First-Last Frame
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
First Frame: Click the upload box labeled “First Frame” and select your starting image.
Last Frame: Click the upload box labeled “Last Frame” and select your ending image.
Both thumbnails will appear—Boba.Video uses them as endpoints for the transition.
