What changes when you convert VOB to MP4
The video stream has to be fully re-encoded: VOB typically carries MPEG-2, and MP4 expects H.264. That means a real transcode, so allow for processing time and a small generational quality cost.
MP4 is built for streaming and progressive download, so the result starts playing before it has fully loaded, which the source format does not do well.
Compatibility is the main win here: MP4 plays natively on 6 more of the platforms we track than VOB does, so the result works without asking anyone to install a player.
At 1080p, VOB typically runs around 6.5 Mbps while MP4 sits near 13 Mbps, which is the main driver of the size difference you will see.
