Device and method of handling video content analysis

A computing device for handling video content analysis, comprising:

• a preprocessing module, for receiving a first plurality of frames and for determining whether to delete at least one of the first plurality of frames according to an event detection, to generate a second plurality of frames according to the determination for the first plurality of frames;
• a first deep learning module, coupled to the preprocessing module, for receiving the second plurality of frames and for determining whether to delete at least one of the second plurality of frames according to a plurality of features of the second plurality of frames, to generate a third plurality of frames according to the determination for the second plurality of frames;
• and
• a second deep learning module, coupled to the first deep learning module, for receiving the third plurality of frames, to generate a plurality of prediction outputs of the third plurality of frames.
