My .MOV video files taken on ipad do not play on transfer to Macbook Pro.

I have downloaded Photo transfer App 5.11 today to both ipad and MacBook Pro. I transferred photos and videos taken on the ipad by drag and drop from ipad to MacBook Pro 10.9.5 ( the download option did not work at all  for either photos or videos). The photos can be opened (although they have lost their 'info' data. But .MOV are now appear as a 'QT movie' and are a fixed pixelated page only. movies are 300-500 KB sizes.
Thank you for yuor help
