Optimizing video performance
For the best possible video quality, adjust the video resolution, compression, and frame rate.
Context
The Video Encoder page allows you to define the main parameters for live feed, video recording and playback.
Important
Do not modify System Setup parameters while you are using Live Feed mode.
Procedure
1 Select the Setup icon.
The icon is located under the Main menu.

3 Click the Video Encoder tab.
4 If required, change the Resolution.
This parameter is used to determine video resolution during the live feed and recording.
The resolution provided by the camera is higher that than the options you are provided with here. However, the length and quality of your trawl cable may have a negative effect on the video feed, and reduce the video quality. To reduce the strain, you may need to reduce the resolution, as this will reduce the amount of video data to be transferred from the camera up to the computer.
5 If required, adjust the video Compression.
This parameter allows you to define the video compression.
A higher integer provides higher compression, but will also introduce more lag in the video feed. For best video quality, use a low number. The default value is 30, which is a good trade-off.
6 If required, change the Frame Rate.
Frame rate (also known as ‘frame frequency’) is the frequency (rate) at which an imaging device produces unique consecutive images called frames. Our brain can process 10 to 12 separate images per second, perceiving them individually. If you reduce the frame rate, you will see a loss of quality in the video, but the file size will be smaller when you are making a recording.
Unless you have special requirements, use the default value of 15 frames per second.
