I extracted features from some short video files and saved each of them in separate 3d matrices. Now, how can I use SVM as classifier?

svm would not care what the origin of the data was, so you should be able to use regular svm techniques.

Could you please explain regular svm techniques?
what's your suggestion?

One option is to use CNN and LSTM.
The demo below is for video classification using machine/deep leaning method. It depends, but I think you can get better result with LSTM (Long Short Term Memory).

The image features were extracted via a pre-trained network and the time-series features were classified using LSTM (Long Short Term Memory).

if you have the bioinformatic toolbox you can use svmtrain to train your classifier and svmclassify to classify it.

thank you. I knew that commands and i used them before. but now, svmclassify give me no answer in plot.
so i think i didn't set svm properly with this data structure that explained before.
