The Effects page (under Produce → Effects) is a data-driven gallery of compositing effects. Pick a tile, choose the clip it runs on, tune a few options, and the result lands in your Library. Every effect is built on the same validated FFmpeg/OpenCV engine, so results are consistent and fast.
Gating: Pro (vfx) for the engine effects · Agency · AI (vfx_ai) for AI-segmentation · Agency · Tracking (vfx_tracking) for motion tracking. Locked tiles stay visible (dimmed) with an upgrade link.
  • Browse by category, or search to filter across labels, descriptions, and categories.
  • Sample previews — each card shows a poster of the effect; hover (on desktop) to play a short looping sample. Removal effects (background/chroma/object) show a before → after.
  • Rearrange — switch to My layout to drag cards into any order you like (and hide ones you never use). Your arrangement is saved to your account and restored on every device.
  • Run — click Run effect, choose the input clip (and a second clip / mask where needed), set options, and go. Save as composition to keep a recipe for reuse.

Background removal & keying

Remove background (AI)

AI matting — cut the subject out of a photo or video with no green screen. Output a transparent cutout (alpha WebM / ProRes 4444 / PNG) or composite onto a new background.

Remove background (green screen)

Chroma key with despill (green or blue). Export a transparent clip (WebM/VP9 or ProRes 4444) or composite over a backdrop. Free, in-engine — no credits.
Alpha export carries real transparency: WebM/VP9 (yuva420p) for the web, ProRes 4444 (yuva444p10le) for editing, PNG for stills. MP4 cannot carry alpha and is rejected on purpose.

  • Stylize — Light leak, Film grain.
  • Time — Speed change, Motion blur, Punch-in zoom, Vignette.
  • Glitch — RGB split, VHS / glitch, Mirror, Kaleidoscope.
  • Colour — Cold tint, Warm tint, Black & white.

AI segmentation (Agency · AI)

Text behind subject

Place a caption between the subject and the background — the words read as printed on the wall behind the person. AI matting, no green screen.

Replace background / sky

Matte the subject and drop in a new background or sky (image or video).

Remove object / person

Draw a mask over what to erase; it’s reconstructed in-engine (cv2 inpaint, no credits). An operator-configured provider model gives higher quality on large regions.

​
Motion tracking (Agency · Tracking)

  • Analyze motion — point or planar (region) tracking with OpenCV → a reusable track artifact.
  • Tracked overlay — pin a logo, label, or element to a moving point so it follows the subject.
Tracking is pure OpenCV — no provider, always available. A saved track also drives per-frame roto.

​
Roto (mask-driven)

Draw a mask in the editor, then:
  • Clone (overlapping) — show a second pass of the subject only inside the mask — the crossing / overlapping clone trick.
  • Portal (split) — reveal a second clip through a drawn portal region while the base fills the rest.
Both are in-engine (no credits) and can animate the mask along a track for moving shots.

​
Compositions editor

Save any effect as a composition, then open the editor to:
  • Layers — stack clips/elements with blend mode, opacity, and time range (reorderable).
  • Mask — draw polygon / ellipse masks with feather; the mask drives roto and object removal.
  • Reuse — load, rename, duplicate, or delete saved compositions as templates.
Composite, roto, and tracked effects ask for a second clip, a mask, or an overlay right in the Run dialog — the picker is type-aware (it shows tracks only where a track is expected).

​
Over the API

Everything is scriptable. Presets list via GET /vfx/presets; run any preset with POST /vfx/render ({ preset_key, params, inputs }). Dedicated endpoints exist for background-remove, chroma-key, text-behind, background-replace, object-remove, roto-composite, track, and tracked-overlay (public twins under /v1/vfx/*, scope jobs:create + the matching entitlement). See the API Reference tab.
