Convolution2D + LSTM versus ConvLSTM2D

Are 1 and 2 same?

1. use Convolution2D layers and LSTM layers
2. Use ConvLSTM2D

If there is something difference, can you explain for me?

1. Use Convolution2D layers and LSTM layer

In this technique, you stack convolution and LSTM layers. The convolutoinal layers help you to learn the spatial features and the LSTM helps you learn the correlation in time.

2.Use ConvLSTM2D

ConvLSTM is a LSTM in which the gates (input to state and state to state transitions) are convolution operations.
