Would it be possible to render a video from projected W?

[georgeguida]

I would like to generate a video from a projected w vector and specify the number of frames between this interpolation. The current image generator permits the option to ==projected-w, however, this does not seem possible for video. Is this currently possible?

Describe the solution you'd like
Project images as npz file (vs npy) -> combine multiple vectors into a single npz file -> generate interpolation video between projected images.

Describe alternatives you've considered
Resembles this generator - https://github.com/dvschultz/stylegan2-ada-pytorch/blob/main/generate.py, or the colab : https://colab.research.google.com/github/dvschultz/stylegan2-ada-pytorch/blob/main/SG2_ADA_PyTorch.ipynb#scrollTo=4cgezYN8Dsyh

@ !python generate.py --process=interpolation --interpolation=linear --easing=easeInOutQuad --space=w --network=/content/ladiesblack.pkl --outdir=/content/combined-proj/ --projected-w=/content/npz/combined.npz --frames=120

Amazing set of features! Thank you @PDillis

It can be done, but have you also tried using that file in this repository directly (changing its name and just removing everything else)? If it doesn't run, what errors do you get? Will look into it still!

Tested it out, however stylegan2 ada pytorch and stylegan 3 .pkl files are different

Input :
!python generate.py --process=interpolation --interpolation=linear
--easing=easeInOutQuad --space=w
--network=/notebooks/training-runs/00007-stylegan3-t-dataset_dalle-gpus2-batch32-gamma8/network-snapshot-000600.pkl
--outdir=/notebooks/out_generator
--projected-w=/notebooks/projector/00000-projection-w-wavgstart-sgan2/projected_wavg_final.npy
--frames=200

Error:
/notebooks/stylegan3-fun/generate.py:59: SyntaxWarning: "is not" with a literal. Did you mean "!="?

Thanks for your response 👍
