OBS 'Failed to initialize video' means its video renderer could not start. On Windows, confirm the PC uses Windows 10 or 11 with a DirectX 10.1-compatible GPU, install the current graphics driver from the GPU manufacturer, and launch the current official OBS build from its normal shortcut without old compatibility or renderer flags. If the GPU does not meet OBS's requirement, newer supported hardware is the fix.
Save the exact message and note whether OBS fails before its main window appears. Record the Windows version, complete GPU model, and whether the failure began after a driver, OBS, compatibility-mode, or shortcut change.

Check the current OBS requirements
Confirm the PC runs Windows 10 or Windows 11 and the exact GPU supports DirectX 10.1. OBS says meeting this minimum only allows the program to function; it does not guarantee that a chosen recording or stream can be sustained.
Download the current stable driver for the exact GPU from NVIDIA, AMD, Intel, or the computer manufacturer. Install it, restart Windows, and try OBS once from the normal Start menu shortcut. Do not use a generic driver site.

Remove only old OBS launch overrides
If an OBS shortcut was changed, open its Properties and remove only custom compatibility-mode or renderer parameters added before the failure. Keep the installed files and scene data unchanged, then retry a default launch.
5
Refresh OBS from its official installer
If the PC meets the requirement and the current graphics driver still fails, download the current Windows installer from obsproject.com and install it over the existing OBS copy. Do not delete scenes, profiles, or configuration folders for this test.
Success means OBS reaches its main window twice without the initialization message. Make a short blank-scene recording, then use Help > Log Files > Upload Current Log File if support is still needed. If OBS never opens, send support the exact message, GPU model, Windows version, driver version, and the failed default-launch result.
If it does not work
If the GPU lacks DirectX 10.1 support, do not install an obsolete OBS build or replacement graphics DLL; use supported hardware.
If OBS opens only through a custom OpenGL or compatibility shortcut, preserve that result and ask OBS support to diagnose the renderer instead of treating the workaround as fixed.
If the problem started immediately after a GPU-driver update, use the GPU or computer maker's supported rollback path and report the exact driver versions.
