How do I make a fake livestream video with AI?
Generate an opening frame of your character with her phone at arm's length or propped on a table, then animate it with a video model using one camera line (one take, no cuts), a timed script with quoted lines and a few room sounds. Post it as what it is, a recorded AI short in livestream style with the AI label on, not as a real broadcast.
What "fake" should mean here
The livestream look is a storytelling format, like found footage in film. It is fine to borrow it for a fictional character. It is not fine to make viewers believe a real event is happening live. Keep the character invented, the setting obviously fictional, and the AI label on. TikTok requires labels on realistic AI content[1] and bans AI content that fakes authoritative sources or crisis events even when labelled[1]. YouTube requires disclosure of a realistic scene that did not occur[2]. In the EU, the AI Act's deepfake rule for creative and fictional works is limited to disclosing the AI content in a way that does not spoil the work[4].
Step by step
- Fix the character. One master image and one written description (face, hair, outfit, voice, attitude). Reuse both every time.
- Paint the opening frame from the phone's point of view: eye level, the character mid-sentence, the room behind her. The video starts from this frame, so the camera position is locked in.
- Write the camera line. This is the single most important sentence; see the prompt below.
- Write five beats for 30 seconds, or two or three for 15 seconds. Each beat gets a time range, one action, one quoted line and one sound. Open with a line that names the format ("Reading my hate mail. Live.") and end on a turn.
- Add sound: three to five room sounds. Models with native audio render dialogue and sound in one pass.
- Add the avoid list, render one take, and fix the prompt rather than batching spares if it is wrong.
The camera line and avoid list
One uninterrupted take in continuous time through the front camera of the phone propped still on the table, eye level, the only viewpoint, no cuts, no camera movement. Avoid: No subtitles. No background music. No streaming-interface overlays, phone filters, or masks. No phone body or hand holding a phone in frame or in reflections. No change to her face.
For a walking room tour, swap in "the phone she holds at arm's length, gentle handheld movement". The avoid list matters: ask for a phone-camera look and the model may paint a phone case into the foreground or invent a fake streaming bar. Full worked prompts are in the prompt library, and our AI livestream video guide walks through a complete 30-second script.
What the character should say
- Talk to the chat, not to the room: "Okay, you asked for it." "Someone in the comments said…"
- Answer an imagined comment out loud instead of showing a chat. It feels live without an overlay.
- Keep each line short enough to say inside its beat. Quoted lines came out lip-synced in our Seedance 2.5 renders.
- End with a reaction, not a sign-off: she gets caught, softens, or something goes wrong.
Our hate mail and love potion clips follow this recipe. Both were first posted with a chat overlay added in editing, which we have since dropped; see should AI livestream videos have a chat overlay.
Where Cast fits
- The Selfie / Live camera adds the one-take phone-POV instruction, so you only type the idea in one line.
- Free first try: a 5-second video with no sign-up, using the Malfoid & Friends pack.
- Up to 3 characters, for a friend walking into the stream.
Where it does not:
- 30-second single takes: Cast clips are 5, 10 and 15 seconds, so plan two or three beats.
- Adding a chat overlay or viewer counter: Cast outputs the clean video only.
- An actual live broadcast: Cast does not stream in real time.
People also ask
- Is it allowed to post a fake livestream video?
- The TikTok and YouTube rules we read ask for a label on realistic AI content rather than banning a fictional livestream-style short[1][2]. Presenting it as a real live event, faking news or crises, or using a real person's likeness without permission is not[1].
- What camera setup should the prompt describe?
- A phone that exists in the scene: propped on a table at eye level, or held at arm's length. Add "the only viewpoint, no cuts" so the model does not invent other angles.
- How do I write the script?
- Five timed beats for 30 seconds, each with one action, one quoted line and one sound. Open by naming the format and end on a turn. Ideas are in AI livestream video ideas.
