Creatoria

The creator toolkit for Flashback Flashback records the world beautifully. Creatoria records everything else: the inventories you open, the chat you type, your voice, the music in your ears. And when you'd rather go live than record, it can stream straight from the pause menu.

No extra software and no setup beyond the stream key you paste in once. Install it next to Flashback and play.

🎒 Every screen, replayed exactly Opening a chest normally leaves no trace in a replay. The camera just shows the world while you shuffle items off-screen. With Creatoria, spectate yourself in first person and the real vanilla GUI is drawn back over your view, frame by frame.

Inventories and containers: your inventory, chests, barrels, shulker boxes, furnaces, crafting tables, brewing stands, anvils, enchanting tables, villager trades, hoppers, beacons and more. Your cursor: mouse movement is replayed smoothly, so slot highlights, item tooltips and the item on your cursor appear exactly where they were. Live progress: furnace arrows, brewing bubbles and anvil costs move just as they did while you played. Chat: the full chat history, the message you were typing (caret and selection included), how far you'd scrolled back, and hover tooltips on messages. Scrub, pause or jump anywhere on the timeline and the right screen is always shown. It all appears in your exported videos too, and it respects Flashback's No GUI and Show Chat settings.

🎙️ Your voice and your PC audio, in sync Creatoria records your microphone and your computer's audio alongside every replay. Computer audio means Discord, music, videos and anything else, except Minecraft itself. Flashback already replays the game's sounds, so nothing is heard twice.

When you open the replay, they appear in the Flashback editor as Microphone and Computer Audio tracks with waveforms:

They stay in sync while you scrub, pause or seek. Exactly one tick of audio is recorded per replay tick, so lag and pauses never knock them out of sync. Mute either track with a click. They're mixed into your exported videos automatically. If your headphones connect or disconnect mid-recording, capture picks itself back up on the new device. 🔴 Go live from the pause menu Stream straight to Twitch, YouTube or any RTMP server:

Open Pause → Stream & Audio..., click Twitch or YT, and paste your stream key. Hit ● Go Live. The stream shows exactly what's on your screen, HUD and menus included, along with everything your PC is playing. Pick 480p to 1440p at 30 or 60 fps and choose your bitrate. Creatoria uses your NVIDIA or Intel GPU encoder when you have one, and a multithreaded software encoder otherwise. You can also bind a key to start and stop the stream.

⚡ Built to stay out of your way Idle when nothing's open. With no inventory or chat on screen, each tick costs a single check and nothing is written. Only records changes. Open screens save just the slots that changed, plus the cursor: about 1–2 KB per second at most. Compact audio. Opus, encoded on a background thread, at about 0.5 MB per minute for the mic and 1 MB per minute for PC audio. Nothing extra while you watch. Playback draws one vanilla screen, and only while you're spectating yourself in first person. Hands-off. It never alters your replay's entities and never sends anything to a server. Live streaming is the one feature with a real cost, as with any streaming software, and only while you're live. Frames are captured and scaled on the GPU without stalling the game, and encoding runs on background threads. A GPU encoder keeps the impact small. Software encoding handles 720p in about 11 ms per frame on a modern laptop CPU.

Getting started Install Creatoria with Flashback 0.39.x and Fabric API. Record with Flashback as usual. A toast confirms which audio sources are recording, and you can switch them in Pause → Stream & Audio.... Open the replay and spectate yourself in first person. Requirements Minecraft 1.21.11 with Fabric Flashback 0.39.x Fabric API Client-side only. Works in singleplayer and on any server. Audio recording and stream audio need Windows 10 (version 2004) or newer. Good to know Only your own screens can be recorded. Servers never send other players' inventories to your client. The creative inventory is shown with the survival layout, and the recipe-book panel isn't drawn. Commands typed in chat are replayed without syntax colouring or the suggestion popup. Modded containers work if they use a standard menu. Ones that need extra data to open are skipped. AMD GPUs stream with the software encoder, because Flashback's bundled FFmpeg has no AMD encoder. Long recordings (an hour or more) with audio use a lot of memory in the Flashback editor, because Flashback loads audio tracks fully into RAM. Your stream key is stored in plain text in config/creatoria.json. Keep that file to yourself. Creatoria is an unofficial addon.
