[Tips]How to record sound when using the USB audio interface

Rather than playing sound with the built-in sound card, you can record sound played by the audio device when you purchase an additional USB audio device. For example, if your additional USB audio device is a Scarlett 2i2 USB,

 

1) Click the Sounds item in Control Panel.

 

2) Click to bring up the window below and you will see the newly connected USB audio device in the Playback tab.

Select the USB audio device and click "Set as Default".

You can see it is set as default device.

 

Now, the sound played by the system is played by the device, and the sound from the device is recorded when recording from oCam.

[Tips]Lossless recording-using x264vfw

* Before you begin, you need to install the x264 codec and you can find the instructions in the following link.

(http://cafe.naver.com/ohsoft/618)

Click on CODEC menu of OHCAM and click on the external codec menu item.

Check Use External Codec, select the x264vfw codec and click the Settings button.

 
Based on the x264vfw default setting, change the yellow box in the figure below as shown.


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.

Format profile: High 4: 4: 4 Predictive @ L3
Color space: RGB
Color range: Full
Matrix coefficients: RGB
