I have a footage shot with a static camera (4K with a Pixel 2 XL front camera in case it is needed) on a tripod. I'd like to add a moving cube on fire to the scene.
As far as I understand (I'm completely new to compositing and VFX), I cannot rely on camera solving because the camera is static.
After extracting the first frame of my footage, I opened it with fspy and solved the perpective:
The image appears in the 3D view thanks to the Background images of the camera object data. Please note that it does not appear in the render.
I animated the cube and set a quick smoke simulation.
Now, how do I render the whole movie in eevee? in cycles?
Here is my blend file:
