Frequently asked questions
Can I speed up video without uploading?
Yes. The selected video is processed locally in your browser tab.
Does the audio speed up too?
Yes. Audio timing is changed with the video.
Is this the same as trimming?
No. Trimming removes time; speeding up keeps the full video but plays it faster.
