FAQ

Questions from founders and startup teams

Do founders need a video editor to make content?

No. You are building the product, not running a content team. Submagic runs Auto-Edit on a demo or update you record, adding captions, b-roll and auto-zoom and trimming the dead air, so you get a founder clip ready to post. There is no editor to hire and no timeline to learn.

Is there a free way to make founder videos?

Yes. Submagic gives you 15 free videos to start, so you can upload a demo or a build-in-public update, run Auto-Edit and add captions before you pick a plan. It is enough to see what a rough founder recording looks like once it is captioned and cut.

What is the best video editor for a startup founder?

One built for founders who would rather ship product than edit video. Submagic captions, edits and formats the demos and updates you already record, instead of asking you to learn a desktop editor. When you do not want to film, it can generate a faceless founder video from a script.

Can I make founder videos without being on camera?

Yes. AI Avatar turns a script into a video presented by an AI actor, so you never have to film yourself. Pick an actor and a voice, paste a short script, and you get a faceless founder video for a launch note or a product update, with no camera setup.

How do I keep posting build-in-public updates without filming every day?

Record a quick demo or screen capture when you ship something, and let Auto-Edit caption and cut it into a clip. For the weeks you cannot film, AI Avatar turns a written update into a faceless video, so your build-in-public cadence does not depend on being camera-ready.

How do I turn a product demo into a clip I can post?

Upload the screen-and-talk recording of your demo, and Submagic auto-edits it: it captions every line, adds b-roll, auto-zooms and trims the dead air. You get a clean, captioned demo clip for LinkedIn, YouTube or Reels, made from footage you already recorded.
