Looking at the diagram, this appears to be just an LSTM slapped on top of a CNN. If so, I'm failing to see any novelty in this approach. RNNs on top of CNNs have been used before, including for deepfake detection. See for example: https://arxiv.org/abs/1905.00582 https://arxiv.org/abs/1905.00582 The recent DeepFake Detection Challenge threw a lot of manpower at the problem earlier this year, BTW.
