the input is 96X1366, and as we multiply all the pooling param in that dimension, we get:
96=2x2x2x3x4, but in another dimension it doesn't fit at all: 4x4x4x5x4=1280,shouldn't it be1366?
You're correct. A better way would be either used shorter clips from the beginning - or pad zeros to use all 1366 frames. The current setting is chosen just because it was convenient to do so.
