Error when I do a RAM preview
by DennisV on Aug 18, 2007 at 1:39:21 am

Hi Guys,

When ever I do a RAM preview with After Effects CS3 I get this error "After Effects error: RAM Preview needs 2 or more frames to playback." I don't have this problem with After Effects CS2 (7). Do I need to set something differently? It have done this since day one.

Thanks,

Dennis

I've been getting that and other related issues as well. It seems as though CS3 runs out of memory very easily! I have a relatively beefy system--Core 2 Duo, 2 gigs of RAM, decent video card, and I'm not throwing alot at the app.

Sorry I don't have an answer for you, but just wanted to chime in and let you know you're not alone!

You've most likely limited your work area to one frame, so there's nothing to preview.

Reset the work area to the region you want to preview.

No my project is a 30 second DVD menu. I have this problem with any project and none of them are less than 30 seconds in length.

I just started getting the same error. Found this post because I did a search on it. Anyone from Adobe have any advice? I've been running CS3 for a few weeks and today it just started.
Mac OS 10.4.9
AE CS3 (8.0.0.298)
Lots of use of Trapcode Particular and Shine plug-ins

The first guy was right on. I had this error on just one of my projects but not the others. I changed the work area and it worked right away. The way to test if this is the problem is to select the Composition Menu: Trim to Work Area. This trim your timeline to the currently selected work area (in my case 1 frame). Hit control-z to undo it. Then look for the blue handles below, not above the timeline. Grab on the left side and drag it out to the end of the timeline. This should fix it for you.

Best of Luck!

quick clarification - blue handles below the timeline markers at the top

I'm not sure if Mojo was proposing a work-around to a bug, or clarifying user error, but although this is certainly possible as a user error, there's something else going on.

I haven't tried mojo's fix. But it's clearly more than user error.

That said, I'm responding to both clarify that
1. Adobe shouldn't write this off as a noobie user error.
2. The problem rectified itself when I did a Purge>All (so far), leading me to believe it has something to do with memory.

Note: I haven't yet upgraded to X.4.10 and AE 8.0.1 (I'll do it as soon as I can get a break in projects because I've got OpenGL issues as it is currently)

Hope it helps,

I got exactly the same error message. The problem is kind of both a bug and a user error. The project comes up, or goes into, a state where the work area is set to 1 frame. So a simple user adjustment fixes it. I'm on the latest version of CS3 with a quad core intel mac and 10.4.10

I hope this helps.

I've been getting the same error - also working with a lot of Trapcode effects. When I hide the layers using Particular (Trapcode) I can RAM preview with no errors.

might be a bug in the recent Trapcode CS3 releases?

That sounds like it's coming from a different problem. Maybe the layer with the Trapcode effect is set to only display one frame (?).

RAM preview Memory Problem
by jaycordova on Sep 21, 2007 at 5:09:28 pm

I've got what I think is a memory related problem with RAM Preview. Machine is 2 x 3 GHz Intel; 9GB of memory. AE CS3 memory settings are the default: Max Memory Usage 120% = 3.0GB, and Max Ram Cache Size 60% = 1.8GB. No apps running other that AE CS3.

I can't preview over about 30 seconds at 720x486, if I'm lucky. Go figure. Further, if I shift the work area to a totally unrendered area, it won't get rid of previously rendered frames in order to render frames in the new work area.

And it's 30 seconds max with a test comp using only straight video and audio (no filters at all).

If I "purge all", I only regain the ability to RAM preview less than 30 seconds of the timeline.

Other notes are that the green rendered frame indicators on the timeline are not correct sometimes. I can get a preview of a work area only half covered with green "rendered" indicators.

Does anyone have any idea what might be wrong here??
