Video bitrate

The data budget that decides how much detail survives.

By Thomas Linck, founder · Updated June 2026

Video bitrate is the amount of data spent per second of footage, measured in Mbps. Too low and the encoder throws detail away — macroblocking and smeared motion, worst in fast action, confetti and water. YouTube's recommended upload bitrates (H.264, SDR) are about 8 Mbps for 1080p30, 12 Mbps for 1080p60 and 35–45 Mbps for 4K.

WHY IT MATTERS

Every platform re-encodes your upload, so your export is the raw material its compressor starts from. A thin bitrate stacks compression on compression, which is exactly where the smear and the blocky shadows come from. Going far above the recommendation buys little, because the platform squeezes the file down its own ladder anyway — aim for headroom, not maximum file size.

TARGET · STANDARD

1080p · 30 fps	≈ 8 Mbps	YouTube floor; ~16 for headroom
1080p · 60 fps	≈ 12 Mbps	more frames, more data
4K · 30 fps	35–45 Mbps	detail is hungry

How CutScore measures it CutScore reads the real bitrate, codec and resolution of your exported file, compares them to the platform target, and flags an export too thin to survive re-encoding — before the upload, not after. Targets follow YouTube's recommended upload encoding settings.

QUESTIONS

Frequently asked.

What bitrate should I export 1080p at?

YouTube recommends about 8 Mbps for 1080p30 (H.264, SDR) — treat that as the floor. Around 16 Mbps gives the platform's re-encode comfortable headroom, and busy, fast-moving footage earns more.

Does a higher bitrate always look better?

Only up to a point. Platforms re-encode everything down their own ladder, so gains shrink fast past the targets — a 100 Mbps 1080p export will not look better than 24 Mbps after upload.
