🧰 FFmpeg Batch Compressor

A simple shell script for Linux that batch-compresses video files using FFmpeg (H.265 / HEVC).
It automatically skips videos that are already compressed or re-encodes broken/incomplete ones.

---

✨ Features

• Compresses MKV, MP4, AVI, MOV, FLV, WEBM, WMV, TS and more.
• Keeps subtitles, audio, and metadata intact.
• Automatically skips completed files.
• Re-encodes files if they're broken, too small, or have mismatched duration.
• Creates a compressed/ folder automatically.
• Tested and confirmed working on Arch-based distros (e.g. CachyOS, Arch Linux, Manjaro).

🧩 Requirements

• 🐧 Linux (preferably Arch-based systems)

• 🧠 Shell: Bash (works in Konsole, Fish, or any standard terminal)

• ⚙️ Packages:

  sudo pacman -S ffmpeg
  

• (Optional) chmod permission to make it executable.

🚀 Installation & Usage

1. Clone or copy the repository

git clone https://your-repo-link.git
cd ffmpeg-batch-compressor

2. Make the script executable

chmod +x compress.sh

3. Run it in a folder containing your video files

./compress.sh

By default, it creates a compressed/ folder inside the current directory
and saves all processed videos there.

🧠 Optional: Run on another folder

You can also run the script on a specific path:

/path/to/compress.sh /path/to/videos

(requires a small edit in the script — or simply cd into that folder first)

If your folder looks like this:

/home/user/Anime/

  ├── Episode02.mp4
  └── compress.sh

After running ./compress.sh, you'll get:

/home/user/Anime/compressed/
