video_utils

A collection of utilities for video processing, including resizing videos with bitrate and audio quality control, and format conversion using FFmpeg.

Features

• Change video resolution with customizable width and height
• Control video bitrate and audio quality (codec, bitrate, channels, sample rate)
• Progress bar with ETA during processing
• Automatic bitrate estimation if not specified
• Format conversion (e.g., MKV to MP4)
• Requires FFmpeg installed and available in your system PATH

Requirements

• Python 3.x
• OpenCV (cv2)
• FFmpeg (must be installed and in your system PATH)

Installation

# Clone the repository
git clone https://github.com/lpferreira33/video_utils.git

# Create and activate .venv
python -m venv .venv
.venv\Scripts\activate.ps1

pip install opencv-python

Usage

Resize Video

python video_resize.py input_video.mp4 output_video.mp4 --width 1280 --height 720

With audio quality control:

python video_resize.py input_video.mp4 output_video.mp4 --width 1280 --height 720 --audio-codec aac --audio-bitrate 96

All options:

• --width: Target width (pixels, required)
• --height: Target height (pixels, required)
• --bitrate: Target video bitrate in kbps (optional)
• --audio-codec: Audio codec (e.g., aac, mp3, opus)
• --audio-bitrate: Audio bitrate in kbps (e.g., 128, 192, 256)
• --audio-channels: Number of audio channels (e.g., 1 for mono, 2 for stereo)
• --audio-sample-rate: Audio sample rate in Hz (e.g., 44100, 48000)

Convert MKV to MP4

See mkv2mp4.py for MKV to MP4 conversion.

Files

• video_resize.py — Main script for resizing videos with audio and bitrate options.
• mkv2mp4.py — Script for converting MKV files to MP4.

Notes

• Make sure FFmpeg is installed and accessible from your command line.
• The scripts display a progress bar and estimated time remaining during processing.
