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 - Sound
oCam is user-friendly software that not only supports screen recording but also allows you to fine-tune sound recording settings, helping you achieve optimized recording for a wide range of audio input environments. In the settings window that appears when you click the "Tools - Options" menu, selecting the "Sound" category on the left lets you check and adjust microphone-related settings. This tab is especially useful for users who need to solve microphone input issues or apply specific audio settings. Below is a detailed explanation of the settings available under the "Sound" category.
Current Microphone Settings
The "Sound" category provides options related to the current microphone settings, and by default, these settings are configured appropriately for most users, so they can usually be used reliably without any changes. In a typical recording environment, both system sound and microphone audio are recorded properly, and the default settings are generally enough to capture high-quality audio. For example, when using microphone input for lecture videos or game streaming, the default settings are sufficient for most needs.
Resolving Microphone Audio Issues
However, in certain situations, especially when using a USB audio interface or advanced audio equipment, you may encounter an issue where microphone sound is played through only one speaker, either the left or the right. This usually happens when the audio input channel settings are not configured correctly. In the "Sound" category of oCam, simple setting adjustments are provided to resolve this issue.
If sound is coming from the left speaker only: Change the microphone input source to "Input 1 (Left Channel)" to fix the problem. This setting correctly adjusts the microphone audio signal when it is focused only on the left channel, allowing balanced output through both speakers.
If sound is coming from the right speaker only: Change the microphone input source to "Input 2 (Right Channel)." This setting adjusts the audio signal coming into the right channel so that it is evenly distributed through both speakers.
These setting changes are especially useful in environments that use USB audio interfaces or stereo input, and they are an essential feature for users who want to optimize audio quality.
Usage Tips
The settings in the "Sound" category are simple, but they are very effective for resolving issues in certain audio environments. For example, streamers or content creators using a USB microphone or audio interface can quickly fix audio channel issues through these settings. After changing the settings, it is a good idea to run a short test recording to make sure the microphone audio is being recorded evenly on both channels. It is also important to adjust the microphone input level properly so that the sound is not too loud or too quiet.
If you are in a normal environment without a USB audio interface, you can usually get stable recording results just by keeping the default settings. However, if you are using advanced audio equipment, adjusting these settings to balance the audio output can be very helpful in improving the overall quality of the video.
