WebM uses VP8/VP9/AV1 video — codecs that iPads cannot hardware-decode natively (Safari added VP9 support in iOS 14, but hardware decode varies by model). The iPad Video preset produces H.264/H.265 in MP4/MOV that leverages the iPad's dedicated hardware decoder for smooth playback, proper color reproduction, and optimal battery life.

While newer iPad Pro models with M-series chips can software-decode VP9, older iPads and iPad mini models cannot play WebM at all. Even on capable devices, VP9 software decoding drains battery faster than H.264 hardware decoding. The iPad preset ensures universally smooth playback across all iPad generations.

Photos app, Videos app, and AirPlay all work reliably with H.264/H.265 — WebM support in these native apps is inconsistent.

FFmpeg decodes VP8/VP9/AV1 video and Opus/Vorbis audio from WebM, then transcodes to H.264 High Profile Level 4.1 or H.265 Main Profile with AAC-LC audio. Resolution is preserved up to the iPad's display resolution. Bitrate targets 5-12 Mbps depending on resolution. The moov atom is front-loaded for instant playback.

iPad Pro with M-series chips can play VP9 WebM in Safari. But Photos app, AirPlay, and other native apps have inconsistent support.

With H.264, typically 20-30% larger at comparable quality. H.265 produces similar or smaller files than VP9 WebM.

H.265 for iPad Air 2 (2014) and later — smaller files at same quality. H.264 for maximum compatibility including older iPads.

AirDrop, iCloud Drive, iTunes file sharing, or any file transfer app. The converted file imports directly into Photos.

Yes. H.264/H.265 in MP4/MOV streams perfectly via AirPlay to Apple TV and compatible speakers.
