Can I scrub the timeline in AE (CS4)?

[Vic Noseworthy]

Hi Dave,
Thanks so much for your help. I’ve been looking at the link you provided, and it indicates that scrubbing is possible. Specifically, it says:
Manually preview (scrub) video and audio
To manually preview (scrub) video in the Timeline panel or go to a specific frame, drag the current-time indicator.
However, when I try it, no go. What happens is that, after I release the mouse button, the preview jumps to that frame. But, the preview doesn’t scrub (as you indicated it wouldn’t).
It’s odd that the link to the help page on Adobe’s site says scrubbing can be done. Is this a glitch with the program? Or, did I misunderstand the instructions?
Thanks again.
Vic

Hi, again, Dave.

The closest thing (in fact, the only thing) that resembles scrubbing is when I click and hold the ‘Next Frame’ button (in the Preview window). That works pretty good, but I just wish there was a keyboard command to trigger it. I have to use the mouse and actually click on the button and hold it.

Other than that rather cumbersome ordeal, I don’t see any other way that even remotely resembles scrubbing… or, for that matter, even single frame advance. And, even when a segment has already been renedered, makes no difference.

You said, “…each frame you want to scrub must already have been rendered via RAM Preview”. It sounds like there’s a way to scrub once rendered. But I don’t see it.

Sorry about the confusion, but I really am confused. Can I ask: How do you work around it (scrubbing, I mean)?

Thank you again.

Hi again!
I just did a search and found one of your previous posts, Dave. Anyways, even though I’m not exactly sure what’s changed, I seem to be able to scrub, now. I just hold down the option key while scrubbing, and it works. I’m sure I tried every combination of Alt/Command/Control/Shift keys previously, and nothing seemed to work. In any case, your post helped me!
Thanks very much!
Oh, and maybe I’m in the Twilight Zone right now, or something, but it even seems to work without having rendered the frames. Awesome… hope it keeps working. :^)
Thanks again!

Actually I have faced the same problem before.

There is a kind of scrubing that sometimes stops working for me. Even then, the image renders in a very low quality, but for the purpose of pre-viewing the animation before RAM preview, it works. I usually make RAM previews every time, so the scrubing works very well with the rendered preview done.

The problem is something I haven’t been able to find a button to toggle it on and off, but resetting the preferences has worked. Hold the CMND+SHIFT+OPTION very quickly after opening the application.
