How can I see if a particular videowriter file is still open

I can't find a way to query the videowriter handle to see if the file is still open. I suppose I could try to write to it and see it it returns an error, but that seems clunky.

Hi Michael,
As per my understanding, you want to know how to check the status of a particular VideoWriter file.
To check the status of any file, you can use the “isopen” function.
Consider the code shown below:
x = VideoWriter(VideoFile.avi);
status = isopen(x);
where, “x” is the handle of the VideoWriter file and “status” is the output of the isopen” function. The VideoWriter file is said to be open if the value of “status” is 1 and closed if the value of “status” is 0.
For more information on “VideoWriter and isopen” functions, you can refer to the following documentation:
For “VideoWriter” function:
For “isopen” function:
