AI Long-Form Video Editor — Edit thirty-minute videos with AI-assisted cuts, filler-word removal and automatic chapter markers. Built for YouTube and courses.
What AI Long-Form Video Editor does
Long-Form Video Editor is designed for the format most AI tools ignore. Instead of working in seconds, it works in hours — transcribing the whole recording, removing filler words and dead air, suggesting cuts where the speaker resets a point, and generating chapter markers from topic changes. You keep editorial control; the tool removes the tedious part.
Key features
- Full-length transcription with a text-based editing surface
- Filler-word and dead-air removal with a single pass
- Chapter markers generated from topic changes
- Silence compression that respects natural pacing
- Audio repair for room noise, hum and uneven levels
- Chapter and thumbnail export for YouTube and course platforms
How it works
- Upload your recording and let it transcribe.
- Edit the transcript rather than the timeline — delete a sentence to delete the footage.
- Review the suggested chapter markers and rename them.
- Render the finished video with chapters attached.
Who it is for
YouTubers publishing long videos, course creators producing lessons at scale, and teams turning webinars and internal sessions into reusable content.
Why teams choose AI Long-Form Video Editor
Most AI video tools optimise for a single impressive demo. AI Long-Form Video Editor is built for repeatable output — the same settings produce the same quality on the hundredth export as on the first, and everything you create stays editable. That matters when a campaign needs twenty variants, when a client asks for one more revision, or when a series has to look consistent across a whole season of work.
It also fits into the rest of the OpenFilmo pipeline. Assets you create here can be finished with our other tools, and your brand kit carries through automatically so nothing leaves the studio off-brand. Commercial use is included on every paid plan, exports are watermark-free, and nothing you make is locked to a format you cannot change later. Start with a single render, or compare the plans on our pricing page.
Frequently asked questions about AI Long-Form Video Editor
How long can the source be?
Recordings up to four hours are supported in a single project.
Will removing filler words make speech sound choppy?
No. Cuts are placed with padding around them so the result sounds natural rather than clipped.
Can I edit by transcript?
Yes. Editing the text removes the corresponding footage, which is far faster than scrubbing a timeline.
Does it export chapters?
Yes. Chapters export in the format YouTube and most course platforms accept.
