Why microlearning breaks most video stacks

Three things this stack has to solve.

Lesson-sized vertical clips

30-90s vertical, swipe-native, captioned.

Microlearning is TikTok-shaped: vertical, swipeable, captioned by default. The FastPix Player ships native 9:16 with prefetch on the next clip — built for daily-habit feed UX.

Multi-language at swipe time

AI dubbing tracks on the same clip.

Pan-Asia and India regional markets need multiple audio languages on the same clip. AI dubbing attaches alternate-language audio tracks to the same playback ID; pick locale at playback time.

Questions this team asks

Microlearning platform questions, answered.

How long should a microlearning video be?
Most microlearning apps land between 30 seconds and 7 minutes per lesson. FastPix has no enforced length cap — see the Video on Demand and Video Player product pages for endpoint-level limits.
How do I create a microlearning video on FastPix?
POST a source URL to /v1/on-demand with aspect_ratio: "9:16". You get a playback ID back, embed the player, captions are auto-generated, completion events fire as webhooks. Developer docs.
What is a microlearning video?
A microlearning video is a short, lesson-sized clip — typically 30 seconds to 7 minutes — designed for daily-habit consumption. FastPix provides the underlying primitives: VOD, vertical Player, auto-captions, per-clip analytics. Quiz overlays, spaced repetition, and gamification run in your app or via partners (Sana, Imprint).
What are the disadvantages of microlearning?
Microlearning works best for procedural and recall-heavy content. Deep conceptual learning that requires sustained context still benefits from long-form sessions. From a delivery standpoint there are no FastPix-specific tradeoffs — short clips behave the same as long ones on the platform.
How do I add AI dubbing for multi-language distribution?
Multi-language audio tracks attached to the same playback ID via In-Video AI. Pick the locale at playback time. Captions auto-generated in 30+ languages.
How do I wire completion events into my engagement engine?
Per-clip completion, skip, and replay events fire as webhooks through Video Data. Tag each lesson with custom_1: course_id and custom_2: lesson_number so you can slice retention by course or lesson in the dashboard.
How does pricing work?
Usage-based per-minute pricing across encoded, delivered, and stored minutes. Free trial covers 10 videos + 100K streaming minutes + AI samples. See full pricing.
Do you support live cohort sessions and VOD on the same API?
Yes. Live cohort sessions auto-write to VOD assets on the same playback ID — same player, same analytics, same URL before and after the session. Live Streaming.
What SDKs do you ship?
7 server SDKs (Node, Python, Java, Go, Ruby, PHP, .NET), iOS / Android / Flutter / React Native client SDKs, plus the Web Player.
How do I migrate from another provider?
See FastPix vs AWS Elemental, FastPix vs Vimeo, and FastPix vs Kaltura.
What about offline playback for low-connectivity learners?
HLS + MP4 renditions tuned for unstable 3G/4G. Your app handles download-for-offline using the MP4 rendition URL; FastPix delivers the bytes from the closest CDN POP.
