What to Do If the SecretFolder "Failed to ConnectToFilterDriver" Error Occurs
The SecretFolder program is not installing properly at the moment, so you will need to remove it manually in order to delete it completely. The steps are explained in detail below.
First, press the Windows key and the R key on your keyboard at the same time. A small input window called "Run" will then appear on the screen. Type "regedit" exactly into that window and press Enter to open the Registry Editor. The Registry Editor is a tool that can modify system settings, so please proceed carefully.
Once the Registry Editor is open, go to the following path in the tree on the left:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\SecretFolder_is1
Find the "SecretFolder_is1" key at this location, right-click it, and select "Delete" to remove the key completely. This path is mainly used on 64-bit systems.
If you cannot find the "SecretFolder_is1" key in the path above, your system may be 32-bit, so please check the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\SecretFolder_is1
At this location as well, find the "SecretFolder_is1" key, right-click it, and select "Delete" to remove it. This will clean up the registry entries related to SecretFolder.
Once the registry work is complete, you will need to delete the folder related to SecretFolder from the file system. First, open File Explorer and go to the following path:
%programfiles(x86)%\SecretFolder
This is usually the default installation path on a 64-bit system. %programfiles(x86)% typically refers to C:\Program Files (x86), and there should be a folder named "SecretFolder" there. Find that folder, right-click it, and select "Delete" to remove the folder and all files inside it completely.
If you cannot find the "SecretFolder" folder in the path above, your system may be 32-bit, so please check the following path:
%programfiles%\SecretFolder
This path, %programfiles%, usually refers to C:\Program Files. Here as well, find the "SecretFolder" folder, right-click it, and select "Delete" to remove the folder and all of its contents.
Once you complete all of the steps, the registry entries and files related to the SecretFolder program will be completely removed from your system. If you run into any issues during the process or have trouble finding the path, check whether you entered the path correctly or whether you are running with administrator privileges. By following this process, you can manually remove SecretFolder cleanly.

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.
