Yueyue Flashback Extension

Yueyue Flashback Extension

An independent client-side add-on by Yisibite for Minecraft 26.3 / Fabric / Java 25, currently supporting Flashback 0.43.6. New recordings gain an optional transparent GUI track containing the recorder's health, armor, hunger, experience, hotbar, chat and hints, inventory and container screens, visible items/counts/tooltips, and cursor. Mod screens using the same GUI rendering pipeline can also be captured.

Recording and export

In Flashback's export window, choose whether to include the recorded interface, follow the recorder's first-person camera, preview the interface in the editor, and record the interface in new replays. Camera follow and interface export are independent. The original Hide GUI option takes priority, depth exports do not include the overlay, and each export job keeps its own settings. Disable interface export for a clean first-person world view.

Only new recordings contain this data; older replays cannot recover screens that were never recorded. Self-contained snapshots support forward/backward seeking and pause/resume. The track is optional, so base Flashback can skip it after this add-on is removed. It records rendered screens without replaying clicks, crafting, trading or world actions.

GUI capture is limited to 20 samples per second, with asynchronous GPU readback/PNG encoding, bounded queues and identical-pixel deduplication. Busy processing keeps the newest interface and may skip intermediate samples. World export still uses Flashback's export frame rate. This is a game GUI track, not an operating-system screen recorder; independent external render layers and every third-party shader combination are not guaranteed to match pixel for pixel.

Installation

• Minecraft 26.3, Fabric Loader 0.19.5+, Java 25. Client only.
• Install official Flashback 0.43.6 and its dependencies separately to use the extension.
• Without Flashback or with an unsupported version, extension features stay hidden and the game can still start.
