Setting the Codec - Selecting an External Video Codec (VFW)
oCam is a simple and intuitive screen recording program that offers a user-friendly interface and a wide range of features, making it a useful tool for everyone from beginners to IT professionals. In particular, oCam supports a variety of codecs so users can record with the quality and settings they want. Among them, using external VFW (Video for Windows) codecs such as x264vfw or Xvid allows for a more flexible recording environment. Below is a detailed explanation of how to set up and use external codecs in oCam.
How to Set Up an External Codec
To use an external codec in oCam, you first need to go to the program's codec settings menu. On the main screen of oCam, click the Codec menu located at the top or in the settings menu, and a pop-up window related to codec selection will appear. This pop-up window provides options for choosing built-in codecs and external codecs, and here you should select the external codec option. Please note that external codecs support only the AVI container format. This is because the AVI format has excellent compatibility with VFW-based codecs.
When you select the external codec option in the pop-up window, a new settings window will open. This window includes a checkbox labeled 'Use External Codec,' and you need to enable this checkbox to configure an external codec. After checking the box, click the combo box at the bottom of the window to display a list of VFW-based external codecs installed on your computer. For example, if codecs such as x264vfw or Xvid are installed, you can choose the one you want from this list. After selecting a codec, click the OK button to save the setting.
Recording with an External Codec
Once the codec setup is complete, the external codec you selected will be applied automatically when you start recording in oCam. The x264vfw codec provides a high compression ratio and excellent image quality, making it suitable for high-resolution video recording, while Xvid is useful in a variety of environments thanks to its relatively small file size and stable performance. You can choose the appropriate codec based on the type of content you want to record. For example, you can choose x264vfw for high-quality gameplay recording, or Xvid if you want to minimize file size.
The recorded video will be saved in AVI format, and the image quality and file size will vary depending on the characteristics of the selected codec. Therefore, when using an external codec, it is a good idea to check and optimize the codec settings in advance, such as bitrate and frame rate. Some codecs provide a separate settings window where you can adjust detailed options, so using that when needed can give you more satisfying results.
Disabling the External Codec
If you no longer want to use an external codec, you can easily revert the setting. Go back to the Codec menu in oCam, select the external codec option, and then clear the 'Use External Codec' checkbox. Once the checkbox is cleared, oCam will automatically switch back to the built-in codec that was previously in use. Built-in codecs are generally easier to configure and are suitable for users who do not want more complex settings. Even after switching back to a built-in codec, recording quality remains stable, and you can still get optimized results based on oCam's default settings.
Advantages and Precautions When Using External Codecs
The biggest advantage of using external codecs is that you can fine-tune image quality and file size exactly the way you want. In particular, codecs such as x264vfw can save high-quality video in relatively small file sizes, which is a major benefit for users working with high-spec content. On the other hand, the relevant codec must be installed on your computer, and some codecs can consume a large amount of system resources, so your hardware specifications should be taken into account. Also, due to the nature of the AVI container, compatibility may be more limited than with other formats such as MP4, so it is worth keeping this in mind if you plan to edit or share the recorded video afterward.

oCam Advanced Settings - Animated GIF
oCam is versatile software that not only supports screen recording and capture but also provides a GIF animation feature, allowing users to save short video clips as lightweight and easy-to-share GIF files. In the settings window that appears when you click the "Tools - Options" menu, the "Animated GIF" category on the left provides options for adjusting settings related to GIF creation. This tab applies when you click the "Codec" button in the main oCam window and choose the "Animated GIF (.GIF)" codec, and it is useful for optimizing the quality and format of GIF files. Below is a detailed explanation of the main settings in the "Animated GIF" category.
Overview of GIF Settings
The settings in the "Animated GIF" category are options that apply when recording in GIF format in oCam, and they are only enabled when the codec in the main window is set to "Animated GIF (.GIF)." GIF is a format suitable for sharing short animated clips on social media, websites, or messaging apps because the file size is relatively small and it can be played easily on most platforms. Through these settings, users can adjust the visual elements and quality of the GIF as needed.
Include Mouse Cursor
The "Include Mouse Cursor" option determines whether the mouse cursor will be included when recording a GIF animation. By default, this option is checked, so the mouse cursor is included in the GIF. This is useful when creating GIFs for tutorials, software demos, or situations where you want to emphasize mouse movement. For example, if you want to show the process of clicking a specific button in a GIF, including the cursor is effective. On the other hand, if the cursor is unnecessary or you want a cleaner GIF, you can disable this option to record without the cursor.
GIF Settings - FPS
The "GIF Settings - FPS" option sets the number of frames per second for the GIF animation. FPS directly affects both the smoothness of the GIF and the file size. Choosing a higher FPS, such as 30 FPS, makes the GIF play more smoothly, but the file size may become larger. On the other hand, choosing a lower FPS, such as 10 to 15 FPS, reduces the file size but may make the animation look less smooth. Users should choose an appropriate FPS based on the requirements of the sharing platform or file size limits. For example, for a short GIF uploaded to social media, 15 to 20 FPS is usually enough to get a natural-looking result.
Resize
The "Resize" option sets the output resolution of the GIF animation and works in the same way as the settings under the "Recording - Resize" tab. This setting applies only to the GIF codec and allows users to adjust the size of the GIF to the resolution they want. The supported resolution presets are as follows:
4320p UHD 8K (7680x4320), 2160p UHD 4K (3840x2160), 1440p QHD (2560x1440), 1080p FHD (1920x1080), 720p HD (1280x720), 480p (854x480), 360p (640x360), 240p (426x240), 144p (256x144), 120p (160x120), 96p (128x96)
Half Size: Reduces both the width and height of the recording area by half.
Specify Width Only and Keep Height Fixed: Sets the width while adjusting the height to match the original aspect ratio.
Specify Height Only and Keep Width Fixed: Sets the height while adjusting the width to match the original aspect ratio.
Custom: Lets the user directly enter the width and height to adjust the size exactly as desired.
Since GIF files are generally easier to share when the file size is small, it is common to choose a lower resolution such as 720p or below, or use the "Half Size" option. However, if you set a GIF to a very high resolution such as 8K, the file size can increase dramatically, so it is important to choose the settings while considering the upload limits and intended use of the platform.
Usage Tips
The settings in the "Animated GIF" category play a key role in creating GIF animations quickly and effectively. For example, if you want to make a short clip for social media, you can set the FPS to 15 to 20 and the resolution to 480p or 720p to optimize file size. Including the mouse cursor is useful when you want to highlight user actions, but if you prefer a cleaner visual style, it is better to leave the cursor out. Also, after creating a GIF, you can check the file size and, if necessary, re-record it with a lower FPS or resolution to match the limitations of the target platform.
GIF uses lossless compression, so it can maintain clear images without quality loss, but the number of colors may be limited, so it is a good idea to preview the result when recording screens with complex colors. Setting the save path in advance in oCam can also help you quickly find and use the GIF files you create.
