Try this:
[y,Fs] = audioread(filename);
audiowrite('outputfile.WAV',y,Fs);
File formats of .avi and .MOV are not mentioned among the accepted input file formats of audioread's documentation ( https://www.mathworks.com/help/matlab/ref/audioread.html#btiabil-1-dataType ), but I tried them in R2020 and they work with this code.

This does not work in r2018a:
>> [input_file, Fs] = audioread('2020-11-28 13-44-42.mp4','native');
Error using audioread (line 88)
The file type is not supported

R2018a documents .mp4 support; https://www.mathworks.com/help/releases/R2018a/matlab/ref/audioread.html -- though you might need to install a codec package .
