question about stage1

[wangjue-wzq]

In the first stage of training, target_img, ref_img are randomly selected, face_emb is a frame from the video, the three may not be the same frame, if the training stability is guaranteed?

It could be guaranteed, because face emb only represents the facial feature, and there is only one id in the training videos.

Face_emb is fixed for a video, but the target image has different angles, expressions, and even background changes during training.
