How to Compress VOB Files?
Compressing VOB files involves reducing their size while retaining as much of the original quality as possible. VOB files are natively compressed using the MPEG-2 codec, a lossy compression algorithm optimized for DVD-Video. This compression balances quality and file size, but VOB files are still relatively large compared to modern formats. For instance, a standard VOB file can take up 1GB for approximately 20-30 minutes of video, depending on the bitrate. To further compress VOB files, they can be converted to more efficient formats like MP4 or WebM, which use modern codecs such as H.264 or VP9.
To compress a VOB file convert the File to a More Efficient Forma to reduce file size by up to 50% or more. Tools like HandBrake and FFmpeg are popular options for this task. These tools allow you to select a more efficient codec, such as H.264 or H.265, and adjust settings like bitrate and resolution to achieve optimal compression. If the original VOB file has a high resolution (e.g., 720×480 for NTSC DVDs), lowering the resolution or bitrate during re-encoding can significantly decrease file size while maintaining acceptable quality for specific use cases.
File Compression Using HandBrake
- Download and install HandBrake (free software).
- Load the VOB file into HandBrake’s interface.
- Select a preset, such as “Fast 720p30” or “General > Fast,” to maintain quality while compressing the file.
- Choose the MP4 container and H.264 or H.265 as the video codec.
- Adjust the bitrate or resolution if needed for additional compression, then start the encoding process.
Lossy vs. Lossless
While VOB files are inherently lossy due to MPEG-2 compression, further compression through re-encoding with H.264 or H.265 will also be lossy but more efficient. For scenarios requiring lossless quality, converting the VOB file to a less compressed container like MKV with a high bitrate is an option, though this may not significantly reduce file size.
Compressing VOB files ensures they are more manageable for storage, sharing, or playback on modern devices. By leveraging newer codecs and compression tools, users can achieve smaller file sizes while maintaining excellent video quality for most applications.
