Minema: Legacy

Minema is a mod that allows you to record smooth videos in Minecraft even at extremely low frame rates by turning the Minecraft engine into an offline renderer.

This allows you to use very expensive rendering techniques which would normally be too slow for real-time rendering and capturing.

Technically, it can be compared with the startmovie command in Source engine or the fixed_time_step variable in CryEngine.

If you try to record, for instance, an explosion of 1,000,000 TNT blocks with tools like Fraps, Dxtory or Shadowplay, you would get nothing more than a slideshow. Even if your PC is fast enough for the targeted movie frame rate, it usually produces less smooth results than Minema. But keep in mind that this mod is designed for intermediate users that need to record cinematic or experimental Minecraft movies rather than for "normal" gameplay movies.

Known bugs

After movie capturing is finished, the integrated server may go into a "fast-forward" mode to re-sync with the real time.

Usage

To start and stop a recording session, simply press F4. The key can be configured in the key bindings menu.

If you're familiar with video encoding, it is highly recommended to use ffmpeg to compress videos on the fly.

Recommended ffmpeg parameters:

Lossy H.264:

-f rawvideo -pix_fmt rgb24 -s %WIDTH%x%HEIGHT%

-r %FPS% -i - -c:v libx264 -preset medium -qp 10 video.mp4

Lossless H.264 (RGB mode):

-f rawvideo -pix_fmt rgb24 -s %WIDTH%x%HEIGHT%

-r %FPS% -i - -c:v libx264rgb -preset medium -qp 0 video.mp4

Note: starting with Minema v3.2, all frames need to be flipped vertically using "-vf vflip"!
