I have several *.mat file which contains a Videoreader variable. In a 32 bit MATLAB it looks like this:
ans =
VideoReader with properties:
General Properties:
Name: 'mini-1-001.avi'
Path: 'W:\Mentes\WD_passport\Vekonyreteg_mozik\Mini-1'
Duration: 75.72
CurrentTime: 75.72
Tag: ''
UserData: []
Video Properties:
Width: 218
Height: 218
FrameRate: 25
BitsPerPixel: 24
VideoFormat: 'RGB24'
However in 64 bit MATLAB the same mat file this variable has the same fields but alll of them are empty!
How to recover the data?? The variable does not seem to contain any avi specific link or information. All data are pure constants.

It is not possible to read 32 bit AVI files on 64 bit MATLAB. However, workarounds are mentioned in the following answer https://www.mathworks.com/matlabcentral/answers/93175-why-am-i-unable-to-read-my-avi-file-in-64-bit-matlab-on-a-64-bit-version-of-windows-xp-windows-vist

You are mistaken. I am not speaking about the avi file. AVI file should not even be present in the folder. I am speaking about the VideoReader structure (object, variable, I do not know how to call it) which contains only numbers, cells, etc.
