The Importance of On Set Reference, getting it and using it.
Hello sorry to take up your time, I’m Sean and up until quite recently I worked at the CG Coal face but now I have gone off to the world of research and that is why I’m posting here. Im looking at the area of On Set Reference use and capture
I know how it feels when a client comes in with a projects shot list and its time to work out costs and man hours needed per shot. Your team comes in and you talk throw the “how” it can be done shot buy shot.
Then some one says we need On Set Reference
It Could be
2D Image ref for Back Plates, Lighting Ref, HDR. Color or just over view ref etc
3D LIDAR, laser scanning, Photogrammetric ref, Total station Survey, Disto, GPS etc
Film/video Winners Cams, Videogrammetric ref, Basic MoCap
Camera Ref, Lens Grids, lens info (to shot number) Hot Head Camera mount etc
Mach moving/tracking targets, event targets, set extension/Blue Screen targets etc
You make a note of what’s needed and then you start to work out how to get it and what is needed, (no two CG VFX pipelines are the same so getting it into your current CG VFX pipeline also needs to be checked)
Then comes the part where the post house VFX Producer negotiates with the VFX Supervisor and production to get the data, could be some one from the post house go’s to set, could be production has a Data wrangler who’s over seeing the job or It could be a 3ed party hired in by production or the post house to get the data.
The data comes and you plug It into your pipeline and away you go, shots done well and high praise.
From my own experience I know its never that simple, A film/Tv Production From my own experience I know that a film/Tv set is as close as one can get to an organized train crash.
Most of use has come across an apophrycal story of some VFX post person being booted of set for getting in the way. Now it not always that bad but there are problems.
Moved. Lost targets,
miss named cans,
mixed up lens ref,
no time to get data,
set rebuilt of changed and many more.
Also problems can come when the data is comes
Files are just to big / off file format
Set areas missing,
And many more.
Then the post team starts to use it in your pipeline and more possible problems, Film plate dos not mach ref data. It’s the wrong kind, it was taken badly etc.
And that’s what this post is about, I would ask that no names be used if they are to be shown in a negative light. Just instances are fine.
What I’m looking for from the grate and wise minds of VFX Talk is
Instances, Ideas and observations on the good and bad of On Set References
Thank you so much for your time
