How to Move the Recording Area While Recording
Using oCam at work or school? A license is required, and it removes all ads, including this window. See the paid version →
The ability to move the recording area while recording with oCam is very useful when you want to flexibly capture a specific part of the screen in real time. Below is a detailed explanation of how to move the recording area during recording.
To change the recording area while recording is in progress, you can use the border of the recording area. Specifically, even after recording has started in oCam, you can click and drag the border of the recording area window with the mouse to move the recording area to the desired position in real time. This feature can be used simply with mouse control and is intuitive to use without any separate shortcut keys or complicated settings.
For example, when recording gameplay, if a specific part of the screen moves or changes, such as a character's position or a certain UI element, you can drag the border to adjust the recording area in real time and capture the scene you want without missing it. This method is especially useful when recording dynamic content, helping the user respond quickly and continue tracking the necessary screen area.
When moving the recording area, you need to click and drag the border accurately. If you move it too quickly, it may shift to an unintended position, so it is best to control it smoothly and precisely. By using this feature, you can perform more flexible and efficient recording with oCam.

How to Use the x264vfw External Codec
oCam supports external codecs (VFW), and here we will look at how to use the x264 codec.
You can download the x264 codec from the site below.
https://sourceforge.net/projects/x264vfw/
Go to the site and click the Download button.
The download will start automatically.
On the installation screens, just keep clicking Next.
Accept the license agreement.
Specify the installation path.
The installation is complete.
Click Finish.
After installing the codec, you must restart oCam before it will appear in the external codec list.
After restarting oCam, click the Codec button in the oCam main window, then click the External Codec menu.
Select the Use External Codec checkbox.
From the list, select x264vfw - H264/MPEG-4 AVC codec.
Then click the Settings button to view the detailed codec settings.
The codec settings window will appear as shown below. Since we need to record the screen in real time rather than perform normal video encoding, select Ultrafast in Preset and check the Zero Latency checkbox so that encoding is performed as quickly as possible, then click the OK button.
( This setting method is useful for real-time recording, and you can adjust it as needed depending on your situation. )
After configuring it this way, your recording will use the x264 codec.
* For game recording, if the game you want to record is 64-bit, you must also install the 64-bit version when installing x264vfw ( by default, it is installed automatically unless you change the installation options ). Then run x264vfw - Configure x264vfw64 from the Start menu and configure it the same way as described above.
* The x264vfw settings Keep/Accept only YUV 4:2:0, Keep/Accept only YUV 4:2:2, and Keep/Accept only YUV 4:4:4 are not supported, and recording will fail if you use those settings.
