About reverse video on Cicadas

Play a video backwards: choose an MP4, MOV or WebM your browser can play, set the part to reverse (up to 60 seconds), choose backwards or boomerang, a frame rate, a size and a speed, and download the MP4. The sound is reversed together with the picture, or you can choose No sound. The video is decoded and encoded on your device; nothing is uploaded. The tool is free, adds no watermark, needs no account and uses no credits.

Why use Cicadas for reverse video

Backwards or boomerang

Play the clip in reverse, or forwards and then backwards for a loop that comes back to its start. Pick 24 or 30 fps and 0.5×, 1× or 2× speed.

The sound goes backwards too

The sound of the part you chose is reversed with the picture and written into the MP4 as AAC. In a boomerang it plays forwards and then backwards; at 0.5× or 2× it slows down or speeds up with the picture, so its pitch moves too. Choose No sound for a silent MP4.

Reverse a video with no upload

No account, upload or credits: your browser decodes each frame and encodes the MP4 on your device. Set a start and end time (up to 60 seconds and 1,800 frames) and choose 480p, 720p or 1080p, never larger than your video. The result lives only on this page, so download it before you leave or refresh.

Reverse video FAQ

Tested on Cicadas · reviewed 2026-10-02

Tested in Chrome on 2026-10-01 and 2026-10-02. Picture: 5 seconds of a 1080p clip reversed at 720p and 30 fps took about 15 seconds and gave 150 frames; the first frame matched the last moment of the source (33.7 dB PSNR, against 13.5 dB for the first moment) and the last frame matched the first. Sound (2026-10-02): 5 seconds of an 848 × 480 clip reversed with sound in about 4 seconds; ffprobe read H.264 plus AAC (48 kHz stereo) of equal length, and the output sound played backwards again lined up with the source at zero offset (correlation 1.00; 0.09 when compared forwards). A 2× boomerang of 3 seconds of a vertical clip came out as a 3-second MP4 at 60 fps whose sound runs forwards, then backwards, an octave up. Sound is written with the browser's AAC encoder (Chrome, Edge); where that is missing the MP4 is silent and the page says so. Decoding depends on your browser's codec support.
