How to Reduce the Size of Recorded Video Files When Recording Games (NVIDIA Codec)
If you are using the NVIDIA NVENC H.264 codec by default, the recorded file size may be very large.
Click the Codec menu in oCam to check whether you are using the NVENC H.264 codec, as shown below.
In the oCam Codec menu, click Hardware Encoder Settings.
The Hardware Encoder Settings window will appear as shown below. You can reduce the size of the recorded video file by changing the options highlighted in the yellow box.
First, let's look at how to reduce the size of the recorded file using variable bitrate.
( Rate Control must be set to 1-PASS VBR. )
The Quantizer value can be set from 1 to 51.
The lower the Quantizer value, the better the video quality, and the higher the Quantizer value, the lower the video quality.
In other words, the recording quality is defined by the range from the minimum Quantizer value to the maximum Quantizer value.
For example,
If the minimum Quantizer value is 1 and the maximum Quantizer value is 13, the recording quality range is 1 to 13.
If the minimum Quantizer value is 1 and the maximum Quantizer value is 51, the recording quality range is 1 to 51.
If the minimum Quantizer value is 13 and the maximum Quantizer value is 51, the recording quality range is 13 to 51.
In conclusion, to reduce the size of a recorded video file, increasing the minimum and maximum Quantizer values will lower the recording quality and reduce the file size.
You can adjust the Quantizer values depending on your needs, as follows.
If you want to maintain the highest recording quality while lowering the quality at certain points to reduce the size of the recorded video, set the minimum Quantizer value to 1 and set the maximum Quantizer value to a higher number depending on how much you want to reduce the quality.
( Example: Minimum Quantizer: 1, Maximum Quantizer: 30 )
If you want to maintain medium quality while lowering the quality as much as possible at certain points to reduce the size of the recorded video, set the minimum Quantizer to 26 and the maximum Quantizer value to 51.
For reference, the minimum Quantizer value cannot be greater than the maximum Quantizer value.
That is, the minimum Quantizer value <= the maximum Quantizer value.
Caution: If you set both the minimum Quantizer value and the maximum Quantizer value to 1, the recorded video file size will become extremely large, so do not use this setting.
The default values in oCam are a minimum Quantizer value of 1 and a maximum Quantizer value of 13, and we recommend setting them within the following range.
Minimum Quantizer >= 1 and Maximum Quantizer value >= 13
Next is how to reduce the size of the recorded video file using constant bitrate.
Change Rate Control to 1-PASS CBR and then set the average bitrate.
The higher the average bitrate, the better the video quality. The lower the bitrate, the lower the video quality and the smaller the recorded file size.
Finally, there is a method that uses a fixed Quantizer parameter.
Set Rate Control to 1-PASS Fixed Quantizer Parameter.
Unlike VBR, there is no concept of minimum and maximum Quantizer values, and the quality is set using a fixed Quantizer value.

oCam Advanced Settings - Mouse Cursor Effects - Cursor Size
oCam is powerful software that offers a variety of settings for screen recording and capture, allowing users to customize the output as needed. In the settings window that appears when you click Tools - Options, the Effects category includes options for adjusting visual effects applied during recording, and among them, the Cursor Size setting is used to adjust the size of the mouse cursor shown in the recorded video. This setting is especially useful when you want to highlight the mouse cursor in tutorials or presentation videos. Below is a detailed explanation of the Cursor Size setting in the Effects category.
Overview of the Cursor Size Setting
The Cursor Size setting adjusts the size of the mouse cursor in the recorded video, and the cursor is displayed enlarged according to the value set by the user. This setting does not affect the size of the mouse cursor shown on the actual computer screen. It applies only to the recorded video or captured image. This allows users to keep their working environment unchanged while improving cursor visibility in the video.
Adjusting Cursor Size
Cursor Size is set to 1 by default, which means the original mouse cursor size. If the user changes this value, the cursor size is adjusted as follows:
2: The cursor is enlarged to 2 times the original size.
3: The cursor is enlarged to 3 times the original size.
...: In this way, the cursor size increases proportionally according to the setting value, and it can be set up to 10, which displays it at 10 times the original size.
For example, if the cursor size is set to 5, the mouse cursor will appear 5 times larger than the original size in the recorded video, making it easier to highlight mouse movements and helping viewers identify the cursor position more easily. This feature is especially effective in instructional videos, software tutorials, or any situation where detailed clicking actions need to be shown.
Features and Notes
Applies only to recorded videos: The Cursor Size setting does not affect the cursor size on the actual computer screen. The mouse cursor you see while working always remains at its original size, and the enlarged cursor is applied only to the final output, such as the recorded video or captured image.
Visual emphasis: If the cursor size is set larger, the mouse cursor becomes more noticeable in the video, making it easier for viewers to follow important actions or click locations. For example, it is useful when showing how to click a specific button in a complex software interface.
Avoid excessive enlargement: If the cursor size is set too large, such as 8 to 10 times, it may cover other elements on the screen or reduce the overall neatness of the video. It is therefore important to choose an appropriate size based on the purpose of the content and the viewing environment.
Usage Tips
The Cursor Size setting can be used strategically depending on the purpose of the video. For example, when creating online lectures or YouTube tutorials, it is a good idea to set the cursor size to 3 to 5 times larger so viewers can clearly recognize mouse actions. On the other hand, in gameplay videos where the cursor is not a major element, using the default value of 1 or only slightly enlarging it to 2 or 3 may be more appropriate. After changing the setting, it is recommended to make a short test recording to check whether the cursor size fits well with the overall balance of the video.
Also, when used together with other oCam settings, such as the Include Cursor in Recording option in the Recording - General tab, you can adjust both whether the cursor is included and its size at the same time for more flexible customization. For example, if you include the cursor and set its size to 4 times larger, you can emphasize important actions for viewers while still keeping the video clean.
The Cursor Size setting in the Effects category of oCam is a simple but powerful visual tool that plays a major role in improving the readability and effectiveness of videos.
