Create slow-motion or time-lapse effects in bulk
Meicut's video speed changer turns footage into slow motion or fast-forward, from 0.25x to 100x, one clip or a whole batch at the same speed. Pick a preset or type an exact value, and the page shows the new duration before you start.
Presets cover the common cases: 0.25x and 0.5x for slow motion, 1.5x to 4x for compressing long clips, 10x and 100x for time-lapse. The slider and number input set any value in between.
- Slow motion down to 0.25x, fast-forward up to 100x
- Presets plus a slider and exact number input
- See the resulting duration before you start
- Apply one speed to many videos in a single run
- Audio stays in sync with the video
- Works with MP4, MOV and other common formats
Common speed change needs
Slow down sports and action clips
Half speed or quarter speed stretches the action so the details are visible: a swing, a trick, a goal. Footage shot at a higher frame rate looks smoothest when slowed.
Compress a long process into seconds
A drawing, a build, a commute: at 10x or 100x an hour becomes a watchable clip. This is the classic time-lapse effect made from normal footage.
Fit a video into a time budget
The estimate row shows the exact duration at the chosen speed. Adjust the number until the length fits your slot, then export.
Speed up lectures and tutorials
A 1.5x or 2x pass through a recorded lecture halves the watching time, and the audio speeds up along with the picture, staying in sync.
Change the speed of many clips at once
Footage from one session usually needs the same treatment. Upload the clips together, set one speed, and download the adjusted set. Batch processing works with a free account; a single clip needs no sign-up.
Slow motion or fast-forward
Slow motion (below 1x)
Stretches time: longer duration, every detail of the action visible. Use it to analyze movement or give a moment weight. 0.5x doubles the length, 0.25x quadruples it.
Fast-forward (above 1x)
Compresses time: shorter duration, the process visible at a glance. Use it for builds, journeys and anything the viewer only needs in outline. 2x halves the length, 10x shrinks it to a tenth.
Frequently Asked Questions
How do I make a video slower or faster?
Upload your video and pick a playback speed: below 1x for slow motion, above 1x to speed it up. Then start processing and download the result. You can adjust several videos at once with the same speed.
Can I create a slow-motion video from normal footage?
Yes. Choose a speed like 0.5x or 0.25x to stretch the action into a smooth slow-motion effect. Footage shot at a higher frame rate will look smoothest.
What happens to the audio when I change video speed?
The audio speeds up or slows down together with the video so they stay in sync.
Can I set an exact speed instead of a preset?
Yes. Besides the presets you can drag the slider or type a value with one decimal, anywhere from 0.25x to 100x.
Can I change the speed of several videos at once?
Yes. Upload multiple videos and the same speed applies to all of them in one run. Batch processing works with a free account; a single video needs no sign-up.
What happens to my uploaded videos?
Videos are uploaded for processing, then expire and are deleted according to your account rules.
