Quality Select the JPEG picture quality (rate control mode) and picture quality level.
When "AFS" is selected, encoding is performed such that the target file
size is the average size of multiple JPEG images.
When "VFS" is selected, the quantization table during JPEG encoding
will be maintained and the file size will increase or decrease according to
the input signals. When recording JPEG data to a recorder with a limited
storage capacity, note that the maximum recording time may vary as the
file size fluctuates under this setting.

The chart below shows file sizes for each combination of frame size
and picture quality level.

Select between level 1 and level 7. The picture quality increases when
the level value is small. However, the file size increases (see the table
