Video Tools

Video is where "nothing is uploaded" stops being a slogan and starts being the whole point. A three-minute clip off a phone is 200-400 MB; every other site wants that pushed up a home broadband connection before it will even look at it, and then pushed back down again. Everything in this category reads the file where it already is, on your own machine.

It also turns out that a lot of video work does not need re-encoding at all. A phone sensor always records landscape; when you hold the phone upright, the camera does not rotate a single pixel, it writes a 3x3 display matrix into the file's tkhd box saying "turn this 90 degrees on playback". A clip that plays sideways has usually lost that matrix somewhere. Putting it back is eleven bytes and half a second, at any file size, with the picture untouched. When a real pixel rotation is unavoidable, the encoding runs on your graphics hardware through WebCodecs rather than a 30 MB software decoder.
