YouTube’s official live encoder table does not give an exact bitrate recommendation for 1080p at 50 fps. It lists 1080p at 30 and 60 fps instead, so use those rows as reference points for a test—not as a basis for claiming YouTube recommends an interpolated 50 fps value.
Your working setting depends on the video codec, encoder behaviour and the upload connection available to the stream. Test with the intended loop and audio, then watch YouTube Live Control Room for stream health messages before relying on the setting overnight.
Is there an official YouTube Live bitrate for 1080p50?
No. The YouTube live encoder settings page lists 1080p at 30 fps and 1080p at 60 fps, but does not include a 50 fps row. That is the important distinction when answering a search for “YouTube live stream bitrate for 1080p 50fps”: any exact 50 fps figure presented as YouTube’s published recommendation would go beyond the table.
The missing row does not mean that a 50 fps stream cannot be sent. YouTube’s general live encoder guidance lists support for frame rates up to 60 fps, while its bitrate recommendations are presented according to codec, resolution and frame rate. A supported frame rate and a published bitrate recommendation are different things. You can configure an encoder for 50 fps, but you still need to determine an appropriate bitrate through a representative test.
A video loop does not create a separate row in YouTube’s table either. A quiet devotional image, a lofi animation and a local news loop may place different demands on an encoder because their visual movement and detail differ. But the source material being a loop does not justify replacing YouTube’s missing 1080p50 value with a made-up official number.
The practical answer is to identify the codec you will use, compare YouTube’s adjacent 30 and 60 fps guidance for that codec, and test the actual stream. If the broadcast must run while nobody is available to notice a problem, the test should include the same sort of motion and sound as the scheduled channel, not just a static screen that is easier to encode.
What YouTube lists for 1080p30 and 1080p60
The table below reproduces the listed minimum and recommended values for 1080p at the frame rates nearest to 50 fps. They are reference points for their labelled rows, not a 1080p50 prescription.
| YouTube live table row | AV1 and H.265 minimum | AV1 and H.265 recommended | H.264 minimum | H.264 recommended |
|---|---|---|---|---|
| 1080p at 30 fps | 4 Mbps | 10 Mbps | 5 Mbps | 14 Mbps |
| 1080p at 60 fps | 4 Mbps | 12 Mbps | 6 Mbps | 17 Mbps |
Codec matters: at the same listed resolution and frame rate, YouTube’s recommended values differ between H.264 and AV1/H.265. If your encoder is set to H.264, use the H.264 columns when making your comparison. If it is set to AV1 or H.265, use the corresponding columns. Do not choose a column based only on what the computer or streaming application appears capable of; confirm the codec actually being sent to YouTube.
The recommended figures are not the minimum figures. A minimum is not a promise that a particular loop will look acceptable at that rate, nor does the table say that every connection can sustain the recommended value. You still need to judge picture quality and stream stability together. A clear picture with repeated health warnings is not a sound setting for an always-on channel; neither is a stable-looking feed whose detail has visibly degraded.
The table makes two useful comparisons possible without filling in its gap. First, it shows that the codec changes the recommended rate. Second, it shows that the listed recommendation rises between 30 and 60 fps for each codec grouping. Those patterns can inform your test choices, but the page does not state a formula for converting them into a 50 fps value.
Why upload guidance does not fill the live-table gap
YouTube has separate documentation for live ingest and prerecorded video uploads. The upload encoding settings page covers a file uploaded for processing and playback; it is not a live encoder bitrate table. Its guidance may be relevant if you are preparing a finished video file, but it cannot be substituted for a live-stream recommendation.
This difference matters for a loop. You may create or export a video file at 50 fps and then send it continuously as a live broadcast. The file’s export settings describe the encoded source. The live encoder settings describe what your broadcast software or service sends as the live feed. Depending on your setup, the source may be decoded and encoded again for live delivery, so a file’s upload bitrate is not necessarily the bitrate used for the stream.
The upload page can confirm that high frame rates are used for prerecorded video, but that does not add a 1080p50 row to live guidance. Treat the two pages as answering different questions: one addresses the encoding of uploads, and the other addresses live ingestion. If you are configuring OBS, FFmpeg or another encoder for a live loop, rely on the live documentation for the settings it actually covers, then test the omitted frame-rate case yourself.
For a broader workflow around continuously sending a folder of files, see this guide to streaming a folder of videos to YouTube Live in a loop. It is useful to keep the source-file workflow distinct from the live encoder settings: making a loop play repeatedly does not settle the bitrate question.
Choose a test rate for your encoder
Start by writing down three things: output resolution, output frame rate and output codec. Set the intended stream to 1080p and 50 fps, then confirm whether the encoder is sending H.264, H.265 or AV1. Compare the 30 and 60 fps rows for that codec. This narrows the relevant official references without pretending either one is the missing 50 fps recommendation.
A sensible test compares candidate settings, rather than treating a calculated midpoint as an official answer. You might begin by testing a rate informed by the lower adjacent recommendation, then test a higher candidate informed by the upper row if the connection and encoder can sustain it. The suitable choice is the one that produces acceptable picture quality and stable ingest under representative conditions. The table does not prescribe a particular intermediate rate, and your test need not assume that frame rate and bitrate scale linearly.
Use a section of the loop that represents the demanding parts of the programme. A still image with a devotional track is not a meaningful test for a sequence with moving lyrics, camera pans or animated backgrounds. Conversely, a brief action-heavy clip may not represent a mostly static lofi station. Include the actual audio, transitions and overlays that will be present during the broadcast, and check whether they affect the encoder load or stream quality.
