CreativeCOW presents Separating Elements using Mocha 2 Tracking -- Adobe After Effects Tutorial


CreativeCOW.net. All rights reserved.


In this video tutorial Andrew Devis will show you how to separate out different elements in your footage to layers so that you can apply color correction or effects in completely different ways on each layer for that unique look you're looking for. Firstly, Andrew will show you how hard it is to separate elements natively using AE native tracker and then how easy it is to do using Mocha 2 tracking for AE.

Hi Andrew,

great tutorial!! This is really Uber-Cool! :D

I wonder can this be used to track people instead of using a greenscreen?
I want to turn myself green like Shrek, do you think this will work?

Btw, I have cs6 but can't find mocha. is it a separate program coming with AE or do i have to buy it for AE cs6?

Thanks a lot for your great tutorials!

Hi Camille

You should be able to do a search for Mocha and find it. I think it is in the same same folder as your Adobe applications - but have a search on your system and you should find it.

Mocha is for tracking a plane - so it isn't really the thing to track a person with a single track as it would probably need lots of tracks to do that.

To make yourself green you could use the roto-brush tool - I've not done a tutorial for that but if you do a search you will probably find one. The key is to make sure that the background is bright and you are distinct from it, then you can cut yourself out with the roto-brush tool and colour yourself however you like!

BUT - if you are just wanting to change the colour of your skin - you could do a secondary colour correction and select your skin colour and affect just that?

Try this technique out first as it may save you some work and time.

Hope it works out well for you

Hi Master Yoda,
I am going to ask a simple but yet profound question: What makes Mocha (sounds like coffee) better than Rotoscoping? Thanks...

I think I am on to something!!!!!

Yoda! Flattered, I am!

The reason we are better for rotoscoping than say, rotoing by hand or rotoing in AE, is because we use our planar tracker to drive the track, like an computerized roto intern, mocha looks at the basic motion of the object and drives the mocha shape along with the track, and you just correct it. This makes it to where you use less keyframes (about a third overall of what you'd normally keyframe) and cuts your roto time in half. It's why we ship with AE in the first place, to enhance AE as a program with our planar tracker and our rotoscoping abilities.

With V3 we added a lot of new features for roto that make them even better, so you can stitch roto shapes together, have access to all the keyframes, and we have a new transform tool that allows you to make large (and uniform) translation, scale, rotation, and skew changes to all or some of your points in a shape, as you so choose.

And then you can import our data into AE as a mocha shape effect (respects per-point feathering) or you can import our shapes as a spline (doesn't respect per-point feathering but is way faster).

We also have tons of free tutorials on rotoscoping with mocha here: http://www.imagineersystems.com/videos?tagFilter=roto&sortBy=Newest

Let me know if you have any more questions!

Cheers,
Mary

Thanks Princess Lea,
I haven't really dabbled in Mocha YET and I stress the word YET. I am really looking forward to exploring the tutorials you mentioned above. I think I will eventually have to get the upgrade. Is there special pricing for teachers? Thanks for your help... Chewy :O

"I was under the assumption that CS6 Production Premium would have the most updated version of Mocha. So, how would I go about getting that free update (excuse my igorance here)."

Hi Ian,

Unless you have mocha V3, you will not be able to upgrade to the free point release. Because of our separate development cycles, the delivered mocha AE inside of After Effects is actually version 2.5. This has the same powerful planar tracker we put inside every version of mocha, but is missing new features like colored matte passes, dope sheet, nested folders, multiple layer selection, the join layers tool, our new camera solver, out new lens correction tool, and the rest of our features.

If you would like to upgrade to mocha AE V3 or mocha Pro V3 from your version that ships free with after effects, it cuts the price down significantly, and you can do that in our store here: http://www.imagineersystems.com/upgrade-guide

The upgrade links inside that info page will take you to our store.

I hope that helps!
Mary

Hey Master Yoda (I hope you don't mind my callig you that... I love yoking around- I am cracked). You indicated the following

Also, Mocha for AE 3.1.0 just shipped, so if you go to the imagineer website you can get the update free of charge

I was under the assumption that CS6 Production Premium would have the most updated version of Mocha. So, how would I go about getting that free update (excuse my igorance here).

Regarding the same clip being used in AE and Mocha, I watched your tutorial on that. There seems to be a similar issue when using footage in AE (HD) and then using that footage in Premiere Pro in (SD). Premiere Pro won't let 3D Camera Tracker or Image Stabilization export from AE to PP. Perhaps it is all confusing what I just wrote. Thanks Master Yoda... this jedi knight wants to learn with the BEST!!! Thanks

Hi Chewy
The real Yoda has spoken! All others are are mere padawans in comparison to Mary. Sorry if i led you astray with 3.1.0 (but it's worth buying the update anyway if you do much roto work).

Hey Master Yoda,
I hope all is well. I have been watching the majority of your tutorials. Keep up the great work!!! I am a teacher as well so I appreciate your ability to convey useful information. My question: You mentioned in the above tutorial that Rotoscoping would be a painful process vs using Mocha to separate the boat from the water. Is the newer version of Rotoscoping better in cs6 than when you made this tutorial or would using Mocha still be the best solution. Thanks.... Chewy
@Ian Hagerty
by Andrew Devis
Hi Chewy :o)

You can roto in AE but Mocha for AE ships with AE and is by far the better tool for this kind of thing. Not only that, you can also use it for roto shapes and the like, so if you can get going with Mocha you will find it a valuable tool to learn. Also, the Imagineer Systems website has lots of training on it for free and is a great resource.

One thing to bear in mind though is that you must have the footage the same in both AE and Mocha, if you accidentally use the wrong pixel aspect ratio or frame rate then the info you get out of Mocha won't work in AE.

Also, Mocha for AE 3.1.0 just shipped, so if you go to the imagineer website you can get the update free of charge.

Let me know if you spot any death stars ...

I see Roland has replied to your post, and I would say the same thing. Check you have Mocha Shape installed before going any further. If not, get back to Roland as he will be able to help you.

Hi Paul

Thanks for the comment and I agree with you. I can't go back on this tutorial, but for the newer Mocha tutorials I've done on the cow I have included the footage to play with.

Thanks again

Hi Michael

You are right of course, it probably would have been faster. Also, I forgot to check the perspective tick box in mocha! However, what I was really trying to do was demonstrate the principle on a relatively easy clip. I hope it will still be of some help to people.

Thanks again for your comments.

Yes, I have done it that way. On the shots for which I did it, it was very easy. However, as you are well aware, different shots can vary the ease of a technique greatly. I'm sure there are situations where doing the Mocha technique would be much better. On the boat shot you were working with, I believe the track matte technique in AE could be faster since it doesn't require rendering out your work area, bringing it into a separate program, etc. On that shot I would think you'd want to track the scale too.

Of course, if you have a good track in AE, you could just apply that tracking data to a solid layer that you put your mask on and use that layer as a track matte for a duplicate of your footage.

Hi Michael
Good call. Have you done it that way, and if so, is it as easy as it sounds? My experience is that doing it directly in AE always ends up being a lot more fiddly in practise. There is always a way to do it, it just takes time and experience to work it out. The thing about the mocha approach is that it is so quick and simple

Thanks again
