[HELP] deblock with negative value

[ssdde]

i want to set deblock a negative value, eg: -3, because i see from internet that set a negative deblock value can have a sharpen effect

but in Hybrid, it can't be set to a negative value, how to do?

short: there is no such thing, you are mixing things up

longer: I think you are mixing up stuff there.
The Vapoursynth Deblock filter is a port of the Avisynth DeBlock filter: http://www.avisynth.nl/users/fizick/mvto...block.html
And there is no negative quantizer.

What you probably read is about the (inloop-)deblock options in x264 and x265.
see for example: https://x265.readthedocs.io/en/default/c...on-deblock
The values in these would be similar to the offset values of the filter above, but are also totally different since a normal deblock filter and a inloop-deblock filter are quite different.

=> those negative values you want to set are probably encoder settings.
Also those values do not have a sharpen effect on the source, they only cause the encoder not to smooth.

yes, maybe the deblock i mean is in x264 encoder. thanks

x264 Tune "grain" preset gives you --deblock -2:-2

[Selur]

yes, this modifies how the inloop deblocker works.
This is totally unrelated to the 'deblock' filter.
