Technical Details
Advanced Codec Transformation
Converts MPEG-2 video streams to VP8 or VP9 codecs while transcoding AC-3, PCM, or DTS audio tracks to Vorbis or Opus format. The process intelligently handles interlaced content and maintains aspect ratios during the conversion.
Container Format Optimization
Transforms the DVD’s program stream container into the modern Matroska-based WEBM container, enabling features like adaptive bitrate streaming, chapter preservation, and metadata embedding for web applications.
Intelligent Quality Scaling
Automatically analyzes source bitrates and resolution to optimize output settings. Supports resolution scaling from DVD’s 720×480/720×576 to modern web standards while maintaining proper deinterlacing and frame rate conversion.

Frequently Asked Questions
Will converting VOB to WEBM reduce the video quality significantly?
Modern VP9 encoding in WEBM format is highly efficient and can maintain excellent quality while reducing file size by 60-70%. The quality loss is minimal and often imperceptible, especially when using appropriate bitrate settings for your intended use.
Can I convert copy-protected or encrypted VOB files?
Convertify can process standard VOB files, but copy-protected DVDs with CSS encryption require the protection to be legally removed first using appropriate software before conversion. Always ensure you have the right to convert the content you own.
How do I handle multiple VOB files from a single DVD?
DVDs typically split content across multiple VOB files (VTS_01_1.VOB, VTS_01_2.VOB, etc.). You can either convert each file individually or use batch processing to convert all files simultaneously, then merge them if needed using video editing software.
Will the converted WEBM files play on all devices?
WEBM has excellent support in modern browsers (Chrome, Firefox, Opera, Edge) and many mobile devices. However, some older devices or certain media players may have limited WEBM support. For maximum compatibility, you might also want to create MP4 versions.
How much smaller will my files be after converting to WEBM?
File size reduction varies based on content and quality settings, but typically ranges from 50-80% smaller than the original VOB files. A 1GB VOB file often converts to a 200-400MB WEBM file with comparable visual quality.
Can I preserve chapter information and multiple audio tracks?
WEBM format supports chapters and multiple audio tracks, but the level of preservation depends on how the original DVD was authored. Basic chapter markers can often be maintained, while complex menu structures will not transfer to the WEBM format.
What’s the best quality setting for web use?
For web streaming, aim for bitrates between 1-5 Mbps depending on resolution. 720p at 2-3 Mbps provides excellent quality for most web applications, while 1080p at 4-5 Mbps is ideal for high-quality presentations or detailed content.
How long does it take to convert a typical DVD?
Conversion time depends on your computer’s processing power and the quality settings chosen. A typical 2-hour DVD might take 30-90 minutes to convert on a modern computer, with faster CPUs and hardware acceleration significantly reducing processing time.
