First–Last Frame Guide

The First–Last Frame (F–L) tab creates a smooth transition between two images—perfect for morphs, fades, and cinematic reveals.

1. Mode Selector

At the top, pick your generation mode:

  • T2V (Text → Video)

  • I2V (Image → Video)

  • SR (Subject Reference)

  • EXT (Extend Video)

  • F–L (First–Last Frame)

Tip: Select F–L to blend two images into one seamless clip.

2. Upload Your Frames

  1. First Frame: Click the upload box labeled “First Frame” and select your starting image.

  2. Last Frame: Click the upload box labeled “Last Frame” and select your ending image.

  3. Both thumbnails will appear—Boba.Video uses them as endpoints for the transition.

3. Settings Panel

Adjust these—or leave defaults for quick results:
