# Phoenix-4.5 Video Requirements
> Recording rules for training a Phoenix-4.5 face from video.
Use this path when you call [Create Face](/api-reference/faces/create-face) with **`model_name`: `phoenix-4.5`** and **`train_video_url`**. The video must be at a **publicly accessible URL**.
See [Choose a Model and Training Path](/sections/faces/which-training-path) if you are still deciding. Phoenix-4.5 does **not** support full-body, head-to-toe framing. For that, use [Phoenix-4 Video Requirements](/sections/faces/phoenix-4-video-requirements).
Video training automatically creates a voice from your recording audio and sets it as the face's `default_voice_id`. You can change it later with [Update Face](/api-reference/faces/update-face).
A zero-shot preview becomes usable in minutes, then tunes in the background. The preview carries a visible watermark; the later tuned version does not. Footage takes more effort than a photo, but the tuned face usually moves more naturally because tuning learns from your real movement.
## Camera & Framing
Record a seated or standing **chest-up** portrait for best results: mid-chest to just above the head, both shoulders in frame. Slightly wider (**waist-up**) or slightly closer both work. Do **not** record head to toe. For full body, use [Phoenix-4 Video Requirements](/sections/faces/phoenix-4-video-requirements).
* Place the camera at **eye level** so your face fills at least 25% of the frame
* **Use a stable camera** with your face centered and clearly visible
* **Sit at least 3 feet from the camera** in a natural, Zoom-style setup: head, shoulders, and upper chest clearly visible
* **Record in 1080p using a desktop app** - avoid browser recording and low resolution cameras
* Keep your neck visible with clear separation between your head and clothing
Glasses, jewelry, headphones, and hair in front of the shoulders are **allowed** as long as they do not cover the face. Shorter, crisp beards that leave the mouth and teeth visible work best - results may vary with dense or long beards.
Realistic, cartoon, anime, and Pixar-style humans are all fine. Animals, mascots, and other non-human figures are not.
## Supported Video Formats
Whether recording through the [PAL Maker](https://maker.tavus.io/dev/faces/create) or uploading a pre-recorded training video via the [API](/api-reference/faces/create-face), ensure your video meets the following requirements:
* **Minimum frame rate:** 25 FPS
* **Minimum resolution:** 1080p
* **Maximum file size:** 750 MB
* **Supported formats:** `.webm` and `.mp4` (H.264 video codec + AAC audio codec)
## Training Data Policy
All training data uploaded to Tavus must comply with our [Terms of Service](https://www.tavus.io/terms-of-service) and [Acceptable Use Policy](https://www.tavus.io/acceptable-use-policy). You are responsible for confirming you have permission to use any submitted content, including visual, audio, and identity-related assets.
## Recording Structure
Your video must be **one continuous shot**, containing **30 seconds of speaking** followed by **30 seconds of still footage**. You can use a script provided by Tavus or speak on any topic of your choice.
* **Speak naturally on any topic** - the content itself does not matter
* **Speak clearly and enunciate well** - keeping your teeth visible while talking
* **Keep head and body movement minimal**
* **Avoid hand gestures or sudden head turns**
Sample script (optional):
```txt expandable theme={null}
Once upon a time, people built a perfect park in the middle of a busy city. This park was big, bright, and full of playful paths. At sunrise, birds sang above the tall trees. Families carried baskets packed with bread, fruit, and juice.
Children skipped and shouted, chasing balls and flying paper kites. In the afternoon, people played games. Some tapped paddles and bounced plastic balls. Others kicked soccer balls back and forth, laughing loudly with every point scored.
```
* Keep your head **still** and **maintain eye contact with the camera**
* Keep lips **neutral and closed** throughout
* Do not lick lips or form unusual mouth shapes
* Avoid any head tilting or movement
Phoenix-4.5 becomes usable in minutes, then continues tuning in the background for a few hours. You can track progress by:
* Providing a `callback_url` when creating the Face via API
* Using the [Get Face](/api-reference/faces/get-face) API
* Checking the [PAL Maker](https://maker.tavus.io/dev)
### High-Quality Training Example
| Do | Don't |
| :-------------------------------------------------------- | :------------------------------------------------ |
| Keep your full face visible and in focus | Wear clothes that blend into the background |
| Sit still, facing the camera | Move around or change positions |
| Speak clearly with good enunciation (teeth fully visible) | Block your face or mouth with hands or microphone |
