# Smart Edit Assistant

**Smart Edit Assistant** is an AI-powered web application that **automates video editing tasks** end-to-end. Users can upload video files, let the system **extract audio**, **transcribe** the speech (e.g., via Whisper), **analyze** content with GPT-like models, and **apply automated cuts and edits** using FFmpeg or MoviePy. The end result is a curated, shorter (or otherwise improved) video that can be downloaded, saving creators time on manual post-production.

## Features

- **Video Upload & Preview**: Upload `.mp4`, `.mov`, or `.mkv` files.
- **Audio Extraction**: Efficiently pulls the audio track for transcription.
- **AI Transcription**: Uses OpenAI Whisper (API or local) or other STT solutions.
- **LLM Content Analysis**: GPT-4 or open-source LLM suggests cuts and highlight segments.
- **Automated Editing**: Uses FFmpeg/MoviePy to cut and reassemble segments, optionally insert transitions.
- **Result Preview**: Plays the edited video in-browser before download.
- **(Optional) User Authentication**: Configurable free vs. premium tiers.

## Local Development & Setup

1. **Clone this repo**:
   ```bash
   git clone https://github.com/YourUsername/smart-edit-assistant.git
   cd smart-edit-assistant
Install Python dependencies:

bash
Copy code
pip install -r requirements.txt
If you plan to run open-source Whisper locally, ensure you install openai-whisper or the GitHub repo (git+https://github.com/openai/whisper.git).

If you’re using GPU, make sure your PyTorch install matches your CUDA version.

Run the app:

bash
Copy code
streamlit run app.py
Open http://localhost:8501 in your browser to interact with the UI.

Set Environment Variables (for GPT or Whisper API, if needed):

bash
Copy code
export OPENAI_API_KEY="sk-..."
or store in a local .env file and load with python-dotenv.

Deploying on Hugging Face Spaces
Create a Space:

Go to Hugging Face Spaces and create a new Space with the Streamlit SDK option.

Upload your files:

Either drag-and-drop via the web interface or push via Git:

bash
Copy code
git remote add origin https://huggingface.co/spaces/YourUsername/Smart-Edit-Assistant
git push origin main
Set your secrets:

In the Space’s Settings page, add OPENAI_API_KEY or any other API keys under “Secrets”.

If you want GPU, set hardware: "gpu" in the YAML frontmatter (as shown above) or in the Space settings.

Build and Launch:

The Space will automatically install your requirements.txt and run app.py.

Once deployed, your app is live at https://huggingface.co/spaces/YourUsername/Smart-Edit-Assistant.

Usage
Upload a Video: Click “Browse files” to select a .mp4, .mov, or .mkv file.

Extract & Transcribe: The app automatically pulls the audio, then uses Whisper or another STT method to get a transcript.

Generate Edits: An LLM (GPT-4 or local) analyzes the transcript and suggests where to cut or remove filler content.

Apply Edits: The app runs ffmpeg or MoviePy to create a new edited video file.

Preview & Download: You can watch the edited clip directly in the browser and then download the .mp4.

Configuration
Streamlit Config:

.streamlit/config.toml can set maxUploadSize (e.g. 10GB) or color theme.

Authentication:

If hf_oauth is true, users must log in with their Hugging Face account.

For custom username/password or free vs. premium tiers, see auth_utils.py or documentation in your code.

Roadmap
Interactive Timeline: Let users manually tweak the AI’s suggested cuts.

B-roll Insertion: Generate or fetch recommended B-roll and splice it in automatically.

Transition Effects: Provide crossfades, text overlays, or AI-generated intros/outros.

Multi-user Collaboration: Shared editing session or project saving in a database.

Troubleshooting
File Not Found or Zero Bytes: Make sure ffmpeg or MoviePy didn’t fail silently. Check logs for errors.

Whisper “load_model” Error: Ensure you installed openai-whisper or the GitHub repo, not the unrelated “whisper” PyPI package.

Large File Upload: If large uploads fail, confirm the maxUploadSize in .streamlit/config.toml is high enough, and verify huggingface secrets/config.

Performance: For best speed, request a GPU from Hugging Face Spaces or use a local GPU with the correct PyTorch/CUDA version.
