HELP!! how do i control strobo effect with audio??

Hi Henriette,

There are many tutorials on the topic. The top two in this
list are probably the most relevant for what you are trying to
do. Although he uses a plug-in to extract the keyframes from
the audio, the same can be done using AE’s built in tools as the
other tutorials show.

cheers! I already checked the first two this morning, really useful, but actually now my problem is that once I’ve set the parameters of duration and period of the effect as they should be as “average values”, if i then connect them to the audio, the parameters that i set previously arent mantained. I’d like to be able to keep the parameters i set as “starting points” on which then the soundwave effects.
Is there any way to do that?

I’ll check the others tutorials in the meanwhile, anyways, thanks again!

Hi Henriette,

If I understand you correctly you are applying an expression to link object “A” and your audio
and the expression is overriding previously animated parameters in object A?

Depending on what exactly you want to do-

You could precompose object A and then apply your expression to the precomp-
or
Try Parenting object A to your music null rather than
using an expression.

hi Andy,
yes, I have to create a flickering effect on all the video track, linking it to the audio in order to make it become faster or slower depending on music. if i precomp it, it won’t mess up the “average” settings i first give to the effect?

thank you!
