How it works

AI handles compression, ASIC handles latency

The Lemonflex encoding pipeline works along two axes. AI allocates bits where they matter most; the ASIC encodes them as fast as possible.

01Pipeline

AI preprocessing × ASIC encoding

Before frames reach the ASIC encoding path, an AI model separates what viewers notice from what they do not. Removing noise while preserving detail means the same perceived quality costs fewer bits.

In-house ASIC × sub-frame latency

Encoding ASIC logic implemented on the ALVEO U250 keeps latency far below GPU pipelines. It drops straight into live broadcast, video conferencing, cloud gaming, and teleoperation workloads.

Use Cases

Wherever video flows

From live delivery to VOD, surveillance, and remote control. Any workload where video quality and latency matter.

Live broadcast · OTT

Low latency and high compression efficiency cut delivery cost and raise quality at once.

Sports & event coverage

AI preprocessing on multi-channel 4K and HDR workflows lifts perceived viewing quality.

VOD transcoding

Re-encode large catalogs at lower bitrates to cut storage and CDN spend.

Security & surveillance

Restore low-light, noisy footage while encoding large channel counts efficiently.

Teleoperation & robotics

Sub-frame latency supports remote control and teleoperation scenarios.

Cloud gaming · XR

Ultra-low-latency encoding protects the experience in interactive video workloads.

How to adopt

From validation to production, in stages

Nothing changes all at once. We validate on your real content, confirm stability on a subset of channels, then migrate. Every stage leaves documented output.

01Discovery

Define requirements

Typically 1–2 weeks

We map your current workflow, channel count, target quality and latency, and security requirements — then agree on the metrics that define success.

Deliverables
  • Current-state analysis
  • Target metric definition
  • Candidate configurations
02PoC

Validate on real content

Typically 2–4 weeks

We measure bitrate, VMAF, and latency on your actual content, running in parallel with your existing encoder so the delta is a number, not a claim.

Deliverables
  • Measurement report (VMAF · bitrate · latency)
  • Before / after samples
  • Recommended profiles
03Pilot

Run a subset of channels

Typically 4–8 weeks

Before full migration, a subset of channels goes into real operation. We confirm stability and operational load, and finish tuning.

Deliverables
  • Operational design document
  • Monitoring and alerting setup
  • Handover documentation
04Production

Full migration & operation

Typically Ongoing

Channels migrate in stages and operation moves onto an SLA basis. Regular reviews keep profiles and configuration optimized.

Deliverables
  • SLA agreement
  • Scheduled performance reviews
  • Dedicated support channel

Timelines and scope adjust to channel count and environment.

When live delivery stops, the loss is immediate. Choose response times and coverage based on operational criticality. Specific SLA terms are finalized at contract.

FAQ

Questions we hear before adoption

The questions that come up most during evaluation. Anything not covered here, we answer directly in a technical meeting.

Request a technical meeting

Under what conditions were the performance figures measured?

The bitrate savings shown on this site are internal measurements against a software encoder while holding VMAF constant; quality-gain figures are measured on identical content at identical bitrates. Because the margin varies with content complexity, we provide a report measured on your own content during PoC.

Do we have to replace all of our encoding equipment?

No. We recommend running a subset of channels in parallel to compare quality and bitrate, then migrating in stages. Because output is a standard codec, your players, CDN, and packager stay as they are.

Can on-premises and cloud be used together?

Yes. They share the same engine and the same API, so the common arrangement handles steady-state traffic on-premises and bursts peak traffic to the cloud. Profiles validated on-premises apply to cloud unchanged.

Our content must not leave our network. Is that possible?

With on-premises deployment, content and traffic never cross your network boundary. Licensing uses an offline file, so operation in an air-gapped network requires no external communication.

How long does adoption take?

A typical timeline is 1–2 weeks to define requirements, 2–4 weeks for PoC, and 4–8 weeks for a pilot. Smaller card-only deployments are faster; large channel migrations take longer. Tell us your target date and we will work backwards from it.

Do we need a proprietary codec or a dedicated player?

No. Output is H.264, HEVC, or AV1 only, packaged as HLS, DASH, or CMAF. No vendor lock-in is created, and you can revert to another encoder at any time.

How is pricing determined?

On-premises pricing is based on card or appliance quantity and SLA tier; cloud pricing on processing resolution and duration in minutes. Tell us your channel count and expected volume and we will prepare a quote.
