The reproduce obama video looks blurry

[pensz]

env :
Ubuntu 20.04.5 LTS
libcudnn8 8.7.0.84-1+cuda11.8

I have fixed some compile error

-    fa = face_alignment.FaceAlignment(face_alignment.LandmarksType._2D, flip_input=False)
+    fa = face_alignment.FaceAlignment(face_alignment.LandmarksType.TWO_D, flip_input=False)

-    c_flags = ['-O3', '-std=c++14']
+    c_flags = ['-O3', '-std=c++17']

after i test the train result. the video looks very blurry.

when i use the pretrained model, It works fine.

Is the epoch too small?

Any suggestions would be appreciated.
