How to take a screenshot from a video?

The simplest method is to pause the video at the exact frame you need. Then, just use your computer's built-in screenshot command. For Windows, press Windows Key + Shift + S to select the area you want to capture. On a Mac, the equivalent is Command + Shift + 4.

However, for the best quality, check your video player itself. Programs like VLC often have a 'Take Snapshot' option in the 'Video' menu. This captures the original frame directly from the source file. The result is usually much sharper than a standard screen capture.
