Look
Colour, retouching, cut-outs, picture-in-picture frames and motion. Most of it lives in the inspector when a clip is selected.

Colour
Grade
Inspector ▸ Grade has the sliders. With several clips selected, a slider sets that one setting on all of them.
Add a LUT
Use the LUT menu in the Grade section to pick a
.cubefile, then set its amount. Recent LUTs stay in the menu.Match shots
Select the shots, then . HTCUT measures both and nudges the grade of the others toward the reference.
Retouch skin
Inspector ▸ Skin: turn it on, pick a preset (subtle, natural, studio, max) and fine-tune smoothing, texture, tone, eye bags, wrinkles and neck. View mask shows what it touches. Faces are tracked in the background; the preview shows the clip untouched until that’s done, and export waits for it.
$ htcut grade --clip 6cefc281 --lut ~/LUTs/Film.cube --mix 0.6
$ htcut grade match --clip 5af63c3b --to 6cefc281
$ htcut skin --talking-heads --preset naturalCut-outs and masks
Pick a cut-out method
In Inspector ▸ Cut-out, each method fails in different ways, so switch until one holds:
- Subject and Person: Apple Vision, on your Mac
- Video: Robust Video Matting, steadier on hair; a small download the first time (Install)
- Points: Segment Anything 2 follows what you click, such as a product in a hand; about a 0.9 GB download
- Chroma and Luma keys, with an eyedropper for the key colour
Cut-outs are made in the background, only for the parts of a clip you use.
Keep only one person
Pick and Exclude let you click people or objects in the viewer to keep or drop them, and HTCUT follows your pick from frame to frame.
Tidy the edges
Edges: choke (shrink or grow), feather and invert, for every method.
Draw shape masks
Shapes: rectangles, ellipses, polygons and a brush. Each one adds, subtracts or acts as a garbage matte. Shapes stick to the footage, and a shape with keys follows it over time.
Frames and picture-in-picture
Inspector ▸ Frame turns a clip into an iPhone, iPad or MacBook screen, or a circle or rounded picture-in-picture with a border and shadow. The border uses your brand accent unless you pick a colour, and a fill colour or gradient can sit behind a cut-out.
$ htcut device --clip ca9d82a2 circle --border 0.03 --color "#0071E3" --scale 0.3 --x 700 --y 300Motion
- Speed: Inspector ▸ Speed for a constant speed or a ramp (hero, ramp up, ramp down, bullet). Pitch is kept. Smooth slow motion makes in-between frames for slow, constant speeds.
- Stabilise: Inspector ▸ Stabilise smooths handheld footage. At 1 it’s close to a tripod.
- Keyframes: Inspector ▸ Keyframes adds keys at the playhead. Diamonds on the clip drag to retime.
- Punch-ins: scales every other jump cut in on the face.
- Screen recordings: zooms to where things happen, and ⌥⌘Z zooms on the spot you click.
