RE: ffmpeg upgraded last month - Selur - 28.12.2024
At least QSVEncC and VCEEncC do not offer lossless encoding:
https://github.com/rigaya/QSVEnc/blob/master/QSVEncC_Options.en.md
https://github.com/rigaya/VCEEnc/blob/master/VCEEncC_Options.en.md
can't say for sure whether QSV or AMF offers some lossless intra frame encoder, but you can check their SDKs to know for sure.

how can I know which filter in hybrid vulkan supports？
RE: ffmpeg upgraded last month - Selur - 29.12.2024
https://github.com/styler00dollar/VapourSynth-RIFE-ncnn-Vulkan and the vs-mlrt filters (assuming ncnn is selected) use Vulkan, I don't think any other filters do.

Is it possible Hybird support encoding EVC/LCEVC directly at the end of this year？
RE: ffmpeg upgraded last month - Selur - 27.07.2025
Possible: Yes
Likeley: No, since afaik the only tool supporting it is xeve.
Xeve only works properly through ffmpeg (see: https://github.com/mpeg5/xeve/issues/133, also square pixels didn't work, see: https://github.com/mpeg5/xeve/issues/105) and judging by the git repository seems to be abandoned.
Also, afaik EVC/LCEVC are both not supported by any Vapoursynth source filter atm.
=> Atm. I got no plan to support EVC/LCEVC encoding.
