For a creator sending a prerecorded video to YouTube Live, a useful estimate is about 3.6 GB per hour at 720p30, 6.3 GB at 1080p30, and 7.65 GB at 1080p60. These are calculations from YouTube’s recommended H.264 ingestion bitrates, not measured totals or guaranteed consumption.
The figures estimate data sent by the creator’s connection. They do not describe how much a viewer downloads. Your actual carrier-accounted usage may differ, so use the bitrate calculation for planning and your carrier’s usage meter to check what happened on your own connection.
Which connection are we estimating?
A prerecorded source does not avoid live-stream upload. While the broadcast is running, your encoder or streaming service sends an encoded live feed to YouTube. For the creator-side estimate, the main inputs are the feed’s outgoing bitrate and the time it is sent.
That transfer is separate from uploading the original video file, if you upload it to a platform or service before the broadcast. It is also separate from every viewer’s playback. YouTube receives the incoming feed and transcodes it into output formats for viewers, who then use data on their own internet connections. Do not multiply the creator’s upload estimate by the audience size.
The distinction matters when you are deciding whether a mobile data allowance, fixed broadband connection or other link can support a long broadcast. A viewer watching your stream is receiving a different transfer from the one you send. If you are planning a playlist, the guide to streaming a pre-recorded video to YouTube Live from a cloud server explains the broader workflow; the numbers here focus on data volume rather than setup.
YouTube’s encoder guidance asks you to set resolution, frame rate and bitrate, and says it transcodes the incoming stream for playback across devices and networks. Its recommended encoder table is therefore a practical basis for a creator-side estimate, not a promise of what an Indian carrier will record. The calculation does not depend on an India-only bitrate. India is relevant when you compare that estimate with the account or usage meter from your own provider.
Convert Mbps into decimal GB per hour
A bitrate in Mbps means megabits sent each second. To estimate one hour of data, multiply by 3,600 seconds, convert bits to bytes by dividing by eight, then divide by 1,000 to express the result as decimal gigabytes:
Mbps × 3,600 ÷ 8 ÷ 1,000 = decimal GB per hour.
That simplifies to Mbps × 0.45. At 8 Mbps, for example, the calculation is 8 × 0.45 = 3.6 decimal GB per hour. This is arithmetic applied to a recommended bitrate, not a reading from a router or carrier bill.
The decimal unit is worth stating because storage tools and operating systems may also show binary units, often labelled GiB, while mobile plans and carrier meters can use their own presentation. If a screen shows a slightly different-looking figure, first check the unit, time period and whether it reports sent data, received data or both. Do not treat a small display difference as evidence that the bitrate calculation is wrong.
For a longer broadcast, multiply the hourly estimate by the number of hours. A continuous 24-hour run at a steady 8 Mbps would calculate to 86.4 decimal GB (3.6 × 24). That is still an estimate from the selected bitrate. It should not be entered as a guaranteed allowance requirement, because the real feed and network accounting can vary.
YouTube publishes different recommendations for H.264, AV1 and H.265. Keep codec columns separate when comparing settings: a bitrate listed for one codec should not silently be substituted into a calculation labelled for another. The figures below use the recommended H.264 values in YouTube’s live encoder settings and bitrate guidance. If you use another listed resolution or frame rate, multiply that codec’s own bitrate by 0.45 for the same kind of rough hourly estimate.
720p at 30 fps: about 3.6 GB per hour
YouTube’s recommended H.264 bitrate for 720p at 30 frames per second is 8 Mbps. The estimate is 8 × 0.45, or about 3.6 decimal GB per hour. Over a four-hour broadcast, the same calculation gives 14.4 GB before accounting differences between the configured bitrate and what the carrier counts.
This can be a reasonable starting point when your source material and audience do not need a higher resolution. It is not a universal instruction to choose 720p: text, fine details, motion and the kind of content you publish affect how the picture looks at a given setting. A devotional image with slow movement and a fast-moving local news clip may not tolerate the same compromise equally well.
If you are using OBS, check the output settings rather than assuming that a project’s canvas resolution tells you its upload bitrate. A separate OBS bitrate guide for a 24/7 4K nature ambience stream covers settings in a different resolution context; the same habit applies here: verify the actual outgoing value and match the calculation to it.
1080p at 30 fps: about 6.3 GB per hour
For 1080p at 30 frames per second, YouTube’s recommended H.264 ingestion bitrate is 14 Mbps. Applying the same formula gives 14 × 0.45 = 6.3 decimal GB per hour. A six-hour session would calculate to 37.8 GB at that steady rate.
Compared with 720p30 at 8 Mbps, the estimate is higher because the recommended bitrate is higher. You are trading a larger upload volume for a higher-resolution feed. Whether that is useful depends on the source and the viewing experience you want, not on the resolution label alone. If the original video is low resolution, sending it as 1080p does not create detail that is absent from the source.
For a channel that runs long sessions, an hourly difference accumulates. Before choosing a setting, compare the visual result using a representative part of your actual recording and check that the connection can sustain the upload without interruptions. The FFmpeg guide to keeping a YouTube stream running during power cuts in India discusses continuity risks; data planning and continuity are related but distinct concerns.
