  • Rotocoping with Animatte – possible?

    Posted by John Steventon on November 26, 2010 at 5:56 pm

    Hi everyone,

    Got a bit of a brain-fart going on right now re rotoscoping using Animatte.

    Simply, I’ve got a locked off timelapsed background with lots of stuff going on and in the foreground, a cat walks across screen, how cute.

    It’s the cat I need to paint over the background.

    It’s only a couple of seconds, and I’m more than happy to paint the cat in 50 times. The only thing is that (and here’s the brain fart) my head can’t work out how to key-frame animatte properly.

    I can split the clip into 50 individual frames and paint out each one which works – but I just can’t work out how to do this every ten frames or so.

    Ie, cat is sitting there – paint out cat. Cat starts to move, paint out cat – 10 frames later, cat is across screen – adjust paint to make sure cat is gone but background still clean – move ten frames… rinse and repeat.

    But all I end up with is a bunch of different paint jobs on screen all time – so I’ve got a bunch of holes punched into the timelapse background.

    I can do this easily in After Effects normally – but the suite I’m in has nothing apart from MC5 – and no way to get anything else. Hence my workaround of splitting into 50 frames.

    But surely I’m just forgetting how to paint and alter onto one effect and keyframe the changes, instead of needing to split into 50.

    Or am I dreaming?

    John

    Hi, as far as I can remember you cannot animate the animatte if you use the paint brush tool. If you draw round the cat using the polygon tool you can then add keyframes and adjust each point. The trick is to add loads of points as if you add more later it can muck up previous keyframes. For a complicated shape like a cat you might want to use something else. Alternatively you might be able to pull a key from the cat (depending on colour).
    Good luck. Matt.
