Cut Video Online

Flippy opens the container, finds the data packets between your two handles, copies them into a fresh container and rebases the timestamps so the clip starts at zero. Nothing is decoded along the way, which is exactly why nothing is lost.

The one constraint: compressed video can only be entered at a keyframe, the periodic full pictures stored between the cheap in-between frames. So the start of your cut snaps to the nearest keyframe, typically within a second of where you aimed. That snap is the entire price of a lossless cut.

Frame-exact cutters exist: they re-encode the whole clip so they can start anywhere, which is slower and spends a generation of quality. For trimming recordings and pulling highlights, the lossless snap is almost always the better trade.

Most 'my video is too big' problems are really 'my video is too long' problems. Every platform cap is a budget of bitrate times duration, so removing thirty dead seconds does more for quality than any encoder setting: the footage you keep inherits every bit the trimmed part was hogging.

That makes cut-then-compress the order that wins. Cut the recording down to the moment that matters (the cut itself is lossless and takes seconds), then hand the short clip to the compressor, or to a compress-to page (8, 10, 25 or 50 MB) when a platform has drawn a hard line. Sixty tight seconds under 8 MB look dramatically better than five loose minutes squeezed to the same size.

The same order helps beyond size caps: meeting recordings lose the waiting-room minute, screen recordings lose the fumbling at the start, gameplay loses everything except the play. And because Flippy's cut is a stream copy, you can slice as often as you like without ever spending a generation of quality.
