is this an impossible track?

[Tero Ahlfors]

You should get a track from the upper left part of the phone.

Thanks but could you explain a bit further.

Thanks

Its from the six seconds mark I am struggling with.

You do not need to use the whole screen as the tracking area. You need a plane that’s moving the same way as the screen so you could try and track only the top left part of the phone. It stays on screen and theres nothing in front of it.

Im struggling still. It keeps throwing off the track. Im doing the top left edge rim and buttons

[Christian Vilderman]

Yeah track is moving everywhere. So annoying

This area looks like the most probable place to give you a track.

it’s not the easiest track you are right about that, but I have had much worse so don’t worry about it 🙂

you should track your object and give the proper amount of information and not include the reflection or the finger. something like this would be fine. I added more pix used %:

later on you can even have this with no interruption of the hand and lower pixel used %

later on you are going to have to create another tracking matte for the thumb

at this part it get’s trickier because of an extreme perspective. you may have to manually do some work here or try giving the planar tracker more information.

here is the result. in the end it could use a little work but it’s no problem doing this manually.

here’s a good tutorial for even harder track with add to spline approach:

Now you are off to the fun part – rotoscoping of the fingers! 🙂
