TRACK is designed for demanding users looking for a simple, efficient and versatile solution.

1. Open your videos or pictures regardless of their format

Our users work with a wide diversity of material and encoding format :

  • 16bits infrared camera
  • camera from electron and optic microscopes
  • 8, 12 and 16 bits fast imaging camera
  • webcam…

2. Live interactivity

Play or stream as fast as your computer can. Display in live parameters such as velocity, surface,…

  • flash downloading up to 10 Go file
  • smooth navigation regardless of the size of the file
