Change the shape while you trim
Turn a wide MP4 into 9:16 for Shorts, Reels or TikTok or 1:1 for Instagram, or keep it 16:9 for YouTube.

Smooth where you cut
Each trim point gets a crossfade, wipe or zoom automatically instead of a hard jump.

Captions in the same pass
Word-by-word captions and text overlays go on the trimmed clip, timed to the speech.
CCWho it's for
Cut an MP4 down to the part you need, wherever it's going
Most files run longer than the job needs. VIDIO trims each one to the right length and shape, then saves it as an MP4 again.
