What is XAVC S?
XAVC S is a recording format that allows high-resolution images, such
as 4K, to be highly compressed with MPEG-4 AVC/H.264 and
recorded in the MP4 file format. High image quality will be obtained
while keeping the data size within a certain level.
• Bit-rate indicates the quantity of data recorded in a certain period.
