Live streaming runs on two workflows, not one.
The source-side workflow captures your camera or screen, encodes it in software (OBS Studio, vMix) or on hardware (Atomos Connect, Haivision Makito), and pushes a single stream to the cloud over RTMPS or SRT.
The cloud delivery workflow receives that stream, transcodes it into adaptive bitrate ladders, packages it as HLS or LL-HLS, and distributes it to viewers across a CDN. Without the cloud delivery side there is no stream a thousand viewers can actually watch.
This article compares the eight encoders that matter across both workflows, with depth on the cloud delivery side where the decision sticks.
TL;DR:
- The decision that scales or doesn't: pick the cloud encoder. FastPix Live Streaming is the API-first, self-serve pick for engineering teams (single endpoint, 30 minutes of free live streaming to try, native LL-HLS, official vMix partnership, supports OBS, Wirecast, Atomos, and Haivision via RTMPS/SRT). AWS Elemental Live is the enterprise pick for teams already deep in AWS. Bitmovin Live Encoder is the pick for OTT platforms running Bitmovin VOD.
- The software or hardware encoder: pick what fits your production setup, then move on. OBS Studio for solo or simple live. vMix or Wirecast for multi-camera events. Atomos Connect or Haivision Makito X for field broadcasting with cellular bonding or broadcast-grade reliability.
The cloud encoder choice determines whether your stream reaches a thousand viewers at sub-3-second latency or stalls at a hundred. The software or hardware encoder choice determines whether your producer can switch between camera angles without dropping the broadcast. Engineering time goes into the first decision. Production time goes into the second.
Cloud encoders: where the production decision sits
The cloud encoder runs the delivery workflow: receiving the source stream, transcoding into adaptive bitrate ladders, packaging as HLS or LL-HLS, distributing through a CDN, and handling operational concerns like recording, clipping, and simulcast. This is where the production decision lives because the cloud encoder choice determines scale, latency, reliability, and how much engineering time you spend on infrastructure rather than product.
Three cloud encoders cover the practical market for engineering teams building live workflows into a product: FastPix Live Streaming, AWS Elemental Live, and Bitmovin Live Encoder. All three ingest RTMPS and SRT, transcode into ABR ladders, package as HLS, and deliver via CDN. Where they diverge is how much of your engineering and DevOps time they consume on the way to a working pipeline, and how their pricing scales with actual usage.
FastPix Live Streaming
FastPix Live Streaming is the cloud encoder built for engineering teams that want a working pipeline behind a single API call. Ingest accepts RTMPS or SRT at a single endpoint. ABR transcoding, HLS packaging, and LL-HLS packaging happen automatically. Live-to-VOD recording is on by default, so every stream archives as a VOD asset without a separate workflow. Live clipping during the event is a single API call, not a custom build. Simulcast destinations are programmable through the same API.
The developer experience is the differentiator. New accounts get 30 minutes of free live streaming to try the platform end-to-end, no credit card required. Pricing past the trial is pay-as-you-go, so you only pay for what you actually use rather than committing to seats or input hours in an enterprise contract. For a team shipping live into a product, this means signup to first ingest endpoint is an afternoon, and the bill scales with how viewers actually use your stream.
Source-side compatibility is broad. FastPix is an official partner of vMix, with ingest endpoints designed around the protocols vMix sends. OBS Studio, Wirecast, Atomos Connect, and Haivision Makito X all push to the same RTMPS or SRT endpoints with a single URL plus stream key. Engineering teams that already standardize on a contribution tool do not have to change anything on the source side to switch to FastPix.
