90 mins video quality/datasize
 

Hey guys!

I am creating a website, on which you can view videos from different lectures and speeches, similiar to TEDtalk. The speeches would be about 90 minutes long, mostly unmoved camera and recording. At the most there are some pictures and short movieclips in this speech, but most of the time just static recording of the speaker.
What would be the most effective format of recording in relation to datasize regarding a 90 mins video.
What would be datasize with 720p? Below 720p the quality of viewing would be too bad i presume? what datasize do hd movies for streaming have and which format/codec?

Thank you!

Record in full 1080HD and keep your options open for later.
