Cloud VPS 4 is a reasonable starting point for one modest, software-encoded YouTube stream, based on Contabo’s published resources rather than a streaming benchmark. Move to Cloud VPS 6 or above when your encoder uses substantial CPU, you need several processes, or testing shows that the smaller plan leaves too little headroom.
That recommendation is an inference, not a guarantee. Contabo’s advertised port speed is not a measurement of sustained upload performance or uptime, so you should test the exact video, encoder settings and region before trusting a VPS with an unattended channel.
The practical starting point
For a single prerecorded devotional loop, bhajan channel, study stream or simple local information channel, begin by sizing the workload rather than choosing the largest plan. The important inputs are the output resolution, frame rate, codec, bitrate, encoder preset, audio settings and whether the VPS will run anything else.
Contabo’s U.S. pricing page lists Cloud VPS 4 with 4 vCPU, 8 GB RAM, 100 GB SSD and a 200 Mbit/s port. Those resources make it a plausible first plan for one relatively simple stream. They do not prove that it will encode every 1080p video smoothly, nor do they establish how consistently the advertised network port will perform over a continuous broadcast.
A higher plan is sensible when the encoder is close to full CPU usage, the system begins swapping memory, you are running more than one stream, or you need additional room for other services. More vCPU and RAM can help with those workloads, but a larger plan is not automatically a cure for a bad source file, unsuitable encoder settings, a congested route or a YouTube-side interruption.
If you want to understand the wider workflow before choosing a VPS, the 24/7 streaming checklist is useful alongside this plan comparison. It covers operational checks that a bigger VPS cannot replace.
What Contabo publishes for Core Cloud VPS plans
The current Contabo U.S. pricing page presents the following Core Cloud VPS specifications. Product names, regional availability, taxes and displayed prices can change, so confirm the live storefront before ordering. The effective monthly prices shown on that page are tied to a 24-month subscription and include applicable taxes as displayed there, rather than representing a universal month-to-month price.
| Plan | Published resources | Possible fit for one YouTube stream |
|---|---|---|
| Cloud VPS 4 | 4 vCPU, 8 GB RAM, 100 GB SSD, 200 Mbit/s port | A cautious starting point for one simple stream after testing |
| Cloud VPS 6 | 6 vCPU, 12 GB RAM, 200 GB SSD, 300 Mbit/s port | More room for a heavier encoder or additional processes |
| Cloud VPS 8 | 8 vCPU, 24 GB RAM, 300 GB SSD, 600 Mbit/s port | Worth considering for higher-resolution or multiple-stream work |
| Cloud VPS 12 | 12 vCPU, 48 GB RAM, 400 GB SSD, 800 Mbit/s port | A large resource step, not shown by this research to be necessary for one ordinary stream |
These figures are from Contabo’s current pricing page as listed in September 2026. They are published specifications, not independent measurements. Do not treat the port column as an uptime commitment, a guaranteed throughput figure or a result from a continuous YouTube test.
The plan family also matters. Do not combine the specifications of Core Cloud VPS, another Cloud VPS family or a Performance VPS as if the names were interchangeable. If you compare a VPS with a VDS, check how resources are allocated. Contabo describes ordinary VPS vCPU cores as shared, while VDS resources are presented with dedicated cores and guaranteed RAM. That may matter when consistent compute performance is important, but the available information does not establish that choosing a VDS improves YouTube network uptime.
Pricing needs the same care. A lower displayed monthly figure may be connected to a longer billing commitment, a particular storefront and a particular tax treatment. Compare the term, total commitment, region and traffic conditions, not only the number shown beside the plan name.
Contabo also describes traffic as unlimited subject to fair-use language. Its pricing page states: “If usage is exceptionally high or disruptive, Contabo reserves the right to throttle servers at its own discretion.” That qualification matters for an unusually continuous outbound video workload. Read the current terms and ask Contabo whether your planned persistent stream fits its conditions before you commit.
Turn bitrate into network demand
The stream bitrate is the part you can estimate most directly. If YouTube receives video at 8 Mbps and audio at a separate rate, the total outbound demand is slightly above 8 Mbps. The encoder may also produce small variations, and protocol overhead means the network does not carry only the exact video number.
YouTube’s current encoder guidance lists H.264 at 720p30 with a 3 Mbps minimum and 8 Mbps recommended rate. For H.264 at 1080p30, it lists a 5 Mbps minimum and 14 Mbps recommended rate. These are encoder settings for YouTube ingest, not promises about what a Contabo VPS can deliver.
YouTube recommends leaving about 20% bandwidth headroom and using a reliable connection. In practical terms, a stream configured at 14 Mbps should not be planned around a connection that is expected to sit precisely at 14 Mbps. Allow room for the audio stream, protocol overhead, normal variation and other traffic from the machine.
A simple planning method is:
required upload capacity ≈ total stream bitrate × 1.2
For a single 1080p30 H.264 stream at the recommended 14 Mbps video rate, that gives a planning figure of about 16.8 Mbps before allowing for other services or unusual bursts. For a 720p30 stream at the recommended 8 Mbps video rate, the equivalent planning figure is about 9.6 Mbps. These figures are only capacity estimates. They do not measure the path between your chosen VPS and YouTube, and they do not predict packet loss or stability.
