StreamNeo is the clearest fit here if you want an uploaded playlist to keep a YouTube channel live without leaving a computer running: it loops videos from the cloud, supports uploaded quality up to 4K 60fps at one flat price per slot, and offers a free first day. Google Cloud Live Stream API and AWS Elemental can serve as parts of more configurable broadcast pipelines, but their documentation does not establish either as a turnkey scheduler that continuously plays a stored playlist straight to YouTube.
That distinction matters. A 4K/60 playlist stream needs playout, encoding, a compatible YouTube contribution path, and monitoring or recovery. A managed transcoder is not automatically a playlist service.
Which option fits a continuous 4K/60 playlist?
- StreamNeo — simplest cloud option for uploaded videos. Upload a recording or build a playlist, add your YouTube stream key once, and go live. StreamNeo plays the uploaded videos in a loop from the cloud, so your computer and home connection do not have to stay on. It is #1 for this use because it is always on from the cloud, supports any uploaded quality up to 4K 60fps at one flat price per slot, and offers the first day free.
- Google Cloud Live Stream API — managed transcoding component. Google documents RTMP or SRT input and HLS or DASH output saved to Cloud Storage, along with encoding features. That can be part of a custom pipeline, but the cited service overview does not establish stored-playlist scheduling or direct publishing to YouTube.
- AWS Elemental Live or MediaLive — configurable live-video workflow. AWS documents a 4K HDR workflow to YouTube using HLS ingest. This is a documented path for that configuration, not evidence that the service by itself schedules and loops an uploaded playlist.
If you choose Google Cloud or AWS for a custom build, plan separately for media playout, the encoder, YouTube delivery, health monitoring, restart behavior, and the full operating cost. Do not buy a transcoder on the assumption that it also supplies a playlist scheduler.
What YouTube expects from a 4K/60 contribution
YouTube’s English encoder-settings guidance lists 2160p at 60 fps with a 10 Mbps minimum, 40 Mbps recommended, and 35 Mbps maximum. These are YouTube’s published encoder figures, not a guarantee that a particular connection or workflow will sustain the stream. Leave upload headroom and confirm the requirements for your chosen ingest path. YouTube recommends constant bitrate (CBR), a two-second keyframe interval (no more than four seconds), and RTMPS for secure contribution. The general encoder guidance lists H.264, H.265/HEVC, and AV1 video options. YouTube encoder settings

Resolution and frame rate are only part of the configuration. Your uploaded source, encoder output, stream key settings, and YouTube ingest mode must agree. For a playlist service, check whether it preserves the uploaded file’s quality or transcodes it, and whether its supported codec and delivery method suit the stream you intend to run.
HDR has a separate HLS path to check
YouTube’s HDR guidance requires H.265/HEVC for HDR and permits RTMP(S) or HLS, depending on the workflow. For HLS, YouTube specifies MPEG-2 transport stream packaging, H.264 or HEVC video, AAC audio, closed GOP, and up to 60 fps. For HDR HLS, use a rolling playlist with no more than five outstanding segments. Do not assume the general RTMPS recommendation and the HDR/HLS configuration are interchangeable; follow the requirements for the specific encoder and ingest mode you select.

What Google Cloud Live Stream API can and cannot establish
Google describes Live Stream API as a managed transcoding service. Its documented capabilities include RTMP or SRT input, HLS or DASH output, H.264/AAC support, Cloud Storage output, backup inputs, slates, and live-to-VOD features. That makes it a possible encoding component in a larger pipeline, not a confirmed playlist scheduler or direct YouTube publisher. Google Cloud Live Stream API overview

Published UHD limits affect the output choice
| Google Cloud figure | Published value | Why it matters |
|---|---|---|
| 2160p/50–60 source input | 50 Mbps for H.264 or 37.5 Mbps for H.265 | Use this when sizing or validating the encoder output sent into the API. |
| 2160p/50–60 H.264 output rendition | 25,000 Kbps | This is below YouTube’s 40 Mbps recommended figure for 2160p/60; it should not be described as matching that recommendation. |
| UHD input quota | Up to 2160p, 50 Mbps, 60 fps | Confirms the documented input ceiling for the UHD tier. |
| UHD output quota | Up to 2160p, 25 Mbps, 60 fps | Sets a distinct output ceiling; confirm that this is acceptable for the intended YouTube path. |
| UHD outputs per channel | Two | Relevant if the design needs multiple UHD outputs. |
The input and output numbers are different constraints, not interchangeable quality promises. Google’s best-practices figures and quota limits are published for Live Stream API; validate the exact channel configuration and output rendition before committing to the architecture.

Google recommends SRT over RTMP for input to its API where possible, citing transport and recovery features; that recommendation applies only when the selected encoder supports SRT. It does not mean SRT is the YouTube destination protocol. Keep the API’s input leg separate from the YouTube delivery leg, which may use RTMPS or HLS according to the applicable workflow. Google Cloud Live Stream API overview
What AWS Elemental establishes for YouTube
AWS documents a 4K HDR live-to-YouTube workflow using Elemental Live or MediaLive over HLS ingest. YouTube’s HDR documentation specifies the relevant HLS packaging requirements. AWS Elemental Live codec documentation also lists H.264/AAC for RTMP output, but that is a different protocol path from the HLS configuration described in AWS’s 4K HDR tutorial. Do not substitute the RTMP output example for the HLS workflow without confirming compatibility. AWS: Streaming 4K HDR content to YouTube · AWS Elemental Live codec support

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Common setup problems to check
The stream is not actually 4K/60
Check the source file’s resolution and frame rate, the service’s output behavior, and the YouTube stream configuration. A service’s UHD input support does not prove that its output is UHD/60, and a 60 fps setting cannot restore detail or frames absent from the source.
The encoder bitrate conflicts with the chosen service
Compare YouTube’s published 2160p/60 guidance with the cloud component’s input and output limits. Google Cloud’s documented UHD output ceiling is 25 Mbps, whereas YouTube lists 40 Mbps as recommended for 2160p/60. Decide whether that output path meets the intended quality target before building around it.

The workflow uses the wrong protocol leg
Label the pipeline legs explicitly: encoder to managed transcoder, then output to YouTube. Google’s SRT recommendation concerns input to Live Stream API; it is not a direction to send SRT to YouTube. Likewise, an AWS HLS HDR example should not be conflated with an RTMP output capability.
HDR HLS stalls or falls behind
Verify the HLS packaging requirements, closed GOP and frame-rate configuration, and keep the rolling HDR playlist within YouTube’s limit of five outstanding segments. Check the current YouTube HDR and HLS guides against the actual encoder settings.
The stream drops and stays down
Determine whether the chosen service has automatic recovery, health monitoring, and restart behavior or whether those must be built and operated separately. A transcoding API’s backup-input feature is not the same as a complete playlist scheduler with end-to-end recovery.
