From 33cca5f552d784ff79db07b2570737d487f9fba2 Mon Sep 17 00:00:00 2001 From: Your Name Date: Tue, 3 Mar 2026 06:31:04 -0500 Subject: [PATCH] Initial CutScript release - Open-source AI-powered text-based video editor CutScript is a local-first, Descript-like video editor where you edit video by editing text. Delete a word from the transcript and it's cut from the video. Features: - Word-level transcription with WhisperX - Text-based video editing with undo/redo - AI filler word removal (Ollama/OpenAI/Claude) - AI clip creation for shorts - Waveform timeline with virtualized transcript - FFmpeg stream-copy (fast) and re-encode (4K) export - Caption burn-in and sidecar SRT generation - Studio Sound audio enhancement (DeepFilterNet) - Keyboard shortcuts (J/K/L, Space, Delete, Ctrl+Z/S/E) - Encrypted API key storage - Project save/load (.aive files) Architecture: - Electron + React + Tailwind (frontend) - FastAPI + Python (backend) - WhisperX for transcription - FFmpeg for video processing - Multi-provider AI support Performance optimizations: - RAF-throttled time updates - Zustand selectors for granular subscriptions - Dual-canvas waveform rendering - Virtualized transcript with react-virtuoso Built on top of DataAnts-AI/VideoTranscriber, completely rewritten as a desktop application.

Troubleshooting Common Issues - -#### Tokenizers Installation Issues - -If you encounter issues with `tokenizers` installation: - -1. Make sure you have Visual C++ Build Tools installed (Windows) -2. Try installing Rust: [rustup.rs](https://rustup.rs/) -3. Install tokenizers separately: - ```bash - pip install tokenizers --no-binary tokenizers - ``` - -#### PyAnnote.Audio Access - -To use speaker diarization, you need a HuggingFace token with access to the pyannote models: - -1. Create an account on [HuggingFace](https://huggingface.co/) -2. Generate an access token at [huggingface.co/settings/tokens](https://huggingface.co/settings/tokens) -3. Request access to [pyannote/speaker-diarization-3.0](https://huggingface.co/pyannote/speaker-diarization-3.0) -4. Set the token in the application when prompted or as an environment variable: - ```bash - # Windows - set HF_TOKEN=your_token_here - # macOS/Linux - export HF_TOKEN=your_token_here - ``` - -#### Memory Issues with Large Files - -If you encounter memory issues with large files: - -1. Use a smaller Whisper model (e.g., "base" instead of "large") -2. Reduce the GPU memory fraction in the application settings -3. Increase your system's swap space/virtual memory - -## Running the Application - -After installation, run the application with: - -```bash -streamlit run app.py -``` - -## Optional: Ollama Setup for Local Summarization - -To use Ollama for local summarization: - -1. Install Ollama from [ollama.ai](https://ollama.ai/) -2. Pull a model: - ```bash - ollama pull llama3 - ``` -3. Uncomment the Ollama line in requirements.txt and install: - ```bash - pip install ollama - ``` - -## Verifying Installation - -To verify that all components are working correctly: - -1. Run the application -2. Check that GPU acceleration is available (if applicable) -3. Test a small video file with basic transcription -4. Gradually enable advanced features like diarization and translation - -If you encounter any issues, check the application logs for specific error messages. \ No newline at end of file diff --git a/LICENSE b/LICENSE index 83db24d..0989410 100644 --- a/LICENSE +++ b/LICENSE @@ -1,6 +1,6 @@ MIT License -Copyright (c) 2025 DataAnts-AI +Copyright (c) 2026 DataAnts AI Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal diff --git a/QUICK-FIX.md b/QUICK-FIX.md deleted file mode 100644 index e085af5..0000000 --- a/QUICK-FIX.md +++ /dev/null @@ -1,63 +0,0 @@ -# 🚨 Quick Fix for PyTorch Compatibility Error - -If you're seeing the `torch.compiler.disable` error, here's how to fix it: - -## Immediate Fix - -```bash -# Stop the current container -docker-compose down - -# Remove the old image to force rebuild with fixed versions -docker rmi $(docker images | grep videotranscriber | awk '{print $3}') - -# Rebuild with fixed dependencies -docker-compose up -d --build -``` - -## Better Solution: Use Prebuilt Images - -⚠️ **Note**: GitHub Actions had a naming issue that's now fixed.
