Hi folks,
Imagine this:
Please check the youtube film below.
It's me filming my sofa on my crappy Huawai smartphone.
This is just an experiment, i wouldn't actually want to do this!
Ok, so, what i want to do if recreate this scene in 3D space so i can blend elements of the real scene (perhaps i had someone sitting on the sofa?) with 3D stuff.
I have the measurements of the sofa (length 218cm, height 63cm, Depth 98cm).
Now, in my naïve mind, i imagine the following should be possible:
- I create a box in 3D with the same proportions.
- I position my camera so it matches the first frame.
- I do the same for the other frames (maybe not every frame, that would be a lot of work, maybe once every 3 frames then smooth the camera movement curves in between).
- Now i have recreated the scene in 3D. And because i have done it carefully, everything else in these two "worlds" should also match up.
Easy in theory, but in practice it doesn't work. My Huawai phone has a crap lens with lots of distortion, so it's never gonna match up in my recreation
But even with a good camera (i have a sony A7) i think it'll be the same.
So i'm wondering, is this something even possible in Fusion. Or is this more like high-end Hollywood type stuff and i'm being over-ambitious?
This is really complicated, right? Getting a 3D VFX camera to have the some properties as a real camera?
And lastly, is this in fact the wrong way to do this and is it more a job for tracking?
My suspicion is that in high-end (Hollywood level compositing) they wouldn't use tracking to blend a real and VFX scene together, they'd do something more on the lines of my idea.
I'm not looking for "do XYZ" replies, just some general thoughts!
If this isn't do-able in Fusion, any ideas what software is better for it?
Thanks!
