I built a two-photo video generator for the Alors on danse keyboard meme

Description and use

Users upload two photos, assign roles, and receive a 16‑second MP4 with original audio via a simple web interface.

Problem

Users need a simple way to create a 16‑second video of a keyboard‑playing scene with two chosen subjects without complex prompts or editing.

Outcome

The generator produces a 16‑second, 720p, 16:9 landscape MP4 with the original soundtrack, using two user‑supplied photos mapped to fixed roles.

Workflow

• Sign in with Google
• Select a video pack
• Upload a photo for the keyboard player (left slot)
• Upload a photo for the partner (right slot)
• Click generate
• Wait for processing
• Download the MP4 from My videos

Evidence

The first photo becomes the keyboard player. The second becomes the partner reacting alongside them.

Source

The standard output is a 16-second, 720p, 16:9 landscape MP4.

The generation pipeline has two stages. Seedance 2.5 through KIE generates the video with audio generation turned off. A separate FAL step merges the fixed soundtrack into the result.
