Motion Tracking Issues
Hi I’m a university student working on a short film for a compositing module.
In the final shot of the movie there is a man throwing his head into a fish tank. The character needs two simple Fish Gills attached to each side of the neck, however this is my problem >-||
For previous shots we used corner pin track points which worked great but for this final shot we forgot to reapply them. Now due to the low light and underwater environment, I’m finding it extremely difficult to make a good track. I’ve experimented for days, used a number of different software’s, tried pre colouring the footage, even manually tracking but it’s just not working and I’m desperately running out of time.
I’ve posted the shot on a private Vimeo page the password is ‘gills’ and the link is below.
If someone knows any techniques that might help or maybe a way of disguising the area around his neck so I can remove the gills altogether then please let me know.
Many Thanks

I havent been able to see the videos since it says it´s password protected. Anyway I recommen you trying to do the tracking with mocha and then exporting to AE. I have shot crappy quality videos and tracked them with mocha with really great results.

Saw the video- yep, I see you sweating.
If what Dave suggested does not work (although it would be best), you may be able to track with Boujou or Syntheyes… but if you’re not familiar with those, it would take you longer than to re-shoot.
One other thing to try is to see if you can fake the neck- roto the face around his jaw with some feathering, take a still that reveals the neck, clean up cloning to fill in behind the jaw, add the gills and animate behind the face loosely matching the real movement. Or just re-shoot…;-)Tudor “Ted” Jelescu

Thanks for all your responses 🙂 I’d be happy to re-shoot however I found out our actor is out of the country and wont return until after my deadline.
Iv’e already spent hours experimented with Mocha & Bonjou but the result was still awful. However Iv’e never heard of Syntheyes so I might give that a go.
As for the fake neck approach, it’s not ideal but its worth considering, Ive already rotoscoped around the head in an attempt to simply color grad the neck but the thought of re-animating never occurred to me.
In the meantime any other suggestions would still be greatly appreciated 🙂
Thanks

And Dave, you know as well as the rest of us that the people who say that are NEVER the ones who sit in our chairs! 🙂
