Yea, HandBrake is good. If you don't like to convert movies to iPad-format, download AVPlayerHD from iOS AppStore. It can even streaming. You can add movie even from another app in your iPad ("Open with..."), so no computer needed. If you want add movie from computer, you can use File-Sharing in iTunes or by 3rd party apps, like iMazing. AVPlayerHD suppports subtitles too.
