Use custom avatar images to create personalized digital personas. Follow these technical specifications and guidelines to ensure optimal results for custom avatars generated from text or by uploading an image.

​
Technical specifications

​
File format

  • Supported formats: .png or .jpg
  • Resolution: Minimum of 720x480 pixels (higher resolutions preferred)
  • Aspect ratio: Widescreen format, either 3:2 or 16:9
Example: hunter_table.png

​
Subject pose and expression

​
Facial focus

The subject’s face must be in sharp focus with the following characteristics:
  • Gaze: Looking directly at the camera
  • Camera angle: Slightly low angle so the subject appears to be looking down slightly, similar to their appearance on a video call
  • Facial expression: Neutral expression required
    • No extreme expressions
    • Face should appear relaxed
    • Mouth should be closed but not held tightly
  • Pose reference: Replicate the provided reference pose as closely as possible

​
Framing and composition

​
Centering

  • Horizontal: Position the subject in the center of the frame
  • Vertical: Position the subject’s mouth-line at approximately 50% of the frame height

​
Additional framing guidelines

  • Headroom: Adequate vertical space above the subject’s head, equivalent to roughly 25% of the total image height
  • View: The subject’s shoulders and chest must be clearly visible in the shot
  • Body orientation: The subject should be facing the camera directly

​
Environment and appearance

​
Clothing

Avoid wearing clothing with large text or distracting logos.

​
Background

Simple, uncluttered backgrounds are preferred.

​
Camera distance

The ideal distance between the camera and the subject is approximately 2 meters, although this may vary depending on the camera lens used.

​
Improving jitter and lip-sync

If you experience issues with jittery shoulders or poor lip sync and expressivity, try this technique:
1

Create initial avatar

Go to https://lab.anam.ai/avatars and click to Create Avatar.
2

Generate first version

Take or upload a picture and start creating a 1-shot avatar with your image.
3

Capture neutral frame

During step 3, the system will show you the motion of the new persona you’ve created. Pause the video on a frame with open eyes and a neutral expression.
4

Save the frame

Right-click on the video and select “Save video frame as…”
5

Use the saved frame

Use that image to create your 1-shot from by starting the creation flow again.
6

Optional: Upscale resolution

If the resolution is low, use a tool like magnific to upscale it.