| Field | Value |
|---|---|
| Type | Cloud (API platform, ingest + transcode + delivery) |
| Protocols | RTMPS, SRT ingest; HLS, LL-HLS output |
| Price | Pay-as-you-go; 30 minutes of free live streaming to try, no credit card required |
| Source-side | Official vMix partner; supports OBS, Wirecast, Atomos, and Haivision via RTMPS or SRT |
| Best for | Engineering teams building live workflows into a product; sports, OTT, live commerce |
| Biggest weakness | Newer entrant compared to AWS Elemental; smaller integration partner ecosystem |
AWS Elemental Live
AWS Elemental Live is the managed live encoding service inside AWS Elemental Media Services. The pipeline is composed from MediaLive (encoding), MediaPackage (packaging), and MediaTailor (ad insertion and personalization). It is not a single product; it is a stack you assemble. Used by enterprise broadcasters with large AWS footprints and dedicated DevOps capacity, where the AWS lock-in is a feature rather than a tax.
The strength is integration depth across AWS: S3 for storage, CloudFront for delivery, IAM for access control, Step Functions for workflow orchestration. The cost is operational. Composing MediaLive plus MediaPackage plus MediaTailor into a working pipeline is several weeks of engineering before the first viewer sees a stream, and pricing surprises tend to land in invoices rather than in the docs.
| Field | Value |
|---|---|
| Type | Cloud (AWS service stack: MediaLive + MediaPackage + MediaTailor) |
| Protocols | RTMPS, SRT, MPEG-TS ingest; HLS, DASH, CMAF output |
| Price | Per-input-hour ($1.20–$8.00/hr depending on resolution and codec) |
| Best for | Enterprise broadcasters already deep in AWS; regulated workloads |
| Biggest weakness | Operationally complex; multi-service composition; pricing surprises at scale |
Bitmovin Live Encoder
Bitmovin Live Encoder is the live encoding service from Bitmovin, paired with their VOD encoder and player. CMAF and LL-HLS support are strong because Bitmovin's encoding team built both. Per-title encoding optimization applies to the live side. The fit is OTT platforms that already run Bitmovin VOD and want the same encoding team handling live workloads.
The catch is the sales motion. Bitmovin is enterprise-quoted, not self-serve. Evaluating the platform means going through a sales process before you can test the ingest endpoint, which matters when your engineering team wants a free credit on a Tuesday and a working stream by Thursday.
| Field | Value |
|---|---|
| Type | Cloud (managed live encoding service) |
| Protocols | RTMPS, SRT, Zixi ingest; HLS, DASH, CMAF, LL-HLS output |
| Price | Custom enterprise quotes; usage-based |
| Best for | OTT platforms running both VOD and live workloads on Bitmovin |
| Biggest weakness | Enterprise sales motion; no self-serve evaluation |
The cloud encoder decision shapes everything downstream of it: how fast your team ships, how predictable your bill is, how much DevOps capacity you spend on infrastructure versus product. FastPix wins on time-to-first-stream and pricing predictability. AWS Elemental wins on integration depth into existing AWS estates. Bitmovin wins when you are already running Bitmovin VOD and want one vendor across both pipelines.
On the source side of the pipeline are the software and hardware encoders that feed the cloud. What you pick there depends on production complexity and reliability requirements; it does not change which cloud encoder is right.
Software encoders
Software encoders run the source-side workflow on your laptop or production machine. They take input from a camera, capture card, screen, or video file, encode it in software, and push the encoded stream to your cloud encoder over RTMPS or SRT. They range from free (OBS Studio) to roughly $2,000 (Wirecast Pro). The right pick when production happens at a desk or in a studio, with one or more cameras feeding a single workstation. None of them deliver streams to viewers on their own; they feed the cloud encoder that does.
OBS Studio. Free, open source, runs on Windows, macOS, and Linux. The default for solo creators, podcasters, B2B SaaS webinars, and small teams. Supports RTMPS and native SRT (built in since v26). Mature plugin ecosystem. Limitation: production complexity scales poorly past three or four camera setups. Output: one stream you push to your cloud encoder.
vMix. Paid Windows-only production software, $60 to $1,200. Built for multi-camera live: scene composition, picture-in-picture, chroma key, instant replay. Outputs RTMPS, SRT, NDI, HLS pull, RTSP. Limitation: Windows only, learning curve. Output: one stream you push to your cloud encoder.
