VOB files are DVD-Video files, usually stored in the root of the VIDEO_TS folder. They contain MPEG-2 video and audio streams and are quite large in file size. You can convert VOB to H264 (a more popular and advanced video compression format), to make videos more accessible across platforms while reducing video size. Below, we provide a nice and simple VOB converter program that can efficiently convert VOB files to H264 videos. Please read for more details.
Tips. H264 is a codec format different from the container format like VOB. The common container formats that support H264 are MP4, MKV, MOV, and AVI.
WonderFox DVD Video Converter is a powerful converter program designed to convert DVD files and digital videos. It supports DVD VOB files and can convert VOB to H264 format very quickly. Besides, it can convert VOB to MP4, VOB to MPG, VOB to MP3, and 300 more formats and devices. It’s got a built-in video editor that you can use to edit VOB videos, like cut, crop, and merge VOB. It is also a DVD decrypter to copy protected DVDs, VOB files, and ISO images.
Start WonderFox DVD Video Converter on your Windows PC. Click the arrow next to “Load DVD” > “Load DVD Folder” > add your VOB files. Or you can click the upper-left “Add Files” to import a single VOB file.
On the right side of the program, hit on the format image to open the output format page. Head to the “Video” section and select “H264” (saved in the MP4 container by default) as the output profile. Alternatively, you can select MP4, MKV, MOV, or AVI, the formats that support the H264 codec, and then go to the lower-right “Settings” > change video encoder to “H264” manually.
Now, click the bottom three-dot button to set an output folder and hit the “Run” button to start the conversion. It should take some time depending on the source file size. Normally, with hardware acceleration, a 2-hour-long VOB video can be converted to H264 in 10 - 20 minutes.
Since VOB files are MPEG-2 videos, converting MPEG-2 to H264 is a transcoding process that will result in quality loss inevitably. But such loss is unnoticeable to the eye. If you want lossless conversion, you can choose MPG as the target format as MPG supports the MPEG-2 codec.
Generally, unless your DVD VOB files are copy-protected, it is legal to convert DVD VOB videos. But the law on DVD copying varies in different regions. You’d better check your local law before you convert or rip any DVD files.
If the VOB file is small and unencrypted, sure you can try converting the VOB file to H264 online. Basically, any online video converter today supports H264 conversion. However, if the VOB file is a part of the DVD files, you may fail to convert it online due to the protection and size limit.
