The parts that are changed are as follows.

Preset-Ultrafast (Set to improve encoding speed and can increase file size, but other options will cause more racks.)

Profile-High 4: 4: 4 (Changes to High 444 for lossless encoding as the default profile may lose video quality.)

Keep input colorspace-Maintains the color space of the internally received buffer. (Other options may cause encoding to fail.)

Rate control-Single pass-lossless-Change for lossless encoding.

Press the OK button to apply the setting.


Since the settings are applied to x264vfw64 for 64-bit when recording 64-bit games, run x264vfw-Configure x264vfw64 from the Start menu and set them as shown above.

If you record with the above settings, you will be recording losslessly, where the important part is to change the settings of the video player to play lossless video losslessly.

The following shows how to check the lossless video based on the next pot player.

After launching the next pot player, click Preferences (F5).

 

 
In the environment setting window

Click Image-Colorspace / Properties on the left, and then select Convert directly if possible-Change to default output colorspace in the Colorspace group box on the right. (If this setting is not made, the color of the screen will be lost when playing the video even if the recording is lossless.)


Press OK and play the video recorded without loss.

At this time, if you press Ctrl + F1 on the next pot player, the video codec output format must be output in RGB (32 Bits) as shown below.


In addition, the properties below should be identical in the Playback Information-File Information tab as shown in the following figure.

[HOWTO]Resizing the recording area

In the main screen of oCam, there is a button called Resize.

A popup menu will appear as shown below.

 


The yellow highlighted area in the pop-up menu indicates the resolution of the recording area, and clicking on the menu item will change the size of the recording area to the selected resolution.

 


The maximum resolution supported is 4k by default, and up to 8k for MPEG-4 codec only.

If you click the full screen menu item, the recording area is set to the entire screen. If you start recording in this state, the entire screen is recorded.

The Find Recording Window menu item displays the window indicated by the mouse pointer as a red rectangle box when clicked. If clicked, the area of ​​the window indicated by the mouse pointer is designated as the recording area.

Find Record Destination window is useful when you want to record or capture only a specific window.

Custom size menu item can be clicked and user can input the size of recording area by number as follows.
