AviSynth+ 16-bit Overlay function?

[TomArrow]

I've been using AviSynth+ for a while now and really appreciate the deep color features.

The documentation of the Overlay filter states that it only supports 8 bit, with a note for AVS+ that says "TODO".

Is the documentation just outdated or does it really just support 8 bit? That would be quite a shame, since its such a general purpose filter.

I understand that the Layer filter does support RGB64, but it doesn't have all the same transfer modes as Overlay, for example softlight.

Yeah, documentation is not finished. Mentioning "shame" is a bit strong though.
EDIT: doc updated

10-16 bit formats are supported. Mode "blend" works also for 32 bits.

Besides old packed RGB formats, planar RGB is supported.
RGB is not converted to YUV 4:4:4 for mode "blend"
YUV 420 or 422 are not converted to 444 for "blend", "luma" and "chroma"

Thanks for taking the time to write that up.

That's very good news. Mostly interested in the softlight mode and general purpose overlaying without any mode myself.

Pinterf, I dont think that TomArrow meant the word shame to be taken in the context that you took it to be.

From my WordWeb hotkey dictionary

Noun: Shame sheym

1) A state of dishonour
"one mistake brought shame to all his family"

2) An unfortunate development

I think TomArrow meant '2' and you read '1'.

EDIT: 2) is used very frequently by English speakers(to mean unfortunate, eg its a shame),
1) more rarely used (eg shame on you).
EDIT: Missed out some additional meanings and verbs for the word 'Shame'.

EDIT: "Its a pity", can also be used to mean unfortunate, and could possibly also be misconstrued.

Yep, that's what I meant. I didn't mean to put shame on anybody.

Thank you for the clarification, I usually release my negative thoughts in five minutes at most; it's a shame I didn't learn English idioms properly

I see what you did there