YouTube’s live guidance recommends constant bitrate (CBR) and a two-second keyframe interval, with a maximum interval of four seconds. These are separate encoder settings from the bitrate itself, but they should be checked as part of the same preflight. The guidance also identifies RTMP and RTMPS as protocols and recommends RTMPS. Confirm the configuration your software actually applies rather than assuming a preset has selected every recommended value.
If you change codec, resolution, frame rate, encoder preset or the content itself, regard the previous test as limited evidence. For example, a rate that worked for an H.264 test does not establish an AV1 setting, and an upload connection that was idle during a short test may behave differently when other devices are active. Keep notes on what you tested and what Live Control Room reported; that gives you a repeatable baseline instead of relying on memory.
If you want to keep a test separate from the production channel, check YouTube’s official test and troubleshoot guidance for current options. The article on saving OBS settings before updating a 24/7 stream PC is also relevant if you use OBS: preserving a known configuration makes it easier to identify whether a later bitrate change actually improved the stream.
Check connection capacity and Live Control Room
The encoder can only send reliably if the available upload connection can sustain the stream. A speed test is a useful starting point, but its result is a measurement at one moment, not a guarantee about the entire night. Other uploads, cloud backups, Wi-Fi interference or household use can reduce the capacity available to the stream. Test under conditions that resemble the planned broadcast, including the ordinary activity on the same connection.
YouTube does not give a fixed upload-headroom percentage in the cited live guidance. Avoid converting a personal rule of thumb into an official requirement. Instead, leave enough practical capacity that the test remains stable when the connection is being used normally, and reduce competing uploads during a critical broadcast if they interfere. If the link struggles, lowering the stream bitrate or choosing a less demanding output may be more useful than insisting on the highest listed recommendation.
During a preflight, send video with similar movement and audio to the planned programme. Check both the encoder’s own status and YouTube Live Control Room. Look for connection warnings, dropped frames or other stream health messages, and see whether the picture and sound remain acceptable over time. YouTube specifically advises testing before a live event and monitoring stream health and messages during it; a stream that appears connected is not by itself proof that the received video is healthy.
For a 24/7 channel, a test should cover more than the moment when you press Go Live. Check what happens when the loop changes scenes or reaches a file boundary, when audio continues across a transition, and when the network is under normal load. If the channel operates from a home connection, repeat the check at a time when other people would ordinarily use it. Record the chosen settings and what the control room showed so that a later fault can be compared against a known baseline.
A bitrate test also cannot establish that the stream will never disconnect. It only provides evidence about the tested encoder, content and connection. If you are diagnosing repeated drops, use a separate troubleshooting process, such as this guide to an OBS YouTube 24/7 stream that keeps disconnecting, rather than raising bitrate automatically. Increasing the rate can worsen a connection problem.
Avoid treating adjacent values as a rule
It can be tempting to calculate a midpoint between the 30 fps and 60 fps recommendations and label it “the 50 fps bitrate”. That calculation would be yours, not YouTube’s. The table gives values for specified frame-rate rows; it does not say that bitrate rises in a straight line between them or that an interpolated value is optimal for every codec and source.
Even an internally consistent calculation misses real differences. Two loops at 1080p50 can contain very different amounts of movement and detail. The encoder may also behave differently depending on codec and its configuration. Connection conditions vary as well. For those reasons, the adjacent values are useful guardrails for choosing tests, but they cannot replace observing the resulting stream.
Do not assume a loop requires less bitrate simply because its duration repeats. A steady image may be easier for an encoder than a moving scene, but the official table does not give a loop-specific adjustment. If your content has a static background for much of the time, test it as it will actually appear; if it includes scrolling lyrics, animated visualisers or scene changes, include those too. Avoid reducing the setting based on the word “loop” alone.
When the initial test shows unstable ingest, do not jump to a more complex encoder configuration before checking basics: whether the selected codec and frame rate match the intended output, whether the connection is in use elsewhere, and whether the control room identifies a stream health issue. When the stream is stable but the picture is poor, compare the actual content at the tested rates and codec rather than relying on a number calculated from the table. The next change should address the observed problem.
For some operators, the harder problem is not choosing a number but keeping a broadcast running when the home computer is switched off or a local process needs attention. StreamNeo can remove that specific burden by running an uploaded video as a YouTube live stream without requiring your computer to stay on; you still need to check the video, stream key and resulting stream health. It is YouTube-only, so it is not a fit if you need to broadcast the same feed to another platform.

FAQ
Does YouTube publish an exact bitrate for 1080p at 50 fps?
No. Its live encoder table lists 1080p at 30 fps and 60 fps, but not 50 fps. Use the adjacent entries to plan a test, and do not label an interpolated value as YouTube’s recommendation.
Can I use the 1080p high-frame-rate upload bitrate for a live loop?
Not as a live-stream recommendation. YouTube’s upload encoding guidance concerns prerecorded files, while its live encoder page covers live ingest. Keep those settings separate when configuring a loop that is broadcast continuously.
Should I use the 30 fps or 60 fps row for a 50 fps stream?
Neither row is an exact match, and YouTube does not say to select one as the official 50 fps value. Compare the row for your codec, use the figures to frame a representative test, and judge the result in Live Control Room as well as on the encoder.
Does a mostly static loop need less bitrate?
A still or slowly changing picture may be easier to encode than footage with frequent motion, but YouTube does not publish a loop-specific bitrate adjustment. Test the actual mix of still scenes, movement, transitions and audio that your channel will send, then prioritise stable ingest and acceptable picture quality.
