For a 24/7 YouTube channel, the data you send is mainly determined by the live stream’s outgoing bitrate, not by how large the MP4 file is on your computer. Shrinking a stored MP4 can save storage or transfer data, but it will not by itself reduce a separately configured live feed.
First work out whether your concern is the size of a source file or the data used by the continuous broadcast. If it is the latter, adjust and test the encoder’s output bitrate, and consider resolution or frame rate only if the picture still serves the channel.
Find the source of the data use
There are two different jobs that are easy to confuse. One is moving or keeping a video file: you may download an MP4, copy it to a drive, or upload it to a service. The other is sending a live broadcast to YouTube, which means the encoder continuously uploads an audio-and-video signal while the stream is running.
If your channel loops a local devotional video, a lofi visual, a shop promotion, or a news bulletin, the MP4 may be the material being played. But the live encoder still produces a stream at its configured rate. A 500 MB source can feed a live stream configured at a particular bitrate, just as a much larger file can. File size and live output are related only if your workflow explicitly changes the encoding settings that produce the broadcast.
Check where the data is going. If a mobile hotspot or broadband provider reports usage during a live session, the stream’s outgoing traffic is a likely part of it; other devices, software updates, cloud backups and viewing activity may also count. If the issue is an MP4 that takes too long to copy or upload before the channel starts, re-encoding that file may be useful. It is a separate remedy from lowering the broadcast’s ongoing data use.
A practical first check is to note the encoder’s total output bitrate, including audio, and the time the stream runs. Then compare that with the plan’s usable data allowance and its terms after any cap. Do not assume the number printed beside a plan is all available for this one job: household use and the provider’s fair-use or throttling terms matter too. If you are configuring a local loop in OBS, this guide to lightweight streaming software for older PCs may help distinguish playback workload from broadcast settings.
Bitrate is what accumulates during a live broadcast
Bitrate is the amount of encoded information sent each second. A steady 1 Mbps stream transmits about 10.8 GB over a day and about 324 GB over 30 days, using decimal units. These are arithmetic estimates: 1 megabit per second multiplied by the number of seconds, then divided by eight bits per byte.
The estimate grows in direct proportion to bitrate and runtime. At 3 Mbps, the simple calculation is about 32.4 GB in a day or 972 GB over 30 days. At 0.5 Mbps, it is about 5.4 GB a day or 162 GB over 30 days. These figures approximate a continuous upload; they are not a promise that a particular Indian data plan will cover it.
The real count may be higher because of protocol overhead, reconnects, and other traffic using the same connection. How a provider counts data can also differ. If your figure is for video bitrate alone, add audio bitrate before estimating; if it is the encoder’s total stream bitrate, audio is already included. Leave room for usage beyond the stream rather than spending the entire allowance on the calculation.
YouTube’s live encoder settings guidance lists recommendations by codec, resolution and frame rate. As listed in that guidance when checked on 3 October 2026, its H.264 ranges include 3–8 Mbps for 720p at 30 frames per second and 0.4–4 Mbps for 480p at 30 frames per second. Those are platform recommendations, not a guarantee of a particular picture or a fit with your plan. The same page gives different ranges for AV1 and H.265, so check the current table for your selected codec rather than treating one figure as universal.
The calculation is most useful before settling on a setting: take the total stream bitrate, estimate the monthly upload, and compare it with data left after ordinary use. If that comparison does not work, consider a lower live output setting or a connection and plan with suitable sustained upload and allowance. Neither compressing the stored MP4 nor buying a larger storage drive changes the bitrate the encoder sends.
Lower the outgoing bitrate with a test
If the objective is to use less data while live, lower the encoder’s outgoing bitrate cautiously. YouTube says that the total bitrate being streamed cannot exceed the available upload bandwidth; its streaming tips also advise checking the network and monitoring audio and video quality. A short speed test gives a snapshot, not proof that a connection will sustain a setting overnight or through the week.
Choose the lowest setting that preserves what viewers need to see. For a mostly static image with a song title and devotional artwork, less bitrate may be acceptable than for a moving camera, animated lyrics or scrolling local news ticker. A small business showing changing menu details or text should check legibility, not just whether the image appears smooth. Lower bitrate makes each second cheaper in data, but can make motion, fine detail, gradients and text look worse.
Use the total bitrate, not only a video field, for your data estimate. Audio consumes part of the outgoing stream too. YouTube’s live settings table recommends an audio bitrate for stereo, but a channel should use settings suited to its content and current platform guidance. For a bhajan station, listen for distortion and abrupt changes in level after adjusting. For speech or local news, make sure the voice remains clear over any background music.
Change one setting at a time. If you lower video bitrate and resolution together, and then the picture softens, you will not know which change caused it. Record the old settings, test a lower bitrate with the same source, and inspect a representative section containing the most demanding material. If the result is not acceptable, return to the earlier setting or test a different resolution rather than blindly pushing the number down.
Your connection needs headroom for variation; YouTube does not set a universal percentage that works for every connection. If upload capacity fluctuates, a configured total stream rate very close to the apparent peak can lead to interruptions or degraded stream health. If you cannot sustain the upload consistently, use a lower tested setting or investigate the connection, instead of trusting a brief peak reading.
Reduce resolution or frame rate only where it helps
Resolution is the image dimensions, while frame rate is how many frames are sent per second. Lowering either may allow a lower bitrate while keeping an acceptable picture, but these changes affect what viewers see. A static shrine image, an ambient night scene or a fixed shop display may not need the same detail or motion as a camera following activity or a bulletin with fast-moving text.
