For a pre-recorded file sent out as a YouTube Live broadcast at 720p50, use 8 Mbps for H.264 or 6 Mbps for AV1/H.265 as a practical starting point. These are not published 720p50 live recommendations: YouTube’s live table lists those bitrates for 720p30 and 720p60, so applying them to 50 fps is an inference.
If by “pre-recorded” you mean uploading a file as a normal YouTube video, use the separate upload guidance instead. The 7.5 Mbps figure for 720p SDR high-frame-rate uploads is not a YouTube Live ingest setting.
A practical 720p50 live bitrate starting point
Begin with the codec your encoder can reliably produce and YouTube’s live table supports. At 1280×720, the published table gives 8 Mbps for H.264 at 30 and 60 fps, and 6 Mbps for AV1/H.265 at those frame rates. For a 50 fps live feed, those numbers are useful starting points, not a precise value YouTube has published for that exact combination.
| Encoder codec | Starting video bitrate at 720p50 | What the published live table says |
|---|---|---|
| H.264 | 8 Mbps | 8 Mbps at 720p30 and 720p60; applying it at 50 fps is an inference |
| AV1 or H.265/HEVC | 6 Mbps | 6 Mbps at 720p30 and 720p60; applying it at 50 fps is an inference |
These are video bitrates, not the total amount of upload capacity to reserve. Audio and protocol overhead also use capacity, so your connection needs room beyond the video number. YouTube recommends maintaining 20% headroom above the total stream bitrate. The practical consequence is that a connection which only just reaches the video setting is not a comfortable choice for a long broadcast.
If your encoder does not support AV1 or H.265, do not try to force a codec selection solely to use the lower figure. H.264 is a straightforward, widely supported path. Use the codec you have tested and can maintain, then make sure the network can sustain the whole stream with headroom.
A file’s frame rate is not automatically a reason to change the live bitrate to a guessed in-between value. If the prepared source is 50 fps and the intended output is 50 fps, configure that rate in the encoder, then test the result. Avoid converting the source to 60 fps simply because the official live table happens to include a 60 fps row; that changes the output cadence and is not required by the table.
What YouTube’s live table actually lists
YouTube’s live encoder guidance provides recommended bitrates for resolution and frame-rate combinations that include 720p at 30 fps and 720p at 60 fps. It does not show a separate 720p50 row. The two relevant 720p values are the same across those listed frame rates: H.264 at 8 Mbps, and AV1/H.265 at 6 Mbps. Check the current YouTube Live encoder settings table before a production change, because platform guidance can be updated.
That absence matters when you write a setting into a checklist or share it with an operator. “YouTube recommends 8 Mbps for 720p50” overstates what the table says. A more accurate note is: “Starting with the YouTube-listed 720p30/60 H.264 value of 8 Mbps for 720p50; confirm in a test.” The equivalent wording for AV1/H.265 uses 6 Mbps.
The figures refer to video encoding. The setup guidance separately describes audio codecs and settings. For RTMP/RTMPS, YouTube allows AAC or MP3, and notes that 5.1 surround support is available with AAC. Keep audio settings separate from the video bitrate field rather than interpreting 8 Mbps as an all-in total.
The live table also names operational encoder settings, not just bitrate. YouTube lists constant bitrate (CBR), a keyframe interval of two seconds, and says not to exceed four seconds. It recommends RTMPS for the connection. Set these consistently with the supported options in your encoder instead of treating bitrate as the only control that matters.
For a practical explanation of encoder trade-offs on a pre-rendered loop, the VLC settings for streaming to YouTube Live offer a relevant comparison point. The resolution there differs from this case, but the useful principle is the same: settings should correspond to the outgoing stream, not simply to the source file’s properties.
Why 50 fps is an inference, not an exact recommendation
A 50 fps stream sits between the published 30 and 60 fps entries in the live table, but the table does not state that its values are a universal formula for all intermediate frame rates. Using the nearest published 720p values for a 50 fps starting point is reasonable because both listed frame-rate entries agree at each codec. Still, YouTube has not published the exact 720p50 live combination in the cited guidance.
This distinction is not merely editorial. An official recommendation is what YouTube explicitly provides; an inference is an operating choice made from nearby official values. In a configuration sheet, label it as an inferred starting point, retain the source link, and avoid implying that YouTube has tested or endorsed that exact row. If YouTube adds a 50 fps row later, prefer the current table.
The same caution applies to the difference between codecs. The 6 Mbps entry for AV1/H.265 does not mean every encoder, source, or viewing condition will produce an identical result to H.264 at 8 Mbps. The codec choice depends on whether your software can encode it reliably and whether your viewers’ devices can play the resulting stream. If compatibility is uncertain, testing is more useful than assuming the lower number is automatically better.
The source content also matters in a practical way. A static devotional image with a slow ticker does not stress the picture in the same way as fast camera movement, a dance performance, or a busy news loop. Yet the source’s stillness does not turn the bitrate table into a different official recommendation. Use the values as a starting point and judge the encoded preview for blockiness, motion clarity, and audio-video synchronisation.
Keep live ingest separate from file upload
“Pre-recorded” describes the material, not necessarily the delivery method. If you upload a video through YouTube Studio as a normal video, you are using YouTube’s upload path. If an encoder reads a prepared file and sends it to a live event, you are using YouTube Live ingest. The file can be identical; the recommendation you consult changes with the workflow.
For uploads, YouTube’s separate recommended upload encoding settings specify 7.5 Mbps for 720p SDR high-frame-rate video, where high frame rate includes 48, 50, or 60 fps. That number belongs to uploading a video file. Do not copy it into the live encoder because the file happens to be 50 fps, and do not describe it as a 720p50 live bitrate.
