Foundrys Camera Tracker
I have a strange happening (Bug?) with the camera tracker.
I have a quicktime movie to track. I set it up, solve, make scene, grab some points and make a null, parent my other element to the null, and ram preview. Everything is correct, and how I want it. BUT when I render it, the film doesnt play properly. The parented element moves with the correct tracking position, but the background film stutters and doesnt play right through. I pulled my hair out for a day trying heaps of things, precompimg etc, and eventually found out if I delete the Camera tracker effect after creating the scene, it will render correctly.
Anyone else had this?

That’s strange. What are your footage, comp, render and output module settings?

So the cg elements are ok through the clip, but not the live action movie.
How about pre-render /replace the original quicktime movie with a tiff sequence?
Then you can fire up your final composite render!
It might be a transcode error
Do u play with dslr H.264 ? -
Hi Roland, thanks for the reply.
Its a normal PAL 1050×576 film, with animation codec, lower feild first Quicktime.
With the Camera Tracker effect on, the background film doesnt render properly. When I turn it off, it renders correctly. -
Thanks for the reply.
It was originally a .mts file, shot full HD on a Panny AF-101, but in accordance with Dave LaRondes rule #1, I converted it down to a PAL Widescreen Quicktime, animation codec, before putting it into AE. Im trying to render it out in the same format. Like I said, Camera tracking effect on, background film has a shite render. Effect turned off, everything is ok. I mean its not the end of the world, and its an easy, simple workaround. I was just wondering if anyone else had experienced something similar… -
My approach is not to deal with any codec.
I’d recommend ( if i may ) u to work with dpx or tiff Sequences for read/write.
All you have to take care after this is a just a hard drive space / low cost nowadays!
But rendering as Seq. u will always have the option to resume render after a crash
and u’ll be able to check the rendered frames whilst rendering as well.
Once u happy just deliver it to the final file format. -
just my 2cents…
Have you tried to disable the motion blur?

I agree with Steve, render out your background plate (original footage) as an image sequence (full resolution,.tif, .psd, ,dpx, etc.) and use it in your main comp for tracking, compositing, etc. Output your final comp at full resolution (uncompressed if possible) and use that as a master for compression… make sense?
Thanks,
Shawn

why have you rendered it as lower field first?
I was always told the only codec that you should use that setting for in Pal is DV. Everything else should be Upper field first.
It could be that you are seeing an interlacing issue.Adam Taylor

It is PAL DV widescreen.

CamTracker can be a resource hog with long tracks. What sort of duration are we looking at here?
