Resolution: If "2592x1944 @15fps" is selected in Input Resolution option,
you can select 2592x1944, 2048x1536, 1600x1200, 1280x960,
640x480, 320x240, or 176x144 here. If "1920x1080@30fps" is selected in
Input Resolution, you can select 1920x1080, 1280x720, 640x480,
320x240, or 176x144 here.
Profile: High profile provides better coding efficiency. Note that some
devises do not support every profile. For example, iPhone4 only supports
Main profile.
(iii) Bitrate Control Mode: In CBR(Constant Bit Rate) mode,
the bitrate keeps consistent all over the video. In VBR
(Variable Bit Rate) mode, the bitrate changes with the
complexity extent of the video data.
VBR provides a better compression way and the file may
be smaller. However, the VBR file size cannot be
predicted. The image may
become broken or lagged when your bandwidth is not
enough for the data quantity you selected.
(iv) Video Quantitative: The quality parameter of VBR. You can
choose 1~10 compression rate. The higher the value is,
the higher the image quality
is.
