# Project export: Vibe Video This document was generated by HackStack to give an AI agent context about a hackathon project. Sections are labeled with their provenance; content marked as truncated was cut to keep this document small. ## Project metadata - Hackathon: TreeHacks 2026 - Tagline: Let AI autonomously edit entire videos for you - Devpost: https://devpost.com/software/vibe-video-5ndrj4 - GitHub: https://github.com/Arihan10/Vibe-Video-Test - Team: 1 GitHub contributor(s) — Arihan Sharma (83 commits) ## Devpost submission (written by the team) ### Inspiration Video editing is stuck in the past. Tools like Premiere and Final Cut are powerful but painfully manual — you spend hours dragging clips around a timeline for what should be a creative process. Meanwhile, coding got "vibe coding" with Cursor. We asked: why can't video editing work the same way? Throw in your raw footage, get a real edit back, then iterate on it conversationally. ### What it does Vibe Video is an AI-powered video editor that turns raw clips into a fully edited video — then lets you refine it like you'd refine code in Cursor. Drop in your footage, and the AI assembles a coherent edit with cuts, ordering, and flow. From there, you can edit the transcript directly to change the video, give natural language instructions ("make the intro punchier," "cut everything after the second interview clip"), and watch your changes apply in real time. It's vibe editing. ### How we built it We built the frontend as a web app with a transcript-based editing interface that mirrors the Cursor-style inline editing experience. On the backend, we use AI to analyze and transcribe the uploaded clips, then intelligently sequence and cut them into a cohesive edit. The transcript serves as the single source of truth — edits to the text propagate back to the video timeline, so changing words literally changes the video. ### Challenges we ran into Video processing is slow. Getting the feedback loop tight enough that editing felt conversational rather than batch-job-and-wait was a constant battle. Syncing transcript edits back to precise video cuts without weird jumps or artifacts was also trickier than expected — off-by-a-frame errors add up fast. ### Accomplishments we're proud of The core loop actually feels good. You can go from a pile of raw clips to a watchable edit in minutes, and the transcript-driven editing is genuinely intuitive. The fact that it works end-to-end in a weekend is something we're proud of. ### What we learned Working with video programmatically is a whole different beast compared to text or images. We gained a much deeper appreciation for how hard real-time media manipulation is — and how much opportunity there is to make it better with AI. ### What's next Multi-track editing, AI-suggested b-roll and transitions, and support for longer-form content like podcasts and vlogs. We also want to add a collaborative mode where multiple people can vibe-edit the same project. The dream is to make video editing as fast as thought. ## README (from the GitHub repository) # Vibe-Video ## Backend (FastAPI) ### Setup - Python: **3.13 recommended** (your install log shows Python 3.14 fails building `pydantic-core`) - **FFmpeg** must be installed and available in PATH (for automatic audio extraction from video files) - Create and activate a virtualenv (recommended) - Install deps: - `pip install -r backend/requirements.txt` - Set environment variables: - `ASSEMBLYAI_API_KEY` - `GEMINI_API_KEY` You can use the template at `backend/env.example` and copy it to a local `.env` in `backend/` (or export vars in your shell). If you must stay on Python 3.14, one workaround is: - `export PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1` but the more reliable fix is using Python 3.13. #### Using pyenv (recommended) If you use `pyenv`, this repo includes `backend/.python-version` so `cd backend` will automatically select Python **3.13.1** (once pyenv is initialized in your shell). If `python3 -V` still shows 3.14 inside `backend/`, your shell likely isn't loading pyenv. Add the