Length of Training data

[sstzal]

Hi，
I have a question about the training data. Looking forward to your reply.

How many frames were used in training a head avatar?
I have conducted some experiments based on the original GS and found that using more frames for training leads to worse results. Do you have any suggestions as to why this is happening?

For head avatars, the last 350 frames were used for training and the rest are for training.
What do you mean by "the original GS". The original GS is for static scene, and do not apply for moving heads here.

@sstzal Hi, I wonder how much time is needed to train such a head avatar.
