AVCHD, jointly developed by Sony and Panasonic, is primarily used for high definition consumer camcorder (from wiki). Generally, AVCHD video is encoded by H264 or MPEG-4 codecs, with the result that the file size of AVCHD is larger than the file encoded by HEVC/H265. Of course, AVCHD larger file size is one side that you wanna convert to HEVC. On the other hand, AVCHD compatibility is the final trigger for your abandon of AVCHD format.
Case 1: you go to the warm Phuket to spend the cold winter. The clear blue sky, bright sunshine, wide sandy beaches, limestone caves, distinctive rock formations and the passionate local residents all leave a distinctive impression on you. You use your newly-bought HD camcorder to record these great sceneries and lovely faces as a life sweet memories. You return your city after the tour is over and plan to transfer the recorded 4K AVCHD videos from internal SD card to your iPad Pro, yet your iPad supported video formats list doesn't include .avchd.
Case 2: you make a special trip to Oklahoma City to watch the passionate NBA match game between Thunder and Golden State Warriors and use your Sony camcorder to capture amazing highlights of your favorite NBA player (Westbrook, Curry or Paul George). When you come back home, you wanna transfer these Sony 4K AVCHD video clips to your Samsung TV via USB for a reveiw with your kids, but Samsung TV doesn't recognize AVCHD videos.
Above all, the best solution is to convert AVCHD to HEVC MP4 from H264 or MPEG-4 codec. Thus, you can not only solve the AVCHD file large size issue, but also easily tackle AVCHD video not playing on iPad iPhone HDTV problems.
