Glitch loop effect.

[Everett Bowes]

i think other people should definitely weigh in on this, but I think Final Cut, AE, Premiere, or your other editing app’s could do this, but I don’t know of any “automatic” way of doing it. It looks like you just need to cut your footage, like you would for any other video, with these jumps (or, “glitches”) in mind.

Maybe something to consider would be using After Effects with a plugin from videocopilot.net called “Twitch”. It’s a great plugin, but I’m not sure you can “twitch” the time remapping field. I’m not saying you can’t, just that I’m not sure. You might be able to. But if so, you may not be able to really control the final output of the glitches unless you just cut it (edit it) that way in an editor.

If it were me, I would just cut it in Final Cut Pro. You’ll have total control of your final results that way. Others can vote if this is a good idea or not, or, let you know if there’s a plugin out there that would make this easier.

Hope that helps!

It’d be pretty much impossible to do all those eddit’s manually firstly there’s probably 50 or 100 cuts, secondly a big part of the effect is the audio, as the loop point’s move closer together the pitch of the audio also (appears) to change though the footage doesn’t speed up.

It seems my only option is to create a rough as above then to import it in to AE to replaice dropped frames that there are. I had a look over the glitch plugin that you sugested and it does have time remapping so I’ll give it a shot, it sounds pretty intersting.

Don’t know if the audio is playing ion the youtube vid so here’s the same vid a’la vimeo

lights from ni-cad on Vimeo.

Guy’s I really really would like to find a way to do this in AE as I use this technique a lot in music production, now I’m working with visuals as well I was looking forward to achieving the same effect using footage from the samples I use.

If any of you can help or have any more suggestions I’d be really greatfull.

Impossible? Not really. It’s more of a cut/paste situation in your NLE. All you are doing is looping the footage at a faster and faster rate. The audio is another story. I’m a video editor so I can’t tell you how to do it, but I’m sure it’s pretty simple in protools or whatever audio app you have.

I don’t understand what you mean by NLE?

There is (as far as I can tell) no way to change loop in and out points in AE short of cutting each clip being looped to different lengths, this would take hours of work to simply replicate what is a very very basic function (moving a loop point) the footage does not speed up at all, the loops simply become shorter or longer or move to different sections of the clip, when I say it’s almost impossible to do this in AE thats true.

I’m pretty shocked that considering this is such a basic fundamental of edditing that it’s not addressed in AE or even by any third party pluggins. If it were a case of the footage simply needing to be sped up or slowed down then AE could do that, but this isn’t the same thing.

Nle = non linear editor. Fcp, premiere, etc.

Ae is NOT editing software and is not built as such. That the basic answer to all your gripes. It’s like getting mad at your plumber for not knowing how to make spaghetti for you.

I’m not trying to be hostile, sorry if it’s come accross that way, I really do need help finding a way of creating this effect in a proffesional app.

I’m not trying to knock AE really, this is the sort of thing that I think it would excel at and I imagined it would be quite possible. I would still describe this kind of looping as an effect, though it is actually is editing.

[Joey Burnham]

Okay. If you want to do this in ae Just follow the advice already given. Either interpret the footage to loop or else you’ll need to make a bunch of duplicate layers. You can speed up the footage using time remapping. This will vary the pitch of the audio as well.

[Richie Tovell]

The pitching of the audiio is actually a bit of an illusion, the clips audio is not speeding up or changing pitch, only the rate at which the clip is being played back is increasing, the audio content stays exactly at it’s orriginal pitch, the “percieved” rise in pitch is an artifact caused by the length of the waveforms becomming cropped shorter and shorter until there are only very thin slices of the original waveform remaining, which then play in faster succession.

I don’t have a problem with the audio, the problem is: it can’t be done by increasing the speed or pitch of a loop and to manually cut each slice would take hours, I’ve counted them and there’s over 100 slices, you can count them yourselfe by looking at the peaks in the audio waveform bellow, imagine each spike here needs it’s own accompanying clip. . .

Click on the image and you can see where the loops become shorter and longer again in much greater detail.

I’m pretty sure an Expression involving Time Remapping will work. The best folks to help you out hang out at the COW’s AE Expressins forum.

The youtube vid seems to be lacking audio, the vimeo version works.

In your post there, specify if you want either random playback or to with control using an Expression Slider control.

Oh cool, thanks Roland 🙂 sounds like it’s well worth giving them a shot, I’ll post the question over there and see what they say.
