Frequently Asked Questions

How large is a 4K video file?

Our 10-second 4K clip is 80MB. At typical bitrates, a 1-minute 4K video is ~400–800MB. Streaming services use adaptive bitrate (ABR) to deliver lower resolutions on slower connections.

Do all browsers support 4K video playback?

All modern browsers support 4K H.264 playback if the hardware can handle it. Actual smooth playback depends on the device's GPU and display resolution. Many laptops will decode 4K but display at their native resolution.
