I use it like this:
clear
pathname = uigetdir()
[file,pathname]=uigetfile(pathname);
filename=strcat(pathname,file);
v = VideoReader(filename);
So I am selecting a file that exists, This seems to be independent of the video file I try to read, as a matter of fact it doesn matter if the file exist or not.
I also get the same error when using mmfileinfo

Can you show the value of filename before it is inputted in VideoReader ?

Sure!
%% Select video file
% Initialize variables.
clear
pathname = uigetdir()
[file,pathname]=uigetfile(pathname);
filename=strcat(pathname,file);
disp(filename);
%% read video
v = VideoReader(filename);
The output from this:
>> filename
filename =
'C:\Users\nleoni\Documents\microfluidics\helios\MI1\videos\20230918R2493Unit1038_50s.mp4'
pathname =
'C:\Users\nleoni\Documents\microfluidics\helios\MI1\videos'
C:\Users\nleoni\Documents\microfluidics\helios\MI1\videos\20230918R2493Unit1038_50s.mp4
Error using VideoReader/initReader
Too many output arguments.
Error in audiovideo.internal.IVideoReader (line 136)
initReader(obj, fileName, currentTime);
Error in VideoReader (line 104)

Error in videoReaderTest (line 10)
v = VideoReader(filename);

Solved,
Hopefully no one spent to much time on this. There must have been another function with a similar name in the path, not sure but maybe from some older work I had done....
After moving the script to a different directory and narrowing the scope of the path it actually works
