Need help using camtrackar in unreal (examples?)
I'm trying to build a comp using CamTrackAR and unreal engine and am having problems. I was able to convert the CamTrackAR file to FBX using blender and also converted the video to a sequence of EXR images.
I was able to build a comp in unreal using composure, but something still seems to be wrong. The first frame seems aligned right but as the camera moves the comped character slides around a lot and doesn't seem to match with the shot footage. I am thinking maybe the image sequence and unreal CG aren't syncing up correctly, or possibly the camera parameters in unreal need to be changed/added to in order to get a good match with my ipad lens.
I'm wondering if anyone has an example of a comp done entirely in unreal, using an image sequence for the movie?
The other problem I'm having is that when I try to render out the comp in sequencer, it runs fine but after about 60 frames seems to slow way down even though the cpu, gpu, disk and memory use are very low. Again this seems to be a problem related to the image sequence as even during the rendering I'm not sure the sequence is in proper sync.
