Tips for precisely adjusting the recording area window


When setting the recording area in oCam, being able to precisely adjust the position and size of the window is very useful. oCam provides intuitive shortcut keys for this, allowing users to fine-tune the recording area exactly as needed. Below are some tips for precisely adjusting the recording area window and how to use the shortcut keys.


In oCam, you can drag the window used to set the recording area with the mouse to move or resize it, but using shortcut keys allows for much more precise adjustment. Shortcut keys are especially useful when you need to set an exact position or size.


Adjusting the recording area position  

- Arrow keys: Press the arrow keys (up, down, left, right) to move the recording area window precisely one pixel at a time. This is useful when fine adjustment is needed.  

- Ctrl + Arrow keys: If you want to move it by a larger amount, use the arrow keys while holding down the Ctrl key. This combination moves the window more quickly, making it easier to adjust the position efficiently.


Adjusting the recording area size  

- Shift + Arrow keys: Hold down the Shift key and use the arrow keys to resize the recording area window. The up and down arrow keys adjust the height of the window, and the left and right arrow keys adjust the width. This also allows precise adjustment one pixel at a time.  

- Shift + Ctrl + Arrow keys: If you want to resize the window by a larger amount, use the arrow keys while holding down both the Shift and Ctrl keys. This combination changes the window size more quickly in larger increments, which is useful when major resizing is needed.


These shortcut keys help you adjust oCam's recording area settings very precisely and carefully. For example, if you want to record only a specific game window or a certain part of the screen, you can first set the approximate area with the mouse and then use the shortcut keys to fine-tune it pixel by pixel for the exact result you want.


In this way, oCam provides user-friendly shortcut keys that support precise adjustment of the recording area. Make active use of these shortcut keys to set the recording area more accurately and efficiently.

The "The endpoint device is already in use." Error Appears When Recording Starts

When recording with oCam, you may sometimes encounter problems with sound recording. In particular, when a DAW (Digital Audio Workstation, for example FL Studio) program using Asio4all is running, it may take exclusive control of the system audio, making sound playback or recording unavailable in other programs. As a result, normal sound recording in oCam may become difficult. Below is a detailed explanation of how to solve this problem and record smoothly with oCam.


Asio4all is a driver used for low-latency audio processing and is mainly used in DAW programs. However, when Asio4all is enabled, it takes exclusive control of the system audio, so other programs such as oCam may not be able to capture system sound. To solve this problem, you need to change the audio output device in the DAW program to something other than Asio4all.


The following is how to change the settings:  

1. Run the DAW program (for example, FL Studio).  

2. In the case of FL Studio, click 'Options' in the top menu, then go to 'Audio Settings'.  

3. In the 'Audio Settings' window, check the audio output device and change it from Asio4all to 'Primary Sound Driver' or 'DirectSound'.  

4. After saving the settings, play audio in the DAW and then try recording with oCam. The system sound should then be recorded normally.


If you must use Asio4all because of latency issues with a MIDI keyboard, it is best to switch the settings flexibly depending on your working environment. For example:  

- When producing music or doing MIDI work in the DAW, use Asio4all to maintain a low-latency environment.  

- After finishing your work and when you want to record with oCam, change the playback device in the DAW audio settings to 'DirectSound' or 'Primary Sound Driver' to disable Asio4all.  

- After changing the setting, restart the DAW, or reboot the computer if necessary, then confirm that the setting has been applied properly before starting recording with oCam.


Using this method, you can resolve the audio exclusivity issue caused by Asio4all and record system sound smoothly in oCam. If you are working in a DAW and recording at the same time, try switching the audio output device according to the situation to maintain the best environment.
