[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]Using the x264vfw External Codec

Ocam supports external codec (VFW) and how to use the x264 codec.

The x264 codec can be downloaded from the following site.
http://sourceforge.net/projects/x264vfw/

Go to the site and click the download button.


The download starts automatically.


The installation screen is as follows only.


Agree to the terms.

 
Specify the installation path.

 
The installation is complete.

 
Click Done.

 
After installing the codec, you must re-run Ocam to see it in the external codec list.

After re-launching Ocam, click the codec button in the ocam main window and click the external codec menu.

 



Check the box to Use an external codec.

 


Select x264vfw-H264 / MPEG-4 AVC codec from the list.

 

Click on the Settings button to see the detailed settings in the codec.

 
The codec setting window will appear as shown below. Currently, we need to record the screen in real time rather than the normal video encoding, so select Ultrafast in Preset, check the Zero Latency checkbox and set the encoding to be the fastest, and press the OK button.

(This setting method is useful for real time recording and you can set it according to the situation.)

 
If you record like this, the recording is done using x264 codec.

* For game recording, if the game you want to record is 64-bit, you must also install the 64-bit version of x264vfw (by default, unless you touch the option during x264vfw installation), x264vfw-Configure x264vfw64 from the Start menu. Run it and set it up as described above.

* Keep / Accept only YUV 4: 2: 0, Keep / Accept only YUV 4: 2: 2, Keep / Accept only YUV 4: 4: 4 are not supported for x264vfw setting and recording will fail when using this setting.