Wirecast. Telestream's event production software, $599 to $1,799, Windows and macOS. Used for ticketed virtual events, religious broadcasting, and corporate live. Mature feature set, useful when you need Telestream's broader ecosystem. Output: one stream you push to your cloud encoder.
Hardware encoders
Hardware encoders run the source-side workflow on dedicated devices with onboard encoding silicon. They plug directly into camera HDMI or SDI, encode on-device, and push to your cloud encoder over RTMPS or SRT, no laptop required. Pricing starts around $2,000 and climbs past $15,000 for broadcast-grade units. The right pick when production happens in the field with unreliable connectivity, or when broadcast-grade reliability is contractual (live sports remotes, news ENG, ticketed events with no margin for failure).
Atomos Connect / Shogun Connect. Field hardware, $1,995 to $3,495. Plugs into camera HDMI/SDI, encodes on-device, pushes RTMPS or SRT to the cloud. Cellular bonding through the Atomos network is the differentiator for unreliable connectivity environments. Used for sports field reporting and news ENG. Output: one stream you push to your cloud encoder.
Haivision Makito X. Broadcast-grade hardware, enterprise pricing ($5,000+). Haivision wrote the SRT protocol and the Makito X line is the reference hardware for high-bitrate, low-latency streaming over unreliable IP networks. Used by major broadcasters for live sports remotes and breaking news. Output: one stream you push to your cloud encoder.
Software and hardware encoders share the same shape: produce a single encoded stream, push it via RTMPS or SRT. The cloud encoder is what turns that single push into a stream a thousand viewers can watch at sub-3-second latency.

Pricing accurate as of June 2026. Vendor pricing changes frequently; confirm current numbers with the vendor before committing to a purchase.
The HLS-out and LL-HLS-out columns make the workflow split visible: cloud encoders produce both for delivery to viewers, source-side encoders produce neither. This is the architectural reason your cloud encoder choice carries more weight than your source-side choice.
How to choose: a decision framework
Start with the cloud encoder. This is the decision that determines whether your stream scales and how much engineering time you spend on infrastructure rather than product.
- FastPix Live Streaming for engineering teams shipping live workflows into a product. API-first, self-serve, 30 minutes of free live streaming to try. Official vMix partner; supports OBS, Wirecast, Atomos, and Haivision via RTMPS/SRT. Single endpoint covers ingest, ABR transcoding, HLS and LL-HLS packaging, CDN delivery, Live-to-VOD recording, live clipping, and simulcast.
- AWS Elemental Live for enterprise broadcasters with dedicated DevOps capacity and a deep AWS footprint. Most low-level knobs, most operational overhead, most opportunity for pricing surprises at scale.
- Bitmovin Live Encoder for OTT platforms already running Bitmovin VOD that want one encoding vendor across both workloads. Enterprise sales motion required.
Then pick the software or hardware encoder. This is a production setup decision your team makes in a day. Solo or small team with one or two cameras runs OBS Studio. Multi-camera live runs vMix or Wirecast. Broadcast-grade field production with unreliable connectivity runs Atomos Connect or Haivision Makito X. None of these change which cloud encoder is right; any of them can push to any of the three cloud picks.
The combination of OBS Studio plus FastPix Live Streaming covers most small-to-mid live workloads at zero source-side cost plus usage-based cloud pricing. The combination of vMix plus FastPix Live Streaming covers multi-camera production with the same self-serve cloud platform underneath. For broadcast-grade field production into FastPix, Atomos Connect or Haivision Makito X push directly into the same RTMPS or SRT ingest endpoint without any custom integration work.
FAQ
What does "live streaming encoder" mean exactly?