following to your dotfiles and restart the terminal: - `~/.zprofile`: - `export PYENV_ROOT="$HOME/.pyenv"` - `export PATH="$PYENV_ROOT/bin:$PATH"` - `eval "$(pyenv init --path)"` - `~/.zshrc`: - `eval "$(pyenv init - zsh)"` Then recreate the venv (from `backend/`): - `rm -rf .venv` - `python3 -m venv .venv` - `source .venv/bin/activate` - `python -m pip install -r requirements.txt` ### Run From the `backend/` directory: - `uvicorn app.main:app --reload` ### API - Health: `GET /health` - Subtitle pipeline: `POST /api/v1/subtitle` Example: - `curl -F "file=@/path/to/video.mp4" "http://localhost:8000/api/v1/subtitle"` Response includes: - Full transcript: `text` - Word timestamps: `words[]` - Re-segmented phrases: `phrases[]` ## Detected evidence (automated analysis) Indexed codebase: 94 recognized source files, 794 KB. - CSS (language) — detected in the code -

✅ 15 clips created from timeline.json - ✅ 15 segments with words extracted from reese_recordings.json - ✅ Total duration: 66.74 seconds - ✅ All timeline entries processed successfully ## Run the Application ```bash cd frontend npm run dev ``` Then open http://localhost:3000 ## What to Look For ### 1. Console Logs Open browser console (F12). You should see: ``` 📊 Data Loader Results: { totalClips: 15, totalSegments: 15, duration: 66.74, firstClip: {...}, firstSegment: {...} } ``` ### 2. Transcript Panel (Left Side) - Should display continuous text from all segments - Words should be clickable - Current word should highlight in blue during playback - Hover should show underline - Top should show "15 segments" ### 3. Timeline (Bottom) - Should show 15 clip blocks - Each block should have thumbnails (if generated) - Total timeline length: ~67 seconds - Clips should be positioned continuously (no gaps) ### 4. Video Preview (Center) - Should load video from `/videos/IMG_5243.MOV` - Video should play correctly - Scrubbing should update highlighted word ## Interactive Tests ### Test 1: Word Highlighting 1. Click play 2. Watch transcript - current word should highlight in blue 3. Timeline playhead should move in sync ### Test 2: Seek by Clicking Words 1. Click any word in transcript 2. Video should jump to that word's timestamp 3. Timeline playhead should update ### Test 3: Scrub Timeline 1. Drag timeline playhead 2. Transcript should highlight corresponding word 3. Video should show correct frame ## Data Structure Verification ### Check Zustand DevTools (if installed) 1. Install Redux DevTools Extension 2. Look for "EditorStore" in DevTools 3. Inspect state: - `segments` array should have 15 items - `clips` array should have 15 items - `duration` should be ~66.74 ### Manual Console Check ```javascript // In browser console: window.useEditorStore = require('@/stores/editorStore').useEditorStore; // Get current state const state = window.useEditorStore.getState(); console.log('Segments:', state.segments.length); console.log('Clips:', state.clips.length); console.log('Duration:', state.duration); console.log('First segment:', state.segments[0]); ``` ## Troubleshooting ### Video doesn't load - Verify `/videos/IMG_5243.MOV` exists in `frontend/public/videos/` - Check browser console for 404 errors - Video path in data-loader.ts line 103: `src: '/videos/IMG_5243.MOV'` ### No words showing in transcript - Check console for "Data Loader Results" log - Verify `segments` array is not empty - Check for errors in data-loader.ts ### Timeline is empty - Check console for Timeline render logs - Verify `clips` array has data - Check Timeline.tsx is using Zustand store ### Words don't highlight during playback - Verify PlayerContext is providing currentTime - Check SegmentDisplay.tsx activeTimelineWord calculat [truncated — 874 more characters] ``` ### FIXED_TIMELINE_JSON.md ```markdown # ✅ FIXED: All Components Now Use timeline.json ## What Was Changed ### 1. EditorContext.tsx - NOW USES TIMELINE.JSON ✅ **Before:** ```typescript import sampleEditData from '@/lib/sampleEdit.json'; import mockTranscript2 from '@/lib/mockTranscript2.json'; const [editData, setEditData] = useState(() => migrateLegacyData(sampleEditData