Still have questions?
We got you!
How can I speed up a video online?
The most efficient way to speed up a video online is to upload your file to Flixier and use the speed slider in the video properties menu. You can increase the playback rate up to 5x.
How can I slow down a video for slow motion?
To create a slow-motion effect, select your clip on the Flixier timeline and adjust the speed setting below 1x. You can slow down videos to 0.2x for a smooth dramatic effect.
What is the best free online video speed changer?
Flixier is one of the best because it offers integrated pitch correction. Unlike basic tools, our platform ensures your audio sounds natural, providing a professional-grade editing experience directly in your web browser.
Does changing video speed affect the audio pitch?
By default, changing speed can distort audio, but Flixier includes an automated pitch correction feature. When you speed up a video or slow it down, you can keep the voice sounding natural, which is essential for maintaining the professional quality of tutorials, interviews, and vlogs.
Can I speed up specific parts of a video?
Yes. You can use the cut tool to isolate a specific segment on the timeline and then apply a different playback rate to just that section. This allows you to create dynamic edits where you slow down the video for a few seconds and then immediately transition back to normal or high speed.
What video formats are supported for speed changes?
Our speed editor supports all mainstream professional formats, including MP4, MOV, AVI, and MKV. You can upload high-resolution footage from any device without worrying about compatibility issues or the need for time-consuming file conversions before you start editing.
