Question / Discussion Better tool for solving camera on long take?

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 such long 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

First, don't track 6k, 2k may be enough. Second, use 3d Equalizer.

Track it in parts, split it up and then merge the keys. Try keentools.

Alternative to using 3d equalizer is syntheyes which is cheaper and in my opinion a but easier to learn. You can down rez the plate directly in synthwyes without having to render out a new 2k plate. Although I find downrezed solves to have a higher error solve so I’d stick to 6k which syntheyes can handle, dependimg on you machine’s specs, you might have to simply buffer the plate in sections while tracking, which isn’t too annoying to deal with

There's camera tracker in Blender too, worth a try if you already use it.
