AWS Elemental Live is an on-premises real-time video encoder and transcoder, available on hardware appliances or virtual machines. It can process UHD video up to 4K, but the usable formats, output codecs, licensing, and number of simultaneous encodes depend on the specific input, output configuration, and deployment capacity. It is one part of a live delivery chain—not a complete streaming destination or consumer live-streaming service.
What AWS Elemental Live does
Elemental Live ingests a live source, transforms its video and related audio, captions, or metadata, then sends configured outputs to downstream systems. AWS describes events as the unit of work: an event combines one or more inputs with output groups that define encoding and packaging. See AWS’s workflow overview.
A typical chain is source signal → Elemental Live → origin service or packager → content delivery network (CDN) → playback device or website. Elemental Live handles live encoding and transcoding; the rest of the chain delivers and presents the resulting stream.
How an Elemental Live workflow is assembled
- Identify the source. Establish where the live signal comes from, its video and audio formats, and the physical or network interface used to ingest it. AWS’s supported-codecs documentation describes format support; interface-specific requirements must also be checked.
- Configure the event input. An input identifies and ingests the source content and its associated components, such as audio, captions, and metadata.
- Choose output groups. Each output group specifies how the encoded stream is packaged and where it is sent. Select the destination and packaging based on the downstream origin or packager and the playback devices that must work.
- Set each output’s encoding parameters. Choose codec, resolution, frame rate, bitrate and rate-control behavior, GOP, and other quality controls for each output stream.
- Start the event and verify downstream playback. Confirm that the source is being ingested, outputs reach their configured destinations, and the origin/CDN and target players handle the chosen format.
4K UHD, color, and input formats
AWS distinguishes resolution from color space: Elemental Live supports SD, HD, and UHD resolutions, with UHD extending up to 4K, and supports SDR and HDR color spaces. SDR can be paired with SD, HD, or UHD; HDR is typically paired with HD or UHD. These capabilities do not mean every input interface, codec, and output combination supports every UHD/HDR format. Check the exact path from source through output. See AWS’s color-space and resolution guidance.

SMPTE 2110-specific requirements
For SMPTE 2110, AWS documents uncompressed video at SD, HD, and 4K, with 4:2:2 chroma sampling and 10-bit depth. The workflow requires PTP locking for proper synchronization; without it, media streams can become unsynchronized during processing. These are SMPTE 2110 details, not general guarantees for every Elemental Live input. See AWS’s supported-content documentation.
H.264 and HEVC output choices
Codec availability is tied to the output group and container, not just to the encoder’s overall feature list. AWS lists H.264 and H.265/HEVC for DASH and for standard and fMP4 HLS live outputs; RTMP lists H.264. Other output groups and containers have their own combinations. Check the exact row for the output group and container you intend to use in AWS’s live output codec matrix.

ZowieBox enables bidirectional conversion between HDMI and SRT streams, allowing reliable remote production, live streaming, and video contribution workflows with high-quality transmission even across long-distance networks.
HEVC licensing and format distinctions
AWS’s HEVC support table separates input from output and specifies chroma sampling, bit depth, and profile. It lists HEVC input support for 4:2:0 at 8- and 10-bit and 4:2:2 at 8- and 10-bit. For HEVC output, AWS lists the HC license for 4:2:0 and the BCE license pack for 4:2:2. The table also notes that raw outputs and MPEG-2 transport streams support both 4:2:0 and 4:2:2, while other containers support only 4:2:0. Confirm the relevant license and container support for the precise workflow with AWS; input support does not by itself establish output or licensing eligibility. Details are in AWS’s HEVC (H.265) documentation.
Plan capacity for the actual rendition stack
There is no generally applicable 4K channel-count figure to rely on. AWS identifies aggregate output pixels per second as a key workload factor; resolution, frame rate, color depth, codec, and rate-control choices also affect processing demand. AWS’s documented relative ordering places HEVC above AVC in processing demand, but this is directional guidance rather than a throughput benchmark for a particular appliance or VM. See AWS’s performance parameters.

In distributed encoding, each rendition requires an output encode. AWS cautions that an appliance may handle only one output encode if that rendition is 4K, while lower-resolution renditions may allow several depending on the system’s density capabilities. Do not infer a guaranteed number of channels from resolution alone; validate the specific model or VM configuration against the complete workload. AWS’s input design guidance discusses the trade-offs.
CPU-only and GPU-enabled deployments
AWS says listed codecs can produce equivalent video quality at equivalent operating points on CPU-only and GPU-enabled appliances, and lists accelerated H.264 and HEVC encoding on GPU-enabled systems. Equivalent quality does not imply equal capacity or cost. Evaluate the intended model, deployment, and output workload rather than treating GPU support as a universal capacity multiplier. See AWS’s CPU and GPU codec guidance.

Set quality per output
Encoding quality is configured for each output stream. AWS lists controls including rate-control mode and bitrate, frame rate, GOP, quantization, lookahead, and the balance between density and quality. Tune these against the image quality and bitrate you need, available compute capacity, output latency requirements, and playback-device compatibility. Changing one output’s settings does not automatically configure every other rendition. See AWS’s video-quality controls.
Deployment checklist
- Document each source’s interface, resolution, frame rate, color space, bit depth, and chroma sampling.
- Map every destination to its required output group, container, codec, and playback support.
- Check HEVC licensing and the specific output format if using HEVC, especially for 4:2:2 output.
- Estimate the full simultaneous rendition workload, including aggregate pixels per second and frame rate, for the exact appliance or VM configuration.
- Confirm synchronization requirements for the selected input interface, including PTP for SMPTE 2110.
- Plan redundancy and downstream origin, packaging, and CDN behavior as part of the whole delivery chain.
- Validate capacity and compatibility with model-specific AWS documentation or AWS before committing to a channel count or production design.
When a cloud loop is a different fit
Elemental Live is designed for real-time encoding of live sources in a configured professional delivery pipeline. If the requirement is instead to keep uploaded prerecorded videos looping on a YouTube channel, StreamNeo is a simpler, different-purpose option: upload the video or build a playlist, add the YouTube stream key, and go live from the cloud. It does not encode a camera feed or replace an Elemental Live contribution workflow. Every StreamNeo slot streams uploaded content to YouTube at the quality supplied, up to 4K 60fps, with one flat price per slot; the first day is free with no card. See StreamNeo for details, then start the free day.
