Syncaila is a standalone multi‑camera auto‑sync software that aligns audio and video across long shoots without timecode and round‑trips with major NLEs via XML, dramatically reducing manual syncing time for editors. It is widely used as an automatic waveform sync solution and is often evaluated as a PluralEyes alternative for multicam workflows on macOS and Windows.
What Syncaila is
Syncaila is professional software for video, television, and film that performs fully automatic synchronization of audio and video from multi‑camera shoots so editors can focus on creative work instead of lining up tracks by hand. Its engine uses algorithms that simulate an editor’s logic to match waveforms reliably even in complex, noisy, multi‑track timelines for robust multi‑camera audio video sync.
Who needs it
Event filmmakers, documentary teams, podcast producers, and studios handling multi‑hour, multi‑camera footage benefit from no timecode audio sync that remains stable across mixed cameras and recorders. It’s a practical Adobe Premiere Pro sync tool, Final Cut Pro XML sync utility, and DaVinci Resolve multicam sync companion when built‑in tools fall short under heavy or messy projects.
How it works
The core workflow is an XML round‑trip: export FCPXML from the NLE, let Syncaila analyze and synchronize, then bring the new XML back to the timeline for immediate editing. The process is deliberately simple—Open, Sync, Save—so teams can batch entire shooting days at once with minimal setup in a standalone sync utility.
Key capabilities
Automatic waveform sync without timecode across multi‑hour sequences and mixed devices for reliable multicam alignment.
Four chronology options to preserve clip order and context while placing even silent clips with sub‑second inaccuracy when possible.
Speed features including accelerated re‑sync, seven speed/quality modes, and resource‑efficient processing for big projects.
NLE integrations and formats
Syncaila works as a standalone application that reads and writes Final Cut Pro XML (both 7 and X), enabling an XML round‑trip workflow with Adobe Premiere Pro, Final Cut Pro, DaVinci Resolve, Vegas Pro (with conditions), and EDIUS (with limitations). This approach lets teams keep their media and bins in the NLE while offloading heavy sync logic to a dedicated tool.
Performance, reliability, and versions
Syncaila 2.7.9 was updated on October 31, 2025, reflecting active maintenance and incremental improvements to compatibility, speed, and stability for automatic waveform sync at scale. Human‑logic simulation and big‑project optimizations help maintain accuracy on multi‑hour timelines and across varied codecs and recorders, which is critical for professional turnaround times.
Limitations to consider
Syncaila accepts only FCPXML for exchange, so projects must be prepared and returned via that format for round‑tripping with supported NLEs. It does not denoise or enhance poor audio fidelity; editorial review remains essential after sync, especially in challenging recordings.
