A talking head video from one photo
An AI talking head generator turns one clear photo and a script into a video of that face speaking, with the mouth driven by the audio. On Percify a talking video is 2 credits a second on the fast model at 480p, so a 20 second clip is 40 credits, about twenty seconds is the length to write for, and the photo decides quality more than any setting. No camera, no studio, no filming step.
- 2
- credits a second, fast model at 480p
- 40
- credits, a 20 second fast clip
- 6
- credits a second at 720p
- 20 s
- a good length for one idea
Credits cost about 2 cents each depending on the plan, so a minute of talking video at 120 credits works out at roughly $2 to $3.
What you give it, and what comes back
Two inputs: a photo of a face and the words you want said. It returns a video of that face saying them, with the mouth driven by the audio rather than animated by hand. There is no rig and no capture session.
The voice is either one of 52 preset voices or your own cloned voice, built from a sample of at least 5.6 seconds. Because the model conditions on the photo, most of the quality is decided before you press generate.
The length people actually publish
Every guide to talking head video recommends a two minute case study. For most uses that is too long.
Write for twenty seconds. A spokesperson clip earns its place as a hook, an answer or an intro, and all three are short. If the script will not fit, cut it into two clips rather than rendering one long one.
What it costs, and why resolution is the bill
Rendering is priced per second of output, and resolution changes the bill more than anything else you choose. 720p is 6 credits a second, three times the fast 480p rate of 2, for the same script. The case for 720p is a close up watched full screen; the case against it is almost everything made for social.
It is one credit meter across images, voices and video. There is no watermark on talking videos on any plan and no speed tier to buy. The full breakdown is in what an AI avatar video costs.
| Setting | Credits a second | 20 second clip |
|---|---|---|
| Fast, 480p (app or Playground) | 2 | 40 |
| High quality in the app, 480p | 4 | 80 |
| InfiniteTalk in the Playground, 480p | 3 | 60 |
| 720p (app or Playground) | 6 | 120 |
How long you will wait
Render time grows with the length of the clip and with resolution. A short clip at 480p is usually ready in a few minutes; a long one at 720p can take much longer. Queue it and do something else.
Choosing a talking head generator
Talking head tools come in three designs, and the design predicts results better than any feature list. Photo driven tools work from a single image of you. Video driven tools preserve a performance you already filmed. Stock presenters give the most consistent sync, but it is not your face.
Five questions sort them quickly:
- Does it start from your own photo, or only from its presenters?
- What does a 20 second clip cost at the resolution you will publish?
- How long does a render take?
- Does it watermark output on the plan you would buy?
- Can it speak in your own cloned voice?
Make one in four steps
- 1
Pick a photo that fills the frame
The face at least a third of the frame width, nothing across the mouth, even frontal light.
- 2
Write twenty seconds
One line of hook, two or three of substance, one of exit. Read it aloud before rendering.
- 3
Choose the voice
A preset for drafts and faceless videos, your clone when the video is about you.
- 4
Render at 480p for social
Save 720p for a close up that will be watched full screen.

Frequently asked questions
What should I look for in an AI talking head generator?
That it starts from your own photo, prices a 20 second clip clearly, renders in minutes rather than hours, does not watermark your output, and can speak in your cloned voice. Percify does all five, with one credit meter and no quality tiers.
How long should a talking head video be?
Short. Write for about twenty seconds and split longer scripts into two clips.
How much does an AI talking head video cost?
On Percify a talking video is 2 credits a second on the fast model at 480p, so 20 seconds is 40 credits, and 6 credits a second at 720p, 120 for 20 seconds. Using your own photo and saving your cloned voice cost nothing.
Can I use my own face and voice?
Yes. Your own photo is the face, so there is nothing to pay for it, and saving your cloned voice is free. The voice sample needs at least 5.6 seconds of clear speech; 15 to 30 seconds is better.
How long does it take to render?
A short clip at 480p is usually ready in a few minutes; longer clips and 720p take longer.
