About MP4 and GIF

MP4 .mp4

The universal video container, normally holding H.264 video and AAC audio. If a device plays video at all, it plays MP4.

Good for

  • Plays on effectively every device, browser and editor
  • Excellent compression at high quality
  • Streams well, and seeks quickly

Trade-offs

  • H.264 carries patent licensing obligations
  • Lossy — quality drops each time it is re-encoded
  • Less flexible than MKV for subtitles and multiple tracks

video/mp4

GIF .gif

A 1987 format that survives for one reason: it animates, and it plays everywhere without a video player. Its palette is capped at 256 colours per frame.

Good for

  • Animation that works in any browser and any chat app
  • Lossless within its 256-colour palette
  • Universally supported after nearly four decades

Trade-offs

  • 256 colours means visible banding on photographs
  • Transparency is on-or-off per pixel, so edges look jagged
  • Far larger than a real video file for the same clip

What changes when you convert MP4 to GIF

Short, small and silent by default

A GIF grows very quickly with length and frame size, so the defaults are deliberately conservative: 15 frames per second, 480 pixels tall, and the first 30 seconds of the clip. All three are adjustable, and the export is capped at a minute. The audio track is dropped — GIF has no way to carry sound at all, which is the usual reason people are surprised by the result.

A palette is built for your clip

Rather than reduce every frame to a fixed set of colours, the encoder analyses your footage first, builds a 256-colour palette that suits it, and then applies that palette with dithering to soften the banding. It is the difference between a GIF that looks acceptable and one that looks like it came from 1998. It also means a clip with one dominant colour scheme converts far better than one that cuts between very different scenes.

A video becomes an animation

The motion survives, but GIF is a far blunter instrument than video: it has no sound, and its 256-colour palette shows as banding on anything filmed. Expect the result to be larger than the MP4 it came from, despite looking worse — which is why short clips work and long ones do not.