1080p at 60 fps: about 7.65 GB per hour
YouTube’s recommended H.264 bitrate for 1080p at 60 frames per second is 17 Mbps. The calculation is 17 × 0.45 = 7.65 decimal GB per hour. The estimate is higher than 1080p30 because the recommended outgoing bitrate is higher for this frame rate.
A higher frame rate can be useful when the material contains motion that benefits from it. A static devotional visual or a slow ambience loop may not need 60 frames per second; footage with faster movement may make the difference more apparent. The decision should be based on the source, the look you need and the data budget, rather than a general assumption that the largest setting is best.
Here is the comparison in one place:
| H.264 output setting | YouTube recommended bitrate | Estimated creator upload per hour |
|---|---|---|
| 720p at 30 fps | 8 Mbps | About 3.6 decimal GB |
| 1080p at 30 fps | 14 Mbps | About 6.3 decimal GB |
| 1080p at 60 fps | 17 Mbps | About 7.65 decimal GB |
The bitrate column reflects YouTube’s current encoder guidance available to this article’s research pass. The last column is derived arithmetic, not an observed total. If your software uses a different bitrate, use that configured value in the formula rather than selecting a row by resolution alone.
Why the carrier meter can differ
The calculation assumes a steady outgoing bitrate for the full hour. Real delivery may not behave like that. Your encoder or service may vary bitrate, audio is also part of the feed, and network protocols add traffic beyond the encoded video payload. A reconnect can send extra data or change how long the feed is active. Each can move the amount recorded by the network away from the simple estimate.
A setting marked 14 Mbps is not necessarily a constant 14 Mbps of traffic at every instant. Depending on how the encoder is configured, the bitrate can be a target, a limit or a value used within a variable-rate process. Image complexity can affect how much data is needed to represent a scene. The configured number is still a useful planning input, but it is not a meter reading.
India-facing carrier guidance can help with context, provided you do not confuse playback with upload. Jio lists broad video playback estimates of up to 0.3 GB/hour for Low, 0.7 for Medium, 1 for High, 3 for HD and 7 for Ultra HD, and notes that usage varies by app. Those are general quality-category figures, not YouTube Live creator-upload measurements. Jio also explains that higher playback resolution consumes more data in its video streaming guidance. They should not replace the bitrate calculation for your outgoing broadcast.
The same caution applies to bandwidth figures published for a different service. The National Informatics Centre’s webcast guidance refers to dedicated bandwidth in its own service scenario. That is not a universal YouTube bitrate recommendation and does not provide a guaranteed data total for your channel. Use a source only for the question it actually answers.
Check the encoder and your carrier’s meter
Start with the setting that is actually sending the stream. In OBS or another encoder, confirm the output resolution, frame rate, codec and bitrate profile. A project may have one canvas size and scale to another output size; the estimate should follow the outgoing stream. If you use a cloud or managed service, check its published output settings rather than assuming your uploaded source file’s size determines the live transfer.
Then record a baseline from your carrier’s app or account page before a test. Run a representative stream for a known period, note the meter again afterwards and compare the change with the calculation. Keep other devices and downloads in mind: a household meter may include more than the broadcast, and a phone hotspot may account for traffic from several connected devices. A one-hour test is useful evidence for your particular configuration, but it is not a guarantee for every future session.
For a long-running channel, repeat the check after changing resolution, frame rate, codec, bitrate, audio settings or streaming method. Write down the setting alongside the meter result. That gives you a local reference that is more useful than applying a generic playback estimate to a creator upload.
If the estimate is too large for the data you can allocate, the direct levers are to lower outgoing bitrate or resolution, choose a frame rate appropriate to the content, or shorten the broadcast. Check picture quality and stability after each change. Lowering a number without confirming the result can make the stream less usable, while keeping an unnecessarily high rate can consume more data without a visible benefit for your material.
If your present difficulty is keeping a recorded programme on air without leaving a computer running overnight, StreamNeo removes that specific need by taking an uploaded video and running it as a YouTube Live broadcast while your own computer is off. Data still depends on the chosen outgoing stream and duration, so a cloud workflow does not make the bitrate calculation irrelevant.

FAQ
How much data does a YouTube Live stream use in one hour?
For the creator sending the stream, the estimates from YouTube’s recommended H.264 bitrates are about 3.6 decimal GB at 720p30, 6.3 GB at 1080p30 and 7.65 GB at 1080p60. They are calculations, not measured totals or guarantees. Your encoder behaviour and carrier accounting can change the recorded amount.
Does this estimate include viewers watching the stream?
No. It estimates the creator’s outgoing live feed, not a viewer’s download. YouTube transcodes the incoming feed for playback, and each viewer uses data on their own connection. Audience size does not multiply the creator-side upload transfer.
Is the original video file upload included?
No. If you upload the prerecorded source file separately before the live broadcast, that is an additional transfer. The hourly figures cover sending the live feed while it is on air, not a prior file upload.
Why does my carrier meter show a different total?
The formula assumes a steady bitrate and converts it into decimal GB. Audio, protocol overhead, bitrate variation, reconnects and the carrier’s accounting can produce a different figure. Check the encoder settings and compare a representative test with your carrier’s usage meter for the closest estimate for your setup.
