About this app

Got long videos full of dead moments? ChoPPer finds them and cuts them out for you.

Pick several clips, tap "Edit video" and ChoPPer analyzes the motion in each video, trims the parts where nothing happens and joins everything into a single video, ready to share. No timeline, no manual trimming, no learning curve.

▶ TRULY AUTOMATIC
Our motion detector marks the parts with action and drops the dead ones. You only adjust two controls —sensitivity and margin— and see the before/after instantly. ChoPPer reviews the whole video to find the action, so processing time depends on the length of the original.
Filmed handheld? Switch to Sound mode and ChoPPer cuts by silences instead, so camera shake doesn't matter.

▶ JOIN SEVERAL VIDEOS
Combine several clips into one, in the order you want. Reorder them with a tap.

▶ 100% ON YOUR PHONE · PRIVATE
ChoPPer processes everything on your phone. It doesn't upload your videos to any server, works offline and doesn't even ask for internet permission. Your videos stay yours.

▶ KEEPS THE QUALITY
No downscaling. It keeps the original resolution and adjusts the bitrate so the result looks like the original.

▶ WITH OR WITHOUT AUDIO
Turn on "Keep audio" for vlogs, gameplay or music; turn it off for quick joins of silent clips.

▶ SAVE AND SHARE
Built-in preview, save to your gallery (in the folder you choose) and share to any app with one tap.

GREAT FOR
• Vlogs and travel videos
• Gameplay and match clips
• Sports and action
• Tutorials and recipes (top-down POV)
• Any video with dead time

Download ChoPPer and turn long, boring videos into snappy edits in seconds.
