How I can distort image(movie clip) from rectangle coords to polar? Maybe I can do it in Node Editor or whatever? I need to replace pixels from XY to Angle R. But how I can do it? Thank you.
You can try using a texture node to perform a uv distort on the image by applying the blend texture radial. otherwise you would have to distort the real uv unwrap or possibly use a modifier to distort a mapped mesh in 3d view.
EDIT: So I imported this plane into Blender as Add > Mesh > Images As Planes Then add an empty and clear the location of both "alt G" Select the image plane and add 2 modifiers. 1. Subsurf, use simple, increase divisions to 6 2. Add a simple Deform modifier set to Bend. 3. Set Origin as Empty, then enter Deform Angle as 360 deg. 4. alter empty location if required.
