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.

The format for file names may seem difficult for some users. Here are some examples.
-If the file name is _ <#>, is the initial letter and # is the serial number.
The initial letter is replaced by Record when recording, Record when recording, Capture when capturing, and # is replaced by serial number.
For example, if the screen is recorded, a file named Record_1 is created. (However, if there is no file with similar format in OCAM storage folder)
When you record again, a file named Record_2 is created. The reason for the serial number is 2 because the file named Record_1 already exists.
-If the file name is _ <#>, represents the program name to start recording, and is replaced with the name oCam during normal screen recording, and <#> is numbered in the form of a serial number as before. .
However, if you record a game, the recording starts in the game program, so it is created with the name of the game's executable file.
-If the file name is _ <#>, dddddd stands for localized date. When using Korean operating system, it will be replaced by Thursday, June 16, 2016. Enter.
The localized date depends on the language setting of the operating system. In other words, it is displayed differently in the English OS and uses the format built into the operating system.
-If the file name is My _ <#> _ th_ _ file, the file will be created with the name of my_1th_record_file when recording, and if you record again, it will be my_2_record_file. The file name is generated.
-The file name played on on . If "Advanced developer recorded a game called LocalDeformablePRT on Thursday, June 16, 2016." Can be generated as The content inside <> depends on what you record.
Serial number start indicates the serial number start number that can be set with # inside <>.
