Question 1

What is video bitrate?

Accepted Answer

The amount of data the video uses per second of playback, measured in bits per second (bps). Higher bitrate generally means higher quality.

Question 2

How do I pick the right bitrate?

Accepted Answer

Use the calculator: enter resolution, framerate, and codec, and we return YouTube/Twitch-recommended ranges plus a quality slider.

Question 3

YouTube recommended bitrates?

Accepted Answer

1080p30: 8 Mbps. 1080p60: 12 Mbps. 4K30: 35-45 Mbps. 4K60: 53-68 Mbps. HDR adds ~25%.

Question 4

Twitch streaming bitrates?

Accepted Answer

Twitch caps at 6 Mbps for non-Partners. Use 4500-6000 Kbps for 1080p60, 3500-5000 Kbps for 720p60.

Question 5

H.264 vs H.265 vs AV1?

Accepted Answer

H.265 (HEVC) and AV1 deliver the same quality at ~30-50% lower bitrate than H.264, but encoding time and player support differ. AV1 is best for archival, H.264 for compatibility.

Question 6

CBR vs VBR?

Accepted Answer

CBR (constant) holds bitrate steady — best for live streaming. VBR (variable) saves bandwidth on simple scenes — best for upload/archive.

Question 7

How does framerate affect bitrate?

Accepted Answer

Doubling the framerate (30 → 60) typically requires ~50% more bitrate to maintain quality, since there is more motion per second.

Question 8

Can I export ffmpeg flags?

Accepted Answer

Yes — the tool produces a copy-paste ffmpeg command line for your selected codec, bitrate, and container.
