Predict frames of a video using 3 newly proposed and complementary methods:
1. Multi scale cnn
2. GAN
3. Image gradient difference loss


Datasets:
-----------
* UCF101
* Sports1M


GAN
------
Generator:
   * Input: several frames of video from dataset
   * output: next frame of video

Discriminator:
   * input: original and last frame
   * output: is the last frame from dataset or generated

Problem: Still blurry on edges on moving object.
Solution: Image gradient difference loss
