What is a talking-head AI video
Show up daily. Without filming once.
A talking-head AI video features an AI character speaking your script with realistic lip-sync, expressions and a chosen voice. Use them for YouTube long-form, reviews, reactions, lessons or daily Shorts — without ever booking a studio.
Same face, every video
Train your AI character once. Use it across long-form, Shorts, ads and posts.
Multilingual lip-sync
Speak in any language with perfectly synced mouth movement.
Pick or clone a voice
Use any of 1,000+ pro voices, or clone your own in 30 seconds.
Long-form + Shorts
Render 16:9, 9:16 and 1:1 from the same character and script.
Why talking-head creators switch
Daily talking-head content. Zero filming.
The old YouTube way
Hate being on camera
Lighting, makeup, wardrobe, retakes. Some days you just don't want to film — and your schedule slips again.
Look tired in every Short
Daily filming wrecks your face. By Wednesday you look like you've seen things. Viewers notice.
Wardrobe consistency
Did you wear that shirt last Thursday too? Daily talking-head means daily outfit anxiety.
Stuck in one language
Your French viewers want a French version. You can't film yourself in French — and dubbing sounds fake.
With Postcrest
Same face, every video
Train your AI character once — yourself, or a designed persona. Use them on every long-form, Short, ad and post.
Look fresh every day
Your AI character never gets tired, never has a bad-hair day, never needs lighting fixes.
Outfit grammar, every video
Lock the wardrobe, brand colours and styling once. Postcrest keeps them consistent across every video.
29 languages, real lip-sync
Re-render your video in 29 languages with phoneme-accurate mouth movement — not dubbed-over fakery.
AI talking-head tooling
Every tool an AI talking-head channel needs.
AI character training, voice cloning, multilingual lip-sync, expressive gestures, B-roll cutaways and multi-format export — everything a daily talking-head YouTube creator needs, without ever sitting in front of a camera.
Clone yourself in 5 minutes
Upload 5–10 photos and a 30-second voice sample. Postcrest builds your AI twin — your face, your voice, your gestures.
Or design a persona
Don't want to use your own face? Build an AI character from scratch — features, age, ethnicity, body type, style.
Multilingual lip-sync
29 languages, phoneme-accurate mouth animation. Same character speaks each language fluently, with native prosody.
Voice cloning
Clone your real voice from 30 seconds of audio. Every talking video is in your voice — including the multilingual versions.
Long-form + Shorts + ads
Same character renders to 16:9 (long-form), 9:16 (Shorts) and 1:1 (ads). One trained character, every format.
Re-render on edits
Fix a typo, change a fact, update a stat — re-render in 1 minute. Used to mean a full re-shoot.
How to make an AI talking-head video
From a script to a talking-head video, in your face.
Four steps. Zero filming. Train your AI character once, drop in any script, render with phoneme-accurate lip-sync, then auto-export to 16:9, 9:16 and 1:1 in 29 languages.
01
Pick your model or character
Use a stock AI voice + faceless visuals, clone your voice, design an AI character or use one you've already trained.
02
Drop in your topic or script
Paste a title, an outline, a transcript or a finished script. Postcrest writes (or rewrites) it for YouTube's pacing.
03
Generate the post
Voiceover, visuals, captions, covers, thumbnails — all rendered in one batch in minutes.
04
Schedule & grow
Schedule to YouTube, generate variants and let Postcrest's AI engagement tools draft replies and grow your account.
How to make an AI talking-head video
Script in. Talking video out.
An end-to-end Postcrest run for a talking-head review channel.
Step 1 · Your input
"Have my AI character review the latest iPhone for 5 minutes."
Drop a script, a transcript or just a topic. Specify length and tone — Postcrest writes the rest.
Step 2 · Pick character + voice
Your AI twin or a designed persona
Choose from your trained characters and voices. Postcrest applies lip-sync, gestures and expressions to match the script.
Step 3 · Render with B-roll cutaways
Talking-head + product B-roll synced
Postcrest renders the talking head and intercuts with B-roll matched to each line of the script. Captions auto-included.
Step 4 · Multilingual + Shorts + publish
EN + FR + ES + JP + 9:16 cut, scheduled
Pick languages. Pick formats. Postcrest re-renders each. Schedule the whole bundle to YouTube + Shorts at once.
