FastPix vs Mux
FastPix vs Mux: the honest API-peer comparison
Mux is the longest-tenured API peer in video infrastructure with a well-known track record. FastPix differs by bundling Video Data (QoE analytics), In-Video AI (captions, NER, summary, chapters, moderation, dubbing), and Cloud Playout (24/7 linear FAST channels) at the same per-minute price as encode and delivery. Mux Data is priced per-session separately; In-Video AI is not a first-party Mux product. Here is where each fits.

What Mux calls it / what FastPix calls it
If you searched for the Mux term, here's the FastPix equivalent and why the difference matters.
| Mux term | FastPix equivalent | Why the difference matters |
|---|---|---|
| Mux Direct Upload URLs | FastPix /v1/on-demand | Direct functionality maps 1:1. Both accept a source URL and return a playback ID. |

Pricing math
What this costs at a real workload
Workload
1,000,000 source minutes encoded (up to 1080p) + delivered 5,000,000 viewer-minutes/month + 500,000 Video Data session plays/month. Storage 12 months.
Verdict
Structural difference: FastPix bundles Video Data analytics + In-Video AI at the same per-minute scope as encode + deliver; Mux Data is a separate per-session SKU on top of Mux Video. For workloads heavy on QoE analytics or AI, FastPix's bundling tends to win; for pure encode + deliver workloads, the two are close on headline rates.
FastPix
Computed from scripts/pricing_facts.py (VOD Standard 1080p): storage ~$32,256 over 12 months + streaming ~$3,395/mo at 5M viewer-min. Video Data: 500K session plays is within the 100K-1M free-to-GrowthPlan band; $0 if customer stays on Video Data Free, $299/mo on GrowthPlan. In-Video AI included as separate per-feature usage (see scripts/pricing_facts.py for rates).
Mux
[PLACEHOLDER: source against current mux.com/pricing for Mux Video per-minute encode + per-minute delivery, plus Mux Data per-session pricing. Mux Data is priced separately from encode/deliver. Verify against current Mux published rate card before publish.]

When Mux wins
When to pick Mux instead
FastPix doesn't fit every workload. Here's when Mux is the right call.
Sub-200ms real-time latency
You need true real-time, not LL-HLS .
Track-record reliance
Your buyers care that the vendor has run at scale for years.
You only need encode + delivery
You don't need In-Video AI, Cloud Playout, or first-party Player + Data bundled.
When FastPix wins
When to pick FastPix
Where FastPix specifically differs from Mux for the Mux-comparison buyer.
Video Data bundled, not separately priced
Mux Data is the mature QoE peer but is priced separately per session, scaling with viewer load on top of encode + delivery.
Cloud Playout for 24/7 linear FAST channels
Mux does not ship a first-party 24/7 linear channel scheduler. If you need FAST channels, you build it.
Bundled In-Video AI at the same per-minute price
You'd otherwise pair Mux Video with 3rd-party transcription, NER, summary, moderation, and dubbing — 4–5 separate contracts.
Migration
How a migration from Mux to FastPix looks
Use the Mux migration tool to bulk-import assets with status webhooks. Five-step shape, the tool handles re-ingest in step 3.
Inventory
List your active assets and live streams on Mux. FastPix accepts public URLs at ingest, so Mux stays the source-of-truth bucket during migration.
Provision FastPix
Create an API key, sign up for the free trial (10 videos + 100K min + AI samples). Run one POST against /v1/on-demand to validate the pipe.
Bulk re-ingest
Point the Mux migration tool at your asset catalog. The tool POSTs each asset to /v1/on-demand and fires status webhooks (queued → ready) — no scripts.
Swap players
Replace the Mux player embed with the FastPix Player SDK (Web + iOS + Android + Flutter). Pass the new playback ID; signed URLs work the same shape.
Cut over
Flip your delivery DNS / app to the FastPix playback URLs. Run both in parallel for a week, monitor, then turn Mux off.
