I've searched the forum and found some fragmented mentions of this but nothing definative. I checked and the mini2 has the same processor as the mini 3 and iPad Air... so that doesn't seem to be the issue. Sometimes it works once and sometimes it works three times but it ecentually always freeze when I swith back and forth between stills and video... this is essential to my work so I need to either fix it or find a more stable tablet for the app.
