360 Projection

360 Projection · screenshot coming soon

What this node does

This node runs FFmpeg’s v360 filter to convert between spherical/panoramic projection formats. Feed it a COMFYTV_VIDEO clip in one projection (say equirectangular 360 footage from a 360 camera) and it outputs the same footage remapped into another projection, optionally rotated by yaw/pitch/roll so you can pick which part of the sphere the “camera” looks at. It has a ▶ Run (FFmpeg does the reprojection). If input and output projections match and there is no rotation or FOV change, it passes the clip through untouched. Input and output are both COMFYTV_VIDEO. To hand the result to native ComfyUI nodes, insert a Bridge — see the bridge note.

​
When to use it

  • Extract a normal flat shot out of a 360 recording, aimed wherever you want with yaw/pitch/roll.
  • Make a “tiny planet” / stereographic look from equirectangular footage.
  • Convert between delivery formats (equirect ↔ cubemap-style EAC, fisheye, etc.).

​
Parameters

​
proj_in

The projection your source footage is already in. Options: equirect, flat, fisheye, dfisheye, sg, eac, ball, hammer, cylindrical, pannini, barrel. Default equirect (standard 360 monoscopic panorama).

​
proj_out

The projection to convert to. Same option list as above. Default flat (a normal rectilinear shot). sg (stereographic) gives the little-planet look.

​
v360_yaw / v360_pitch / v360_roll

Rotate the virtual camera on the sphere before reprojecting, in degrees, each from -180 to 180 (default 0). Yaw pans left/right, pitch tilts up/down, roll rotates the horizon. Use these to aim a flat output at a specific part of a 360 scene.

​
v360_fov

Output horizontal field of view in degrees, 0 to 360 (default 0 = filter’s default FOV for the chosen output). When non-zero, the vertical FOV is derived at a 16:9 ratio automatically.

​
v360_interp

Resampling quality when remapping pixels: linear, cubic, lanczos, nearest. Default cubic — a good speed/quality balance. Use lanczos for the sharpest result, nearest only for masks/hard edges.

Tips

  • For the classic tiny-planet effect: proj_in = equirect, proj_out = sg.
  • flat output is your friend for pulling a usable shot out of 360 footage; aim it with yaw/pitch.
  • Bump v360_interp to lanczos if reprojected edges look soft; drop to nearest if you must preserve a hard mask.
  • 360 Stabilize — smooth out camera shake in 360 footage before or after reprojecting.
  • Lens Distort — for ordinary (non-360) lens undistort/distort work.
