A PluralEyes alternative for Mac
PluralEyes made syncing cameras and recorders from their audio a routine step for a lot of editors. If you are looking for something that does the same job on a current Mac, Throughline syncs multicam footage from audio, needs no slate, and exports to Final Cut Pro, Premiere Pro and DaVinci Resolve.

About PluralEyes today
PluralEyes is a capable tool with a long record. For context: Maxon, which owns it, has said that PluralEyes entered limited maintenance mode in February 2023. It keeps working within the host-app and system versions it last supported, but no new enhancements are planned (Maxon’s notice). If it still does everything you need, that may be fine. If you are moving to a newer Mac or newer editing software, you may want a tool that is being actively developed.
What Throughline does for multicam sync
- Syncs from audio. No slate, no clap and no matching timecode required. Four cameras and a sound recorder can be aligned to one timeline.
- Handles messy shoots. Recordings that span several files, several recording events in one folder, and mixed frame rates.
- Shows its confidence. Every offset carries a confidence score, and a low-confidence match is flagged for you to review instead of being accepted quietly.
- Keeps the sync honest. When you denoise, transcode or burn in, the alignment is tracked. If a step cannot promise your timing survived, the sync is marked stale rather than assumed good.
Where the sync goes
Throughline exports Final Cut Pro (FCPXML), Premiere Pro (Premiere XML) and DaVinci Resolve timelines, plus EDL, per-camera video files and replaced-audio files. All audio tracks are kept.
More than sync
Throughline is one app for the work before the edit: verified card offload, on-device transcription with search across every transcript, audio cleanup, proxies, captions and a checksummed delivery manifest. Sync is one part of it. If you only want a sync tool, that may be more than you need.
Honest limits
- Your editor may already sync by waveform. Final Cut Pro, Premiere Pro and DaVinci Resolve can all sync clips by audio inside the editor. Throughline is worth a look when you want the whole shoot synced and checked before the edit, or want the alignment to survive cleanup and export.
- Mac only. macOS 14 or later, Apple silicon. There is no Windows version.
- Sync needs usable audio. Each camera has to record sound that overlaps the others. A camera that recorded silence cannot be placed by its audio.
Try it on your own footage
The 14-day free trial runs every feature on your own footage, twice, with no card. Trial exports cover the first 60 seconds, and video it writes is a 720p proof with an overlay. Run a real shoot through it and compare the result with what you use now.
