Modify Deinterlace mode

How to modify the de-interlacing mode?

By default, the de-interface mode is Blend top & bottom field, users can manually change it to other modes.

△ Deinterlacing is a process of converting interlaced video into a progressive form with the frame number reduced by half after processing. The process is done by FPGA, causing 0 CPU usage. For example, the input signal is a 60 field/s interlace signal, the device delivers a 30 frame/s progressive signal after processing.

Procedures

Step 1. Choose a de-interlace mode from the drop-down menu in CAPTURE > Deinterlace in the Video tab.

• Weave: takes pairs of fields and puts them together (every other line) to one frame. The result is the same as no deinterlacing. This mode is used when users want to capture the original video.
• Blend top & bottom field: blends the top and bottom field together.
• Top field only
• Bottom field only

Crop input	Adjusts the capture area of the input video. Unwanted parts can be cropped out and the remaining part captured.If the box is ticked, users can set the cropped dimensions by clicking on the arrows for each of the four values.The default value is the input dimension. If the set value is beyond the device's capability, it will show the max supported the value of the device.
Color format Shows the color space for capturing. If the box is ticked, other color spaces can be chosen.
Quantization	When only a limited number of colors can be displayed due to memory or other restrictions, users need to reduce the color of the image.Options include:Full range (0-255)Limited range (16-235)
Saturation	Shows the 8-bit saturation range options of the input signal. If the box is ticked, the saturation range can be chosen from:Full range (0-255)Limited range (16-235)Extended gamut (1-254)
Deinterlace	The default value is Blend top & bottom field. The range of values:Weave: Combines the top field and bottom field into a frame without any other process. Usually used to capture the original data.Blend top & bottom field: Merges two fields together and deinterlaces via FPGA to ensure a CPU-free video processing.Top field only: Copy the top field data in vertical direction as a full frame.Bottom field only: Copy the bottom field data in vertical direction as a full frame.Deinterlacing is a process of converting interlaced video into a non-interlaced form, and half size the frames after processing. For example, the input signal is a 60 field/s interlace signal, the device delivers a 30 FPS progressive signal after processing.

Specific effect	By default, no specific effect is used. Video effects are offered as follows:FlipMirrorFlip and Mirror

Setting Volume

The Volume tab shows controls for all the audio devices, which can be manually adjusted with immediate effect. A right or left click of the mouse on either the slider track or the numeric value text will set the level to the nearest indicated value quickly (e.g. 0dB, -10dB, etc).

Volume settings in the Utility V3 are synchronized with the system volume control.

PLAYBACK RECORD

The Playback section acts as a monitor mixer for the headphone output socket, and comprises three controls, with icons for Headphones, HDMI & Computer. The HDMI & Computer controls can be used to set the relative levels of each of those sources in the mixed output, whilst Headphones (far left) acts as the master volume control. It is not possible to include the Mic input in the monitor mix sent to the Headphone output.

Note that setting all controls to maximum risks signal clipping if the sources contain high level signals. It is safer to keep individual channel gains to the values of '0' or lower unless extra gain is specifically required.

There are two volume level controls, for the Mic and HDMI Recording devices. There is no control here for the Computer input, although by default there is 0dB gain (ie. the input will be the same digital level as the audio sent to the Headphones Playback device).

Note that there is 6dB of digital gain available, so that volume settings above '0' risk digital clipping of high level audio peaks (i.e. with the volume control set to maximum, audio input signal peaks above -6dBFS will get clipped). The Mic input can also act as a mono line-level input (giving 0dBFS from \~0dBV with the control at '0'), and has \~45dB of gain for handing mic-level signals.
