I just wanted to take a little time to say THANK YOU to you and your contributors for producing such a wonderful piece of software. I am a Golf Teaching Professional and have been teaching since 1987. I started using camera acquisition and analysis software in the mid 90s. Kinovea Ver 9.5 is equal to or exceeds software that I have purchased for multiple thousands of dollars. Currently, I am using Kinovea Ver 9.5 with 3 Basler Ace USB3 cameras. I can easily go back and forth between my Left Handed and Right Handed face on cameras. Using Ver 9.5 I rarely have a crash. Most crashes occur because my USB3 Cable length is 10m and is not the fault of Kinovea. I just a wanted to let you know how much your appreciated! Again, THANK YOU SO MUCH!
