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.

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.
Today's News/Tips
Where are the recorded video files saved, and how can I change the save location?
In oCam, recorded video files are automatically saved to the folder you specified as the save path.
By default, oCam saves files to the default folder configured on your computer.
To check this folder, first run the oCam program and go to the main screen.
Click the Open button on the main screen, and the folder where recorded video files are saved will appear.
Clicking this button automatically opens Windows Explorer so you can check the folder directly.
If you want to change the save path, click the Settings button on the oCam main screen.
When the Settings window opens, go to the Save tab at the top and find the save path setting option.
You can change the path by clicking here and selecting a desired folder.
After saving the changed path, all future recorded video files will be saved to the new location.
In addition, setting the save path to a folder you use often makes file management much more convenient.
