I have two video player (a content and a mask). When I start my project, the two video plays correctly, But, they end up desynchronizing. I would like to be able to sync them to play always at the same time.

By default, the Video Player box use the Internal Sync Mode. In this mode, the clock of the videos are synced over the RealMotion master clock. Depending on your computer's performance, the Internal Mode allows the Video Player to drift of one frame or two to have a smooth playback.

When 2 videos need to be perfectly sync, use the External Sync Mode instead. 

Go to the Properties of the Videos Player boxes -> Tab Advanced -> Sync Mode.

A Time input pin will be enabled. Connect this pin to the same box, like the Timer box.

The Video Player will then share the same clock, without drifting, and the videos will be perfectly sync.

Additionally to using an external clock like the box Timer, you can use other clocks such as MIDI Timecode or a network clocks (Network Receive) from another RealMotion instance from another computer.
Before asking a question, please make sure it is not already asked by somebody else. You can also check the Wiki for the boxes documentations and user guides.
