Frequently Asked Questions
Will converting VOB to OGV reduce video quality?
There will be some quality loss due to transcoding from MPEG-2 to Theora codec, but with proper settings, the visual difference is minimal while achieving much smaller file sizes and better web compatibility.
Can I preserve multiple audio tracks when converting to OGV?
OGV supports multiple audio streams, so you can preserve different language tracks or audio formats from the original VOB file, though they’ll be converted to Vorbis audio codec.
Are subtitles maintained during VOB to OGV conversion?
Subtitle preservation depends on the type – DVD bitmap subtitles may need separate extraction, while text-based subtitles can often be maintained or converted to compatible formats within the OGV container.
What’s the typical file size reduction when converting to OGV?
OGV files are typically 50-70% smaller than original VOB files due to more efficient Theora video compression compared to MPEG-2, while maintaining acceptable quality levels.
Can all web browsers play OGV files natively?
Most modern browsers support OGV playback through HTML5 video elements, though some browsers may require fallback formats like MP4 for complete compatibility across all platforms.
Is OGV format suitable for high-definition content?
Yes, OGV supports HD resolutions and can handle the full resolution of DVD content (720×480/576) effectively, with Theora codec capable of encoding higher resolutions if needed.
How does OGV compare to MP4 for web use?
OGV is completely open-source and royalty-free, making it ideal for open platforms, while MP4 has broader device support. OGV offers good compression and quality for web streaming applications.
Can I convert encrypted DVD VOB files to OGV?
Convertify can only process unencrypted VOB files. If you’re converting from personal DVDs, you may need to use DVD ripping software first to create unencrypted VOB files for conversion.
