About video prediction

[nameless-mqc]

Hi. I want to use convlstm to do video prediction(N to 1). How can I stack a few convlstm layers and pass the outputs to a conv2d layer? In keras, I can stack a few convlstm2d and use return_sequences=False in the last one to make sure the dimension is right, but I don't know how to use this convlstmcell, should I use tf.contrib.rnn.MultiRNNCell?
