If you are looking for the cineSync 4.2.8 User Manual, it can be found here.
cineSync 5 uses our newly designed review player, which can be downloaded and installed for free on any OSX, Windows, or Linux machine.
While cineSync applications have always been free to install, cineSync 5 review player is the first version to function as a standalone player on your desktop, enabling local, frame-accurate playback and review of high-res frame sequences, OTIO and OCIO support, and more.
If you happen to be an ftrack customer also, then you use the ftrack Integration with cineSync 5. This allows versions to be added easily in cineSync review player and the notes exported back to ftrack.
Tip: If you require ShotGrid/AWS S3/AliCloud Integration, HDR support, or SDI output, you need to purchase a cineSync 5 account which will grant access to these features.
Having a cineSync 5 account will also allow you to hold a synchronized review with other users regardless if an ftrack or ShotGrid user.
