Use the video player to navigate and press Cut Frame to extract screenshots.

Fine-tune current frame

Time

Frame

Drag the bar above horizontally to adjust video position

Captures screenshots at regular time intervals. Lower value creates more images, higher value creates fewer.

Interval

Identifies scenes and visual changes
- Aims to capture one frame per scene.
- It's not perfect, but provides a good foundation.
You can fine-tune a frame with buttons below it.

Algorithm

Hist Thresh

Compares color and brightness distribution between frames. Higher threshold means more sensitivity to changes.
Default value: 50%

Pixel Thresh

Measures the percentage of pixel changes between frames. Higher threshold means more sensitivity to changes.
Default value: 50%

Choose a grid size for screenshots. After generating, you can fine-tune the captured frames.

Pilko Studio

Pilko Studio is a frame capture web tool that lets you extract screenshots from your videos in many different ways locally within your browser.

Extraction Modes

  • Manual
    Manually select and capture specific frames from the video player.
  • Interval
    Extract frames at regular time intervals (seconds).
  • Smart Auto
    Use different frame comparison algorithms to capture only significant frame changes.
    • 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.

Features

  • See basic video metadata.
  • Automatically detect and remove black bars.
  • Different capture formats (PNG, JPEG, WEBP) and quality sliders (1-100%).
  • Preview and fine-tune captured frames with buttons or hotkeys.
  • Download individually or as a .zip -file.

Processing & Privacy

All video processing and screenshot extraction happen locally within the browser, with no cloud or server-side dependencies, ensuring your privacy.
This website already performs all processing locally, but you can download the .html file and run it locally offline with the same functionality for full peace of mind. View the source code on GitHub.
