In plain English

This is a desktop application for video editors who work with multi-person livestreams. You give it one reference VOD from Twitch or YouTube, a start and stop time within that recording, and a list of streamers who were live at the same moment. The tool then finds every collaborator's VOD covering the same real-world time window, downloads just that clip at the quality you choose, and lines all the clips up to the anchor recording. It also creates an optional timeline file you can drag straight into Adobe Premiere Pro or DaVinci Resolve. Without this tool, assembling a multi-perspective edit means hunting down each person's VOD separately, scrubbing to the right moment, trimming, and aligning everything by hand. LivestreamSync automates the whole sequence in a few clicks. The sync is based on wall-clock timestamps from each platform rather than audio-waveform matching or manual adjustment, so mixed Twitch-and-YouTube jobs line up without extra steps. YouTube start times are approximate and flagged in the interface with a tilde symbol, Twitch timestamps are precise. The app ships with ffmpeg and yt-dlp bundled inside, so nothing else needs to be installed. Each streamer's clip downloads independently, with live progress shown per lane. If a streamer was offline, deleted the VOD, or had it set to subscribers only, that person is reported with a reason and skipped without stopping the rest of the run. A visual lane chart shows how every angle aligns before you commit to downloading. The application is available as a Windows installer and a macOS disk image for Apple Silicon. It is free and open source under the MIT license. Intel Macs are not yet supported. The first launch on macOS requires a one-time security step because the app is not yet code-signed, and the README explains exactly how to allow it. For developers, the stack is Electron, React, TypeScript, and Vite, with a headless TypeScript engine that can also run from the command line. A DESIGN.md file in the repository covers the architecture and a public roadmap.

Copy-paste prompts

Prompt 1

I'm using LivestreamSync to clip a 10-minute segment from a 6-hour Twitch collab VOD. Walk me through the start/stop time format and how to add my collaborators' handles.

Prompt 2

LivestreamSync is blocked on macOS 15 Sequoia. What is the exact step to allow it to open when I can't use the right-click Open workaround?

Prompt 3

Some of my LivestreamSync clips show a tilde before the offset time. What does that mean for sync accuracy on a mixed Twitch and YouTube job?

Prompt 4

I want to import the LivestreamSync timeline file into DaVinci Resolve. What file does it export and where do I find the import option in Resolve?

Prompt 5

I'm a developer and want to add Intel Mac support to LivestreamSync. How do I run the project locally and which part of the codebase handles platform-specific builds?
