I'm going to guess that this is a video format.
Here is what is approved:
H.264 video up to 720p, 30 frames per second, Main profile level 3.1 Audio: AAC-LC up to 160 Kbps, 48 โโkHz, stereo File types: .m4v, .mp4 and .mov
MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Audio profile : AAC-LC up to 160 Kbps per channel, 48 kHz, stereo File types: .m4v, .mp4 and .mov
Miro can help you, as it has the โfor iphoneโ option, which sets up the video just right.
