How to Set the Frame Rate Mode - VFR (Variable Frame Rate) or CFR (Constant Frame Rate)

oCam is a user-friendly screen recording program that offers powerful features for a wide range of uses. It is widely used in situations that require screen recording, especially for gameplay recording, lecture creation, and tutorial video production. By default, oCam is set to use Variable Frame Rate (VFR), which is designed to operate flexibly depending on system performance and the recording environment.

Variable Frame Rate mode is the default setting in oCam. Even if the user sets the frame rate to 60 FPS in the recording settings, the actual recorded result may vary depending on system performance or the condition of the content being recorded. For example, when recording a game, if the game itself cannot maintain 60 FPS and runs at an average of 30 FPS, oCam will reflect that and record at 30 FPS. This design helps use system resources efficiently and ensures stable recording without interruptions.

In addition, Variable Frame Rate works effectively even when the system specifications do not fully meet the recording requirements. If lag occurs during gameplay, or if the system cannot maintain 60 FPS while attempting high-spec screen recording, oCam will automatically adjust the frame rate to match system performance and continue recording. This allows video to be saved at the best possible quality without overloading the system.

However, videos recorded with Variable Frame Rate can cause inconvenience in certain situations. In particular, problems may occur when using professional video editing software such as Adobe Premiere Pro. Because videos recorded with Variable Frame Rate do not have consistent frame intervals, audio and video may go out of sync during editing. To prevent this, it is recommended to change the setting in oCam to Constant Frame Rate (CFR) before recording.

When set to Constant Frame Rate, oCam tries to maintain the frame rate specified by the user, such as 60 FPS, and records frames at consistent intervals regardless of system performance. This makes editing more stable in video editing software and is especially helpful for keeping audio and video perfectly synchronized. Therefore, if you plan to edit the video afterward, recording with Constant Frame Rate is strongly recommended.

Changing the frame rate mode in oCam is very simple. After launching oCam, select 'Options' from the menu and go to the 'Recording' tab. Then click the 'General' tab, where you can find the setting to change the frame rate mode to either Variable Frame Rate (VFR) or Constant Frame Rate (CFR). With this setting, users can freely adjust the recording method to suit their working environment and purpose.

 

With its intuitive interface and simple controls, oCam is software that can be used easily by anyone from beginners to professionals. By selecting Variable Frame Rate or Constant Frame Rate according to the situation, you can smoothly handle a variety of tasks, from game recording to video editing.

Tips for Precisely Adjusting the Recording Area Window

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.
