Edit video speed in seconds — slow down, speed up, or batch-export a whole stack. Preview, then save to Photos.

Change Video Speed is a simple video speed editor for iPhone and iPad. Adjust playback from 0.25× to 4×, mute or keep audio, and export in a tap. Most speed apps force you to process clips one by one. Pro batch export does up to 10 at once.

KEY FEATURES
• Batch export (Pro) — change the speed of multiple videos in one tap. Ideal for reels, sports series, and drone dumps
• Speed up clips for vlogs, reels, and time-lapse style pacing (up to 4×)
• Slow motion down to 0.25× for sports, action, and detail
• Real-time preview before you export
• Keep original audio or mute it
• Import from Photos or Files (Downloads, iCloud Drive, USB)
• Save to Photos and share to Instagram, TikTok, WhatsApp, and more

PRO FEATURES
• Batch export up to 10 videos at the same speed
• Every speed unlocked (including above 1.25×)
• High-definition export, no ads
• Segment speed — apply different speeds to different parts of a clip

WHO IT’S FOR
Content creators, social media managers, drone videographers, students watching lectures faster, sports slow-mo, travel time-lapse, and anyone tired of exporting one file at a time.

HOW IT WORKS
1. Choose a video from Photos or Files — or open Batch Export
2. Set speed with presets or the slider
3. Preview
4. Export one clip, or export the whole batch to Photos
