Extraction Modes

• Manual
  Manually select and capture specific frames from the video player.
• Interval
  Extract frames at regular intervals (frames or seconds).
• Smart Auto
  Automatically detects scene changes and aims to capture only one frame per scene.
  • Histogram Diff compares the overall distribution of colors and brightness levels between frames. If the distribution is different enough (determined by the slider value) in a scene change, it triggers a frame capture.
  • Pixel Diff measures the percentage of pixels that have changed between frames. If the percentage is above the threshold (determined by the slider value), a frame capture will be triggered.
• Grid
  Generate a grid of screenshots to a single image.

This website already works locally and from a single .html -file (crazy, right?), but you can download the .html -file and run it locally even offline with the same functionality for full peace of mind;
