Video Speed Editor & Changer

Video Speed Editor & Changer lets you speed up or slow down any video from 0.1x to 16x, preview it instantly, and save it as a new MP4 with no watermark. Create slow motion replays, fast motion time-lapses and speed ramps in a few taps, fully offline.

Pick a video, drag the speed slider, watch the preview, tap Save. That is the whole workflow. No account, no upload, no logo on your video.

⏱️ ANY SPEED FROM 0.1x TO 16x
Slow motion down to 0.1x, fast motion up to 16x, or any value in between with the slider and fine-tune buttons. Quick presets for 0.25x, 0.5x, 0.75x, 1.25x, 1.5x, 2x, 3x, 4x, 8x and 16x.

🎢 SPEED RAMP: CHANGE ONLY PART OF THE VIDEO
Select the section that gets the speed change on the thumbnail timeline. Slow motion for the highlight, normal speed for the rest, all in one clip. The preview plays the selection at the new speed so you can check it before saving.

🎵 KEEP THE PITCH
Voices and music stay natural when you change video speed: no chipmunk effect when speeding up, no deep drawl when slowing down. Turn it off for the classic funny effect.

✂️ CROP & VOLUME
Crop to 1:1, 4:5, 9:16, 16:9, 3:4 or 4:3 for Reels, Shorts, TikTok and Stories. Boost the volume up to 200% or mute the audio completely.

🗂️ BATCH VIDEO SPEED CHANGER
Select many videos, set the speed, crop and volume once, and export them all in one go with per-video progress.

📥 LOAD FROM ANYWHERE
Pick from your gallery or Google Photos, record a new clip with the camera, or share a video into the app from any other app.

🔔 EXPORT IN THE BACKGROUND
Start an export and keep using your phone. A notification shows the progress and tells you when the video is ready.

💎 HIGH QUALITY, NO WATERMARK
Hardware-accelerated processing keeps the original resolution. The output is a standard MP4 saved to your Movies folder, ready to share to Instagram, YouTube, WhatsApp or TikTok.

🔒 PRIVATE & OFFLINE
Everything is processed on your device. Your videos are never uploaded. Works in airplane mode.
