Lumiera

Players open the timeline with G, fly the camera to a position and press a key to drop a keyframe. The scrub timeline previews the shot, and each segment can be given its own easing, from plain ease in and out to quad, cubic and sine curves, or a straight line or Catmull-Rom path between keyframes. Field of view, roll and aim lock can be animated per keyframe. Fades, colour-ramp veils, bars across the frame, captions and messages can be added to a shot.

Timed events hang off the path: sound and particle cues, screen shake, and actor staging for entities, players, items, blocks, armor stands and particles. Each actor can get its own pose keyframes and timed actions such as swinging, jumping or attacking, and events can fire on breaking a block or a dying entity. Cutscenes and camera paths are stored per world in data files that can be renamed, duplicated or shipped as JSON under the data folder, and times can be given in ticks or seconds. Command blocks on a server reach the same functions through the lumiera command.

Lumiera requires Fabric API. It runs on Fabric, Forge and NeoForge, and the same build works on every loader it is installed on. Files target 1.20.1, 1.21.1, 26.1, 26.1.1 and 26.1.2, with the latest builds for 26.1.2 on Fabric and NeoForge and 1.20.1 on Forge, all in the alpha channel. The mod works on either side, and neither needs it, and it is published under a custom license that is not open source.
