The Foundary Tacker/Boujou/Mocha!?!?

Hi.

Could someone offer me advice on how to track the front end of the film camera in the clip below please? I have tried Boujou, The Foundry Camera Tracker and Mocha with absolutely no success.


Track clip




It's only a test shoot but I simply want to attach some text to the end as if it's sat in scene and firing out of the lens (I hope thats makes sense!?)
I'm surely clearly something very wrong but I just can't figure it out.

The footage is from a Canon 600d.

Many thanks

Stuart.

If you have AE CS6, you can try the new inbuilt 3D Camera Tracker. It gives pretty good results.

Hi.

Thanks for your suggestion but I'm still using 5.5 at the moment.

The Foundry 3D Tracker and Boujou both fail to recognise any usable track points on the camera at all. To me it seems like it should be relatively straightforward so I'm assuming it's something I'm missing/doing wrong rather than the Foundry plug in or Bojou, or a problem with the footage itself.

You dont want a camera tracker to track the front of the camera the talent is holding, you need a motion tracker like Mocha which is free in AE.

But you will need to learn how to use it. Its a powerful tool, but fairly complex.

You could try the regular tracker built into AE. That might be able to do it.

Ah ok, that makes sense.

The Foundry/Boujou for Match Move, Mocha for tracking an object etc.

I have tried Mocha but it didn't get anything useable though...Back to the tutorials!

Thanks

Once you get the basics of Mocha down, it should be an easy track.

I really think the regular Motion Tracker that has been a part of AE for many years would do a good job too.

Would the AE tracker be able to handle the perspective change?


Thanks again.

Yes with a 4 point track.

Mocha will probably be a better choice though now that I know you need perspective.

Thanks again for all the advice.

My only export options in Mocha are either Transform, which apparently doesn't include perpective data and Corner Pin, which dosn't seem like the righ thing to me...

I've attached 3 images below that should hopefully roughly demonstrate the type of thing I am trying to achieve.




Thanks!

Thanks Tom for correcting me.

Stuart

In Mocha, if you go to Track panel(below your Viewer) , you will notice that there are option for Transform,Rotation, Scale, Shear and Perspective.

Click on the Export Tracking Data button and copy the data from clip board. Then just paste it to a solid or a null object in AE by pressing " Cntl/Cmnd + V "

You also need to DELETE the ANCHOR POINT keyframes when you are using transform to track an Object.

Because of what you want the text to do, this is a very advanced track.
Mocha is a planar tracker. You really need to track data from the right side plane and then the left side plane of the camera for the text to animate in the manner you illustrate.

Just tracking the front plane of the camera lens wont have it do what you want I think.

Tom

Why 3D Camera Tracker is not usable here? I have seen some tutorials and there is an option for 3d Camera and Text in it which may help Stuart what he wants to achieve.

Here is the one I am talking about:

Vishesh, It conceivably could work since the only movement is the camera. I thought she was moving her arm as well. Only one way to find out, try them both and use which ever one gives the most satisfactory results. :D

Stuart, if you dont wont to waste time learning to use the wrong technique, send me the clip and I will tell you which one you will get the best results from.

Thanks so much guys.

Tom, I'd very much appreciate it if you could take a look at the clip for me. I think (as you point out) I'm just not quite sure which technique I need to use.

In the clip the talent is moving her arms a little (though certainly not excessively) so that could be the issue. However, I have since tried going back to basics by simply shooting a tabletop with a few high contrast markers on it and performed a similar camera move. My results are still unusable though, with the text sliding around a lot.

I've been trying all day to work it out and I'm about to go crazy!

I found your email address in your profile so if it's OK with you I'll email you the clip now.

Very much appreciated.

Stuart

Stuart I sent you an email with some observations. Also I sent the project back (tracked) by We Transfer. I hope you are on AE CS6 since that is what I used. See if you can replicate what I did so this becomes a learning experience. Good luck!

As it turns out , the solution that worked was using AE Camera tracker to track the shot, then manually tracking the motion of the person holding the camera. She did a little move in the middle of the shot.

Real life (and work) got in the way since the weekend but I'm hoping to give it a try tonight/tomorrow.

I'll let you know how I get on.

Stuart.
