Note: The app expects ffmpeg to be available on the system (also installs via apt.txt on Spaces).

⚙️ Prerequisites

• Python 3.10+
• FFmpeg (includes ffmpeg and ffprobe)
• git & a terminal

Install FFmpeg locally:

Ubuntu/Debian

sudo apt update && sudo apt install -y ffmpeg

macOS (Homebrew)

brew install ffmpeg

Windows (winget)

winget install Gyan.FFmpeg

---

🔧 Installation

1. Clone this repository:

git clone https://github.com/salmanalfarisi11/video-converter.git
cd video-converter

1. Create and activate a virtual environment:

python -m venv .venv
# Linux/macOS
source .venv/bin/activate
# Windows
.venv\Scripts\activate

1. Install Python dependencies:

pip install -r requirements.txt

---

🚀 Running Locally

Start the app:

python videoconverter.py

• Default URL: http://127.0.0.1:7860
• Want a temporary public link? Set share=True in demo.launch(...).

---

🎯 Usage

1. Upload a video or audio file.
2. Choose a target format (to video / to audio).
3. (Optional) Set CRF and Ultra fast preset.
4. Click Convert. A modal “Converting…” appears and the UI is locked.
5. When done, click the Download result button to save your file.

⚙️ Settings (CRF & Preset)

• CRF H.264 (lower = better quality)

  • Applies to H.264 outputs (e.g., mp4, mov).
  • Typical range: 18–28.
  • Lower CRF → higher quality & bigger file, conversion a bit slower.
  • Higher CRF → smaller file, conversion faster.

• Ultra fast preset (ultrafast)

  • Uses -preset ultrafast for libx264 to speed up CPU encoding at the cost of larger files.
  • Uncheck it if you prefer better compression (smaller size) with slower conversion.

---

☁️ Deploy to Hugging Face

1. Create a New Space → Gradio → (Public or Private).

2. Upload these files:

   • videoconverter.py

   • requirements.txt (e.g., gradio==5.32.1)

   • apt.txt with:

     ffmpeg
     

   • README.md, LICENSE, .gitignore (optional but recommended)

3. In README.md, you can add HF metadata front-matter (optional):

---
title: Free Video Converter
emoji: 🎬
colorFrom: indigo
colorTo: purple
sdk: gradio
sdk_version: 5.32.1
app_file: videoconverter.py
license: other   # proprietary
pinned: false
---

The Space will build and run automatically.

---

🛠️ Troubleshooting

• “FFmpeg not found” Ensure ffmpeg is installed and on your PATH (ffmpeg -version). On Spaces, keep ffmpeg inside apt.txt.

• Conversion is slow

  • Enable Ultra fast preset.
  • Use a higher CRF for H.264.
  • Prefer mp4/mp3 which are typically faster on CPU.

• Out of storage (Spaces with small disks)

  • Delete large outputs frequently.
  • Reduce file sizes using higher CRF or lower bitrates.
