If you want to use various video codecs with oCam, you can install external codecs to adjust recording quality and file formats the way you want. Below is information about the external codecs supported by oCam and how to install them. Installing external codecs allows you to use oCam more flexibly.


After installing an external codec, you must restart oCam. Once restarted, the installed codec will automatically appear under the 'External Codec' option in the oCam settings menu, where you can select it for recording. External codecs can be downloaded from the following link:

The following are descriptions of the main external codecs supported by oCam:  


Xvid Video Codec  

The Xvid codec is a video codec that implements the MPEG-4 Simple Profile and Advanced Simple Profile standards. This codec offers efficient compression and high compatibility, making it suitable for creating videos that can be played on a wide range of devices and software. With Xvid, you can keep file sizes reasonable while minimizing quality loss during recording.


x264vfw Codec  

x264vfw is a VfW (Video for Windows) codec that includes the widely known x264 encoder and ffh264 decoder. Based on the H.264 format, this codec can save high-quality video in a smaller file size. x264vfw is especially suitable for users who want sharp image quality and efficient compression, and it also offers excellent compatibility with various video editing software.


VP8 Codec  

The VP8 codec can encode video at quality comparable to or better than H.264 video encoders. VP8 is a core component of the WebM format and is well suited for web-based video streaming or high-quality video storage. With this codec, you can reduce file size while maintaining clear image quality for efficient recording.


Lagarith Codec  

Lagarith is a lossless video codec designed for video editing and archiving. As a lossless codec, it preserves the original video quality exactly, but the file size can be relatively large. Therefore, it is suitable for users who want to edit high-quality video or store it for the long term.


By installing and using external codecs in oCam, users can choose the best codec for their recording purpose and environment. For example, if you want to reduce file size, you can choose x264vfw or VP8, and if you want to create editing footage without quality loss, you can choose Lagarith. Download the codec you need from the link above, restart oCam, and apply the codec you want.

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.
