How to Ensure Recorded Videos Can Be Recovered Even If the App Is Force-Closed During Recording

Using oCam at work or school? A license is required, and it removes all ads, including this window. See the paid version →

When recording video with oCam, selecting the MKV container from the Codec menu allows the video file to be saved more safely even in unexpected situations. The MKV container offers excellent file stability, so even if the program closes during recording due to various issues, the file will not be corrupted and can still be played normally.

 

For example, even if oCam is force-closed during recording, or if a game suddenly crashes while recording gameplay, the video file saved in the MKV container can still be played normally. This is possible because the MKV format is designed to store data in a highly stable file structure.


On the other hand, if you use the MP4 container, the file may become corrupted and impossible to recover in the same kind of abnormal shutdown situation. For stable recording, using the MKV container is recommended.


However, there are a few things to keep in mind when playing MKV files. If you play an MKV file in Windows Media Player, the seek function, such as jumping to a specific point in the video, may not work smoothly. Playback itself works without a problem, but for better seeking convenience, it is recommended to use an external video player such as PotPlayer. PotPlayer plays MKV files reliably and also supports smooth seeking.


Also, MKV files are not supported by Naver's video upload feature. Since the Naver platform does not allow MKV uploads, you will need to use a platform such as YouTube if you want to share videos on the web. YouTube supports MKV uploads without issues and provides an environment optimized for sharing and playback.


Therefore, if you want stable recording with oCam, the most effective method is to select the MKV container from the Codec menu, use an external player such as PotPlayer for playback, and use YouTube for web sharing.

What to Do If There Is No Sound During Recording (Windows XP)

For Windows XP, normal operation may not be guaranteed because Microsoft has ended support for this operating system. (Reference)



To record system audio with oCam, it is important to enable the Stereo Mix feature in the Windows sound settings. This allows you to effectively capture the sound being played on your computer. Below is a detailed explanation of how to set up Stereo Mix to record system audio.


First, open the Windows Control Panel and double-click the 'Sounds and Audio Devices' icon. You can do this by opening Control Panel from the Start menu.



The 'Volume Control' window will then appear. In this window, click 'Options' on the top menu and then select 'Properties'. When the Properties window opens, select the 'Recording' option, and in the 'Show the following volume controls' section at the bottom, check the 'Stereo Mix' item. Then click the 'OK' button to save the setting.


After completing the setup, the 'Stereo Mix' item will appear in the Volume Control window. Check the 'Select' checkbox for this item and raise the volume slider to the maximum, and the sound played on the computer will be captured together when recording with oCam. With this setting, you can record game audio, music, or other system sounds.


However, Stereo Mix may appear under a different name depending on your computer's sound driver or system settings. Below is a list of device names that perform the same function as Stereo Mix. If one of the items below appears on your computer, select that device and configure it in the same way:  

- Stereo Mixer (Stereo Mixer)  

- Mixed Output (Mixed Output)  

- Stereo Mix (Stereo Mix)  

- Mixed Out (Mixed Out)  

- Stereo Output (Stereo Output)  

- What U Hear (What U Hear)  

- Stereo Out (Stereo Out)  

- Loop Back (Loop Back)  

- Digital Mixer (Digital Mixer)  

- Post-Mix (Post-Mix)  

- Digital Mix (Digital Mix)  

- Sum (Sum)  

- Wave Out Mix (Wave Out Mix)  

- Wave Output Mix  

- Wave / MP3 (Wave Output Mix)


After following the steps above to enable Stereo Mix and adjust the volume appropriately, set oCam to record system audio and you will be able to record the sound you want clearly. If the Stereo Mix item does not appear, it is recommended to check whether your sound driver is up to date or install the latest driver from the manufacturer's website.
