Adaptive Bitrate Streaming for Buffer Free Playback

The spinner is the only thing viewers never forgive. Every title is encoded as a set of renditions, and the player moves between them as the connection changes.

Viewers Forgive a Softer Picture, Not a Stopped One

Vodlix adaptive bitrate streaming is built on a simple truth: the loading spinner is the only thing viewers never forgive. Ask a viewer what quality they watched at and they do not know; ask whether it stopped and they know exactly how often. Adaptive delivery optimises for the thing that matters, keeping playback continuous by adjusting quality to the connection. For OTT operators, adaptive streaming is the foundation of viewer satisfaction on every network.


Multiple renditions

Encoded per title.

Automatic switching

Best rendition for the moment.

No stalls

A softer picture, never a stopped one.

Always the Best Quality the Connection Can Sustain

With Vodlix adaptive bitrate streaming, every title is encoded as a set of renditions at different resolutions and bitrates, and the player continuously picks the best one the connection can sustain. It does not chase a top quality that stalls the moment anything changes; it selects the highest quality that will play without interruption. Selection happens automatically, segment by segment. In a test session on a 4K title, throttling the connection to 3 Mbps moved the web player from 2160p to 360p within seconds, and playback never stopped.


Graceful Quality Drops and Automatic Recovery

A Vodlix viewer on a weak connection, on a train or on congested wifi, gets a softer picture rather than a stopped one, and never has to think about why. When the connection improves, quality steps back up automatically as the player measures the extra bandwidth. The viewer sees a film that keeps playing; the switching is invisible. Graceful degradation and recovery are what make streaming reliable in the real conditions viewers actually watch under.


Built on Your Encoding Ladder

Vodlix adaptive delivery works from the renditions you enable under Encoding & Security, from 240p up to 2160p, so the quality steps available to the player match what your audience can actually receive. A ladder tuned to your markets keeps delivery efficient and playback smooth. Plans can set a ceiling on top: each package states whether HD and Ultra HD are available. Encoding, adaptation and tiering work together as one system, which is what keeps streaming both cost effective and dependable.


Encoding & Security settings, Enabled Resolutions: SD 240p, 360p, 480p, HD 720p, 1080p and UHD 1440p, 2160p renditions

Frequently Asked Questions

Have questions about taking advantage of this limited-time offer? Check out the FAQ for answers.

What is adaptive bitrate streaming on Vodlix?
Vodlix adaptive bitrate streaming encodes each title as several renditions at different resolutions and bitrates, and the player switches between them automatically as the viewer's connection changes.
Why not just serve the highest quality to everyone?
The highest quality stalls the moment a connection dips, and a stall costs far more viewer goodwill than a softer picture. Vodlix adaptive streaming optimises for uninterrupted playback.
What does a viewer on a weak connection experience?
A Vodlix viewer on a weak connection gets a lower resolution but uninterrupted stream, and quality steps back up automatically when the connection improves, without any action from them.
Do viewers have to choose a quality setting on Vodlix?
No. The Vodlix player starts on Auto and selects the best sustainable rendition segment by segment. Viewers who want a fixed quality can pick one from the player's Settings menu.
Where do the adaptive streaming renditions come from?
The renditions Vodlix adapts between are the encoding ladder you enable under Encoding & Security, anywhere from 240p to 2160p. A package can also cap the top quality by leaving HD or Ultra HD unavailable.
Does this work for live channels too?
Yes, when the live stream carries several renditions: the same player adapts between them. It matters more there, because a live stream has far less buffer to absorb a problem, and a channel delivered as a single rendition has nothing to step down to.
Is adaptive streaming enough on its own?
No. It reduces how much has to be sent, and a content delivery network reduces how far it travels. Getting one right and the other wrong still produces a service that feels slow, so the two are worth treating as halves of the same problem.
Can I see what quality viewers actually received?
Not per rendition. Insights reports views, watch time and completion per title, and CDN Analytics reports bandwidth, requests and cache hit rate, so you can see how much was delivered and where, but there is no report of which rendition each viewer watched.
