评论： Eliska Paulikova 2023-3-1

Hello, I use Matlab for Image analysis, so I use it for my video experiment. I have my videos on hard disk, so every time I woul like to put it to my Matlab code, I need to first move the video from hard disk to my computer, becouse directly from hard disk it is now working.

How I can do it, is there any special code for it?

Thank you so much.

@Eliska Paulikova: I guess, that the external disk is slow. Then processing a video frame by frame can take a lot of time. Copying the file with copyfile to the internal disk will take some time also, but this can be less stressing, because the data are moved in one block. But actually I assume, the total time for copying and processing is almost equal as for processing the file on the external disk.

You can use the debugger and profiler to find out, what happens inside the code and where the most time is spent.
