@ptrblck  It is ok for me to have batch_size=1 because I already save the previous batch before I process the second one … due to memory consumption, i cannot increase the batch_size, so I save the previous tensor manually, the most important thing for me that I want each 2nd batch is a consecutive frame to the previous one
so I can have [1_1], [1,2], [3_3], [3_4], [4_8], [4_9] ...