The same calculation becomes more important when you run several outputs. Two streams at 14 Mbps each require roughly 28 Mbps of video bitrate before headroom. Three require roughly 42 Mbps. Audio, overhead, system traffic and monitoring still sit on top. A 200 Mbit/s advertised port appears much larger than those figures, but the comparison remains theoretical until you measure sustained delivery from the actual instance.
Resolution is not the only factor. A static image with gentle audio may be visually simple, while a fast-moving slideshow, scrolling news ticker or detailed camera feed can be harder to encode at the same resolution and frame rate. Codec choice also changes the balance. YouTube lists H.264, H.265 and AV1 as supported video codecs, but the codec you choose must be supported by your encoder and should be tested through the whole workflow.
For a bitrate and file-preparation workflow, see how to convert videos for a YouTube loop stream using HandBrake. Preparing a sensible source can reduce unnecessary encoder work before you start comparing VPS tiers.
CPU and memory are separate decisions
Network capacity is only one part of a software-encoded stream. The VPS must read the source, decode it if necessary, scale or filter it, encode the output and send it to YouTube. CPU demand depends on the codec, resolution, frame rate, encoder preset and complexity of the pictures.
A faster preset generally spends less CPU by doing less compression work, while a slower preset can use more CPU to produce a smaller or more efficient output. For a continuous channel, avoiding a CPU setting that leaves the machine permanently close to its limit is usually more useful than chasing a theoretical compression improvement. The exact balance should be measured with the encoder and source you intend to use.
A basic FFmpeg process may be comfortable on Cloud VPS 4, but that cannot be concluded from the vCPU count alone. Shared vCPU scheduling, the source format and the selected encoder all affect the result. Watch total CPU use during the busiest part of the content rather than checking only the average from a quiet opening frame.
Memory is often less demanding than CPU for one simple stream, but 8 GB is not all available to the encoder. The operating system, file cache, monitoring tools and any process used to restart or supervise the stream also need memory. Large source files do not normally mean that the whole file must be loaded into RAM, but inefficient applications can still create avoidable pressure.
Look for sustained signs of trouble rather than a single momentary spike:
- CPU remains near its limit and the encoder reports skipped or delayed frames.
- The process accumulates a growing delay instead of keeping pace with the source.
- Memory use continues rising, or the operating system begins swapping.
- The output bitrate falls below its target or fluctuates in a way the encoder cannot recover from.
- The stream preview shows repeated buffering, missing video or audio problems.
A VPS plan cannot correct a source with an incompatible frame rate, a damaged file or an audio configuration that fails during looping. If you run a radio or music channel, check the common causes of no sound on a 24/7 YouTube radio stream before interpreting an audio fault as a resource problem.
When Cloud VPS 6 or above makes sense
Cloud VPS 6 is the most natural next step when Cloud VPS 4 is close to its limits but the workload is still modest. Contabo lists 6 vCPU, 12 GB RAM, 200 GB SSD and a 300 Mbit/s port for this plan. The additional resources may provide more room for a slower encoder preset, a filter, a second process or a second output.
That is still a sizing judgement, not a benchmark. The published specification does not say that Cloud VPS 6 will maintain a particular YouTube stream, and it does not show how much CPU any particular file will consume. Move up because your measurements and workload justify it, not because the plan number sounds safer.
Cloud VPS 8, listed with 8 vCPU, 24 GB RAM, 300 GB SSD and a 600 Mbit/s port, may be reasonable when you have several streams, higher-resolution material, heavier filters or other services sharing the machine. A larger plan can also give you more room to investigate a problem without immediately stopping the stream. It should not be selected merely because its port number is larger.
Cloud VPS 12 is a substantial resource increase, listed with 12 vCPU, 48 GB RAM, 400 GB SSD and an 800 Mbit/s port. The available evidence does not show that one ordinary stream needs it. Consider it only after you have documented a genuine requirement, such as several demanding encoders or a larger workload on the same instance.
For a single uncomplicated loop, buying a larger tier before testing may leave you paying for unused CPU and memory. For a channel that earns its audience through long uninterrupted sessions, choosing the smallest plan without a test can create a different cost: overnight failures that are difficult to diagnose. The sensible middle path is to start with a defined workload, measure it for an extended period and keep a migration plan.
Port speed is not sustained throughput
A port speed is a property published for the plan. Sustained throughput is what your instance actually sends successfully over time to YouTube. They are related, but they are not the same measurement.
The delivered result can be affected by the VPS host, shared network conditions, routing between the data centre and YouTube, congestion, packet loss, traffic shaping and the behaviour of the application. A 200 Mbit/s port does not mean that a stream will always upload at 200 Mbit/s. Nor does moving to an 800 Mbit/s port establish that a single 14 Mbps stream will be more reliable.
