- Thats really tricky: to 3D motion track a screen replacement to a device like an iPhone or iPad AAAAND to track it to a swiping finger at the same time.
The first part of my After Effects tutorial is beginner level and is about a simple screen replacement with Mocha AE via motion tracking. In the second part I'm gonna show you how to attach the screen to a finger gesture via expressions and reverse stabilization.
Credits to AE BLUES who originally came up with this reverse stabilization trick:

Your intro did a great job at making me think "oh how hard can it be" to "omg i never thought about masking fingers"
Yeah, masking fingers can be very fiddly 😎
OMFG, this is amazing!
This is what I have been looking for . Thank you for making this tutorial
Welcome 😎. I'm glad this tutorial was helpful for you
yeah, this is advanced - but very well explained. Thanks for sharing this!
Logged in to yt just to subscribe to your channel, really good work and great explanation! I will definitely be coming back to see you teach some new techniques! :)
The only thing is that the part about tracking the swipe made me think is it really worth the time vs just lowering opacity and adjusting the position by hand if u have moving markers?
Thanks, man 😎You are right. It’ll work by hand in most cases. Just saw it as a technical challenge to solve. However there may be cases where you want to be 100% precise. Capturing all the subtle micro movements.
Hi, great tutorial, BTW. But I didn't notice how you made the blue markers. Can you please explaine? Thanks
Thank you for this tutorial!Tell me pls is it absolutely necessary to have cross heads in the corners of green screen for replacing it after??
Thank you 😊. Not absolutely necessary as long as you can track the corners of the screen. But it must be 3 corners visible at the same time. But if camera and device are fixed you don’t need tracking points at all to replace the screen 😎
Great Stuff, which green screen app did you use, which provides the blue moving tracking tool ?
Thank you :). To be honest this was stock footage that already came with the greenscreen and the blue markers.
Thanks for this excellent tutorial! I’m confused about one thing though and maybe I’m just missing something obvious but how are the larger black “X” markers in the corners of the green screen footage staying in the same spot when the screen is swiped, but the smaller blue tracking markers in the middle move along with the finger swipe when the tablet screen was swiped in real life while shooting that footage? Was the tablet screen split into thirds or something, so that the middle part of the screen and the smaller blue tracking marks would react to the swipe but the bigger corner “X” markers would stay in the exact same spots real active to the corners of the actual physical screen on the tablet? Or were the smaller blue tracking marks added digitally in post after the footage was filmed? Sorry if that’s a dumb question but I can’t figure it out. Haha.
Hey that’s not a dumb question 😊. I hope I can recall it correctly: The black markers are actually black tape fixed on the screen to make sure that the screen can be tracked properly in case the tablet corners aren’t sufficient for the tracker. The blue markers are within the digital image. Hope that helps. If not I have have to watch my tutorial again 😂
That totally makes sense! Haha. I was watching on my small phone screen and definitely zoomed in as much as I could to try and see if they were done practically or if they were being displayed digitally and I was convinced they were digital and loaded on the device screen 😆. Thanks so much for the super fast reply!
Thanks Allot
Welcome 😎
Great but What if there is no tracking markers what can we do in that case?
Thank you! Regarding the sliding I would then try to keyframe manually.
The part that I wanted to learn, the swiping screen is soo complicated , my God.
Don’t bother. In most cases you can animate the swipe manually. I just wanted to demonstrate the most accurate way 😎
@@MichaelPonch thanks for replying, can you elaborate or point me to a place where I can learn how to do the swipe.
@@krishnataveras8734 basically you can follow my tutorial up until 3:35. Then you can animate the y-Position in the website composition via trial and error until the swipe matches the finger movement
@@MichaelPonch Thanks so much will give it a try
what if your screen is black? what's an alternative method to keying?
You can use the free ‘Unmult Plugin’. It eliminates all black areas 😎
Can give us your footage link ?
Bud what’s your laptop to edit your video??
I have a powerful graphics PC workstation because I make client stuff with it. I would choose a Macbook Pro if I needed a laptop
Michael Ponch Mac is I think the best sadly the price is just too high 😩
Very good video. But telling very fast. Please be slow
I wish I could do this, sadly I need to study more of this. Also it requires super high end laptops 😭
Hey bud. Not necessarily, if you can edit with your laptop, you can also run After Effects 😊
Which editing program do you use?
Michael Ponch my laptop is struggling to edit even 1080 😩
Very, very complicated.... I did this effect twice, once for a movie, another time for a tv commercial, both times much simpler approach, both times perfect results... But, ok, good to see there's more complicated way! ;)
Mostly I animate this with keyframes and nobody notices it 😂. I just wanted to find a way that is super accurate especially for jittering fingers 😂
I thought it was vfx not coding 🤯
