ArcLight vs Ecamm
ArcLight is a Mac app that turns slides into live video; Ecamm is a Mac app for streaming live to social platforms. Both are Mac-native, and both can morph a layout between scenes: Ecamm with Live Motion, ArcLight with Magic Move. Ecamm is ahead on streaming, with multistreaming over RTMP, browser-link guests, and ISO recording and NDI on its Pro plan. ArcLight is ahead if you think in slides: the whole show is authored as a deck with a transition on every slide, builds, a presenter view with notes and a voice-tracked teleprompter. Ecamm is a subscription at $16 or $32 a month, billed annually. ArcLight is $49 a year after a 30-day trial.

Same platform, different starting point
Ecamm (formerly Ecamm Live) is the leading Mac-native live-streaming app. You save scenes, lay overlays over the camera, and go live to YouTube, Facebook, Instagram, X, Twitch, Amazon Live or custom RTMP, several at once. It can present a PDF or a Keynote or PowerPoint deck alongside your camera. Live Motion, added in version 4.4, animates changes in overlay size, position, rotation and border between scenes.
ArcLight makes the deck the show. Cameras, screens, windows, video and titles sit on slides, and each slide has its own transition. Magic Move morphs every layer that appears on both slides, including crop and masks. Builds bring layers in and out on a click. A presenter view shows the current and next slide, notes and timers, and the teleprompter can take slides live at cues in your script.

Choose ArcLight if
you think in slides: a whole show authored as a deck, a transition on every slide, builds, a presenter view with notes, a voice-tracked teleprompter, and guided per-camera color with scopes. You'd pay once instead of a subscription.
