“Easy Video Speed Editor” is a simple video speed editing app that lets you easily change the playback speed of your videos. You can edit videos directly on your phone, including slow motion, fast forward, speed changes, speed-by-section editing, trimming, GIF conversion, and Live Photo export. It is useful for checking sports form, reviewing dance or golf swings in slow motion, adjusting the tempo of vlogs and short videos, and creating speed-up videos for TikTok and Instagram. ◆ Main Features ◆ ・Change video playback speed Supports standard speeds such as 0.25x, 0.5x, 1x, 1.5x, and 2x. With Pro, you can fine-tune the speed using a slider and freely edit from slow motion to fast forward. ・Change speed by section Split a video and apply slow motion or fast forward to specific parts only. Use presets such as Highlight Slow-Mo, Time-lapse, Jump Cut, Beat Drop, Cinematic Slow-Mo, Speed Up, and Slow Down to quickly create videos with dynamic speed changes. ・Smooth Slow-Mo (iOS 26 or later, supported devices) Fills in the missing frames in slowed-down parts so your slow motion plays back smoothly instead of looking choppy. Compare the original and the smoothed version side by side before saving. ・Pitch preservation and no-audio export Preserve natural voice pitch even when changing speed. Videos with conversations or narration remain easier to listen to. You can also remove audio completely and save the video without sound. ・Trimming and horizontal flip Cut unnecessary parts of a video or flip it horizontally. Keep only the parts you need and create a cleaner, easier-to-watch video. ・Multiple export formats Save as a regular video, or export as MP4, animated GIF, or Live Photo. Choose a format that works well for social media posts or sharing with friends. ・Output settings Adjust output settings such as resolution, frame rate (FPS), and whether to keep shooting information such as date, location, and camera metadata. ◆ Recommended For ◆ ・People who want to make videos slow motion, fast forward, or speed-up ・People who want to check sports, dance, or golf form ・People who want to add dynamic speed changes to vlogs or short videos ・People who want to make long videos easier to watch by speeding them up ・People who want to convert videos to GIFs or Live Photos and share them ・People who want a simple video editing app on their phone ◆ More Features with Pro ◆ With Pro, you can remove ads, fine-tune custom speeds, use Smooth Slow-Mo, unlock expanded speed-by-section editing, use all presets, and change FPS and export formats for more flexible video editing. With the lifetime purchase plan, you can pay once and use it forever. Use “Easy Video Speed Editor” to easily create the video you want, whether you need slow motion, fast forward, or speed-by-section editing. Notice ・If the output duration is too short (less than 1 second), saving the video may fail. ・When changing the speed of videos not recorded on iPhone, conversion may not work correctly in some cases.
