I'm creating a code that starts off by reading in a video, asking the user the number of frames they would like, and creating a vector frametime = linspace(0, V.Duration, N+1). In a for loop with index 1:N, I make V.CurrentTime=frametime(k). This process, however, takes a lot more time than I thought it would. Why does it take so long? What exactly is happening when you write in a new current time?

I have the same question ! Sometime it's quick, sometime not...

I'm working with 2024b on Apple M3 ... since using Apple chip Matlab is very wrong...
