YouTube recommends a 20% margin for general streaming; if you send a backup stream or stream to several destinations, include those bitrates too.
Recommended YouTube Live bitrates
YouTube’s live encoder recommendations depend on the video codec, resolution, and frame rate. The table below reproduces the recommendations on YouTube’s live encoder settings page surfaced on October 3, 2026. They are recommendations, not guarantees of stream quality or network performance.
| Incoming resolution and frame rate | AV1 or H.265 video | H.264 video |
|---|---|---|
| 2160p (4K), 60 fps | 35 Mbps | 50 Mbps |
| 2160p (4K), 30 fps | 30 Mbps | 42 Mbps |
| 1440p, 60 fps | 24 Mbps | 34 Mbps |
| 1440p, 30 fps | 15 Mbps | 21 Mbps |
| 1080p, 60 fps | 12 Mbps | 17 Mbps |
| 1080p, 30 fps | 10 Mbps | 14 Mbps |
| 720p, 60 fps | 6 Mbps | 8 Mbps |
| 720p, 30 fps | 6 Mbps | 8 Mbps |
| 480p, 30 fps | 3 Mbps | 4 Mbps |
| 360p, 30 fps | 3 Mbps | 4 Mbps |
These are video recommendations. YouTube’s page also gives lower minimum settings; do not mistake a minimum for its recommended target. For example, at 1080p60, the recommended target is 12 Mbps for AV1 or H.265 and 17 Mbps for H.264. At 720p30 or 720p60, it is 6 Mbps for AV1 or H.265 and 8 Mbps for H.264. Check YouTube’s live encoder settings for the current table before configuring a stream, since recommendations can change.
How much upload speed do you need?
Your internet connection’s outbound upload capacity must support the outgoing stream traffic. A download-speed result does not establish this: download speed is often higher, and a shared connection may leave less upload bandwidth available while other devices are active. YouTube’s general network guidance recommends leaving a 20% margin; that buffer is advice, not a guarantee against ISP variation or congestion. See YouTube’s network tips.

One stream
Start with the selected video bitrate and include audio and any other outgoing stream traffic in your planning. Apply YouTube’s recommended 20% margin to the total. As a simple illustration, a 10 Mbps stream target with a 20% margin calls for about 12 Mbps of available upload capacity. That is arithmetic based on YouTube’s guidance, not a tested result or promise that a connection will remain stable.
Primary and backup streams
If your encoder sends both a primary and backup stream, count both configured bitrates before adding headroom. For example, 10 Mbps primary plus 10 Mbps backup equals 20 Mbps of stream traffic; the simple 20%-margin calculation is about 24 Mbps available upload. This example is arithmetic, not a measured performance outcome.

Streaming to multiple platforms
For simulstreaming, add the target bitrates for all destinations. YouTube’s separate multi-destination guidance recommends upload capacity 1.5 to 2 times that combined total, particularly on shared connections. Its example is 6 Mbps plus 4 Mbps of stream targets, for which it suggests aiming for 15–20 Mbps upload. This more conservative guidance is specific to multi-destination streaming; do not confuse it with the general 20% margin. See YouTube’s simulstreaming guidance.
Configure your encoder
Use YouTube’s current settings for the exact codec, resolution, and frame rate you plan to send. Its general encoder guidance recommends the following:

Audio settings are separate from the video bitrate recommendations in the table. For details and any changes to supported settings, consult the YouTube encoder settings page and streaming protocol guidance.
Preflight: test the actual stream conditions
- Measure upload capacity. Check outbound upload speed, not only download speed. Test under conditions similar to the planned broadcast, including typical network use by other devices.
- Set the encoder target. Match the bitrate to the YouTube table’s codec, resolution, and frame-rate row, and budget for audio and any additional stream outputs.
- Run a representative test. Include audio and movement similar to the live content; a static screen or silent test may not represent the stream’s actual demands.
- Check YouTube’s stream health. During the test and live broadcast, monitor stream health and read any messages shown in YouTube’s interface.
YouTube recommends testing before starting a public stream. A speed test is only a snapshot of available capacity; it cannot ensure the connection will remain uncongested. See YouTube’s streaming tips.

Is 10 Mbps upload enough for 1080p?
It depends on the frame rate, codec, and how much upload capacity is actually available. For 1080p30, YouTube recommends 10 Mbps with AV1 or H.265 and 14 Mbps with H.264; for 1080p60, it recommends 12 Mbps with AV1 or H.265 and 17 Mbps with H.264. Those figures are video bitrate targets, not the total internet plan speed to shop for. A 10 Mbps upload connection cannot provide the recommended 20% margin for a 10 Mbps video target, even before accounting for audio or competing network use.
Common bitrate and upload problems
- Stream health reports connection trouble: compare the full outgoing traffic against available upload capacity, including backup streams, and retest when the network is under typical load.
- Download test looks fast, but the stream struggles: check outbound upload capacity specifically; download speed does not show how much data can be sent reliably.
- Bitrate seems adequate on paper, but performance varies: shared-network activity or connectivity disruption may reduce available bandwidth. Retest in representative conditions and monitor YouTube’s stream-health messages.
- Encoder settings do not match the selected recommendation: confirm codec, resolution, and frame rate, then use the corresponding YouTube row. Keep CBR enabled and set a 2-second keyframe interval, no more than 4 seconds.
- Multi-destination or backup output was omitted from the calculation: add the targets together before planning capacity; use YouTube’s 1.5–2-times guidance for simulstreaming.
