
- And of course i closed, reopened and restarted the PC...multiple times.
Thank you!
For persistent causes of this issue, today's bug fix update should solve it.

I know this might sound too simple, but it sounds like you've accidentally set your Work Area to play only 1 frame. Grab the Work Area bars above your timeline and drag the Start handle to the beginning and the End handle to the end (or really, drag them wherever you like, as long as they are spaced apart more than a frame. If you're not sure what I'm talking about, try hitting this set of keys: Home, B, End, N. Hope that does it!

Thanks for your reply. Sometimes it's the most basic things that are easily overlooked. But it's not the Work Area in this case. Start and End Point (N,B) are definitely more than just a few frames appart.

Or first B and then N for that matter. But no, i did not mix them up and there is plenty of room inbetween.

Hi cyperfection,
Did you solve this issue yet? Have you tried any non-Long GOP formats or transcoding the Long GOP footage to an mezzanine/intermediate codec?
Thanks,
Kevin

Hello Kevin,
I have the same Problem, here:
- After starting AE i can render a couple of frames. But its not rendering the entire work area.
- After the third time I get the message: Wiedergabe einer Cache-Vorschau benötigt mindestens 2 Frames.
My PC Specs:
Mac OS 10.12.3
Macbook Pro Retina (mid 2012)
Intel Core i7 @ 2.6 GHz
16 Gig Ram
NVIDIA GeForce GT 650M 1024 MB
After Effects CC 14.1.0.57
After Effects running on a 232 Gig SSD with currently 40 Gig available space.
Footage are stills (png or vector)
What i already tried:
- made sure working area is more than 2 frames via N and B
- Raising the allowed RAM to 16
- Purching the Disc Cache
- Cleared Databank and Cache
- Unchecked "Reduce Cache Size when system is low on memory"
- Reduced Viewer resolution to Quater and turned on "Fast Preview"
- closed, reopened and restarted the PC
This is pretty urgend.
Thanks a lot for your help!

Hi ChristianH,
What is the frame size of your imported graphics?
Thanks,
Kevin

Interesting, that's the only time I've seen that message come up. What if you copy and paste your layers into a fresh sequence (assuming that doesn't mess up a ton of other stuff in your project haha). Or importing your comps and layers into a new empty AE project?

Thanks for that! Was having the same problem. Did all the cache clearing stuff... no go. This worked. (Knew it was one file as all others were previewing fine...)
Thanks again!

Hey,
I noticed that the use of the puppet-pin caused the problem of previewing in my case. Maybe you can uncheck the visibility in every single of your layers to see where the problem is.
