oCam is a multifunctional program that not only supports screen recording but also provides a screen capture feature, allowing users to save specific moments on the screen as images easily. In the settings window that appears when you click the "Tools - Options" menu, the "Capture" category on the left provides options for adjusting settings related to screen capture. This tab is designed so users can customize the details of the capture feature, and it can be used intuitively by everyone from beginners to IT professionals. Below is a detailed explanation of the main settings in the "Capture" category.
Overview of the Capture Feature
The settings in the "Capture" category are the options that apply when you click the "Capture" button in the main oCam window or press the default hotkey (F3). Through these settings, users can choose the format of the captured image and decide whether to include additional elements such as the mouse cursor. The capture feature is very useful when creating tutorials, preparing software documentation, or saving a specific moment on the screen.
Include Mouse Cursor
The "Include Mouse Cursor" option determines whether the mouse cursor will be included in the captured image. By default, this option is unchecked, so the mouse cursor is not included in captured images. This is suitable when you want a clean image. However, if you want to highlight the cursor position for lecture materials or software usage guides, you can check this option to include the cursor in the image. For example, when capturing the process of clicking a specific button, including the cursor can make the material visually clearer.
Image File Format for Capture
The "Image File Format for Capture" setting lets you choose the file format used to save captured images. oCam supports several image formats, and by default it is set to PNG. PNG is the most recommended format because it provides lossless compression, allowing you to save clear images without any loss in quality. Other supported formats may include JPEG and BMP. JPEG is useful when you want to reduce file size, but it may cause some loss of image quality. Users can choose the most appropriate format by considering storage space, image quality requirements, or compatibility with a particular platform.
Usage Tips
The settings in the "Capture" category are simple, but they play an important role in improving how captured images can be used. For example, when creating tutorials, enabling the "Include Mouse Cursor" option can clearly show where the user is clicking or interacting. Using PNG format by default helps maintain high image quality, making it suitable for professional documentation. On the other hand, if minimizing file size is important, you can choose JPEG format to save storage space. If you often use the capture hotkey (F3), changing it to a different key or becoming familiar with it can also help improve your workflow.
In addition, if you want to review and edit captured images immediately after saving them, it is a good idea to set the save location in advance in oCam. This makes it easier to find and use captured images quickly. If you are capturing the UI of specific software or a game screen, be sure to define the capture area accurately so that unnecessary parts are not included.
Before getting started, you must install the x264 codec in advance. If you do not know how to install it, please refer to the Help section.
Click the Codec menu in oCam, then click the External Codec menu item.
Select Use External Codec, choose the x264vfw codec, and then click the Settings button.
Using the default x264vfw settings as a base, change the parts highlighted in the yellow box in the image below as shown.

The following settings need to be changed.
Preset - Ultrafast ( Set this to improve encoding speed. The file size may become larger, but if you choose other options, significant lag may occur. )
Profile - High 4:4:4 ( The default profile may cause quality loss, so change it to High 4:4:4 for lossless encoding. )
Keep input colorspace - Keeps the color space of the internally received input buffer. ( If you use other options, encoding may fail. )
Rate control - Single pass - lossless - Change this for lossless encoding.
Click the OK button to apply the settings.
When recording 64-bit games, the settings are applied to x264vfw64 for 64-bit, so run x264vfw - Configure x264vfw64 from the Start menu and configure it in the same way as shown above.
If you record with the above settings, the video will be recorded losslessly. One important point is that if you want to play back the lossless video without quality loss, you must change the settings in your video player.
Below is how to check a lossless video using PotPlayer.
Run PotPlayer, then click Preferences ( F5 ).
In the Preferences window,
click Video - Color Space/Attributes on the left, then in the Color Space group box on the right, select Convert manually if possible - Default output color space. ( If you do not configure this, even if the recording is lossless, the screen colors may still be altered during playback. )
Click OK, then play the video recorded losslessly.
At this point, press Ctrl + F1 in PotPlayer. As shown below, the output format of the video codec must be displayed as RGB(32 Bits).
Also, in the playback information under the File Information tab, the following properties must match as shown below.
Format profile : High 4:4:4 Predictive@L3
Color space : RGB
Color range : Full
Matrix coefficients : RGB
