Hello All,
Hoping someone can help me out here. I did an export to Carrara 5 Pro from the ' Uphill ' sequence after doing a fully automatic Track and alligning a co-ordinate system, 1st using the ' *3 ' method and using 3 trackers on the slope that looked like they defined the angle of the slope ok, on another attempt i used the manual allignment method from the web site tutorial section. In both cases i placed a Cone object in the scene about half way up the slope ( so i had a postion and a ref to allign a flat plane object against in carrara to use as a shadow catcher object for rendering etc ). While playing in Syntheyes the cone is rock solid against the background video clip and no sliding/ slipping is evident even on close inspection.
After opening carrara ( and setting the FPS to 24 to match the uphill clip before importing ) and importing the syntheyes file, i press play to preview or render the scene and the trackers and imported cone every so many frames is slipping / wiggling and i cant work out where i've gone wrong. I have done exactly the same process with the 'Flyover' sequence and some of my own DV clips and every thing looks solid as a rock. Has anyone got any ideas why i might be having this prob with this Clip ??

Any help would be greatfully appreciated

Paul

It's been years since I used Carrara and have never used it in combination with SE, but as an educated guess I'm thinking you might be dealing with a single frame offset issue. Your quickest way to check this would be to move the camera keyframes one frame earlier or later (try both - it would depend on whether Carrara wants to start on frame 0 or 1 and how your preferences are set in SynthEyes) and see if the problem resolves itself.

Contact me on email on theis. Offhand it sounds an awful lot like you don't really have the same frame rates for everything.
