When you update the software of your camera to the latest version, you will be able to shoot movies with Imaging Edge Mobile (PlayMemories Mobile successor).
NOTE: If you are using a DSC-HX400V/HX400 or DSC-HX60V/HX60, you must download and install Smart Remote Control Ver. 3.10 or later, which is one of the PlayMemories Camera Apps, in addition to updating the software of your camera.
