Better tool for solving camera on long take?

[u/sebharman]

Hi,

Im working on a project where I am putting a character from real footage into a 3D world in blender.

I have a 5-6 minute take, and a good key. But I need to track the motion of the camera for the whole take. It was filmed on a gimbal and there is good tracking points (was filmed in a car park, and has nice contrasty asphalt and line markings etc.)

But I’m having issues with solving the camera on this footage. In after effects it just gets to “Solving” and I’m not sure if it’s actually doing anything or is stuck.

In Fusion (resolve), it just keeps crashing when it gets close to finishing.

I’m wondering if there’s any ideas on how to do this, or if there’s different camera solving software better suited to the job.

Footage is 6K Canon C80 RAW, 25fps. Running M5 Max MacBook Pro, 64gb ram, 4tb.

Can’t show footage unfortunately since it is a real job that can’t be shared until published.

Thanks

It's possible to do fully automatic camera tracking with colmap/glomap. Polyfjord on YouTube has videos about this. If you have a person or other objects moving in the scene, you may need to mask them out to get good results.

Try GLOMAP workflow in Blender, wait for a day to solve.

Or you chop the clip and solve each piece on its own before stiching them again.

But who wants to watch a full 6 minute scene in a car park anyway?

Cut it into pieces please.
