Answer 1

I believe that MP4 with code H.264 is the best to follow, referring to the last link below

I have made some research however I'm stilll looking for the best, but for now

• http://www.indianprice.com/mobiles/articles/272-best-video-format-for-cell-phones.html it says 3gp more popular for old ones

• http://www.freemake.com/blog/put-videos-onto-any-mobile-phone-how-to/ it says MP4 is already the most supported by the following settings video format: MP4

  • video codec: H.264 or MPEG4
  • audio codec: AAC or MP3

• http://en.wikipedia.org/wiki/HTML5_video | That's the best reference to rely on to compare and apparently its H.264 codec
