The finishing engine for long-form AI video
FilmWeld welds your AI-generated clips, voiceover and score into a paced, captioned, mixed episode — driven by a single script. Built for long-form storytelling, not 15-second clips.
The gap nobody fills
Every generator stops at the clip — and every editing tool is built for short social cuts. The hard part for long-form creators, assembling dozens of shots into a paced, watchable episode, still lands on you. That's the work FilmWeld takes off your plate.
How it works
Two stages do the work a whole edit suite used to. You only ever write the script.
Acts, beats and the lines spoken. Plain text — the way you already think about an episode.
Turns your spec into a paced edit plan: shot durations, mid-roll placement and synced caption cues. The editorial judgment of a long-form editor, automated.
Pulls your assets, retimes, burns captions, mixes audio and encodes a finished 1080p episode — in one pass.
What's inside
Shot lengths weighted by role — cold opens linger, b-roll moves — tuned to a target runtime, not a 30-second ceiling.
Caption cues generated from your script and timed across the whole episode. No manual subtitle grind.
Voiceover and score balanced and laid under the full cut. Any input format normalized automatically.
Runtime and breaks placed to keep monetization intact — built for how long-form platforms actually pay.
Provider-agnostic. Use the cinematic clips you generated — no stock libraries, no template look, no saturation.
Script in, finished episode out. Repeatable, consistent, and fast enough to ship a series on schedule.
Why it's different
The popular AI editors are built to chop long videos into short clips, or stitch stock templates into lookalike posts. None of them finishes long-form, narrative video made from your own generated footage. FilmWeld packages the editorial judgment of assembling a real episode — pacing, mid-roll, a consistent title and card system — into software. No credit traps, no template sameness. Just your story, welded into one watchable cut.
