계산 원리

비트레이트는 각 플랫폼이 공개한 권장 범위를 해상도 × FPS × 콘텐츠 복잡도에 맞춰 산출합니다. Twitch 파트너 / Enhanced Broadcasting은 1080p60에서 최대 8000kbps까지 허용하며, 비파트너는 실질적으로 약 6000kbps로 제한됩니다. YouTube와 Kick은 이보다 훨씬 높은 값을 허용합니다.

1.5배 업로드 규칙: 패킷 재전송이나 다른 트래픽으로 프레임이 끊기지 않도록 영상 비트레이트를 실제 업로드 속도의 최대 60%로 유지하세요.

계산 원리

The tool starts from a lookup table of base video bitrates keyed on resolution and frame rate — 720p60 is 4500 kbps, 1080p60 is 6000, and 1440p60 is 12000 — then multiplies by a content-complexity factor and clamps the result to the platform ceiling. Those ceilings are 6000 kbps for non-partner Twitch and TikTok Live, 8000 for Twitch Partner/Enhanced and Kick, and 51000 for YouTube Live. The rest of the output is fixed: CBR rate control, a 2-second keyframe interval, High profile, and 160 kbps AAC audio.

Two inputs actually move the number. Content type applies a multiplier — Talking / IRL (low motion) 0.75, Gaming (moderate motion) 1.0, Motion-heavy (FPS / racing) 1.2 — so a motion-heavy 1080p60 stream asks for 7200 kbps and is then clipped back to 6000 on non-partner Twitch. Your upload speed changes nothing about the bitrate itself; it only drives the headroom check, which wants at least 1.5 times the recommended bitrate. The encoder choice swaps only the preset string it suggests.

This is a lookup table with two multipliers, not an encode analysis. It cannot see your scene, so a static webcam and a chaotic shooter at the same settings return the same number. It assumes H.264 throughout — there is no HEVC or AV1 option — and the headroom check compares only video bitrate against your upload, ignoring the 160 kbps of audio and container overhead. Platform limits also change over time, so treat the YouTube figure as an outer bound rather than a target.

자주 묻는 질문

Why is my Twitch bitrate capped at 6000 kbps?

The Twitch (non-partner) option applies a 6000 kbps ceiling, which is what a 1080p60 gaming stream already hits. Switch the Platform dropdown to Twitch (Partner / Enhanced) to raise the cap to 8000 kbps; a chip appears telling you when the cap has clipped your number.

How much upload speed do I need to stream 1080p60?

The tool wants at least 1.5 times your video bitrate in upstream, so a 6000 kbps stream needs roughly 9 Mbps of real, wired upload. Below that you get a red warning; above it you get a chip showing your actual headroom multiple.

Should I raise the bitrate for fast-paced shooters?

Yes, and the Content type dropdown does it for you. Motion-heavy (FPS / racing) multiplies the base bitrate by 1.2 and Talking / IRL cuts it to 0.75. On capped platforms the motion-heavy figure often lands above the ceiling and gets clipped back down.

What is in the Copy as OBS settings box?

A plain-text block listing Output Mode, encoder name, rate control, bitrate, keyframe interval, preset, profile, output resolution, FPS and audio bitrate. You can paste it into notes and transcribe the values into OBS Advanced output settings field by field.

Why is the keyframe interval always 2 seconds?

It is fixed rather than calculated. Two seconds is what live platforms expect for segmenting the stream into chunks for their viewers, so the tool reports it as a constant alongside CBR rate control for every platform and resolution combination.
