Pilko Studio
Pilko Studio is a frame capture web tool that lets you extract screenshots from your videos in many different ways, manual or automate, locally within your browser.
Extraction Modes
Manual Manually select and capture specific frames from the video player.
Interval Extract frames at regular intervals (frames or seconds).
Automatic Detects scene changes or use a transcription file to capture frames.
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.
Transcription captures a frame for each timestamp segment. You can fine-tune and remove these segments manually. You need to upload a separate transcription file (SRT or VTT) to use this feature.
Grid Generate a grid of screenshots into a single image.
Features
100% mobile compatible.
Supports professional workflows (TC, SMPTE, text and image overlays).

Processing & Privacy
All video processing and screenshot extraction happen locally within the browser: NO cloud processing, NO installations, NO server-side dependencies, ensuring your privacy. 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; Download or view the source code on GitHub.
