How to Record Losslessly Using x264vfw
Using oCam at work or school? A license is required, and it removes all ads, including this window. See the paid version →
Before getting started, you must install the x264 codec in advance. If you do not know how to install it, please refer to the Help section.
Click the Codec menu in oCam, then click the External Codec menu item.
Select Use External Codec, choose the x264vfw codec, and then click the Settings button.
Using the default x264vfw settings as a base, change the parts highlighted in the yellow box in the image below as shown.
The following settings need to be changed.
Preset - Ultrafast ( Set this to improve encoding speed. The file size may become larger, but if you choose other options, significant lag may occur. )
Profile - High 4:4:4 ( The default profile may cause quality loss, so change it to High 4:4:4 for lossless encoding. )
Keep input colorspace - Keeps the color space of the internally received input buffer. ( If you use other options, encoding may fail. )
Rate control - Single pass - lossless - Change this for lossless encoding.
Click the OK button to apply the settings.
When recording 64-bit games, the settings are applied to x264vfw64 for 64-bit, so run x264vfw - Configure x264vfw64 from the Start menu and configure it in the same way as shown above.
If you record with the above settings, the video will be recorded losslessly. One important point is that if you want to play back the lossless video without quality loss, you must change the settings in your video player.
Below is how to check a lossless video using PotPlayer.
Run PotPlayer, then click Preferences ( F5 ).
In the Preferences window,
click Video - Color Space/Attributes on the left, then in the Color Space group box on the right, select Convert manually if possible - Default output color space. ( If you do not configure this, even if the recording is lossless, the screen colors may still be altered during playback. )
Click OK, then play the video recorded losslessly.
At this point, press Ctrl + F1 in PotPlayer. As shown below, the output format of the video codec must be displayed as RGB(32 Bits).
Also, in the playback information under the File Information tab, the following properties must match as shown below.
Format profile : High 4:4:4 Predictive@L3
Color space : RGB
Color range : Full
Matrix coefficients : RGB
Please note that Windows Media Player does not play this properly, and preview thumbnails will not be displayed in Windows Explorer.

oCam Advanced Settings - Mouse Cursor Effects - Click Effects
Click Tools - Options on the oCam main menu to open the settings under the Effects category.
Click Effects lets you apply separate effects when clicking the left mouse button and the right mouse button.
The available options for click effects are as follows. Below is an overview of each option.
The Style option supports five different styles.
1. Ring
2. Star
3. Star (Random Colors)
4. Rotating Star
5. Rotating Star (Random Colors)
Color is the color used for the click effect, and the selected color is ignored when Random Colors is used.
By default, it is red. For example, if the style is Ring and you change the color to black, it will appear as shown below.
( Note: The highlight animation starts slightly to the left of the text cursor, and this is normal. This is because the click position of the text cursor is slightly to the left. )
Animation Duration refers to how long the mouse cursor effect remains visible.
If the animation duration is set to about 0.5 seconds
If the animation duration is set to about 2.5 seconds
Size and Line Thickness refer to the size of the shape and the thickness of its outline, depending on the selected style.
If you increase the size to 150 and set the line thickness to about 20
Finally, the area shown below is the preview window where you can preview the options you have selected.
If you move the mouse over the preview area shown above and left-click or right-click, you can preview the click effect.
