VideosToWebMConverter

This Python utility scans a directory for supported video files and converts them to WebM format. Converted assets are stored in a WebM_Videos subfolder and encoded with VP9 + Opus via ffmpeg.

Features

• Batch converts every supported video in a directory.
• Handles .mp4, .avi, .mov, .mkv, .flv, and .wmv files.
• Requests the target video bitrate from the user (defaults to 1M if omitted).
• Prints original and converted file sizes when each conversion completes.

Requirements

• Python 3.7+ (only standard library modules are used).
• An ffmpeg installation accessible on your system PATH.

# verify ffmpeg availability
ffmpeg -version

Installation

1. Clone or download the repository:

   git clone <repo-url>
   cd VideoToWebMConverter

2. (Optional) create and activate a virtual environment.
3. Make sure ffmpeg is installed.

Usage

Run the script from a terminal:

python VideosToWebMConverter.py

The script prompts you for:

1. The directory containing the videos you want to convert.
2. A target video bitrate (press Enter to keep the default 1M).

For each video, progress and file-size information appears in the console. Converted files are saved under WebM_Videos inside the input directory.

Importing the module

You can also call convert_videos_to_webm from another Python module:

from VideosToWebMConverter import convert_videos_to_webm

convert_videos_to_webm(
    directory_path="/path/to/videos",
    video_bitrate="2M",  # optional override
)

How It Works

1. Creates (or reuses) a WebM_Videos folder inside the source directory.
2. Checks file extensions and skips unsupported items with a short message.
3. Executes ffmpeg with the libvpx-vp9 video codec and libopus audio codec.
4. Reports original and converted sizes in MB once each conversion finishes.

Troubleshooting

• Error: FFmpeg bulunamadı...: ffmpeg is missing from the PATH. Install it or add the executable path to your environment variables.
• CalledProcessError: ffmpeg encountered an error. Inspect the console output; you may have an unsupported codec, a corrupted file, or a permissions issue.
• Conversions for very large files taking too long? Try a lower bitrate such as 800K.
