How to Loop Compositions PERFECTLY | After Effects Tutorial

Hey everyone, the expression you need is just:

loopOut();

But! Make sure to watch the whole video to know how to solve the flickering issue you may get on certain loops! Cheers!

Hi, I like your videos, but have you done any tutorial on how to make it loop forever as .mp4 file , because when I render it, it just shows the loop for 30 second and then the video stops. Thank you for your support.

i am trying to make an animation drawing video as a gift for my boyfriend, so i can cheer him up.
this video helped me on the first step of the video, so i am really grateful. thank you so much!

Doesn't work on After 2018 😢 i still have no idea how to fix the flickering problem

Thanks, sir.

Amazing tutorial, directly to the point, thanks TipTut!

And could you give knowledge of alpha and luma and topic to be covered masking. I know how to do but my fundas in this are not clear.

Like these simple trick, give some simple tricks to work on character animation and all expression that helps in our daily routine and white board animation.

quick and helpful. Thank you ! <3

That helped to remove flickering. Weird issue.

Sadly didn't work for me. Only shows first frame and is black for rest of the composition.
Steps that worked for me (After Effects 2023):
1. Composition > Trim Composition to Work Area for the composition you want to loop
2. Make a new composition and drag in the composition from Step 1 into it
3. Right click the layer > Time > Enable Time Remapping. Two keyframes are made at beginning and end of composition.
4. Move to the very last keyframe, step backwards one frame, and create a new keyframe.
5. On the very last keyframe, double click on it and change the time to 0. Then double click on the last keyframe and delete it from your composition.
6. Alt click the stopwatch next to Time Remap to activate it under the layer. Copy paste this code: Property > LoopOut(Type="Cycle", numKeyframes = 0)

Now it will repeat for as long as your workspace is. Hope this helps!

still doesnt work,,,,when i cut it and pre compose..it doesnt follow the time that only 2 seconds for the animation..but keep 17 seconds...

Works like a charm!

Great explanation. I don't know why I hadn't subscribed before. Always good work.

Great tutorial!

For those that still struggle witht the flickering problem at loop frame. You need to shorten inside the comp that loops by one frame (just go to the end of the looped comp and drag the right end of the second blue and gray line by 1 frame and then you can do like him and add a keyframe right before loop on layer comp like he did. If that still doesn't work, make sure you rasterized your comp layer (little sun)

Nice! Thank you!

In my case only one keyframe (start) is appearing not the end one.

Anyone else thinking why such a crucial and simple task isn't a built-in feature?

thank you!

So helpufl. Thank you for sharing.

Thanks for this!

You just saved my life. THANKSS DUDE!

Thanks for the tutorial! I had to watch the video several times but I think I got it? I'm very beginner with after effects. I think you have to delete the extra layers that you didn't cut off?

That doesn't work. If I delete the last key, it won't loop. If I don't delete it, it will loop only once

works like magic! thank you so much saved me a lot of time :)

It still didn't work for me 🤕 I followed every step and making sure with all the details like precomposition, the length of the composition, and placing of the keyframe and such, it is still flickering a blank frame. Btw my ae is cc2019

God this just changed my lfie

niiiiiiice

Thanks

Ty!

I don't get the keyframes when I apply time remapping. And even when I put in the keyframes by hand or not, it would not loop

Not getting a time remap endpoint keyframe when I enable time remapping. Not sure if that would be why this isn't working for me. Even if I drop my own in there it doesn't work after anyways.

Brilliant. Simple & easy to follow. Thank you for the tutorial!

Dude, can you tell me if it's possible to copy a composition? When I duplicate a composition and change the duplicate, the original is also changed! How do I fix this? Thanks!

Awesome dude, thanks 🤘🏼

thanks a lot, mate! it took me a bit to understand ALT-key pronounciation :D (i'm not a native british speaker....) however thanks for keeping it short and on point!

Thank you! This is extremely helpful! :)
For all you fellow n00bs: if you're confused about the pre-comp duration, select "Adjust composition duration [...]" when you create it.

Tried on After Effects 2020, and does not work. BUT, it works on After Effects 2021. Fyi

How to stop pingpong after a few cycles?

I know I must be doing something wrong. My comp is 2 seconds long but every time I use the loopout expression and extend it the animation still stops at 2 seconds.

For those of you still struggling with the the flicker issue - You don't have to create or delete keyframes at all. Not necessary. Just turn on the "continuously rasterize" icon (the little star burst) next to the "shy" icon. That will get rid of the flicker without the need to mess around with keyframes!

**ADDED NOTE - Obviously the "continuously rasterize" isn't always going to be the ultimate answer or give you the results you want. It can be just as frustrating at times. Things like 3D layers, cameras, audio or nested comps can give unwanted results. It really is a hit or miss sometimes.
Either way, I'm so glad that my comment has been able to help so many people. Happy comping!

Thanks a lot, I would have never figured it out by myself!

Thanks for the update on this, the code is def easier. However I've been trying the recommended flick fix for a long time and that new key frame is always just becoming the new flick point. I also tried that other method and nothing's better. I'm def blaming Adobe for this.

Thank You! I've been looking for tutorials but every one of them didn't work.

This one worked perfectly! Thank you!✨💯

life-saver! thank you so much. this helped a lot

i have followed these steps and it still does not loop
