About Change video speed

The sound keeps its normal pitch, so voices stay recognisable rather than turning into chipmunks. Slowing down repeats frames rather than inventing new ones - there is no invented in-between motion here - so very slow speeds look stepped unless the clip was filmed at a high frame rate.

How to use it

  1. 1Drop your MP4, MOV, MKV and WebM file into the box, paste it, or tap browse.
  2. 2Adjust the settings if the defaults are not what you need.
  3. 3Run the tool. The work happens on your own device.
  4. 4Download the result.
