The System Becomes Sluggish During Recording

Using oCam at work or school? A license is required, and it removes all ads, including this window. See the paid version →

When recording with oCam, if the mouse moves slowly or the entire system feels sluggish, you need to adjust the settings to resolve the issue. Below is a detailed explanation of how to reduce the problem and lower the system load.


1. Click the 'Settings' button in the oCam main window.

2. When the Settings window opens, go to the 'Encoding' tab in the menu on the left.

3. In the 'Encoding' tab, check the 'Frames Per Second (FPS)' setting. The default value is likely set to 30.

4. Gradually lower the FPS value while testing system performance. For example, start at 30 and reduce it step by step to 25, 20, 15, and 10.

5. At each step, start recording and check whether the mouse movement or system sluggishness improves.

6. After finding the optimal FPS value for your PC specifications, click the 'OK' button to save the settings.


Lowering the FPS may reduce video smoothness, but it can also reduce system resource usage and improve slowdown during recording. It is important to experimentally find the FPS value that best suits your PC specifications (CPU, GPU, RAM, etc.). After changing the setting, make a test recording to find the best balance.

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/Codec


Simply 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.
