Resolution

What is it?

Resolution is the size of the picture in pixels — how much detail the frame can hold. The familiar labels: 1080p (Full HD), 720p (HD), 480p (SD), and 4K. Higher resolution = more detail, but only if there's enough bitrate to feed it.

There's also orientation: 16:9 horizontal (TV/YouTube style) versus 9:16 vertical (TikTok/Reels/Stories style) — same idea, rotated for phones.

Practical example

A creator streams "1080p" but at a starved bitrate of 1,000 kbps. The result looks worse than a healthy 720p stream — muddy and smeared — because resolution promised detail the data couldn't deliver. Pairing resolution and bitrate correctly is the actual skill, not just picking the biggest number.

Key things to know (non-technical)

• Resolution and bitrate are a couple: raising one without the other backfires.
• Most live audiences watch on phones, where 720p often looks indistinguishable from 1080p — and costs half the bandwidth.
• Vertical vs. horizontal is a product decision: a social-native live tool must treat 9:16 as a first-class citizen, not a cropped afterthought.
• 4K live is still a premium niche: expensive at every step (encode, deliver, watch).

In Tupic Live

Tupic Live should support both orientations natively — vertical full-screen for phone-first social broadcasts, horizontal for show-style productions — and default resolutions that match real audience devices rather than the biggest spec.
