"The Sprite has no way to Genlock or synchronize with any external device or another Sprite at frame accuracy. You can start trigger files on 2 or more Sprites with a single pushbutton or serial control. However there are very slight differences in the internal oscillator components that allow sprites to run at slightly different frame rates. Depending on your application and video files, the frame rate difference may be acceptable and unnoticed, or may not be acceptable. The longer the video in time, the more out of step the players will become until the next trigger. You should use the same encoding parameters, CODEC, pixel size, frame rate, bit rate and etc. for all files for best results. If you want, you can get better results by comparing a few Sprites to get a better match, or altering the video on the “fast” Sprite. Adding a few duplicate frames in the video file at regular intervals will “slowdown” the progression of the scene to better match the slower Sprite." ---Quote from "DV-S1 Sprite Manual revision 4.00 for firmware version 20210416" (Source: MedeaWiz.com/downloads)
