ElementForge — Transparent VFX Elements

Generate fire, smoke & FX as transparent RGBA elements.

Describe an effect — we generate it on black and key it to a clean premultiplied alpha. Download a Nuke-native RGBA EXR sequence, a ProRes 4444 with alpha, or a 16-bit PNG sequence, and composite it over your own footage at any resolution. No plate needed. Sister tool to the EXR Shot Editor.

1. Describe the element

Element type

Prompt (optional — refines the look)

Isolate from YOUR footage (optional — public video URL)

V2V mode: describe what to keep above (e.g. "the burning man and his flames"); we isolate it on black → shot-matched element.

Resolution

Duration (s)

Pick a type and hit generate.

2. Preview & download

The element (over a checkerboard, so you can see the transparency) appears here.

Composite an effect onto your RAW plate (EXR) — frame-exact, plate untouched

Upload your plate sequence (EXR / DPX / PNG as a .tar or .zip). We generate the effect on black and composite it onto your untouched plate — same resolution, same float bit depth, exact frame count. You get back the composite, an effect-only RGBA matte (a plain Nuke/Fusion "over" of it on your plate rebuilds the comp), and a 720p preview. Your plate never passes through the model.

Effect

Plate sequence (.tar / .zip of EXR / DPX / PNG)

Subject roto for tracking (optional — .tar/.zip of mask PNGs)

No roto? Leave blank — the effect is placed on the lower-centre subject. (SAM2 auto-track runs when a GPU is free.)

Effect scale (×body)

FPS

Ignite (frames)

Upload a plate and composite.

The 720p composite preview appears here once ready.