A quick way to avoid the mix-up is to ask what happens after you press the button. If YouTube receives a completed file that viewers can watch on demand, consult upload encoding guidance. If your encoder maintains a live connection to an event and the video appears as a broadcast, consult live encoder guidance. A pre-rendered playlist streamed continuously still counts as live ingest while it is being transmitted as a live event.
This distinction also helps when diagnosing quality. A file that looks clean on your computer may be encoded again during the live output. Check the Live Control Room preview of the actual broadcast path rather than relying only on the local source file. For a devotional workflow, the prerecorded kirtan test guide provides a useful model for checking a prepared programme before making it public.
Set the encoder and test a sample
Set the output to 1280×720 at 50 fps if that is the prepared source and the output you intend viewers to receive. Choose the codec, then enter the practical starting bitrate from the table above. Select CBR, set a two-second keyframe interval, and use RTMPS where your encoder provides that option. The exact labels and screens vary by encoder, so verify the values in its output settings rather than assuming the project or source-file settings control the live feed.
Test a representative segment before committing to the full broadcast. Include the same sort of movement and audio you expect in the real programme. For a bhajan loop, that might mean a singer moving in frame, a scrolling title, and the actual music mix; for local news, use a segment with camera movement and graphics. A static splash screen alone is a poor test of moving content.
Watch the preview for visible softness, block artefacts around motion, dropped or repeated-looking frames, and audio that drifts out of sync. If the picture breaks up, first check whether the connection is struggling or another device is using upload capacity. Do not increase the bitrate as a reflex: a higher video setting asks the connection to carry more, which can worsen instability. If the connection is solid but quality is insufficient, test encoder settings and a short segment again.
YouTube’s setup advice says to arrange the encoder at least two hours before the event and to start it at least 15 minutes before the event. Those are useful preflight timings rather than bitrate rules. During that window, confirm the incoming signal in the Live Control Room and verify that the intended video and audio are actually reaching YouTube. For a persistent loop, the checklist in how to run a 24/7 YouTube stream with PRISM Live Studio can help you think through the wider operating routine, while the encoding values here remain applicable to the chosen output.
Plan bandwidth around the whole stream
YouTube recommends upload capacity with 20% headroom above the total bitrate. Apply that allowance to the combined live stream, not only the video field. If your video is set to 8 Mbps, account for audio and overhead before applying the margin; do not assume an 8 Mbps connection is enough just because it matches the video setting. The 6 Mbps codec path likewise needs room for audio and overhead.
Measure upload capacity, not just download capacity. A broadband plan may show a strong download figure while its upload performance is more limited. YouTube’s streaming tips on bandwidth and connection reliability advise testing upload capacity and accounting for other use on the same network. A cloud backup, video call, or another person uploading large files can reduce the capacity available to your broadcast.
Run the test under conditions that resemble the broadcast, including the same connection and other network use where possible. If a speed test shows only a narrow margin, reduce competing traffic, consider a lower-rate tested output, or choose a connection with more available upload capacity. There is no single speed-test result that guarantees a stable stream, because capacity can vary and a speed test is a snapshot.
A wired connection can be a practical choice when it is available, but it is not a guarantee of adequate capacity. YouTube recommends a reliable connection and suggests testing network failover as part of encoder preparation. If you rely on Wi-Fi or mobile broadband, observe the actual Live Control Room health indicators during a representative test rather than making assumptions based on signal bars alone.
Monitor stream health during a long broadcast
A bitrate choice is only one part of a live channel that has to keep running. Monitor the Live Control Room’s stream health messages and preview. If the incoming stream reports instability, look at upload capacity, encoder load, and the local network before changing several settings at once. Change one factor, then observe whether the next test improves.
Pre-recorded content can make a stream look deceptively settled: the video file is finished, but the live delivery path is still active. Playback can stop, the encoder can lose its connection, or the source can loop incorrectly. YouTube’s live-streaming tips recommend testing the encoder and checking the stream before the event; for a continuous channel, make that part of a routine check rather than something done only once at launch.
Keep a short note of the settings that worked, the codec, the observed health messages, and the type of source segment used in the test. If you later change the source, encoder, connection or output frame rate, repeat the test. That record makes it easier to distinguish a bitrate problem from an unrelated change.
When the specific pain is keeping a prepared file broadcasting without leaving your own computer running all night, StreamNeo can remove that local-computer burden: you upload the video once, provide your YouTube stream key, and the broadcast continues with monitoring and automatic restarts if it drops. It is a YouTube-only route; you should still prepare and check the file, channel and live settings.

FAQ
Is 8 Mbps YouTube’s exact 720p50 live recommendation?
No. YouTube’s live table lists 8 Mbps for 720p30 and 720p60 H.264, but not 720p50. Using 8 Mbps for 720p50 H.264 is a practical inference from the listed values, not an exact published recommendation.
Can I use 6 Mbps at 720p50?
It is a reasonable starting point if your live encoder uses AV1 or H.265/HEVC, because YouTube lists 6 Mbps for both 720p30 and 720p60 with those codecs. The 50 fps application remains an inference, and the encoder and viewers must support the codec reliably.
Is 7.5 Mbps the right setting for a 720p50 live stream?
Not on the basis of YouTube’s upload table. The 7.5 Mbps figure is for 720p SDR high-frame-rate video uploads, including 50 fps; live ingest uses the separate live encoder guidance.
What should I change if the stream becomes unhealthy?
Check the Live Control Room messages and your available upload capacity first, including other use on the network. YouTube recommends 20% headroom over the total stream bitrate, so a connection with little spare capacity may need less competing traffic or a lower tested output setting.
