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.

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.
