Hi, I found that the 3D VAE decoder (which takes in 1 + 4 * N frames) seems to have different behavior when N is even or odd. In my testing, I am simply inputting a sequence of 1 + N * 4 frames where every frame is zeros except for the first frame. Then I pass it through the decoder and plot the original inputs vs. reconstructed output. When N is even, such as with totally 9 frames (N = 2), the result looks good:
