Amazon Interactive Video Service vs PRISM Live Studio

Amazon Interactive Video Service is a paid managed service for delivering live video through low-latency or real-time streams. AWS lists real-time latency below 300 milliseconds and low-latency delivery at 3–5 seconds. Real-time streaming accepts RTMPS and WHIP input with WebRTC output; low-latency streaming accepts RTMPS and SRT input with HLS output. Chat and timed-metadata APIs support features such as polls, graphics, and synchronized elements. A stage allows multiple hosts to exchange audio and video, then broadcast to an IVS channel. Standard and advanced channels can transcode video into multiple resolutions and bitrates. Streams can be recorded to customer-owned Amazon S3 for archiving and on-demand playback, with MediaConvert support. AWS says channels can serve millions of concurrent viewers. SDKs cover web, iOS, and Android. Listed input plans start at $0.20 a month, and a Free Tier is available for new AWS customers.

PRISM Live Studio lets creators broadcast live, record video and take photos using effects and media such as stickers, images and music. Desktop apps for macOS and Windows provide customizable scenes, media and game sources, drawing mode, free widgets and in-app live chat; the listed maximum resolution is 4K. Desktop users can stream to one channel on the free plan or up to six with PRISM Plus, which costs $9.99 a month. Mobile features include screencasting, voice-responsive VTuber avatars, viewer chat, camera effects, animated text and overlays. The mobile product page lists up to six simultaneous streams at 1080p and 60 fps. Named destinations include YouTube, Facebook, CHZZK, NAVER Shopping Live, BAND, NAVER TV, SOOP, Twitch and custom RTMP URLs. PRISM Lens adds virtual backgrounds and face retouch effects and can work as a virtual camera in Zoom and other programs. The free PRISM Basic plan includes dual output to two channels and 30 minutes of 3D VTuber face tracking, with ads, watermarks and outros displayed.
