Hybrid encoding MP4 files with h264_nvenc?

[KirVHS]

I was thought because Hybrid has been using for MP4 files just a basic FFMPEG, and if i do this my digitizing will be much faster than basic h264

Here the settings

NVEnc --y4m -i - --fps 25.000 --codec h264 --profile high --level auto --sar 1:1 
--lookahead 16 --cbr 6600 --max-bitrate 800000 --gop-len 0 --ref 5 --bframes 3 
--direct auto --bref-mode auto --no-b-adapt --mv-precision Q-pel --cabac --deblock 
--preset default --colorrange limited --colormatrix smpte170m --colorrange limited 
--cuda-schedule sync --keyfile GENERATED_KEY_FILE --output 
"C:\Users\Griffin\AppData\Local\Temp\КудаПриводятМечты_new.264"

IGNORE RUSSIAN TITLE ITS FOR MY AUNT!

NVEnc --y4m -i - --fps 25.000 --codec h264_nvenc --profile high --level auto 
--sar 1:1 --lookahead 16 --cbr 6600 --max-bitrate 800000 --gop-len 0 --ref 5 --bframes 3 
--direct auto --bref-mode auto --no-b-adapt --mv-precision Q-pel --cabac --deblock 
--preset default --colorrange limited --colormatrix smpte170m --colorrange limited 
--cuda-schedule sync --keyfile GENERATED_KEY_FILE --output

I just saw if i disable any filtering and leave deinterlace i will get aournd 150 fps when with filters only around 30-20 fps

You are mixing:
NVEnC: https://github.com/rigaya/NVEnc/blob..._Options.en.md
and
FFMpeg: https://ffmpeg.org/ffmpeg-all.html
FFMpeg with h264_nvenc is basically the same as using NVEncC.

on Windows: Hybrid does not use FFmpeg for H.264 encoding
When using NVEncC which is hardware supported encoding, the fastest option is to:

• using NVEncC with Hardware->Only use encoder, downside is, this only works if your source can be decoded by the NVDec decoder chip. Here Everything is done by the vpu.
• next thing that is potentially faster than the next, is enabling NVEnc->Misc->Misc->DirectSythLoading, here NVEncCs own script decoder is used. Download is, that sometimes it's faster, sometimes it is not.
• next thing is simply using the default, where decoding and filtering is done by something else and NVEncC is fed with raw video.
