1080p

What is 1080p?

1080p is video with 1080 horizontal lines of pixels, drawn progressively — 1920×1080 in 16:9, or 2,073,600 pixels per frame. It is the resolution the industry settled on as "Full HD", to separate it from the 720p sets sold as merely "HD ready".

The older 1080i carries the same frame size but splits each frame into two interlaced fields. It survives in some broadcast chains; on the web, progressive is universal.

1080p dimensions

1920×1080 is also where "2K" confusion starts: cinema 2K is 2048×1080, slightly wider than Full HD, and the two labels are often used interchangeably in marketing.

Bandwidth and data

With H.264, 1080p typically needs 5–8 Mbps depending on how much motion is in the shot — roughly 2.25–3.6 GB per hour of viewing. Fast movement, grain and confetti push it higher; a static slide deck sits far below.

This is where codec choice starts to pay real money: H.265 or AV1 hold the same quality at roughly half the bitrate, which at 1080p scale is a meaningful share of a delivery bill.

1080p against the rest of the ladder

1080p carries five times the pixels of 480p and 2.25 times those of 720p. The step up to 4K is another four times — for a difference most viewers only see on a large screen.

When 1080p is enough — and when it is not

For nearly all web video, 1080p is the sensible target. It is sharp enough for screen recordings with code or spreadsheets, cheap enough to deliver at scale, and universally supported.

Whatever you target, upload the best source you have. A platform can transcode down but cannot invent detail that was never captured.

When DRM withholds 1080p

Encoding 1080p does not guarantee anyone receives it. Under DRM, the licence can carry an output condition, and the common studio-grade rule is that Widevine L1 — decryption inside the device\'s trusted hardware — is required before 1080p is released at all. Software-decrypting L3 devices are held at 480p or 540p.

The result surprises teams that just switched protection on: the file is 1080p, the player is fine, and a slice of the audience quietly watches something blurrier. Nothing in the encoding settings caused it and nothing there will fix it.

For paid courses and internal training that strictness usually costs more than it protects. The policy is inherited from film distribution; a lesson recorded on a webcam is not a film release.

What 1080p costs against 720p

At 5–8 Mbps an hour of 1080p moves roughly 2.25–3.6 GB. At €0.03 per GB that is about 7–11 cents per viewing hour, a little over double 720p.

A thousand students through a ten-hour course: roughly €660–1,080 in delivery at 1080p against €330–540 at 720p. The question is whether the content spends those pixels. Screen recordings with code, spreadsheets or dense UI do — thin text breaks up at 720p. A talking head does not, and the second rung buys nothing but the invoice.
