MJPEG encoder CBR mode

Dear Team,

Could you please check below customer's setting for CBR mode in MJPEG encoder?

They are using MJPEG encoder v1.00.15.00 by integrating it on DVR RDK v4.01, and their HW is DM8167.

When they applied similar settings to H.264 encoder, They found 362.28kbps, but they found 8364.73 kbps in MJPEG encoder. Could you please check why the bitrate is too high in MJPEG encoder ?
