How to Capture Images with oCam
Clicking the Capture button on the main screen of oCam immediately captures the screen within the recording area you have set. This feature is very useful when you want to save a precise snapshot of a specific part of the screen. Through oCam's intuitive interface, users can freely adjust the capture area in advance and take screenshots exactly as needed by selecting the full screen, a specific window, or a custom area. This flexibility is especially useful for document work, preparing presentation materials, or for IT professionals who need to record specific UI elements.
Once the capture is complete, oCam saves the image in PNG format by default, providing a sharp, high-quality result. PNG format supports lossless compression, so you can keep clear screenshots without any loss of image quality, and it is compatible with most image editing software and platforms. In the oCam settings menu, users can also change the save format to other types such as JPG or BMP, allowing them to balance file size and quality according to project requirements.
To check the captured image, click the "Open" button on the main screen of oCam. When you click this button, Windows Explorer opens automatically and shows the most recently captured file already selected. This feature helps users review and use captured images right away. Since it takes you directly to the folder where the file is saved through Windows Explorer, file management also becomes much easier.
oCam's capture feature is simple yet powerful, making it useful in a wide range of situations from everyday tasks to professional environments. For example, software developers can use it to record bugs or share UI designs, while instructors can use it to prepare teaching materials. In addition, through the oCam settings menu, you can change the save location to a custom folder or set file naming rules when capturing for more organized file management. In this way, oCam provides high-quality screenshots with simple controls and greatly improves work efficiency.

What Are Codecs and Digital Container Formats?
When using oCam normally, you do not need an in-depth understanding of codecs and digital container formats. However, if you want to use oCam's extended features or optimize your recording settings, it is useful to understand these two terms. Below is an easy explanation of codecs and digital container formats, focused on how they relate to oCam.
* What is a digital container format?
A digital container format refers to familiar file extensions such as AVI, MP4, MOV, and FLV. It is a meta file format that defines the structure for storing video, audio, and metadata (for example, subtitles and time information) together in a single file. Simply put, you can think of a container format as the framework of a file structure that determines how video and audio data are stored.
For more information, see Wikipedia:
https://en.wikipedia.org/wiki/Container_format
For example, if a file is an AVI file, the container format is AVI, and the video and audio data inside that file are stored according to the structure defined by AVI. A container format acts like a "container" that holds the data, while the actual method used to encode the data is determined by the codec.
* What is a codec?
A codec is hardware or software that performs encoding and decoding. It includes algorithms for compressing data, decompressing it, or converting it into another format. In oCam, codecs are used to convert screen video data into a video file and to generate audio data. The generated data is then saved according to the digital container format selected by the user.
For more information about codecs, see Wikipedia:
https://en.wikipedia.org/wiki/CodecSimply put, a codec is a tool that compresses and converts video or audio data so it can be stored or played back efficiently. Common codecs used in oCam include XVID, MPEG-1, MPEG-2, MPEG-4, and H.264, while common audio codecs include MP3 and PCM.
* Codecs and container formats in oCam
In oCam, a codec is used to encode video and audio data in order to convert screen recording data into a video file. This encoded data is then saved as a file in the digital container format selected by the user, such as AVI or MP4. For example:
- If the file extension is AVI, the container format is AVI, and the video data inside may be encoded with H.264 or MPEG-4. The audio data may be saved as MP3 or PCM.
- In the case of an MP4 file, the container format is MP4, and it may similarly contain video encoded with H.264 and audio encoded with MP3.
* Summary
In oCam, the digital container format is the framework that defines the file structure, such as AVI or MP4, while the codec is the method used to compress and convert the video and audio data inside it, such as H.264 or MP3. oCam's default settings are enough for high-quality recording, but depending on your specific purpose, such as optimizing file size or improving editing compatibility, adjusting the codec and container format can make your workflow more efficient. If needed, try selecting the codec and format you want in oCam's codec settings menu.
