Hi Afonz, the Alcatel One Touch Fierce supports .3gp and .mp4 video which are quite common even on desktop PCs. So if you have mp4 videos on your computer, for instance, you wouldn't have to change them into anything else to be able to play them on your phone. In case your videos are in some other unsupported format, just download a compatible video player by searching for "android [insert video format here] player" on either the Google Play store or on Google itself. I hope that answered your question!
