Playhead playing at 0.5 speed. HELP?

[ItsRaty]

I'm quite new to after effects so i'm hoping I'm just being stupid and this is an easy fix. After Effects has been running fine up until yesterday where i changed a few settings to help my preview run nicer. Whenever I now try to preview my work the playhead moves at 0.5 speed. The area above the playhead, which is usually green, is blue as well. Please help.

Change it back.

I've changed everything back (apart from emptying cache) and it's still going at half the speed

you can reset your preview panel here:

after your reset your panel, check again and show us a screenshots of what it sayes in the info panel about your playback

The area above the playhead, which is usually green, is blue as well

that's not related. blue means the frames are stored to disk and Ae will now save them to RAM instead of re-render them all over again.

you should read here about what to expect when playing back in After effects:

Preview without rendering in After Effects

watch this:

Preview without rendering in After Effects

and this:

After Effects CS6 Preview panel

and comeback if you still have questions.

THANK YOU SO MUCH, the play head is going at normal speed now. How do I switch the color back to Green??

How do I switch the color back to Green??

green means the preview is in RAM. blue means it's in disk. don't worry about it

here's a nice tutorial about it:
