9. Recording Motion Pictures
When [MP4] is selected
• What is bit rate
This is the volume of data for a definite period of time, and the quality becomes higher when the
number gets bigger. This unit is using the “VBR” recording method. “VBR” is an abbreviation for
“Variable Bit Rate”, and the bit rate (volume of data for definite period of time) is changed
automatically depending on the subject to record. Therefore, the recording time is shortened
when a subject with fast movement is recorded.
∫ About the compatibility of the recorded motion pictures
Even when a compatible device is used, recorded motion pictures may be played back
with reduced picture and sound quality, or they may not be played back.
Also, recording information may not be displayed correctly. Use this unit to playback in
such case.
•
If you want to use another device to play back motion pictures recorded in [FHD/28M/60p],
[FHD/24M/30p], [FHD/24M/24p] of [AVCHD] or if you want to transfer them to the device, a PC
installed with “PHOTOfunSTUDIO” or a compatible Blu-ray disc recorder is required.
• For motion pictures recorded with [MP4] set to [4K/100M/30p] or [4K/100M/24p], refer to
“Watching 4K motion pictures on a TV/ Saving 4K motion pictures on your PC or recorder” on
