Re: Mask Question

You need to mask it over the top on a new layer. You can either do that by creating the mask on a new and set it to track matte the face layer, or by copying the original layer and masking that layer

If I'm understanding it correctly, you probably just need to pre-comp your layer to stop the mask from distorting or shifting your effect. Martin Brennand Product Manager Mocha - Boris FX (Imagineer S

If you already have an existing mask that you want to apply tracking data to, there's a number of ways to do this. Use a solid: 1. Cut and paste your existing AE mask to a solid 2. Paste the tracking

Richard, STMaps are colour fielded maps like UV maps that are used to map and generate lens distortion. They are common in compositors like Nuke or Fusion and are often created by programs like Mocha
Making background track with video

I've replaced a blown out sky in a shot by making it transparent using a luma key and placing a stock image of a sky on the next layer down. Then I did a camera track of the video which gave me a bunc
Re: Making background track with video
by Martin Brennand 11 months ago
If there is a perspective shift in the shot, then you may need to do a full 3d card or corner pin, but if it's just tracking shaking you may be able to get away with a simple transform How big is the
Tracking sky replacement with camera reframes
by Zach Worden 12 months ago
I shot an interview in a room with a cityscape in the background. The sky is completely blown out, because it was so much brighter outside than I could get it inside. I was able to replace the sky wit

Can you add 'digital makeup' or a 'tattoo' without Mocha?

You would probably need to do it in patches. since the face is made of of tiny planes (forehead, cheeks, cheekbones, chin, nose side, nose bridge etc) you'll get unnatural motion if you try to splay a
mocha tracking

I am trying to use mocha to track a face to add a monster like skin. I am having trouble as the track seems to move. If I use corner pin data the track does not seem to line up with the image I am try
Re: mocha tracking
by Martin Brennand 1 year ago
Again, it looks like you're applying the mask to the corner pinned layer. Adding a mask to a layer that is corner pinned will change the dimensions of the layer and therefore change the way the corner

Tracking 3D Text in Apple Motion Using Tracking Data From Mocha
by Thomas Tapp 5 years ago
I'm trying to figure out how to track text in motion using tracking data from mocha. The data worked great for shapes, masks and other objects, it just won't track the text. This is what I'm doing: I
