Spaghetti Lab - Replay Analyzer

## Analyze and Annotate Your Fighting Game Replays Spaghetti Lab is the dedicated replay analysis tool built by Spaghetti Showdown. Available as both a desktop application and a web-based analyzer, Spaghetti Lab lets you open replay files, add detailed notes and drawings, and share your analysis with coaches, training partners, or the broader community. ### Desktop App vs Web Analyzer Spaghetti Lab comes in two versions: **Desktop Application:** - Available for Windows and macOS - Runs natively for the best performance - Can open local video files directly from your hard drive - Supports larger file sizes without browser memory limitations - Includes advanced frame-by-frame analysis tools **Web Analyzer:** - Runs entirely in your browser — no installation required - Access it from the Tools section on Spaghetti Showdown - Supports YouTube and Twitch video embedding - Perfect for quick reviews and sharing via URL - Integrated directly with the coaching and replay review systems Both versions use the same **.spag** and **.spagz** file formats, so annotations created in one can be opened in the other seamlessly. ### Opening .spag and .spagz Files Spaghetti Lab uses two proprietary file formats: - **.spag** — A replay data file that stores match information, inputs, and metadata. These files are typically exported from supported games or recorded through the platform. - **.spagz** — An annotation file that layers notes, drawings, and timestamps on top of a video or .spag file. This is the format produced when you annotate a replay. To open a file, click **Open File** in Spaghetti Lab and select your .spag or .spagz file. The desktop app also supports drag-and-drop — simply drag the file into the application window. ### Adding Notes The notes system lets you attach detailed commentary to specific moments in the replay: - **Click on the timeline** at any point to create a new note - **Write your analysis** — describe what happened, what could have been done differently, and what to practice - **Tag your notes** with categories like Punish Opportunity, Spacing Error, Good Decision to organize your analysis - **Link notes together** to show cause-and-effect sequences Notes are displayed alongside the video and can be navigated with keyboard shortcuts for efficient review. ### Drawing on Frames Pause at any frame and use the drawing tools to illustrate your points: - **Freehand drawing** for quick sketches and markups - **Arrow tool** for indicating movement direction, attack trajectories, or spacing adjustments - **Shape tools** for highlighting areas of the screen — hitboxes, safe zones, or positioning references - **Text overlay** for labeling elements directly on the frame - **Color picker** with preset colors for consistent annotation styles Drawings are saved with their timestamps, so they appear and disappear at the correct moments during playback. ### Sharing Your Analysis Once your analysis is complete, you can share it in several ways: - **Export as .spagz** to share the full interactive annotation - **Generate a shareable link** (web version) that anyone can view in their browser - **Attach to a coaching review** if you are analyzing a student replay - **Download as PDF** for a static summary of your notes and key frames Spaghetti Lab turns casual replay watching into a structured, productive study session. ### Watch Party — Rewatch Together Watch Party lets you synchronize video playback with other people in real time. It is perfect for rewatching replays together while adding notes — hop on a Discord call with your friends or coach, start a Watch Party, and everyone sees the same thing at the same time. **How it works:** 1. **Open any video** in the Spaghetti Lab analyzer (a .spag/.spagz file, a YouTube link, a Twitch clip, or an uploaded video file) 2. **Click the purple Watch Party button** in the top-right header bar 3. A **party status bar** appears with a **Copy Link** button — share this link with anyone you want to watch with 4. **Viewers open the link** and the video loads automatically, synced to your playhead **Host controls:** - You (the host) control playback for everyone — play, pause, seek, and all viewers follow along - A **viewer count badge** shows how many people are watching - Click **End Party** to close the session for everyone **Viewer experience:** - The video plays in sync with the host — if they pause, you pause; if they skip ahead, you skip ahead - A **green sync indicator** shows you are in sync; it briefly turns yellow while catching up after a seek - You can still browse notes and drawings while watching - You are in read-only mode — the host controls playback **Tips:** - Use Discord, Telegram, or any voice chat alongside Watch Party for discussion — Watch Party handles video sync only - Watch Party works with all video sources: uploaded files, YouTube embeds, and Twitch clips - Party sessions last up to **4 hours** and automatically expire after that - You need to be **logged in** to both host and join a Watch Party
