How to restore .mat formatted data to the original .avi or .mp4 video files？

[Harry2345]

Thank you very much for providing the dataset. How can I restore .mat formatted data to the original .avi or .mp4 video files?

If you already downloaded MMPD dataset with agreement, you can easily read it by the following code:

import scipy.io as sio
f = sio.loadmat('p1_0.mat')
print(f.keys())

Then you can get the video (shape: [t, w, h, c]) and write it as avi or mp4 file. Please note that incorrect encode method may damage the quality of the dataset if you want to change it back to video.

What encoding should I use for the MMPD dataset to ensure no loss?

Could you share your motivation to get the mp4/avi so that we could offer better suggestions?
