FBX Export Without Camera Keyframes
Hi,
I've tracked a shot in PFTrack and need to export the result as an FBX to open in C4D.
The shot starts at frame 1955497 and ends at 1955582.
When I use the Scene Export node, the FBX exports without any problems. However, when I open the file, the only camera keyframe is at F0.
The trackers export correctly.
I’ve tried adjusting the Frame Offset in both the Scene Export node and C4D, but the camera keyframes still don’t appear.
Any idea what might be causing this?

Hello Henrique, welcome to the community!
It could be you’re running into a frame-time mismatch between PFTrack and Cinema 4D. The FBX format is time-based, meaning it relies on the frame rate to correctly convert frame numbers into time values during export and import. If PFTrack and C4D are using different frame rates, your camera keyframes might end up in the wrong place.
Here are some things you can do:
Check that both applications use the same frame rate. Make sure your PFTrack project and C4D scene are set to identical FPS values.
Inspect the scene attributes window in C4D. After importing the FBX, open the Scene Attributes and look at the Time Min/Max and Preview Min/Max fields to confirm the frame range matches your shot.
Set the correct frame offset before export. If you want your exported FBX to start at time = 0, set the frame offset in PFTrack to the negative of your first frame number (for example, if your shot starts at frame 1001, set the offset to -1001).
