oCam Advanced Settings - Hotkeys

 

oCam is software that provides various hotkeys for user convenience, helping users perform screen recording and capture tasks quickly and efficiently. In the settings window that appears when you click the "Tools - Options" menu, the "Hotkeys" category on the left provides options for setting or disabling hotkeys that let you quickly run oCam's main features. These settings are useful for everyone from beginners to IT professionals who want to streamline their workflow. Below is a detailed explanation of the main settings in the "Hotkeys" category.


Overview of Hotkey Settings

The "Hotkeys" category is focused on letting you run oCam's main functions, such as Start/Stop Recording, Pause, Screen Capture, and Find Target Window, using keyboard shortcuts. Default hotkeys are already assigned for each function, but users can freely change or disable them to match their working environment or personal preference. Using hotkeys greatly improves productivity by allowing you to work quickly without using the mouse.


Recording Hotkey

The "Recording Hotkey" option lets you set the shortcut used to start or stop screen recording. The default hotkey is set to F2. Pressing this hotkey immediately starts recording or stops a recording already in progress. Users can change this setting to a more convenient key or key combination, such as Ctrl+R or Alt+F2. This feature is especially useful in situations that require quick control, such as recording gameplay or live lectures.


Pause Hotkey

The "Pause Hotkey" option lets you set the shortcut used to temporarily pause recording. The default hotkey is set to Shift+F2. This feature is useful when you want to skip certain sections or pause briefly during a recording. For example, you can use this hotkey to leave out unnecessary waiting time during a lecture or to pause recording briefly while editing a certain part of gameplay. Users can change it to a different key combination if needed.


Capture Hotkey

The "Capture Hotkey" option lets you set the shortcut used to capture the screen. The default hotkey is set to F3, and pressing this key saves the selected screen area as an image. This feature is very convenient when you want to quickly capture a moment on the screen for software guides, tutorial materials, or documentation. Users can change the hotkey to suit their work environment, for example to avoid key conflicts with another capture program they use frequently.


Find Target Window

The "Find Target Window" hotkey is the shortcut used to run the "Find Recording Target Window" feature provided when you click the "Resize" button in the oCam main window. The default hotkey is set to F4. This feature is used to automatically detect a specific window or application and set it as the recording area. For example, if you want to record only a specific program window, pressing this hotkey allows oCam to quickly recognize that window and set the recording area. You can change this hotkey to a key that better fits your workflow.


How to Change or Disable Hotkeys

Changing a Hotkey: To change a hotkey, click the input field for the function you want, then enter the new key or key combination, such as Ctrl+Alt+R. After that, click the "OK" button at the bottom right of the settings window to apply the change. Be careful not to assign duplicate hotkeys, and it is best to choose keys that do not conflict with other programs.

Disabling a Hotkey: If you do not want to use a hotkey, simply uncheck the checkbox next to that function. This disables the hotkey for that feature, and the key input will be ignored. This is useful for users who prefer to control oCam only with the mouse instead of using hotkeys.


Usage Tips

The settings in the "Hotkeys" category can greatly improve work efficiency. For example, if you want to start or stop recording quickly during a game stream, it is a good idea to set the "Recording Hotkey" to a key you use often so you can control it instantly. The "Pause Hotkey" is useful for removing unnecessary parts during long recording sessions, and the "Find Target Window" hotkey is efficient when you need to quickly select a specific application while multiple windows are open. When changing hotkeys, it is important to test them in advance to make sure they do not conflict with keys used by other software.


Also, if you use hotkeys often, it can help to write down the hotkeys for each function or keep the oCam settings window easy to open so you can check them quickly. If you often forget hotkeys, you can use the buttons in the oCam main window instead or adjust the settings to minimize hotkey use.


Today's News/Tips

Can I record only the computer system sound and save it as MP3?

Not only video recording, but audio recording is also now supported.


You can record through the following simple steps.


In the oCam main window, click the Sound tab at the top.


 


Then the mode is changed to audio recording.


In this state, when you click the Record button, system sound is recorded instead of screen recording.


Then click the Codec button as shown below to set which audio file type to save.


(Currently, MP3, WMA, FLAC, and M4A extensions are supported.)


1. MP3 (MPEG-1 Audio Layer 3)

  • Features: MP3 is the most widely used audio compression format, developed in the 1990s.
  • Compression method: It uses lossy compression, which greatly reduces file size.
  • Sound quality: Some audio data is lost during compression, so quality may drop compared to the original. However, at 192 kbps or higher, most users may not notice a clear difference.
  • File size: About 2.4 MB per minute at 320 kbps, which is relatively small.
  • Compatibility: It is supported on almost all devices and software, making it suitable for streaming, downloading, and playback.
  • Use case: Commonly used for portable music players, online streaming, and everyday music listening.

2. WMA (Windows Media Audio)

  • Features: An audio format developed by Microsoft, designed as an alternative to MP3.
  • Compression method: Supports both lossy and lossless compression modes.
  • Sound quality: Claimed to provide better quality than MP3 at the same bitrate, though the actual difference is often minimal. Lossless WMA preserves original audio quality.
  • File size: Similar to MP3 in lossy mode; in lossless mode, files are much larger (about 10~20 MB per minute).
  • Compatibility: Strong support in Windows environments, though compatibility may be weaker on other platforms such as macOS or some Android devices.
  • Use case: Mainly used in Windows-based software and Microsoft products such as Xbox; DRM support makes it suitable for protected content distribution.

3. FLAC (Free Lossless Audio Codec)

  • Features: A popular lossless audio format among audiophiles.
  • Compression method: Uses lossless compression, preserving 100% of the original audio data.
  • Sound quality: Provides original-quality audio with no loss, suitable for high-resolution playback.
  • File size: Much larger than MP3, but about 50~70% smaller than the original WAV file (roughly 20~30 MB per minute).
  • Compatibility: Supported by most advanced audio players and software, but may be difficult on some low-spec or older devices.
  • Use case: Suitable for high-quality music listening, audio archiving, and studio work where preserving quality is important.

4. M4A (MPEG-4 Audio)

  • Features: An MPEG-4 based audio format mainly used by Apple, including AAC (Advanced Audio Coding) and ALAC (Apple Lossless Audio Codec).
  • Compression method: Supports lossy AAC and lossless ALAC.
  • Sound quality: AAC is more efficient than MP3 and often provides better quality at the same bitrate. ALAC preserves original quality as lossless.
  • File size: AAC is similar to or slightly smaller than MP3 (about 2 MB per minute), while ALAC is similar in size to FLAC (about 20~30 MB per minute).
  • Compatibility: Strongly supported on Apple devices (iTunes, iPhone, iPad) and macOS; some Android devices or other platforms may require additional codecs.
  • Use case: Mainly used in iTunes, Apple Music streaming, and podcasts, with AAC suitable for streaming and efficient storage.

Additional tips

  • If you prioritize quality: choose FLAC or M4A (ALAC).
  • If you prioritize file size and compatibility: choose MP3 or M4A (AAC).
  • In Windows environments: WMA is also a good option, but MP3 may be more universally compatible.
  • For Apple device users: M4A is most suitable, and AAC is especially good for streaming and saving storage.
