[HOWTO]How to reduce the size of recorded video files during game recording (For NVIDIA codec)

If you are using NVIDIA NVENC H.264 codec by default, the recorded file may be very large.

 

If you click the codec menu of Ocam, you can check whether you are using the NVENC H.264 codec as follows.

 


 

 

In Ocam's Codec menu, click Hardware Encoder Settings.

 

Then, the following hardware encoder setting window appears, and you can reduce the size of the recorded video file by modifying the part marked with yellow box.

 

First, let's take a look at how to reduce the size of a recorded file using the variable bitrate.

(Rate control should be 1-PASS VBR as shown below.)

 

 


 

 

The quantizer value can be set from 1 to 51.

 

Lower quantizer values ​​result in better image quality; higher quantizer values ​​result in poorer image quality.

 

 

That is, the recording quality is defined by the range from the minimum quantizer to the maximum quantizer value.

 

For example,

If the minimum quantizer value is 1 and the maximum quantizer value is 13, the recording quality is 1 to 13.

If the minimum quantizer value is 1 and the maximum quantizer value is 51, the recording quality is 1 to 51.

If the minimum quantizer value is 13 and the maximum quantizer value is 51, the recording quality is 13 to 51.

 

 

In conclusion, to reduce the size of a movie recording file, the larger the minimum and maximum quantizer values, the lower the recording quality and the smaller the recording file size.

 

 

The quantizer value can be adjusted as follows.

 

To lower the quality and reduce the size of the recorded image while maintaining the maximum recording quality, set the minimum quantizer value to 1 and the maximum quantizer value as large as you want to reduce the quality.

(E.g. minimum quantizer: 1, maximum quantizer 30)

 

To reduce the size of the recorded image by reducing the image quality to the maximum in the middle while maintaining the medium quality, the minimum quantizer is 26 and the maximum quantizer value is 51.

 

 

Note that the minimum quantizer value cannot be greater than the maximum quantizer value.

That is, the minimum quantizer value <= maximum quantizer value.

 

 

Note: If you set the minimum quantizer value to 1 or the maximum quantizer value to 1, the file size of the recorded video will be huge.

The default minimum quantizer value is 1, the maximum quantizer value is 13, and it is recommended to set it within the following range.

Minimum quantizer> = 1 and maximum quantizer value> = 13

 

 

 

Here's how to reduce the size of a recorded video file using a fixed bitrate.

 

Just change the rate control to 1-PASS CBR as shown and set the average bitrate.

 


 

 

 

The larger the average bitrate size, the higher the image quality, and the smaller the size, the lower the image quality and the smaller the recorded file size.

 

 

 

Finally, using fixed quantizer parameters.

 

Set the rate control to 1-PASS fixed quantizer parameter as shown below.

 


 

 

There is no concept of minimum quantizer and maximum quantizer in VBR, and the quantizer will set the quality to a fixed value.

[Tips]In Windows 7 and later, useful tips during microphone recording

1. If you want to record microphone only, and then click the sound button in the orchestra-time main window, you can disable the check to the recording of the sound system.

 

2. If the sound is too small microphone

 

[Start] menu - [Control Panel] - After you click, click sound Recording tab, in the list of the recording device, and then double-click the microphone you are using, and then open the properties of the microphone.

Then, at the level tab as follows, using the size and microphone boost of basic volume of the microphone, you will be able to increase the size of the microphone. 

 

3. too large sound recording systems, when the sound of the microphone can not hear, 

 

In this case, to have to give the sound of the system, you can reduce in the following manner. 

 

- If there are options that can be used to adjust the volume on the program for reproducing the sound from the computer during recording, and to reduce the sound by adjusting the volume, the size of the system sounds that are recorded at the time of recording is reduced you. 

- Forced the program to play a sound, if you can not reduce the volume, the tray icon by clicking on the shape of the speaker with the right button, and then click Open Volume Mixer. 

 

Can see the list of programs that are playing the current sound as follows, so you can adjust the volume size of the program, you can adjust smaller. 

(However, it does not reduce the size of the recorded sound by reducing the volume of the speakers must be to reduce the volume size of each program.) 

 

4. You can better the sound quality of the microphone, to completely eliminate the noise, buy a professional audio interface, and according to it you can expect a good sound quality when you also purchase the microphone. 

In a typical microphone for noise or lot, poor sound quality, in terms of software, since it is impossible to improve the sound quality, it is necessary to purchase a good hardware devices.
