I would like to play full-screen videos as a background in one of my apps. The problem is that videos take up a lot of space. What resolution and format is most suitable for ios apps? The main criteria are file size & loading time.

The supported video types are mentioned at the Apple docs:

iPhone OS provides support for full-screen video playback through the Media Player framework (MediaPlayer.framework). This framework supports the playback of movie files with the .mov, .mp4, .m4v, and .3gp filename extensions and using the following compression standards:

  • H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
  • H.264 video, up to 768 Kbps, 320 by 240 pixels, 30 frames per second, Baseline Profile up to Level 1.3 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
  • MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats

  • Are you using the video which has been recorded by your application? It's possible to manage the quality of the video before it has been recorded, read about video presets, it will help you to manage the video quality, its size and resolution as well. – Pradeep Singh Feb 26 '16 at 14:08
  • Thank you! No, I will add a custom one. Hmm.. 640 by 480 pixels is pretty bad quality. on ihone 6s+ that wouldn't look good. – potato Feb 26 '16 at 14:09
  • The question was what are the preferred formats, not supported formats, like Apple has some preferred audio formats mentioned https://developer.apple.com/library/ios/documentation/AudioVideo/Conceptual/MultimediaPG/UsingAudio/UsingAudio.html#//apple_ref/doc/uid/TP40009767-CH2-SW28 – Saad Aug 05 '16 at 10:54
