oCam Advanced Settings - Mouse Cursor Effects - Highlight Effects
Click Tools - Options on the oCam main menu, then open the Effects category to check the Highlight Effect settings.
The Highlight Effect is used to help viewers immediately recognize the current position of the mouse cursor while watching a video.
The options are described below.
Color
- This is the color applied to the highlight effect. It is set to yellow by default.
Size
- When the highlight effect is enabled, a semi-transparent circle is drawn around the mouse cursor. This option sets the size of that circle. It is set to 90 by default.
Soft Edge
- The higher this value becomes, the softer the edge of the circle appears.
Opacity
- The lower this value is, the more transparent the circle becomes.
Preview
- Lets you preview the mouse effect you have configured.
If the opacity value is set too high, the highlight effect may cover the part of the screen where the mouse is located. For that reason, it is best to use an appropriate opacity setting.

What are codec and digital container format?
What are codec and digital container format?
Although you generally do not need to understand these two terms to use oCam, you should know them if you want to use the extended functions in oCam.
Codec and digital container format have multiple meanings, but here we explain only the meanings used for oCam.
First, a digital container format refers to common container formats such as AVI, MP4, and MOV.
Wikipedia has more detailed explanations.
A container format, also called a wrapper format, is a metadata file format that defines how different data components can coexist within a computer file.
In simpler words, AVI, MP4, MOV, FLV, and similar formats refer to the file structure that determines how video or audio data is stored.
And the data stored in that container is related to codecs.
The definition of a codec is described in Wikipedia as follows.
http://ko.wikipedia.org/wiki/%EC%BD%94%EB%8D%B1
A codec (short for coder-decoder) is hardware or software that can encode and decode, or both, a data stream or signal. It also refers to the algorithm used to do so. In telecommunications, the term originally referred to sender and receiver devices, known as a โcoderโ and โdecoder,โ which originated in 1980s America.
A codec includes software that compresses or decompresses data using compression functions, or devices and software that convert media such as sound and video into different formats.
To explain more simply, in current oCam usage, codecs are used to encode screen data into video, generating encoded video and audio data, and this data is saved as a file according to the container format selected in oCam.
Examples of codecs that we commonly know are XVID, MPEG-1, MPEG-2, MPEG-4, and H264.
For example, if there is a file with an AVI extension, then the digital container format is AVI, and the stored video and audio are saved using the AVI-defined structural format.
At that time, the stored video data may be H264, MPEG-4, and so on, while the audio data may be MP3, PCM, etc.
