Perfect Flow
Perfect Flow records Minecraft frames offline, frame by frame, so a finished video can be captured without dropped frames.
What it does
Perfect Flow is a client-side mod for Fabric and Forge that renders the game offline, one frame at a time, and saves the result as video. Frame timing is controlled by the mod rather than by the real clock, which keeps captured footage even when the machine runs slowly. Output can be an MP4 encoded through an external FFmpeg executable, or a TGA image sequence. An optional alpha channel can be written with the frames for compositing.
Required dependencies are Cloth Config API and Fabric API. Iris Shaders, Mod Menu and Oculus are optional: Iris and Oculus let shader packs appear in captures, and Mod Menu gives access to the settings screen. Only the client needs the mod, so a server does not have to run it. Perfect Flow is open source under the MIT License and has public source code and an issue tracker. Files target 1.18.2 – 1.20.6 across six release versions, with the latest Forge file for 1.20.4 dated 2026-07-18.
Key features
Offline frame-perfect capture
Frames are rendered in sequence without real-time pacing, so every captured frame is complete and in order.
MP4 export
Video is encoded to MP4 by an external FFmpeg executable that the player points the mod to.
TGA sequence export
Each frame can be saved as a numbered TGA image, which suits editors that import image sequences.
Alpha and motion blur
An optional alpha channel can be written with the frames, and motion blur is supported in the capture.
Iris shader capture
Shader packs running through Iris can be included in the captured frames.

Use cases
Cinematic recordings
Creators who need smooth footage of a scene can render it offline instead of recording live gameplay.
Compositing
Exports with an alpha channel and image sequences can be layered in external editing software.
Who it’s for: Video creators and players who record gameplay for editing, especially when smooth frame timing matters more than real-time play.
How it compares
Motion Blur Plus is client-side only, published for Fabric from 1.21.10 onward, and is not open source under the MIT License. Perfect Flow covers 1.18.2 – 1.20.6 for both Fabric and Forge. SC StructureCraft is a Forge mod for 1.20.1 under All rights reserved, so it does not offer Fabric builds like Perfect Flow does.
