@Michael-Guo can you share the full screen snapshot?

@dutran I have solved my problem. I think maybe there are something wrong with your train or test list. For example, suppose the video has 47 frames, 47 is not divided exactly by 16, 16*3 = 48. It misses one frame. In this situation, your train list will contain these class labels : 1 17 33. So the third clip will miss one frame No.48. Then I copy the No.47 frame as N0.48. Then features are extracted successfully.
