Video VFX Vignette
video-vfx-vignette
Applies a radial corner-darkening effect to focus the eye on the center of the frame.
video-vfx-vignette accepts an integer from 0 to 100. 0 is off (default). Higher values darken the frame corners progressively toward black. Out-of-range or non-numeric values are coerced to 0 rather than rejected.
| Value | Effect |
|---|---|
0 | Off (default) |
30 – 60 | Subtle cinematic frame; natural focus pull |
80 – 100 | Overt vintage frame; edges fall to black |
The vignette uses a radial falloff (vignette_cuda, a faithful GPU port of FFmpeg’s vignette filter), so its darkening curve matches the well-understood reference.
The vignette is the last effect in the VFX compose order (chromatic aberration → film grain → bloom → halation → vignette), so it frames the finished composite — darkening everything including any grain or glow applied before it.
Overlays (watermarks, PiP, captions) composite on top of the vignette and remain unaffected.
