[Video] Setting Video Size, Quality and Frame Rate

Solution

[Video] Setting Video Size, Quality and Frame Rate

The following can be set here.

• JPEG

Set the video quality, size, maximum frame rate and upload size in JPEG.

• H.264

Set the bit rate, video size and capture frame rate in H.264.

• On-screen display

Set time, character string, etc. displayed over images

 

(1) [Video Quality]

Select a desired video quality from 1 to 5 (5 levels) for videos transmitted at each video size in JPEG. Greater values have higher quality.

(2) [Video Quality: Digital PTZ]

Select a desired video quality from 1 to 5 (5 levels) for Digital PTZ. Greater values have higher quality.

(3) [Video Size: video Transmission]

Select [320x240], [480x270], [960x540] or [1920x1080] for the size of images transmitted. This becomes the start-up video size used by each viewer.

(4) [Maximum Frame Rate: Video Transmission]

Limit the maximum transmission frame rate per second to reduce the viewer load. The maximum is 30 frames/sec. Enter a value of between 0.1 and 30.0.

(5) [Video Size: Upload / SD card]

Select [320x240], [480x270], [960x540] or [1920x1080] for the size of images when using the upload function or when recording to an SD card. Use [Video Record Action] in the [Event] menu to specify the destination of a video recording (upload or SD card recording).

 

(1) [Bit Rate Control]

Select [Do not use bit rate control] or [Use bit rate control].

Select [Use bit rate control] when [Video Format] under [Upload] is set to [H.264] or when [Video Format] under [Memory Card] is set to [H.264].

(2) [Target Bit Rate (kbps)]

If [Use bit rate control] is selected in (1), select [64] to [8192] (total 13 levels) for the target bit rate.

(3) [Video Quality]

If [Do not use bit rate control] is selected in (1), select a desired quality from 1 to 5 (total 5 levels) for H.264 video transmission. Greater values have higher quality.

(4) [Video Size]

Select [480x270], [960x540] or [1920x1080] for the size of video transmitted.

(5) [Frame Rate (fps)]

Select [30], [15], [10], [6], [5], [3], [2] or [1] (fps) for the frame rate of video transmitted.

(6) [I Frame Interval (sec)]

Select [0.5], [1], [1.5], [2], [3], [4] or [5] for the I frame interval (sec) for H.264 video.

 

Important

• When the SD card recording and upload settings are configured, the following restrictions apply.

- Only [Use bit rate control] can be selected for [Bit Rate Control].

- Only [3072] or less can be selected for [Target Bit Rate (kbps)].

- Only one of [0.5], [1], and [1.5] can be selected for [I Frame Interval (sec)].

• Network load will increase if a larger video size is set or higher video quality and target bit rate are set, as this increases data size per frame. As a result, the following could occur:

JPEG: The frame rate may drop

H.264: Video may be temporarily disrupted

• Block noise may become noticeable if a large video size and low target bit rate are set.

• The data size may increase depending on the type or movement of the subject. If the frame rate remains low or other undesirable conditions continue for a prolonged period, lower the video size or quality setting.

• If you are using RM-Lite, it is necessary for you to set [I Frame Interval (sec)] as shown below depending on the value selected for [Frame Rate (fps)] in [H.264].

• Note that if you are using included RM-Lite, the hard disk usage will also be affected during recording.

 

(1) [Date display]

Select whether to enable date display over images. If [Enable] is selected, date information will be displayed over images.

(2) [Position of date display]

Select [Upper left], [Upper right], [Lower left] or [Lower right] for the position of date display information.

(3) [Format of date display]

Select [YYYY/MM/DD], [DD/MM/YYYY] or [MM/DD/YYYY] for the format of the date display.

(4) [Time display]

Select whether to enable time display over images. If [Enable] is selected, display time information will be displayed over images.

(5) [Position of time display]

Select [Upper left], [Upper right], [Lower left] or [Lower right] for the position of time display information.

(6) [Text display]

Select [Display nothing], [Display designated string] or [Display camera name] for the text string to display over images. If [Display designated string] is selected, the [Text string display] set in (8) will be displayed.  If [Display camera name] is selected, the text string set in [Camera Name (alphanumeric characters)] under [Camera] will be shown

(7) [Position of text display]

Select the position of text display from [Upper left], [Upper right], [Lower left] or [Lower right].

(8) [Text string display]

If [Display designated string] is selected in (6) [Text display], set a text string up to 15 alphanumeric characters to be displayed over images.

(9) [Color of text]

Select [Black], [Blue], [Cyan], [Green], [Yellow], [Red], [Magenta] or [White] for the color of text to be displayed over the image.

(10)[Color of text outline]

Select [Black], [Blue], [Cyan], [Green], [Yellow], [Red], [Magenta] or [White] for the color of text outline.

(11)[Color depth of text and outline]

Select [Fill text and outline], [Make text only transparent], [Make text only translucent] or [Make text and outline translucent] for the color depth of text and outline to be displayed over the image.

 

Important

The on-screen time display is not suitable for usage where high reliability is required. Use as reference information only where utmost and constant reliability is required for surveillance

Note

  • The on-screen time display may not correspond with camera time by several seconds

  • Depending on video quality settings, on-screen display may become difficult to decipher. Set after confirming appearance on actual images.
