Interpretation Change the file size setting of JPEG. The unit of set values is in KB. VN-V686 will perform rate
control with this file size as the target.
When frame size is VGA, setting between the range of 10k to 100k is possible. When frame size is QVGA, setting
between the range of 3k to 33k is possible.
When VFS (VariableFileSize) is specified for rate control at the WEB setting page, 7 levels will be available for
selection. Each of these choices corresponds to the file sizes as follows.
Level
File Size Setting for VGA
File Size Setting for QVGA
