Technical video preparation and stylisation on VapourSynth and FFmpeg. Twenty-eight presets across four independent palettes.

Why It Exists

VapourSynth does what no editing suite offers out of the box: restoring film material, deinterlacing with a good algorithm, denoising that treats the shadows separately, neural upscaling. But using it means writing a Python script, remembering plugin names, and assembling a pipeline by hand for every clip.

This program turns that into a set of ready presets. The script stays under the hood: the engine assembles a vspipe | ffmpeg chain and runs it.

Four Palettes

They are independent: you can take the technical processing alone and never touch the stylisation, or the reverse.

palette	presets	what it does
Precision	8	denoising, including shadow-targeted, debanding, controlled return of fine grain. The technical layer before the colourist
Film	7	film emulations: 35 mm Kodak, 16 mm, Super 8, bleach bypass, IMAX 70 mm, a general cinematic look
Retro	3	analogue character: VHS and CRT, a 1990s camcorder, Polaroid
Restoration	10	what editing suites lack: deinterlacing, inverse telecine, motion-compensated denoising, derainbow and deblocking, dehazing, plus neural upscaling and frame doubling

Order matters. The precision palette is the technical layer that comes before colour grading: fixing noise after the colourist has lifted the shadows is too late.

The Principle

The engine is a Python orchestrator over vspipe | ffmpeg. It neither rewrites VapourSynth nor hides it: the assembled command is visible, and you can take it and run it by hand.

The launchers are ordinary batch files with a quick picker and a fallback menu, in Russian and English versions.

Editions

edition	presets	difference
full	28	with the neural layer: upscaling, frame doubling, neural denoising
Lite	22	classic VapourSynth plugins, no neural stack

Lite is lighter and needs no graphics card for the heavy operations.

Technical Reference

Before the First Run

The VapourSynth engine and its plugins are installed separately — once. Until that is done, the presets will not run.

FFmpeg and the NVIDIA Driver

Every FFmpeg build is compiled against a particular version of the hardware-encoding headers and demands its own minimum driver. The newest build on an old driver does not accelerate anything — it breaks the hardware path. The build is chosen to match the driver.

Profiles

Saved combinations of presets and parameters — so the same chain need not be assembled twice.

CUDA

Needed only for the neural layer and only on NVIDIA cards. Setup is covered in the user guide as a separate section.
