Follow these steps to troubleshoot problems.

1If the Resolution, Color format and Quantization of the captured signal is consistent with those of the input signal?

USB Capture (Plus) Family

  1. Open the utility software USB Capture Utility V3.
  2. In the Info tab page, view the Video signal format, which consists of the resolution and frame rate of the input signal.
  3. In the Video tab page, view the Color format and Quantization in the INPUT section.
  4. In the Video tab page, set the Color format and Quantization in the CAPTURE section to the value of the same properties in the INPUT section.
  5. In your video capture software, set the Resolution, Color format (if available) and Quantization (if available) of the captured signal to the value of the same properties of the input signal.

Pro Capture, Eco Capture Family

  1. Call the driver panel of capture card.
  2. In the Video tab page, view the Input signal format, Color format, and Quantization in the Input section. The input signal format is displayed next to the Input label, and includes the resolution and frame rate of the input signal.
  3. In the Video tab page, set the Color format and Quantization in the Capture section to the value of the same properties in the Input section.
  4. In your video capture software, set the Resolution, Color format (if available) and Quantization (if available) of the captured signal to the value of the same properties of the input signal.

2If the captured image is scaled in the video capture software?

If video capture software allows users to set the scaling, make sure the scale factor is 100%.

3If the input signal is interlaced signal?

USB Capture (Plus) Family

  1. Open the utility software USB Capture Utility V3.
  2. In the Info tab page, view the Video signal format. If the video signal format contains "p", the input signal is a progressive scan signal; if it contains "i", the input signal is a interlaced scan signal.
  3. For interlaced scan signal, open the Video tab page, and then set Deinterlace to Weave, i.e. no deinterlacing.
