MP4 to Shorts
An MP4 file — recorded on a camera, exported from an editor, or downloaded from somewhere else — is raw material, not a finished Short. FrameOS uploads take any MP4 and turn it into vertical, captioned Shorts ready to publish.
Works with any MP4, regardless of source
Whether the file came from a camera, a screen recorder, a video call export, or another editing tool, FrameOS doesn't care about the origin — only that it's a video file with usable spoken or visual content to clip from.
Finds the Shorts-worthy moments automatically
A long MP4 rarely works as a single Short. FrameOS scans the full file, ranks the strongest standalone moments, and surfaces them as clip candidates instead of forcing a manual scrub through the timeline.
Reframes landscape MP4s to vertical automatically
Most MP4 exports are landscape 16:9. FrameOS reframes each selected moment to 9:16, tracking the subject so the crop doesn't cut off whoever is talking.
Captioned and exported, Shorts-ready
Every clip comes out with word-by-word captions burned in and sized for YouTube Shorts, so the export is ready to upload immediately — or send straight to a connected YouTube channel.

FAQ
Does the MP4 need to come from a specific source?
No — any MP4 file works, whether it's from a camera, screen recorder, call recording, or another editor's export.
Can it convert a long MP4 into multiple Shorts?
Yes. FrameOS finds multiple standalone moments in a longer file and can turn one MP4 into several separate Shorts.
Does it handle the vertical reframing automatically?
Yes — landscape MP4s are reframed to 9:16 automatically, tracking the subject rather than using a fixed center crop.