In a production pipeline it means two different things. A software or hardware encoder (OBS Studio, vMix, a hardware box) produces one encoded stream from your source and pushes it to a destination. The cloud encoder (FastPix Live Streaming, AWS Elemental, Bitmovin) receives that stream and transcodes it into adaptive bitrate ladders, packages it as HLS or LL-HLS, and delivers it to viewers. When engineering teams talk about the encoder for a live product, they mean the cloud encoder, because that is what determines scale, latency, and reliability.
Can OBS Studio deliver a live stream to viewers on its own?
No. OBS produces one encoded stream and pushes it to a destination via RTMPS or SRT. To deliver that stream to viewers, the destination needs to transcode it into multiple renditions for adaptive playback, package it as HLS or LL-HLS, and serve it through a CDN. OBS does none of that. The cloud encoder downstream does all of it. This is why a production live streaming pipeline always has at least two encoders.
Why does the cloud encoder choice matter more than the software or hardware encoder?
Because the cloud encoder determines whether your stream actually reaches viewers. A software or hardware encoder only produces a single stream pushed to one destination. The cloud encoder ingests that stream, transcodes it into multiple resolutions and bitrates for ABR playback, packages it as HLS or LL-HLS segments, distributes it via CDN, and handles operational concerns (recording, clipping, simulcast, analytics). Switching software or hardware encoders is a day of work. Switching cloud encoders is a re-architecture.
What does FastPix Live Streaming do that AWS Elemental doesn't?
FastPix exposes the full ingest-to-delivery pipeline as a single API call against a single endpoint, with 30 minutes of free live streaming on signup and no credit card required to try the platform end-to-end. FastPix is an official vMix partner and supports OBS Studio, Wirecast, Atomos, and Haivision via RTMPS or SRT, so engineering teams that already use a contribution tool do not have to rework the source side. AWS Elemental requires composing MediaLive (encoding), MediaPackage (packaging), and MediaTailor (ad insertion) into a working pipeline with separate billing meters on each. For an engineering team that wants a working stream by tomorrow, FastPix is hours to first stream; AWS Elemental is weeks. For an enterprise broadcaster already running infrastructure across AWS, the composition tax may be worth it. For a team building live into a product, it usually isn't.
Should I use a hardware encoder for live streaming?
Only when the source side has to survive unreliable networks or contractual reliability requirements. Hardware encoders ($2K to $15K+) make sense for field broadcasting with cellular bonding (Atomos Connect) or broadcast-grade streaming over unreliable IP (Haivision Makito X). The hardware encoder still pushes to a cloud encoder downstream; it solves the source-side reliability problem and nothing else.
What is the difference between RTMPS and SRT for ingest?
RTMPS is the widely-supported legacy standard, tuned for stable connections. SRT is newer, designed for unreliable networks (cellular, hotel WiFi, transcontinental links), with built-in packet recovery and forward error correction. Use SRT when the source-side network is unpredictable. Use RTMPS when the ingest leg is stable and you want maximum encoder compatibility. FastPix Live Streaming accepts both at the same endpoint without configuration changes.
Can I use FastPix Live Streaming with OBS Studio?
Yes. FastPix accepts RTMPS or SRT ingest from any software or hardware encoder. Configure OBS the standard way with the FastPix ingest URL and your stream key, no plugin or wrapper required. vMix is an official partnership with ingest endpoints designed around the protocols vMix sends. Wirecast, Atomos Connect, and Haivision Makito X push to the same endpoints over RTMPS or SRT without any custom integration. On the other side, you get ABR transcoding, HLS and LL-HLS packaging, CDN delivery, Live-to-VOD recording, and live clipping for the same stream.
When does AWS Elemental Live make sense over FastPix?
When your team is already deep in AWS, has dedicated DevOps capacity, wants per-input-hour billing rather than usage-based, and is willing to compose MediaLive plus MediaPackage plus MediaTailor into a working pipeline. AWS Elemental gives you the most low-level knobs and the most operational overhead. FastPix exposes the full pipeline behind a single API, which is faster to ship and easier to support but less customizable at the infrastructure level. The trade-off is real and depends on whether you have AWS DevOps capacity to spend.
