Warp chroma to luma is different from deblocking or denoising chroma. What it does, using the warpsharp routine, is if there is a strong luma edge near a chroma edge it will move the chroma edge closer to the luma edge. This is occasionally useful. The downside is it can desaturate colors in dark areas. This is an option that if you have the right kind of damaged video it might be able to help.
The actual chroma deblocking is done by the calls to SmoothD2 that are made in the SmoothD2c routine.
I have added an example to
https://sites.google.com/site/jconkl...lor_deblocking that shows the same image deblocked with and without using Warp chroma to luma.
