I've recently started using boujou for 3d traCking and have been experiencing an issue when importing into after effects. For some reason the tracked composition is a different resolution/aspect ratio from what the footage originally was. Any idea what the issue may be?

Hey Kavon,
Boujou's tough to get support for because it's so pricy. From what I understand it works like most other Matchmoving softwares.

Matchmoving is a process of giving the software hints as to where the camera/object(s) are in 3D Space. The more information you give the software the more accurate the track will be.

You should be able to setup your camera and lens before tracking in Boujou. It also means you'll likely have to re-solve the shot after changing these settings but you'll have a much easier time solving.

It can look very convincing in the matchmoving software with the wrong lens when you're looking at just points. You'll want to place test objects around the scene to make sure your track is solid. Also, look at the solved tracks, if they are progressively slipping as they get closer to the edge of the frame then your lens could be way off.

Setting the scale of your scene will help once you're in After Effects. At least make sure it's not ridiculously small/large.

Check your settings when exporting; make sure all aspect ratio settings (if any) are properly filled. You should have a scale setting here too.

Good luck,
