Amazon Interactive Video Service vs OBS 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.

OBS Studio is free, open-source software for video recording and live streaming on Windows, macOS, and Linux. It captures and mixes video and audio from windows, images, text, browser windows, webcams, and capture cards. Users can arrange unlimited scenes, switch with customizable transitions, and preview scenes and sources in Studio Mode before going live. Multiview can monitor eight scenes. The audio mixer has per-source filters, with VST plugin support, and hotkeys cover many recording and streaming actions. An API, native plugins, and Lua or Python scripts provide ways to extend the software. OBS supports streaming platforms including Twitch and YouTube, and streams connect directly from a user’s computer to the service. It is distributed under GPLv2 and may be used commercially subject to the license terms. The download page lists Windows 10 and 11 support, macOS 13.0 or newer, and Linux distribution through Flathub or an Ubuntu 24.04-or-newer PPA. The listed plan costs nothing, with no watermarks or usage limitations.
