Drop your file onto the page or click Select Video. MP4, MOV, MKV, WebM and other common video formats are supported.
Pick a preset speed from 0.25x to 4x, or type a custom value between 0.1 and 16. Use the live preview to check the result before processing. You can also choose the output format.
Click Change Speed. The video is re-encoded at the new speed entirely in your browser - nothing is uploaded. When it finishes, download your sped-up or slowed-down video.
Speeding up a video is useful for creating timelapses from long recordings, skipping through filler in tutorials or lectures, and condensing surveillance or dashcam footage for quick review. Slowing a video down helps with analysing sports techniques frame by frame, creating dramatic slow-motion effects from regular footage, and studying fast-moving processes in detail. VidShift re-encodes both the video and audio tracks so the result plays back smoothly at the new speed.
Drop or select your video file on this page. Choose a speed preset (such as 2x or 4x) or enter a custom speed, then click Change Speed. The processing runs entirely in your browser - no upload, no signup, no cost. When it finishes, click Download to save your sped-up video.
Yes. Select a speed below 1x, such as 0.5x (half speed) or 0.25x (quarter speed). The duration preview will show you how long the resulting video will be. Slowing down a video is great for analysing fast action or creating dramatic slow-motion effects.
The video is re-encoded at high quality when the speed is changed. For most uses, the output is visually very close to the original. Speeding up a video reduces the total number of frames, while slowing down stretches the existing frames over a longer duration.
You can set any speed between 0.1x (ten times slower) and 16x (sixteen times faster) using the custom speed input. The preset buttons cover the most common speeds from 0.25x to 4x.
Set the speed to 4x, 8x, or even 16x to create a timelapse effect. Higher speeds compress more time into a shorter clip. For the best timelapse results, you may want to trim the video first to select just the section you want, then speed it up here. You can also extract key frames to create a photo sequence instead of a video timelapse.
The audio pitch changes with the speed - at 2x speed, audio will sound higher-pitched, and at 0.5x it will sound lower. If you do not want the audio, you can mute the video before or after changing the speed.
VidShift supports all common video formats as input: MP4, MOV, MKV, WebM, OGV, M4V, and MPEG-TS. You can output the speed-changed video as MP4, WebM, or MKV.
