How can I get random frames?

[Steve Roberts]

I’d try this to “wiggle” the playback:

1. apply time remapping to the footage.
2. apply the wiggle expression to the time remap property.
3. delete everything in the expression’s brackets except freq and amp. Ignore any error.
4. apply the Expression Controls Slider effect twice to the clip.
5. rename one slider to freq, and the other to amp.
6. making sure that the effects and the expression are visible in the timeline, select freq in the expression, and tie it to the freq slider using the pickwhip.
7. do the same for the amp.
8. animate the amp slider from 0 to whatever and back, to your taste. You might want to change the value of the freq slider.

Alternately, you could apply a random expression to the time remapping. I’m not sure how right now.

Anybody else?

maltannon has a preset he made to time shuffle really well and easy, or you can get andrew kramers plugin called twitch it does all your asking for its prolly the best plugin for that effect it comes out soon. untill then try maltannons time shuffler its on his site for free. then work from thier on color and size etc..

1) Dan has a quick stutter expression here that has variables for start and end (when to stutter):

2) But I really like this:

https://www.aenhancers.com/viewtopic.php?t=163

It used music to drive a stutter to the sound. See demo clips. Try different music for different movements. Turn off the little speaker if you don’t want the audience to see what a cool dancer your monster is.

This excerpt from “araknia” , page 2 of link above) was the best explanation on how to set it up if you don’t use the preset:

here’s some tips on getting this to work-

This expression goes on time remapping (Copy the expression, Alt-Click the Time Remapping Stopwatch and Paste)

To recapitulate the useful help put on this thread already:
1. Add music to comp first,
2. Select Menu ‘Animation’ – apply the Keyframe Assist – Convert audio to keyframes.
3. Add your videoclip to comp, disable its audio track, or you will hear strange clicks on final render.
4. Select the video layer in the comp, then select the menu ‘Effects’ – Expression Controls – Slider control ; you can set the effects layer name by hitting the enter key, if you are new to AE this should help. Rename the first Slider Control to frequence max.
5. Repeat step 4, naming the next Slider to ‘frequence min’
6. Do step 4 again, name slider ‘frames’.
7. Observe the “Audio Amplitude” keyframes layer created from your music track layer. you can expand the effects sub-levels to see the slider level called “Both Channels” . You can see a graph which corresponds to the audio of the music layer waveform.
8. Set the ‘frequence max’ effect slider you added to your video track to the peak value you observed in step 7, on my audio this was ~55.0 , then set frequence min to about 40.0 this gives enough animation effect for my liking. I set frames slider to -3.0.
9. Enable Time Remapping for the video layer (Layer>Enable Time remapping). This expression goes on time remapping (Copy the expression, Alt-Click the Time Remapping Stopwatch and Paste):

t=timeToFrames(inPoint);i=0;
while(timeToFrames()>=t)
{
min=effect(“frequence min”)(1).valueAtTime(framesToTime(t));
max=effect(“frequence max”)(1).valueAtTime(framesToTime(t));
a=effect(“frames”)(1).valueAtTime(framesToTime(t));
f=thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(1).valueAtTime(framesToTime(t));
if(f>=min && f<=max){i+=1-a} t++; } timeRemap.valueAtTime(time-framesToTime(i)) ------------------ I made a preset from this if you're interested, ask.

wow yikes sounds really cool . very intrested in that preset .

[Mike Clasby]

I’m working on a webpage for downloads (a shaky thing for me will take a few days), but can email the preset if you type you email out, like: me at yahoo dot com.

I’ll get on that download capability, ASAP.

Places like Putfile don’t like AE preset (.ffx) files.

yikesmike i would really reallly appreciate it . my email is

owiseo@aol.com

thanks alot bro .

[Mike Clasby]

Preset away!!!

I meant for you to type something like:

so any Bots prowling the web wouldn’t pickup your address, but maybe I watched Terminator a few tot many times.

Enjoy.
