Sorry for bringing this up after such a long time, but did you ever figure out why this is the case? I tried to change normalizing LR and HR images to [-1,1] in my own implementation to maybe improve performance, but I couldn't figure out the additional changes needed to the various preprocess and deprocess calls to get consistent results.

Right now it seems like I'm having issues with this line.

TecoGAN/lib/Teco.py

Line 143 in 3a75d69

gen_pre_output_warp = preprocessLR( deprocess(gen_pre_output_warp) )

I'm thinking I can remove the preprocess/deprocess calls here, if both LR and HR footage is normalized to [-1,1], but I get weird color shifts/ flickering in the WarpPreGen tensorboard summaries, when I do.

I'm using my own paired LR data, not the default gaussian downsample from HR training data, if that changes anything.

It seems that two different normalizing strategies originate from historic reason and don't have huge impact to the performance.
The color shifts/flickering may be caused by something else, in my opinion.
