When to Change Video Speed
Slow Motion (0.25× – 0.5×)
Sports highlights, dance moves, product demos, nature footage. Anything where you want viewers to catch the detail.
Speed Up (1.5× – 2×)
Tutorials, cooking videos, time-lapses of work. Cut a 10-minute process to 5 minutes without losing context.
Reverse Playback
Rewind effects, creative transitions, or just because it looks cool. Works great with water, falling objects, or walking.
Looping
Seamless background videos, extending short clips for presentations, or making GIF-style loops without converting to GIF.
Tips for Social Media
TikTok/Reels: 0.5× slow-mo on the drop of a song is a classic effect. Speed up setup/prep footage to keep viewers engaged.
YouTube: Many viewers watch at 1.5× or 2× anyway. If your content is information-dense, a slightly faster pace (1.25×) can feel more energetic without being rushed.
Podcasts with video:Enable "Preserve audio pitch" when speeding up. Otherwise voices sound chipmunk-y.

Frequently Asked Questions
What speed options are available?
0.25× for dramatic slow motion, 0.5× for half speed, up to 4× for fast forward. You can also set any custom speed between 0.1× and 5×.
Will speeding up make the audio sound weird?
Not if you enable 'Preserve audio pitch'. This keeps voices sounding natural even at 2× speed — like podcast apps do.
Can I play my video backwards?
Yes. Toggle 'Reverse video' and it plays in reverse. Combine with slow motion for those satisfying rewind effects.
What about looping?
Set loop count from 1× to 10×. Good for making seamless loops or extending short clips.
What's the file size limit?
500MB. Most phone videos are well under this. Output is always an optimized MP4.
Any watermarks or branding?
None. The output is your video, processed — nothing added.
