Make a video
Paste your script. The title comes from the first line; a blank line starts a new paragraph, and a short line with no period becomes a chapter heading.
Your videos
Everything you have made. Carry on with the ones that stopped early.

Add a presenter
Already have a finished video — footage, edit and voice-over done elsewhere? Drop it here and one of your cast will present it. They lip-sync to the voice-over that is already in the file: nothing is re-voiced and the sound is left exactly as you mixed it.
Stays on this machine. The picture is rebuilt once, the sound is copied across untouched.
They come in where the voice-over pauses, opening and closing the video — the same rhythm as your own videos: about one appearance a minute and a seventh of the running time.
Scene editor
Change a scene here, then make just that scene again. Nothing is generated until you press a button.
Your cast
The people who can front a video. Each one needs a face HeyGen can drive and a voice. Nothing is generated until you press a button.
Bodycam
Each episode gets its own cast: faces, wardrobe passports and voices. Review them here before the expensive stages run — listen to a voice, change it, and the video will use your pick.
Setup
The keys the tool works with. They stay on the server — this page can put one in, but there is no way to read one back out, not even for you.
Signing in spends the credits in your HeyGen plan. An API key would bill per video instead — that is why this is a sign-in and not a key.
Both speak the same Claude API. Saved with the button above.
Applies to the next video started, not to one already running.
Nature and wide shots get their detail spread over the whole frame, so the normal setting turns brush and grass into mush. Close-ups, hands and screens are untouched — they look the same either way. Applies to every channel, from the next video started.
