Freeze Frame Video Effect
Pick a moment, hold that frame as a still for as long as you like, then let the video roll on — all in your browser. Nothing is uploaded.
About this tool
The freeze-frame effect pauses the action on a single frame: the video plays normally, stops dead on the moment you choose, holds that frame as a still for a set number of seconds, then carries on from the same point. It's the classic "…and everything stopped" beat used in trailers, sports highlights, reaction reels, and tutorials.
Pick the freeze point (a timestamp in seconds) and how long to hold it, then run the tool. Everything happens locally in your browser with ffmpeg compiled to WebAssembly — your video is never uploaded to a server.
Worked example
Say you have a 6-second clip and want the action to stop at the 2-second mark and hold for 3 seconds:
- Freeze at (seconds):
2 - Hold for (seconds):
3
The result is a 9-second video: it plays 0 → 2s as normal, freezes the
frame at 2s for 3 seconds, then plays the remaining 2 → 6s. The output is always
exactly hold seconds longer than the source.
How it works
Under the hood the clip is split at your timestamp. The first part plays up to the
freeze point and then clones that last frame for the hold duration (ffmpeg's
tpad filter, at the source frame rate — no frame-rate guessing). The second part
is the untouched tail. The two are joined back into a single H.264 video.
FAQ
How long can the freeze last?
You can hold a frame for up to 60 seconds. The output video ends up exactly that many seconds longer than your source. If you leave the field at its default it holds for 2 seconds.
What happens to the audio?
The output is video-only — audio is dropped. A freeze-frame is a visual effect, and cleanly re-timing an audio track around an inserted still (silence during the hold, then the rest shifted later) is out of scope here. If you need the soundtrack, add it back with a separate audio tool after freezing.
Which video formats can I use?
MP4, MOV, WebM, and MKV all work as input. The video is re-encoded to H.264 (the split-and-join can't stream-copy). MP4, MOV, and MKV keep their container; other inputs (such as WebM) come out as MP4.
What if my freeze time is past the end of the clip?
If the timestamp is beyond the video's length, the last frame is held instead
— you can't freeze a frame that doesn't exist. Set the freeze point to 0 to hold
the very first frame as an intro still.
Is there a file-size limit?
The page processes videos up to about 25 MB entirely in your browser, so short clips work best. Larger or longer videos are slow to encode in WebAssembly — trim first if needed. Nothing is uploaded; all processing is local.
