DavidDRAM preview not really working?

When I try to RAM preview, the green line comes up to show what has been rendered, but then it starts to disappear and there are gaps in it after it has already gone past it - and finally, nothing gets previewed...

I am working with WinXP, 1 Gig RAM, dual core 3.0 Intel.

Sounds to me like you aren't actually RAM previewing, but just hitting the space bar and hoping for the best. I'd recommend looking up the term "RAM Preview" in AE Help so you get a handle on how it really works.

I am guessing it is the fact that my green ram preview is only giving me a tiny bit of a RAM preview because I don't have enough RAM. I set up a timeline that was 6 seconds long, RAM previewed it and it only gave me 3 seconds of it and then stopped.

[DavidD] "it only gave me 3 seconds of it and then stopped"

Yup. Sounds lke insufficient RAM to me, too. Except for one thing: even if you don't have much memory, RAM previews don't stop... they keep repeating as much of the comp as the RAM will hold until you hit any key or click the mouse, ending the RAM preview.

I wonder why yours just stopped? That's the real head-scratcher.

No, you are right. It doesn't stop, but it only renders out part of what I need and then it play that. My mistake if there was a misunderstanding.
What is the minimum for RAM for AE 6.5? I am working with hig-res images, so I wonder if that is it?

With AE 6.5, 512 MB RAM is scraping the bottom of the barrel. It can use as much as 2GB.

What do you mean by high-res pictures.... darned big stills (think 3000x4000 or more) in a regular sized comp, or one of the too-damn-many forms of High Definition TV?

Oh, it doesn't matter. Either way, you don't have hearly enough RAM. 3 Seconds ain't nothin'.

Hi,
have you tryied to Ram preview it a 1/4 resolution (or less),
just to see if it renders all the way through?


cheers.