as unknown as EditData) ); ``` **After:** ```typescript import { useEditorStore } from '@/stores/editorStore'; // Get data from Zustand store (which loads from timeline.json) const zustandClips = useEditorStore(state => state.clips); const zustandSegments = useEditorStore(state => state.segments); const zustandDuration = useEditorStore(state => state.duration); // Convert to EditorContext format const [editData, setEditData] = useState(() => convertZustandToEditData(zustandClips, zustandSegments, zustandDuration) ); ``` **Result:** EditorContext is now a wrapper around Zustand store, which loads from `timeline.json` + `reese_recordings.json` ### 2. VideoPlayer.tsx - NOW USES TIMELINE.JSON ✅ **Before:** ```typescript import editData from "@/lib/sampleEdit.json"; const [duration] = useState(editData.duration); ``` **After:** ```typescript import { useEditorStore } from "@/stores/editorStore"; const clips = useEditorStore(state => state.clips); const duration = useEditorStore(state => state.duration); ``` ### 3. save-edit API - NOW SAVES TO project.json ✅ **Before:** ```typescript const filePath = path.join(process.cwd(), "lib", "sampleEdit.json"); ``` **After:** ```typescript const filePath = path.join(process.cwd(), "lib", "project.json"); // Saves format: { clips, segments, duration } ``` ## Data Flow (COMPLETE) ``` ┌─────────────────────────────────────────────┐ │ Source Files (User's Timeline Data) │ ├─────────────────────────────────────────────┤ │ • reese_recordings.json │ │ • timeline.json │ └─────────────────────────────────────────────┘ ↓ ┌─────────────────────────────────────────────┐ │ Data Loader (data-loader.ts) │ ├─────────────────────────────────────────────┤ │ • Processes timeline array │ │ • Extracts words from reese_recordings │ │ • Converts ms → seconds │ │ • Creates clips[] and segments[] │ └─────────────────────────────────────────────┘ ↓ ┌─────────────────────────────────────────────┐ │ Zustand Store (editorStore.ts) │ ├─────────────────────────────────────────────┤ │ State: │ │ • clips: TimelineClip[] (15 items) │ │ • segments: Segment[] (15 items) │ │ • duration: 66.74s │ └─────────────────────────────────────────────┘ ↓ ┌───────┴────────┐ ↓ ↓ ┌──────────┐ ┌──────────────┐ │ Direct │ │ EditorContext│ │ Zustand │ │ (Wrapper) │ │ Users │ │ │ └──── [truncated — 2139 more characters] ``` ### backend/pyproject.toml ``` [project] name = "backend" version = "0.1.0" description = "Add your description here" readme = "README.md" requires-python = ">=3.13.1" dependencies = [] ``` ### backend/requirements.txt ``` annotated-types==0.7.0 anyio==4.12.1 certifi==2026.1.4 charset-normalizer==3.4.4 click==8.3.1 fastapi==0.115.8 google-auth==2.47.0 google-genai==0.8.0 h11==0.16.0 httpcore==1.0.9 httptools==0.7.1 httpx==0.28.1 idna==3.11 pyasn1==0.6.2 pyasn1_modules==0.4.2 pydantic==2.10.6 pydantic-settings==2.7.1 pydantic_core==2.27.2 python-dotenv==1.2.1 python-multipart==0.0.9 PyYAML==6.0.3 requests==2.32.3 rsa==4.9.1 starlette==0.45.3 typing_extensions==4.15.0 urllib3==2.6.3 uvicorn==0.34.0 uvloop==0.22.1 watchfiles==1.1.1 websockets==14.2 ``` ### frontend/package.json ``` { "name": "frontend", "version": "0.1.0", "private": true, "scripts": { "dev": "next dev", "build": "next build", "start": "next start", "lint": "eslint" }, "dependencies": { "@ffmpeg/ffmpeg": "^0.12.15", "@ffmpeg/util": "^0.12.2", "@lexical/react": "^0.39.0", "@twick/browser-render": "^0.15.7", "@twick/studio": "^0.15.7", "@types/crypto-js": "^4.2.2", "assemblyai": "^4.22.1", "crypto-js": "^4.2.0", "form-data": "^4.0.5", "lexical": "^0.39.0", "next": "16.1.4", "react": "19.2.3", "react-dom": "19.2.3", "zustand": "^5.0.10" }, "devDependencies": { "@tailwindcss/postcss": "^4", "@types/node": "^20", "@types/react": "^19", "@types/react-dom": "^19", "eslint": "^9", "eslint-config-next": "16.1.4", "tailwindcss": "^4", "typescript": "^5" } } ``` ### backend/main.py ```python def main(): print("Hello from backend!") if __name__ == "__main__": main() ``` ### frontend/app/page.tsx ```typescript import Studio from '../components/Studio';
