Video Frame Extractor

What this tool does

Saves one scene of a video as an image, or takes images from a chosen range at a steady interval and saves them as a ZIP. Useful for making thumbnails or collecting scenes.

Steps

Saving just one

1. Upload a video, play it and pause at the scene you want.
2. Set the width and output format and press "Save current frame as image".

Taking many from a range

1. Set Start/End (sec) by typing or with the "Use current position as start" / "Use current position as end" buttons.
2. Set "Frames per second", the width and the output format. The number to take and the output size are shown below.
3. Press "Extract range" and thumbnails appear. Save them with "Download all as ZIP" or send them to the workbench.

Settings

• Frames per second: choose from 0.2, 0.5, 1, 2, 5, 10. The count is (range length x this value) rounded down, plus 1, at least 1.
• Width: initially the video's width as is. The height follows the ratio.
• Output format and quality: PNG has no quality loss. JPG and WebP let you set the quality. JPG has no transparency, so it is saved with a white background.

How it works

It moves the video to each time in the chosen range, draws the picture at that moment on an output-size canvas and encodes it as an image in the chosen format. Times are the start plus steps of the interval (1 ÷ frames per second), limited so they do not go past the video end. File names are "videoname_4digitnumber_times.extension".

Good to know

• You can take at most 300 at once. If more, shorten the range or lower the number per second.
• Only the first 60 thumbnails are shown on screen; saving includes all of them.
• The scene taken is the picture at a position the browser can seek to, so it may differ very slightly from the requested time.
• Video formats the browser cannot play cannot be read.
• Results are gone when you close the tab.
