By default, these play in the iPad’s Videos app. The iPad does have limitations within these formats. For example, H.264 videos are limited to 1080 pixels and 30 frames per second. MPEG-4 videos are limited to 2.5 Mbps and 640 by 380 pixel resolution at 30 frames per second. Videos exceeding these limits may not play correctly on an iPad, or may not play at all. Although the iPad does support stereo sound, you will need headphones or external speakers to hear it. The built-in speaker provides only mono playback.
