What must be the size of each frame of the video? Or what must be the dimensions of a batch input?

Hello, The default sample size is 112 x 112 (check opts.py flag --sample_size). The size of the batch input depends on the ram capacity, if using gpu, depends on your gpu ram capacity. The temporal window is fixed on 16 frames, so every batch will have this format: batch_size x 16 (frames) x 3 channels (RGB) x 112 x 112.
