Optimal Video Formats

I saw in a previous post that videos should be at a maximum 10fps when converted. Is there an optimal overall format? MKV? MP4? And are there any other stats to be followed other than the FPS? THANKS!

I ment Mb/s not FPS

The max speed the wifi chip in the WMD can stream at is 10Mb/s if you stay below that you should be good. Keep in mind that is 10Mb for all streams. If you want to stream out to 5 devices the video should be 2Mb/s or less. 

As far as file type that is more for the host. For iOS MP4 is probably easiest.
