"pingpong" is a function of the expression loopOut.
If you use it in conjunction with TimeRemapping, you can effectively "ping pong" your footage until the end of your comp or layer.
1. select footage layer
2. time remap the footage (you'll get 2 keyframes)
3. Select TimeRemap parameter and add expression.
4. In the expression field, type:
5. Stretch the out point of the layer (not keyframe) as long as you need.
ah...uhm...where is the expression field on CS4 AE?
You have AECS4, and you don't know where the expression field is? ;)
Three ways to get there (all are the same result):
1. Choose the parameter, then Animation->Add Expression
2. Choose the parameter, then Opt+Shft+=
3. Opt+Click on the stopwatch for the parameter
There may be other ways, but these are the ones I know right now.
Gads...I am feeling dumber by each reply from you...
"choose the parameter"
and yes, I don't know where the expression field is (for the entire movie).
I am looking for an online tutorial that "shows" me what I need to do...thanks for your help!
Enable time-remapping on the footage layer you want to bounce around, then apply the expression as laid out by Ko. These procedures are unchanged ever since AE 5.5 or so and also function in CS4, but that's probably just a slip of fatty fingers and you're referring to CS3. ;-)
Mylenium...and Ko...thanks...so easy!
I think I did what was suggested...when I hit the SPACE bar in AE...it ran to the end and then ran backward...so I rendered the COMP...but when I played in QuickTime it only ran once!
If you want QuickTime to loop, you'll need to implement the "loop" command in QuickTime. (cmd+L, or ctrl+L).
AFAIK, QuickTime only loops as cycles
If I extend my time line with the onloop expression where I put it now...will the rendering render for the added time?
So if I put the TIME REMAP in...THEN extend the duration from the original 2 minutes to 6 minutes...THEN re-render will it pingpong for 6 minutes?
Thanks again for you guidance on this!
i If I extend my time line with the onloop expression where I put it now...will the rendering render for the added time?
Yes. If what you want is just for the playback to ping pong, so you can keep your rendered movie as small as possible, you could always extend the comp to twice its original length, use the loopOut() Time Remap expression, and then loop playback in your viewer (e.g. Quicktime Player). The movie will only be twice as long, in that case.
I have a problem I never seen before, the espression loopOut() is not working for Time Remap in my AE CS4. It works for all properties but when I apply to a time remap value simply don't work.
thanks for any help.
Stop calling yourself Dumb!
Get startet with time remapping here
In general i would suggest buying an account at www.lynda.com for getting started from scratch. you'll then will never say yourself you're dumb.
