What is video QoE analytics?

Video QoE (quality of experience) analytics measures what playback actually feels like to a viewer: how fast it started, how often it buffered, whether it failed, and how sharp it looked. FastPix scores these into an Overall Experience Score per session so you can track and improve them.

How many dimensions can I track per session?

56 dimensions. 46 built-in (device, browser, OS, player, video metadata, network, geo, error flags). 10 customizable (custom_1 through custom_10).

Which players does Video Data support?

17 player surfaces: FastPix Player, Shaka, HLS.js, Video.js, DASH.js (web), AndroidX Media3, ExoPlayer, Brightcove, Bitmovin, Kaltura, THEOplayer (Android), AVPlayer (iOS), React Native, Better Player (Flutter), Samsung Tizen, LG webOS (Smart TV), Roku streaming device.

What is the 'Overall Experience Score'?

A composite QoE score combining Stability, Startup, Render Quality, and Playback Success into a single number per session. Useful for trend-tracking and per-segment comparison.

Can I stream events to my data warehouse?

Yes. Using the export API. Common destinations: Snowflake, BigQuery, Redshift, Databricks, ClickHouse.

How do I migrate from Mux Data or NPAW?

Swap the data SDK init call. Same playback-session model, same custom-dimension model. Most teams complete migration in a single sprint. FastPix vs Mux.

How is Video Data different from Mux Data?

Mux Data is the longest-running peer with the broadest reference customer roster. Video Data is FastPix-native: built into the same API and dashboard as the rest of FastPix, with the same per-minute billing. FastPix vs Mux.

Is there a free trial pathway?

Yes. Free trial pathway includes a free trial (10 videos + 100K streaming min + AI samples) with full Video Data on every session.

How do I set up alerts when QoE drops?

Configure alert thresholds in the dashboard, alerts fires when triggered. Send to PagerDuty, Slack, Opsgenie.

Does the SDK work in React Native?

Yes. Native SDKs for iOS + Android + a React Native bridge. Same SDK API across platforms.

What about HLS.js or Shaka without FastPix Player?

Native tracking. Drop in the data SDK alongside your player; events flow into Video Data with the same dimensions.

Can I segment retention by user cohort?

Yes. Set custom_1 to your cohort identifier on session init; chart retention curves segmented by cohort in the dashboard.

How do I add custom dimensions to my React app?

Pass them in the data SDK init. See the per-user analytics guide.

Can I use Video Data for research or machine learning?

Yes. Every session and event exports as structured data your team can use for BI, analytics research, and training machine-learning models such as churn or QoE prediction. For content-level metadata to ground RAG or LLMs, pair it with In-Video AI.

Video Data API

Video QoE analytics, 56 dimensions per session

FastPix Video Data tracks quality of experience across 56 dimensions on every playback session, on 17 player surfaces, in real time. View it in the FastPix dashboard, or pull every session by API into your own dashboard, warehouse, or models.

Use cases

One API for QoE, engagement, and delivery insight.

Cut buffering, startup time, and failures.

Watch the QoE families that predict whether viewers stay, buffer ratio, startup time, and playback success, and fix the worst offenders first. Sclera monitors post-migration QoE in real time.

See exactly where delivery breaks down.

Break QoE down by country, region, CDN, and ASN to find the precise place playback is slow or failing, instead of guessing from an aggregate number.

Build datasets for BI, research, and ML.

Export every session and event to your warehouse and turn raw playback data into features and benchmarks. Data teams and researchers use it for BI, analytics research, and training their own machine-learning models.

How it works

From install to insight in three steps.

TL;DR: 3 steps from install to insight

Install the SDK

Drop @fastpix/data (or the React variant) into your app with your env key. It fires on the FastPix Player or any of 17 player surfaces.

Set custom dimensions

Tag every session with viewer_user_id and custom_1 to custom_10, so you can slice charts by your own segments later.

Watch QoE in real time

Charts segment by any of 56 dimensions the moment sessions play, and raw events stream to your warehouse by webhook.

Dashboard or API

See it in the dashboard, or build your own

Every metric is visible in the FastPix dashboard the moment a session plays. Prefer your own UI? Call the Video Data API and render the same data in your product, your BI tool, or a dashboard you build.

QoE metrics

QoE scores that predict whether viewers stay.

Raw events become scored outcomes. Six metric families distill millions of playback events into one Overall Experience Score per session, and you can drill from a low score straight to the event that caused it.

Overall Experience Score per session
Stability: buffer ratio and buffer frequency
Startup: video startup time and jump latency
Render quality, playback success, and audience metrics

Player-agnostic

Works on any player you already use.

Video Data is not tied to the FastPix Player. One SDK fires the same metrics and dimensions across 17 player surfaces on web, mobile, and smart TV, so you keep your current stack and still get full QoE.

Segmentation

Slice every session by your own dimensions.

Every session carries 56 dimensions, 46 built-in plus 10 you define. Tag playback with account, plan, episode, or campaign, and segment any chart, including QoE by country, region, CDN, and ASN, to see exactly who is affected.

46 built-in dimensions: device, player, network, geo, error flags
10 custom dimensions (custom_1 to custom_10)
Break QoE down by country, region, CDN, and ASN
Segment retention by account, plan, or cohort

Warehouse and research

Export to your warehouse for session-level insight.

Stream the raw 18-event signal into ClickHouse, Snowflake, BigQuery, Redshift, or Databricks, join it with your business data, and go from a QoE number to the exact cause. The same exported data powers BI, analytics research, and machine-learning pipelines.

Alerts

Get alerted before viewers complain.

Set thresholds on any metric or cohort and Video Data fires the moment QoE drops, error rates spike, or a specific segment degrades. Route it to where your team already works.
