LAPRAS Recap 2025

We developed a system that dynamically generates a video for each user based on their activity over the year, for a campaign by LAPRAS Inc. on LAPRAS, its portfolio service for engineers. The campaign, LAPRAS Recap 2025, looks back on each user's activity in 2025 through a video.

Dynamic Video Generation

The campaign targeted more than 10,000 users,

so producing a separate video for each of them with conventional video editing software was not realistic.

Instead, we used a tool called Remotion to generate the videos programmatically.

With this tool, you can "make videos with code" by writing code like the example below (simplified for illustration).

Remotion also lets you inspect the timeline in a GUI, just like conventional video editing tools.
