How to edit Sony a6500 4K XAVC S video in iMovie?
“Hello guys, my Sony a6500 records 4K UHD (3840x2160p) footage in XAVC S format with MP4 extension. When editing the XAVC S files under iMovie 10.1.7, video is very choppy. Computer is 2011 iMac i7 3.4G, 32G RAM, 500G SSD and OS X Sierra. Does anyone have a similar issue? I’m guessing it’s a computer or iMovie problem? Any insights on this? I would really appreciate any help. Thanks in advance.”

The choppy issue happens probably because you are using a slow Mac machine. Keep in mind that 4K XAVC S footage requires a ridiculous amount of processing power if you want to edit it in its original format, so you’d better convert Sony a6500 4K XAVC S video to Apple InterMediate Codec first before you start editing in iMovie on your old Mac. Apple InterMediate Codec is less hardware intensive than XAVC S (H.264). You don’t need a fancy graphics card and you don’t need a fast computer to edit these transcoded formats. Here is how.
