30 fps. The unit “fps” stands for “frames per second”.
Note: The frame rate is up to 15 fps at 1280x1024, and up to 30 fps at 640x480. However,
if you would like choose frame rate over 15 fps, the IMAGE SIZE of all three video
compression format (H.264/MPEG-4/MJPEG) should set euqal to or smaller than 640x480
at the same time.
Quality:
z
Auto: The quality and bitrate will be adjusted automatically according to the frame rate.
z
Fixed Quality: Select the value of quality among Medium, Good, Detailed and Excellent.
Fixed Bitrate:
Set the bitrate of H.264 image transmission for a line. Select one among 64Kbps, 128Kbps,
256Kbps, 384Kbps, 512Kbps, 768Kbps, 1Mbps, 1.5 Mbps, 2 Mbps, 3 Mbps, 4 Mbps, 5
Mbps, and 6 Mbps.
Note: Concerning how to select the suitable image quality for Fixed Quality or Fixed Bitrate,
please refer to the CHAPTER 10. APPENDIX / A. Frame-rate & Bitrate Table.
IP Interval:
It’s the ratio of i-frame & p-frame. Select one among 1, 5, 10, 15, 30, 60, and 120. The ratio
smaller, the streaming smoother.
Note: The IP interval value means a ratio of “ P-frame / I-frame “ in a certain section of
frame sequences. The ratio lower, the live view clear. However, live view will lag if the
bandwidth isn’t big enough. In this situation, you have to choose another bigger IP interval
value to solve the problem.
Note: If Video Clip Format of General Menu (go “Setting → Basic → Camera → General” ),
which is for recording compression, is chosen H.264, the IP interval option will appear
“Auto” automatically and can’t select. The limit is for avoiding damaging the recording
quality of 5 seconds temporary-saved video recorded on FTP server.
