Default Look

When you run hance video.mp4 without --preset, hance loads the built-in default look. This is a balanced cinematic starting point, not a neutral pass-through.

What the default look does

Effect	Setting	What it does
Color	All neutral	No color shift: exposure 0, contrast 1, white balance 6500K
Halation	0.25 amount, radius 4	Subtle warm glow around highlights
Chromatic aberration	0.3	Slight color fringing at edges
Bloom	0.25 amount, radius 10	Gentle light diffusion
Grain	0.125 amount	Light organic noise
Vignette	0.25 amount, 0.25 size	Mild edge darkening
Split tone	0 amount	Disabled (amount is zero)
Camera shake	0.25 amount, 0.5 rate	Subtle handheld motion

The default look is not “no effect”

Even with neutral color settings, the optical effects (halation, aberration, bloom, grain, vignette, camera shake) are all active. To get a clean pass-through, disable them:

hance video.mp4 --no-halation --no-aberration --no-bloom --no-grain --no-vignette --no-camera-shake

Overriding the default

Any preset you choose replaces the default as the base. CLI flags then override on top:

# portra-400 as base, with extra grain
hance video.mp4 --preset portra-400 --grain-amount 0.3
