RAM PREVIEW ERROR: need 2 or more frames to playback
I am working in CS3 on a 2 x 2.8 Ghz intel Xeon 8 GB ram
I have worked with AE 10 years.I set my preview area on timeline and ram preview options in time control and no matter what the duration is I get this message,
AFTER EFFECTS ERROR: RAM PREVIEW needs 2 or more frames to playback.
I have reinstalled After Effects, changed memory and cache, purges All (which sometimes works for a while ) BUt it is reoccurring.
Anybody have similar problem ? Is it hardware fault ?
THANKS !!

Thank-you for this information, very interesting!
Is this also the case for,
APPLE PRO RES 422 and other FULL HD CODECs ?
-
no, I don’t think Apple ProRes has that problem. Others might, but it depends on the codec.
Most codecs built on Mpeg or a variation of it will have this problem. I believe this is the case with native HDV.

I get this error constantly, and it seems completely randomly.
Purging every time I have to do a RAM preview for a client is ridiculous.
Also it seems that sometimes the length of my ram previews get shorter and shorter.
On a brand new MAC with 8gig ram I should be able to preview more than 4 seconds on a SD comp.
No footage involved just PSD and AI, and AE solids, shapes etc.I just quit and relaunched AE now I can preview the full 10 secs.
It’s very hard to pin down what is causing it.
Thank You

We still experience this problem as well, and we are using 1080p footage. I really do not think it’s an issue with our footage, and the only way we can get around the issue is by restarting after effects.
However, SOMETIMES simply adjusting the work region will fix the issue on OS X. It’s totally random though, and sometimes is does nothing.
We are using CS3 on XP Pro, and OS X. Any other tips?

Disable Multiprocessing.

Got the same Problem, looked all over the internet for the answer but nothing worked for me.
But then i found the answer myself, or at least it worked for me.Go to:
Edit – Preferences – Memory and Cache and make sure that your Maximum RAM Cache Size is is 60% (or something like this, mine was 2% only, don’t know why and how it got to 2 %, but now it is working)Hope it is help, it drove me crazy for couple days.
Best regards from Crimea.

I have never seen that error until today—–and I can’t seem to do *anything* to make it go away.
Life is full of funny particles.
