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 - Choosing a Video Codec

oCam is an intuitive and lightweight free software tool that allows users to record or capture their screen, making it suitable for a wide range of users from beginners to IT professionals.

It is also a screen recording and capture program with a simple interface and powerful features, making it useful for gameplay recording, online lectures, tutorial creation, and simple screenshot capture. Thanks to the intuitive buttons on the main screen, even beginners can use it easily, while advanced users can create an optimized recording environment through detailed settings.



 

Codec Settings and Video Containers

When you click the "Codec" button on the main screen of oCam, a settings window appears where you can choose the video container and video codec. This settings window is designed to let users freely adjust the recording file format and quality. The video containers supported by oCam include the following formats:



MP4: The most widely used video format, offering excellent compatibility and reasonable file sizes.

MKV: A multimedia container that supports high-quality video and various codecs. (A container that can continue playback even if recording is interrupted partway through.)

M4V: A format optimized for compatibility with Apple devices.

MOV: A QuickTime-related format suitable for users who prefer high-quality video.

WMV: A Microsoft video format mainly used in Windows environments.

FLV: A Flash-based video format often used for web streaming.

AVI: An older format that is still compatible with a wide range of software.

TS: A streaming format suitable for high-definition broadcast recording.

VOB: A format mainly used for DVD video.

By supporting such a wide range of containers, users can choose the file format that best fits their platform or purpose.


Supported Video Codecs

oCam provides a variety of video codecs to help optimize recording quality and performance. The supported video codecs are as follows:


NVIDIA NVENC H.264: A high-efficiency codec that uses hardware acceleration and delivers excellent performance on systems equipped with NVIDIA graphics cards.

Open H.264: An open-source H.264 codec that provides high compression efficiency and good quality.

MPEG-4: A widely used codec with excellent compatibility across many devices.

Microsoft MPEG-4 Part 2 and Part 3: Codecs optimized for Microsoft environments.

Windows Media Video 8 (WMV8): Provides efficient compression on Windows-based systems.

MPEG-2: A codec suitable for DVD-quality video.

MPEG-1: An older format that is still useful on lower-spec systems.

FLV: A codec specialized for Flash video.

In particular, the NVIDIA NVENC H.264 codec uses the hardware encoder built into NVIDIA graphics cards to minimize CPU load, allowing smooth recording with almost no lag even during demanding tasks such as gameplay recording. However, this codec is only supported on certain NVIDIA graphics cards or higher, so recording may fail if your graphics card does not support it. For that reason, it is important to check your system specifications before selecting this codec.


Audio Codecs and Additional Features

oCam supports not only video recording but also audio recording, allowing you to capture sound together with screen recordings. The supported audio codecs are as follows:


AAC: Offers high sound quality and efficient compression, and is compatible with most modern video containers.

MP3: The most widely used audio format, offering a good balance between file size and sound quality.

MP2: An audio codec often used for broadcasting and DVDs.

WMA: A Microsoft audio format optimized for Windows environments.

FLAC: A lossless audio codec that provides high-quality sound close to the original source.

With these audio codec options, users can adjust the sound quality of recorded videos as needed. For example, you can use AAC for clear lecture audio or MP3 for gameplay recordings to maintain a good balance between quality and file size.


GIF Support

oCam also supports GIF format, which is useful for users who want to create short and lightweight animated files. When you select GIF mode, an animated GIF file is created instead of a video file, making it suitable for sharing on social media or creating simple tutorials. Since GIF files can be large and are not ideal for high-resolution video, it is best to choose this format according to your needs.


Things to Keep in Mind

There are a few things to keep in mind when using oCam. In particular, if you use the NVIDIA NVENC H.264 codec, you should always check your hardware specifications first. If you select this codec on an unsupported graphics card, recording may fail or errors may occur. It is also important to make sure you have enough storage space and system resources when recording in high resolution or for long periods.


Conclusion

oCam is software designed to make screen recording and capture easy for anyone through a simple interface and powerful features. It supports a wide range of video containers and codecs, and hardware-accelerated recording with the NVIDIA NVENC H.264 codec in particular delivers excellent performance even for demanding tasks. With support for audio codecs and GIF creation as well, oCam is a versatile tool that can be useful in many different environments, from individual users to professionals. If you carefully choose the codec and settings that match your system specifications and intended use before starting a recording, you will be able to get the best results.
