What is Video Frame Extractor?

Video Frame Extractor is a tool for saving specific moments from a video as PNG images. In addition to normal playback, it lets you move through the video frame by frame and adjust playback speed to capture the timing you want more precisely.

It is useful for documentation screenshots, thumbnail candidates, and checking specific scenes from a video. All processing stays in the browser.

How to Use

1. Load a video file.
2. Move to the scene you want using playback, the seek bar, or frame stepping.
3. Press the Capture button or use the S key.
4. Review the captured frames in the list.
5. Save individual frames or download them all as a ZIP file.

You can also click the video itself to toggle play and pause.

Main Controls

Playback and Navigation

• Space: Play / pause
• ←: Move back by about 1/30 second
• →: Move forward by about 1/30 second
• Seek bar: Jump to any point in the video

Frame stepping is helpful when you need to line up a very specific moment.

Playback Speed

You can choose from 0.25×, 0.5×, 1.0×, 1.5×, and 2.0×.

• Slower speeds help with fast-moving scenes
• Normal speed works for general review
• Faster speeds help when searching through longer videos

What You Can Review in the Capture List

Each captured frame includes:

• Timestamp
• Image dimensions
• Individual save action
• Delete action

This makes it easier to keep several candidate frames and remove the ones you do not need later.

Use Cases

• Creating screenshots for tutorials or documentation
• Extracting thumbnail candidates from a video
• Checking short moments in gameplay or motion graphics
• Saving multiple frames for comparison during review

Things to Keep in Mind

• Output is always PNG
• Video playback depends on formats supported by the browser
• Frame stepping uses 1/30 second increments, so it does not always match the source video's exact frame rate
• Large videos can take longer to load or capture
