How to Record Audio Only with oCam
Using oCam at work or school? A license is required, and it removes all ads, including this window. See the paid version →
On the main screen of oCam, click the Audio Recording tab to open a simple, user-friendly menu. This menu provides various recording options in oCam, allowing users to adjust the settings as needed. One of oCam's strengths is its intuitive interface, which makes it easy to use for everyone from beginners to IT professionals.
You can use this feature whenever you want to record only audio, such as for creating audio content, recording podcasts, or capturing background music.
Click the Sound button to choose the audio source, such as system sound or microphone input settings, and then click the Record button on the screen to start recording. This feature is very useful for tasks where you need to focus only on audio. For example, it is efficient when you want to extract lecture audio separately, record an interview, or make a simple voice recording. Thanks to oCam's simple controls, these settings can be changed in just a few clicks, making the user experience even more convenient.
By default, audio files are saved in MP3 format. MP3 is one of the most widely used formats for audio recording because it offers small file sizes and excellent compatibility with most devices and software. It provides a good balance between sound quality and file size, making it suitable for general use. However, for users with more specific needs, oCam also provides an option to select audio codecs other than MP3 through the Codec button. If you choose AAC format, you can maintain high sound quality with efficient compression, giving you more flexibility depending on your project.
These settings clearly show how simple yet powerful oCam is. oCam is more than just a screen recording tool. It is versatile software that also supports professional audio recording tasks. Users can further adjust details such as the file save location, audio quality, and input source in the oCam settings menu. For example, you can adjust the volume levels of the microphone and system sound separately, or specify a save folder to optimize your workflow. Thanks to this flexibility and convenience, oCam is widely used in many different environments, from individual users to IT professionals. If you want high-quality audio recordings, it is recommended to adjust the codec and detailed settings to match your working environment for the best results.

How to Record Losslessly Using x264vfw
Before getting started, you must install the x264 codec in advance. If you do not know how to install it, please refer to the Help section.
Click the Codec menu in oCam, then click the External Codec menu item.
Select Use External Codec, choose the x264vfw codec, and then click the Settings button.
Using the default x264vfw settings as a base, change the parts highlighted in the yellow box in the image below as shown.
The following settings need to be changed.
Preset - Ultrafast ( Set this to improve encoding speed. The file size may become larger, but if you choose other options, significant lag may occur. )
Profile - High 4:4:4 ( The default profile may cause quality loss, so change it to High 4:4:4 for lossless encoding. )
Keep input colorspace - Keeps the color space of the internally received input buffer. ( If you use other options, encoding may fail. )
Rate control - Single pass - lossless - Change this for lossless encoding.
Click the OK button to apply the settings.
When recording 64-bit games, the settings are applied to x264vfw64 for 64-bit, so run x264vfw - Configure x264vfw64 from the Start menu and configure it in the same way as shown above.
If you record with the above settings, the video will be recorded losslessly. One important point is that if you want to play back the lossless video without quality loss, you must change the settings in your video player.
Below is how to check a lossless video using PotPlayer.
Run PotPlayer, then click Preferences ( F5 ).
In the Preferences window,
click Video - Color Space/Attributes on the left, then in the Color Space group box on the right, select Convert manually if possible - Default output color space. ( If you do not configure this, even if the recording is lossless, the screen colors may still be altered during playback. )
Click OK, then play the video recorded losslessly.
At this point, press Ctrl + F1 in PotPlayer. As shown below, the output format of the video codec must be displayed as RGB(32 Bits).
Also, in the playback information under the File Information tab, the following properties must match as shown below.
Format profile : High 4:4:4 Predictive@L3
Color space : RGB
Color range : Full
Matrix coefficients : RGB