YouTube’s published live ranges show that recommended rates vary by resolution, frame rate and codec. For example, at 30 fps, the H.264 guidance has a lower range for 480p than for 720p. This is a useful comparison, not evidence that every channel should use 480p or that a lower setting will look good for your content. YouTube also lists different guidance for other codecs. Confirm the current requirements before changing your encoder configuration.
Test text at the size viewers will actually watch. A channel logo may remain recognisable at a smaller resolution, while a ticker or lyrics can become difficult to read. Similarly, a still image can look satisfactory at a lower frame rate, but a video of dancing, traffic or a camera pan may appear less natural. Consider what the channel promises: reducing detail may save data, but obscuring information or making movement unpleasant is not a useful trade.
If you are running from a computer, adjust the live output settings in the encoder you use; do not assume that reducing the dimensions of the local MP4 changes those settings automatically. An upload workflow and a live workflow can use separate recommendations. YouTube’s upload encoding guidance covers uploaded files, not a substitute for checking live ingest settings.
Re-encode an MP4 for storage or transfer
An MP4 is a container holding encoded video and audio streams. Re-encoding changes those streams, potentially reducing the file size by lowering quality, bitrate, resolution or frame rate. The amount saved depends on the original file and the choices made; there is no reliable universal setting that guarantees a particular new size.
This is useful if an MP4 is cumbersome to archive, copy between devices, or transfer before a scheduled broadcast. It is not a way to reduce a separately configured encoder’s ongoing live output. If the file is already compressed and your broadcast encoder is set to a fixed total bitrate, re-encoding the source may save disk space while the broadcast continues to send at that configured rate.
If you do re-encode, keep the original and make a short representative sample first. Include the most detailed artwork, moving scenes, small text and the kind of audio used in the full programme. Inspect the result on a phone as well as a larger screen where possible, and listen with headphones or the normal playback setup. A file that looks fine on a desktop may make small lettering hard to read on a phone.
Repeated lossy re-encoding can discard more detail each time. Work from the best original you have, not from a previously compressed copy if avoidable. If you use FFmpeg, its official codec documentation describes options such as CRF, which targets quality, and presets, which trade encoding speed against compression. Those controls do not predict an exact file size for every source. Test and compare the output rather than relying on a CRF value as a size promise.
YouTube’s upload guidance recommends MP4 and H.264 for video, with supported audio options described on that page. It also discusses placing the MP4’s moov atom at the front for Fast Start. That can help progressive playback of an uploaded file; it is not a method for reducing a live stream’s outgoing bitrate. Keep upload-oriented requirements separate from your live encoder configuration.
Test picture quality and stream health
A setting is only useful if both the picture and the broadcast remain acceptable. Run a test with the real material: include a quiet section, the busiest motion, the smallest text, and the normal audio. Check playback on a separate viewer connection rather than relying only on the encoder preview, which may not expose problems a viewer experiences.
Monitor YouTube Live Control Room’s stream health while the test is running. Watch for warnings, dropped or unstable output, and audio or video issues. The test should last long enough to reveal changes in the connection, not merely show that the stream begins. For an always-on channel, an overnight or otherwise representative run is more informative than a quick check at a convenient moment, though no single test proves future performance.
Compare the result against the purpose of the channel. For lofi, the image may be secondary but audio continuity matters. For local news, text must remain legible. For a restaurant promotion, offers and opening details should be readable. For a devotional loop, the visual can be simple, but do not let compression make the image distracting or the audio tiring.
If the stream drops, separate the possible causes: the total bitrate may be too high for sustained upload; another device may be consuming the connection; or the encoder or network may be unstable. Lowering the source MP4’s file size does not diagnose these conditions. Keep a note of settings, observed stream health and the test content so that each adjustment has a clear comparison point. The advice on keeping a relaxation stream playing overnight is also relevant when checking a long-running loop, while this troubleshooting guide for a lofi stream showing “No data” covers a different symptom that can appear during setup.
For a computer-based workflow, the machine also needs to remain available and the connection needs to stay usable. If your problem is that a home computer must remain switched on, StreamNeo can remove that specific burden by running an uploaded file as a YouTube live stream without your computer staying on. It does not change the need to choose a suitable stream setting or check your data allowance, and it is for YouTube rather than other platforms.

FAQ
Will compressing my MP4 reduce data use during a 24/7 live stream?
Not by itself. The live encoder continuously sends its configured output, so its total bitrate is the main control for stream data use. Re-encoding a source file helps with file storage or transfer unless it also changes the settings that determine the live output.
How much data does a 24/7 stream use?
Estimate from the total outgoing bitrate and runtime. As arithmetic, 1 Mbps continuously is about 10.8 GB per day or 324 GB over 30 days in decimal units; actual use can differ because of overhead, other traffic, reconnects and provider counting. Compare the estimate with your plan’s usable allowance rather than assuming a particular plan is enough.
What bitrate should I choose for a limited data plan?
There is no setting that fits every plan, connection or picture. Check YouTube’s current live recommendations for your codec and output, estimate data from the total bitrate, and test a lower setting with representative content. Confirm both playback quality and stream health before relying on it for a long run.
Does lowering resolution always make a stream better for a limited connection?
Lower resolution can allow a lower bitrate, but it can also make small text and fine detail harder to see. Lower frame rate may suit a static scene better than fast movement. Test the actual material on a viewer device and choose the lowest setting that still serves the channel.
