Here's the basis for what I'm trying to do:

fname = inputdlg('Enter Filename without extension','Input');
name = strcat(fname,'.avi');
movie2avi(handles.movie, name,'fps',handles.fps,...
              'compression','None')

This gives an error: "Invalid input arguments. Second input argument must be a filename." Is this a limitation of matlab that the argument has to be a string, and can't be a variable pointing to a string? If so, is there a way around this?

Thanks, Neil

Maybe try this:

fname = inputdlg('Enter Filename without extension','Input');
name = strcat(fname,'.avi');
movie2avi(handles.movie, name{1},'fps',handles.fps,...
              'compression','None')
