To capture and save your first video using Pixelink Capture, follow the steps below:
1. Connect your camera to the computer, and open Pixelink Capture.
2. You can change camera settings like exposure time and frame rate on the Controls tab.
Note: Pixel formats MONO8 and YUV422 are supported for video capture. Pixel format can be changed from the Format drop down, on the Controls tab of Pixelink Capture.
3. Go to the Video tab of Pixelink Capture, and choose the name and location for your saved video file.
4. Ensure the "Match Camera" box is checked, as shown in the following image, so that the playback frame rate of the video matches the frame rate at which the video was recorded. Changing this value may cause videos to appear "sped up" or "slowed down".
5. The "Number of Frames" box determines the length of the video. In the above example, the recorded video would be approximately 4 seconds long. (Or 120 frames / 29.629fps = 4.05 seconds.)
Please note, version 10.4 (and below) of Pixelink Capture limited the Number of Frames to 1000. To record more than 1000 frames, please install the latest version of Pixelink Capture, available for download from our website: https://www.navitar.com/products/pixelink-cameras/pixelink-capture
6. Click the camcorder below the preview window, as seen in the following image, to begin recording a video.
Troubleshooting
Video Capture ROI too Large
This error occurs when trying to capture an ROI greater than 9 MP. Reduce the Region of Interest Size using the drop down menu located above the preview window.
Clip Created, but Required xx% Additional Frames. Consider Increasing Clip Decimation.
This message appears when the host system cannot accommodate the high data capture rate. Pixelink Capture records compressed video, so your host system may require more resources in order to perform the compression at higher capture rates.
In this case, frames that were lost due to slow compression will be replaced by frames recorded later. For example, if you set the recording to 100 frames, but you lose some frames due to the host system compression, it will record additional frames after the original allotted time passes. 100 frames total will still be recorded for the video.
Reducing bit rate should allow your host system to process the frames faster, and record the frames in sequence. Please note that reducing bit rate can also reduce your video quality. You can also enable the decimation factor in the video tab; setting it to any value higher than 1 means that decimation is enabled.
Unsupported Pixel Format
Change Pixel Format to YUV422 for colour cameras, or MONO8 for mono cameras, on the Controls tab.
Please note: As YUV422 and MONO8 pixel formats are not available on polar cameras, video recording is not currently supported in Pixelink Capture for polar cameras.To record a video with a polar camera, select the option to record an Uncompressed video from the Video Capture Tab of Capture OEM.
H264 Insufficient Data Error
This error occurs when you try to capture a video clip that contains less than 20 frames. Please increase the number of frames in your recording and try again.
