Long video in, short clips out
Short clips from an interview or webinar
Before you start: MomentCut works from the video file (MP4, MOV or WebM, up to 60 minutes), uploaded from your device (up to 30 GB, 20 GB on the free trial) or through a direct link to that file (up to 2 GB). YouTube, Vimeo or other platform links are not accepted.
An hour-long webinar is watched once, by the people who showed up that day. Cut into pieces, it feeds weeks of posts, landing pages and answers to customer questions.

What actually works in a long recording
The best moments in a webinar are almost never in the introduction. They are in the answers to questions, in objections handled well, in worked examples with numbers, and in the moments where the speaker says something they had not planned to say.
MomentCut reads the transcript and scores passages on how well they stand alone. You can steer the search by naming the topics you care about before running the analysis.
Coaches, trainers, consultants: show, rather than claim
A landing page says you are good. A forty-second clip in which you solve a specific problem demonstrates it, and lets the prospect judge for themselves. The clips that convert are rarely the broadest ones: an answer to a concrete objection, a method laid out in three steps, a common mistake described precisely.
You do not have to be on camera, but in advisory work it helps: the client is choosing you, not only the method.
Two uses, two edits
For social, you want vertical, captioned, short, and a hook in the first second. For a landing page or a customer email, a slightly longer horizontal excerpt, kept in context, will be more persuasive.
The same recording serves both: you choose framing and length clip by clip, without going back to the source file each time.
Recordings with several speakers
Wide-shot interviews create a reframing problem: two people in a horizontal frame do not fit a vertical one. Depending on the passage, you can follow the speaking face or keep the whole image. For a panel, the second is usually more readable.
As soon as an identifiable person appears or speaks in a clip, you need their permission to publish it, whether it is a guest, a client in a session or an attendee asking a question. Ask at recording time, not afterwards.
Mining the archive
Most organisations have years of recordings nobody mentions any more. That is not stale content: it is content that was never distributed. Revisiting an interview from two years ago costs one analysis, and is often worth more than shooting something new.

- Course modules you have already recorded
- Conference talks and guest podcast appearances
- Sample consultations, with the consent of everyone filmed
Step by step: cut an interview or a webinar
Upload the recording
On “Your video”, click “Choose a video” or paste a direct link to the file (.mp4, .webm or .mov). The limit is 60 minutes and 30 GB per uploaded file (20 GB on the free trial, 2 GB through a direct link): for a two-hour webinar, export it in two parts from your video call tool.
Point the search
In “Settings”, fill in “Topics to focus on” with the themes you expect (an objection, a method, a figure). The “Describe the moment to find” field targets a specific scene, such as the screen demo or the answer to an audience question.
Pick the format for the use
For social media, keep 9:16 and turn on “Face tracking” for the clip, picking the person to follow. For a sales page or an email, choose 16:9 or 1:1 and “Fit entire frame”, which keeps both speakers and the shared screen.
Run the analysis and sort
Click “Next: find my clips”. In “Results”, read the reason given for each clip and its “AI score”. In a webinar the best moments are often in the Q&A: check the clips from the second half.
Adjust each clip
Fix the edges with “Start (seconds)” and “End (seconds)”, rework the “Suggested title”, then check the speakers’ names in “Edit subtitles”. The “Ask for a change” box takes a written instruction, such as cutting the first three seconds.
Export
Click “Create video file” for each clip you keep. The file can be downloaded for 7 days; the project stays in “My projects” for more exports.
Recommended settings
- Interview shot wide: 9:16 and “Face tracking” on the interviewee.
- Webinar with a shared screen: 16:9 or 1:1 and “Fit entire frame”, so the slides stay readable.
- Target length: 1 min 30 for a reasoned answer, 30 seconds for a strong line.
- “Remove silences” tightens hesitant exchanges; if more than 40% of the clip would go, the clip stays whole.
- For a clip going on a sales page, untick “Show the title” if the page already has its own heading.
Limits and good practice
- Files up to 30 GB (20 GB on the free trial) and 60 minutes, in MP4, MOV or WebM; links to a video platform page are not accepted, only a direct link to the file (up to 2 GB).
- Minutes are counted on the length of the recording, not on the number of clips you get.
- Face tracking runs in the browser, on the selected clip: desktop Chrome or Edge is recommended.
- Free plan: 15 minutes once, 3 exports, watermark. A one-hour webinar therefore needs a paid plan or a minute pack.
- Before publishing, get consent from anyone identifiable on screen.

Common questions
How long can the source video be?
Long recordings are supported. Quotas are counted on the length of the source video rather than the number of clips produced, and re-running an analysis on the same project does not count twice.
Can I export without vertical reframing?
Yes. You can keep the whole frame instead of cropping, which suits excerpts destined for a website or an email.
Are my clips public?
No. Your projects and exports stay tied to your account, and nothing is published on your behalf.
How often should I post?
Two or three posts a week sustained over months beats an intense burst followed by silence. Consistency counts for more than volume.
