DVD VOBs use MPEG-2 interlaced video at standard definition — incompatible with most mobile devices' hardware decoders. The Mobile Video preset produces H.264 MP4 with Baseline or Main Profile at resolutions and bitrates optimized for mobile screens and cellular networks, targeting universal playback across iOS, Android, and all mobile platforms.

Mobile devices generally cannot hardware-decode MPEG-2 from VOB files. Even if software decoding is available (via VLC), it drains battery and causes stuttering. The Mobile preset ensures smooth hardware-accelerated playback on every smartphone and tablet.

DVD's interlaced video also displays poorly on mobile screens. The conversion handles deinterlacing and aspect ratio correction automatically.

FFmpeg deinterlaces MPEG-2, resolves DVD aspect ratio, and transcodes to H.264 Baseline Profile Level 3.1 with AAC-LC audio. Resolution targets 480p (matching DVD native) or 360p for bandwidth-constrained scenarios. Bitrate is 1-3 Mbps with constrained VBR. AC3/DTS surround is downmixed to stereo. Faststart flag enables progressive mobile playback.

Yes. H.264 Baseline Profile in MP4 is the universal mobile format, supported by every smartphone from 2010 onward.

At 2 Mbps H.264, a 2-hour DVD is about 1.8 GB. At 1 Mbps, about 900 MB. Both look good on phone screens.

Yes. At normal phone viewing distances, 480p appears sharp on screens up to 6 inches. Most people cannot distinguish 480p from 720p on phones.

Phones output stereo. DVD 5.1 is downmixed to stereo during conversion and sounds natural through earbuds and phone speakers.

Short clips under 16 MB work for standard WhatsApp sharing. Full movies should be shared as documents (2 GB limit).
