Auto-generated beat videos

One beat. Four videos. JDTB renders a YouTube video, a YouTube Short, a TikTok, and an Instagram Reel from the same source files, each tuned to the format that platform actually accepts.

Why one video is not enough

A single MP4 cannot live on every platform. The shape that ranks on YouTube fails the upload check on TikTok. The version that survives Instagram's quiet quality cap is too small to read on a TV.

Producers who upload one video everywhere are slowly losing audience to producers who upload the right video everywhere.

Common questions

Renders on your machine, not on a queue

FFmpeg runs in your browser, so the audio never touches a server. Each variant is tuned for the platform's encoding rules so uploads pass first time.
