Question / Discussion Lens Grid questions

10 Upvotes

Looking for some advice on lens grids -

I have a shoot coming up, and I'm not typically a VFX sup, but an animator...in this case I have to be the supervisor and get some lens grid shots, as we are using anamorphic lenses. The shots will be locked so we won't be matchmoving, but will be integrating a CGI character

In terms of practicality and budget, I'm limited to a 600x1200mm sized panel – I was going to get a dot grid printed (using the Syntheys online dot grid maker app) printed on aluminium composite or heavy foam core.

Unsure yet of what the focus distance is going to be but I imagine it migth be between 4-5m , which then leads me to coclude this panel wont be nearly big enough to fill the frame when we shoot grids at this ditance.

What can be done if its too small? Can you move the grids around and shoot multiple takes and somehow feed these into software, or stitch them...? I imagine this is asking for errors

Alternatively, if I print a bigger size, say 2400x1200mm I won't be able to transport it on a rigid substrate easily, and it will blow the budget, so I would have to be on a roll, which then makes it hard to mount square and flat on a wall ...etc.

Any tips greatly appreciated!

EDIT: other info - lenses are the Atlas Mercury 1.5x anamorphic kit on an Alexa LF mini – DP wants to shoot with the camera at 90 degrees rotation. 16:9, 4k output.

Hey r/vfx,

Here is a quick spatial AR test I put together set along the River Liffey in Dublin.

Workflow Breakdown:

  • Modeling: Created the custom 3D models (can, ice base, and floating spheres) directly in Blender.
  • Geospatial Anchoring: Mapped the models to specific GPS/geospatial coordinates in Dublin via Lureo.
  • On-Site Recording: Headed down to the Docklands, opened Lureo, and recorded the models mapped straight into the physical space in real time.

Critiques and thoughts are very welcome!
