Video speed changer (speed up/slow down)
Online video speed changer
Welcome to a free online tool for changing video playback speed. You can use it to accelerate (speed up) or slow down any video file, e.g., to make a slow-motion video.
To use this tool, upload your video file and set a speed multiplier.
A value less than 1 will reduce the playback speed; greater than 1 will increase it.
So if you want the file to run at half of the original speed, enter 0.5, and so on.
You can specify the start and end times to change speed only for a selected part of the video. Leave both fields empty to change speed for the entire video.
For sound, you can choose to keep the audio track at the original pace, change the speed together with video, or mute the audio altogether.
