How a film gets ready to stream
Streaming apps never send one big file. They send small pieces, at the quality your connection can carry right now.
- 1
Measure the film
Three short samples show how much detail it has. A quiet drama needs far fewer bits than a fight scene.
- 2
Encode the ladder
The same film, four times: 1080p, 720p, 480p and 360p, each capped to what this film actually needs.
- 3
Cut into 6-second pieces
Every version is cut at the same moments, with a keyframe every 2 seconds, so the player can jump between them.
- 4
The player picks, piece by piece
When the signal drops, the next piece comes from a lighter version. No buffering wheel, no restart.
Three samples, bits needed for the same look

The ladder for this film
Every version, cut at the same moments
One row per version, 1080p at the top. A 72-second clip is 12 pieces of 6 seconds, and every version breaks at the same moments.

Encode for streaming
One film in, a streaming package out: four versions in small pieces, and a playlist that ties them together.
- Your own streaming app or website
- Smooth playback on slow connections
- Pay for less storage and bandwidth, film by film
Which codec
| Codec | Size, same look | Plays on | Making it |
|---|---|---|---|
| H.264 | The usual size | Everything | Fast |
| H.265 | About 40% smaller | Most phones, TVs and Macs from recent years | About twice as long |
| AV1 | About half the size | New browsers, Android and smart TVs | The slowest |
