Sharing my experience: - As a beginner, it was difficult for me to understand video recording formats. XAVC S HD - an attempt to get closer to higher resolution cameras, unreasonably consumes a lot of memory. If you want maximum clarity and quality, the best option is to select a frame rate of 50p (50 full frames per second), while the frame size and compression ratio are not selected - it is the only one. The remaining options to save space are 50i frame rate (that's 50 fields per second, that is, interlaced mode) and options in the "REC Mode" menu. - Indoors, the automatic white balance is bad - you have to put your hands on a sheet of white paper. - Actively use the "Scene Selection" menu. In the mode of a simple automaton, a completely unsatisfactory result can be obtained. - I was advised not to use the rest of the manual parameters, arguing that it would not be possible to achieve better quality.
