Subject Reference Guide

The Subject Reference (SR) tab lets you animate a specific person or object using your own reference images. Upload your subject once, then direct it in video.

1. Mode Selector

At the top, pick your generation mode:

  • T2V (Text → Video)

  • I2V (Image → Video)

  • SR (Subject Reference)

  • EXT (Extend Clip)

  • F-L (First Frame → Last Frame)

Tip: Select SR to bring your reference images to life.

2. Add Reference Image

  1. Click Select or Upload Image or drag-and-drop into the box.

  2. Upload 1–5 images of your subject (different angles help!).

  3. Your images appear as thumbnails—Boba.Video uses them to learn your subject’s appearance.

3. Settings Panel

Leave defaults or tweak as needed:

Hover for a quick preview or click to view full-screen.

6. Post-Processing Controls
