Hi Franz,
Many thanks for your answer!!!
> I appreciate your enthusiastic work on such a complex project like
writing a video codec
Yes, for now the NHW codec is more an image codec actually, would need to
add inter frame mecanism (motion estimation, motion compensation) to the
codec to become a real video codec.The NHW Project is more a
proof-of-concept in its currents state to validate for example the wavelet
transform, the multistage residual coding, the compression schemes, and
other processings, that are new and royalty-free.Do you think I can have a
freelance contract with minimum salary to do this, because completing and
finishing the codec will require me full-time work.

Would be just great to find a use-case for the NHW codec! If you and/or
other Xiph community members would know such potential use-case,
niche-case, do not hesitate to let me know!

Yes the NHW Project lacks a good website with good visuals.But I won't be
able to do this website alone...
As you suggest, maybe Xiph.org wants to host and help with the NHW Project
website? -Would be just great!-
Again thank you very much for your kind help, it is much appreciated.
Kind regards,
Raphael