The port is also not an uptime statistic. A broadcast can fail because of an encoder crash, an operating system issue, a restart, a credentials problem, a route interruption or a YouTube-side event. A larger advertised port does not remove those failure modes.
Run a controlled upload test from the actual VPS region and instance after deployment, but interpret the result cautiously. Test at a rate above your intended stream demand without treating that test as proof of future uptime. Repeat at different times if possible, record latency and packet loss, and watch whether the application can send continuously rather than only completing a short burst.
The traffic policy deserves equal attention. Contabo’s fair-use wording means that “unlimited” should not be read as an unconditional promise for every continuous workload. Keep a copy of the applicable terms, note the storefront and date, and contact the provider if a 24/7 outbound video stream is the main purpose of the server.
Test the exact stream before relying on it
A proper test uses the same source file, output resolution, frame rate, codec, bitrate, audio settings and restart process that you intend to use after launch. Testing a short low-resolution clip tells you very little about a demanding 1080p loop.
First, create or select the YouTube live event and configure the encoder for RTMPS where supported. YouTube recommends RTMPS for standard ingest. Its encoder guidance also recommends constant bitrate and a two-second keyframe interval, with the interval not above four seconds. Apply those settings consistently rather than changing several variables during the same test.
Then run the stream long enough to reach the part of the source that places the greatest load on the encoder. A quiet devotional still and a fast animated visual do not exercise the system in the same way. If the channel will loop a long file, test the transition from the end back to the beginning as well. Watch for audio discontinuities, dropped frames, growing delay and any process that stops after the first loop.
Monitor both the VPS and YouTube. On the VPS, record CPU, memory, swap activity, disk space, process state and outgoing traffic. In YouTube Studio, inspect the stream health, preview and warnings. YouTube’s guidance recommends testing ahead, checking the preview and monitoring the stream. Those practices are more informative than selecting a tier solely from its port label.
Test recovery, not only steady state. Stop the encoder and confirm that your supervisor restarts it. Temporarily interrupt the process in a controlled way and check whether the stream returns without leaving multiple encoders running. Confirm that the stream key is stored securely and that a restart does not require someone to be awake at an inconvenient hour.
A cloud workflow can remove the need to leave your home computer running. For example, StreamNeo is designed for the specific hand-off where you upload the video once, provide the YouTube stream key and let the channel run without installing software or keeping your computer switched on. That does not remove the need to check rights, channel eligibility or YouTube stream health, but it avoids having to maintain an encoder process on your own VPS.
If you do choose to manage FFmpeg yourself, the FFmpeg-on-a-VPS guide for a continuous YouTube stream is the relevant operational reference. Treat any guide as a starting configuration and validate it against your own file and account.
Account, rights and continuity checks
The VPS decision does not settle whether your channel can go live or whether the content may be broadcast. YouTube’s live-streaming requirements include channel verification and no live-stream restrictions within the preceding 90 days. First-time live-stream enablement may take up to 24 hours. Check the current YouTube live-streaming requirements before planning a launch date.
You also need the rights required for the material you broadcast, including music, images, footage and recordings. YouTube’s live-stream terms require the rights needed for the relevant use, including applicable worldwide rights, and you remain responsible for following applicable law. A VPS provider cannot grant those rights and no hosting plan guarantees that a broadcast will avoid a claim or restriction.
For a continuous channel, prepare a fallback. Keep the original source files, encoder settings and stream key procedure documented. Decide what you will do if the VPS is unavailable, the encoder fails or YouTube asks you to verify something. A second stream or a separate provider may be justified for a business-critical channel, but it introduces extra cost and operational complexity.
A fixed live URL can matter when viewers, embeds or social profiles already point to the channel. Plan the YouTube event and restart behaviour carefully rather than assuming that every encoder failure creates the same viewer experience. If your channel is built around music, the guidance on keeping the same live URL for a 24/7 YouTube music stream covers a related continuity concern.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Is Contabo Cloud VPS 4 enough for one 24/7 YouTube stream?
It is a plausible starting point for one relatively simple software-encoded stream because Contabo lists 4 vCPU and 8 GB RAM. That conclusion is inferred from the published specification, not from a Contabo-specific continuous streaming benchmark. Test the exact source and encoder before relying on it.
Should I choose Cloud VPS 6 for 1080p streaming?
Not automatically. YouTube’s recommended 1080p30 H.264 video bitrate is 14 Mbps, but bitrate alone does not determine CPU demand or network reliability. Choose Cloud VPS 6 when your encoder measurements, additional processes or required headroom justify its extra resources.
Does a 600 Mbit/s or 800 Mbit/s port guarantee a better stream?
No. The port figure is an advertised plan specification, not a measurement of sustained delivered throughput or an uptime guarantee. Routing, congestion, shared resources, encoder behaviour and failures elsewhere can still affect the broadcast.
Is unlimited traffic suitable for a continuous video stream?
Contabo’s traffic wording is qualified by fair-use terms, including the possibility of throttling exceptionally high or disruptive usage. Read the current terms for your storefront and ask Contabo to confirm that your planned continuous outbound workload is acceptable before purchase.
