The Sony AX-100 camcorder records 4K and HD movies in XAVC S, a consumer friendly format based on the XAVC codec developed for 4K/HD and professional use, which uses MPEG-4 AVC/H.264 for video compression and linear PCM for audio compression, while saving files in a MP4 wrapper. However, if you want to compress the XAVC S videos from Sony AX-100, it may not as smooth as you think. 
“I was using Wondershare to convert 4K XAVC S files, but there was something amiss in the compression and it was not behaving well. So, I started searching for an alternative. After downloading Pavtube HD Video Converter for Mac trial version and testing it with several file types, all worked fine and so I purchased it.”
