Interpretation Change rate control of MPEG-4. Rate control can be set to cbr or vbr. Bitrate is controlled to be
constant in the case of cbr (Constant Bitrate). In the case of vbr (Variable Bitrate), bitrate can be larger by input image.
If vbr is set, frame rate of MPEG-4 becomes 30fps.
The change is saved by the API, encode(2).status=save. If the change is not saved, the setting is restored by reboot.

Setting MPEG-4 Frame Rate Setting for VN-V685/686/686B
Format /api/param?encode(2).framerate=data
Example /api/param?encode(2).framerate=30
Example of response encode(2).framerate&202 Accepted(encode(2).status=save)
Interpretation Change frame rate of MPEG-4. Specify 30, 25, 15, 10, 7.5, or 1. If vbr is set to MPEG-4 rate control,
frame rate of MPEG-4 becomes 30fps. If I-Frame interval is not 30, 60, 120, 150, 180, 210 or 240, real frame rate
becomes larger than the setting. Refer I-Frame interval API for details.
The change is saved by the API, encode(2).status=save. If the change is not saved, the setting is restored by reboot.
