Videosync is currently available for Mac only. Developing for a single platform with dedicated hardware enables us to focus our efforts on making Videosync as reliable as possible.

Videosync runs on any Mac with macOS 10.11 or higher.


When working with real-time video, playing video files from a Solid State Drive (SSD) instead of a Hard Disk Drive (HDD) always results in better performance, especially when playing multiple large files simultaneously.

Graphics device

Using a dedicated graphics device significantly increases performance when using many effects or playing multiple layers of high-resolution video. Look for a dedicated graphics device in About this Mac. Note for example that the 13” MacBook Pro only has the built-in Intel Iris device, while the recent 15” machines have a dedicated device made by NVIDIA or AMD.

Dedicated graphics device

Laptop vs desktop

A Mac Pro has more graphics and CPU power than a MacBook Pro. However, we commonly perform with the latest 15” MacBook Pro. Primarily having a battery on board, in case there is a power failure, makes this the optimal choice for us.

Measuring hardware performance

When testing performance, keep an eye on the FPS indicator in the Control Window. Ideally, it should be at 60 - 59 for the smoothest results. When dropping below 30, a trained audience will start noticing that the video is choppy. To easily keep track of the current FPS while working in the Live set, the FPS can be displayed next to the Videosync icon in the menu bar. You can find the setting in Videosync’s preferences.

For more detailed info there is also an MFT (Max Frame Time) indicator. This shows you what the longest time between frames is in the last second. If this is lower than, say, 18 ms (16.6 being the theoretical frame time at 60 FPS), it means you probably had one or more frame drops in that second, meaning you may have seen a small or large hiccup, even though the average FPS is still close to 60.
