How to manually create keyframes for mask in Mocha ?

[Letty2019]

Hi, I have a small 15 frame scene....  it's complicated, so Mocha won't track it well...

No problem, I simply use the pen and outline my mask.

After I make my mask outline, I click on "Key +" bottom right, to make a key frame,

then when I do the next frame, the first frame doesn't stick?   ... and the mask in frame one, looks like the mask adjustment I made for frame 2.

Can't make a manual mask in Mocha.

What did I do wrong?  

Thanks!

Spend some time on the Boris FX website looking at the tutorials for Mocha AE. There is a section on manually adjusting the spline and doing roto. 

The workflow is track first, then switch to the Adjust Track tab in the Classis UI. There are a couple of excellent tutorials. You can't manually adjust anything unless you are in the Adjust Track mode, you just reset the search area.

Thanks Rick, will do.

I'm trying to finish that graffiti on the bus bench you helped me with earlier.

I made a new image in photoshop of the entire original bus bench ad, then photoshop'd out the boy, now I'm attempting to mask that bench and use mocha to have the new image follow the mask.   I think if I can mask the whole bench ad then have the new image follow it, it might work.

I was able to half and half like you said, but I can't sync the 2.  So I came up with just making a new image, insert the graffiti into the image using photshop and then use mocha. I think I'll get lucky, lol worth a shot.

Thanks again!
