define ".mp4" - that can be anything - proper H264 videos are no problem 
on *any* browser these days

for mp4 and broad client support you need h264 baseline with AAC audio 
and when possible use .m4v as extension - just because a random browser 
at a random point of time plays a chimere like MP4+FLAC audio don't mean 
that it is wise to create such files
