Take finished FunscriptForge clips — video plus every funscript channel — and concatenate them into one long combined output. MP4 with chapter markers, channel funscripts in lockstep, fade-to-black joiners, per-section overlays, and a heatmap alongside the video.

Pre-release software. Provided as-is, without warranty of any kind. Use at your own risk.
Everything you need to take a folder of clips from pile-of-files to one polished output.
Group clips into sections that become MP4 chapters. Each section can have its own overlays, audio bed, joiner, and funscript channels — or share them with neighbours.
Drop a logo on the corner, a music bed across a section, or a title-card text block on the nine-position grid — with timing, fades, opacity, and per-overlay Mix % for audio.
Decoupled hold and fade between sections. Film-style transitions with configurable black-hold duration, per-side fade length, and a closing fade at the end of the output.
Concatenate main, multi-axis, three-phase estim, prostate — every channel your clips declare. Detects channel sub-folders for FunscriptForge layouts, stitches gaps cleanly.
One chapter per section in the MP4 — readable by VLC, File Explorer, Plex. A full-output heatmap of the main funscript track lands alongside the video for instant pacing review.
Runs on your machine. No cloud, no account, no telemetry. Your clips and funscripts never leave your computer.
A four-step pipeline from folder of clips to polished output.
Browse a folder or paste paths. Clips go into a single section, separate sections, or append onto the last section — your call.
Name each section for its MP4 chapter title. Pick joiners (cut or fade-to-black) between sections.
Drop an image logo, an audio bed, or a title-card text block on any section with timing, position, and fade controls.
Click Forge. The app concatenates the video, stitches every funscript channel, renders the heatmap, and writes chapter markers — all in one pass.
