Step 2: Enable and configure the device settings by clicking the Device 0 button.
Step 3: The Encoding window appears ( Figure 4-2 ). Choose the video input format.
There are multiple video format options, but only two options are for the
HDC-4x Series . They are:
ƒ
1920x1080 (60p) (6000kps – 30000kps)
ƒ
1280x720 (60p) (4000kps – 24000kps)
NOTE:
Which video format to choose depends on the video input resolution and the
selected mode set by the HDC-4x Series rotary switch. If the selected mode
supports 720p resolution, select 1280x720 (60p) despite of what the video
input resolution is. If the selected mode supports 1080p resolution, select
1920x1080 (60p) .
If the selected mode supports 720p or 1080p resolution, the decision is made
by the video input resolution.
ƒ
Select 1280x720 (60p) if both width and height numbers of the video
input resolution are less than 1280 and 720 . For example: 800x600.
ƒ
Select 1920x1080 (60p) if either width or height number of the video
input resolution is greater than 1280 or 720 . For example: 1024x768.
To understand what resolutions the modes set by the rotary switch support,
please refer to Table 2-2 .
The user can also refer to Appendix B for tables of the supported input
resolution and the corresponding video format to select.
Step 4: Configure the encoding settings ( Figure 4-2 ), including encoding file directory
(click Ref button to choose the directory), rate control (CBR or VBR) and video
encoding bitrate (must be in the range of video format). When “CBR” is selected,
the “Bitrate” text box is displayed. When “VBR” is selected, the “Average bitrate”
