Video Clip Converter

About the Video Clip Converter

This turns the opening seconds of a video into a short WebM clip, entirely inside the browser: your file is played in the page while its frames are drawn to a canvas and captured with the browser's own MediaRecorder. Nothing is uploaded, which is the practical reason to use it for footage you would rather not hand to a web service. Upload an MP4, WebM or MOV, set a clip length and frame rate, and download the result. Several constraints follow from how the capture works and are worth knowing before you start. Recording always begins at the start of the video, as there is no way yet to choose a different start point. The clip is silent, since audio is not captured, and it is scaled to a maximum width of 480 pixels. Capture runs in real time with the tab in the foreground, so a five-second clip takes five seconds.

How to use it

1. Upload a video (MP4, WebM or MOV).
2. Set the clip length in seconds and the frame rate.
3. Export and download the WebM clip.

Things worth knowing

• Recording starts from the beginning of the video. There is no way to choose a different start point yet.
• The output is a WebM video file, not a GIF. WebM plays in modern browsers and most players, but some older software and a few chat platforms will not accept it.
• Audio is not included — the exported clip is always silent.
• The clip is scaled to a maximum width of 480 pixels.
• Capture happens in real time, so a five-second clip takes five seconds to record. Keep the tab in the foreground while it runs.
