NVEncC64_Wrapper

Since rigaya's excellent NVEncC64 encoder unfortunately does not have an automatic cropping function, and this is only rudimentary in FFmpeg, I have extended my wrapper and added this function.

Simply calling the wrapper without parameters shows the usage:

Usage: nvencc64_wrapper <encoder(hevc)> <audio(ac3)> <quality(28)> <crop> <filter> <mode> <decoder(avhw)>

encoder = [def|hevc|he10|h264|av1]
audio   = [copy(1/2/12)|ac3(lq)|aac(lq)|eac3(lq)]
quality = [def|auto|lq|ulq|hq|uhq]
crop    = [copy|auto|c(1-6)|696|768|800|804|808|812|816|872|960|1012|1024|1036|1040|720(f/p)|1080(f/p)|2160(f/p)]
          [1440|1348|1420|1480|1500|1792|1764|1780|1788|1800]
filter  = [copy|f(1-6)|edgelevel|smooth(31/63)|nlmeans|gauss(5)|sharp|ss|denoise(hq)|artifact(hq)|superres(hq)]
          [vsr|vsrdenoise(hq)|vsrartifact(hq)]
mode    = [copy|deint|yadif(bob)|double|23fps|25fps|30fps|60fps|29fps|59fps]
          [brighter|darker|vintage|linear|tweak|HDRtoSDR(R/M/H)|dv/dolby-vision]
decoder = [def|hw|sw]

Example: nvencc64_wrapper | encoder | audio | quality | crop | filter | mode | decoder |
Example: nvencc64_wrapper   hevc      ac3
Example: nvencc64_wrapper   hevc      ac3     auto      auto
Example: nvencc64_wrapper   hevc      copy    auto      1080   vsr
Example: nvencc64_wrapper   hevc      copy    hq        1080   copy
Example: nvencc64_wrapper   hevc      copy    def       copy   copy     copy   sw

Preparations:

FFmpeg and FFprobe

Both ffmpeg applications must be present in the path:

ffmpeg.exe
ffprobe.exe

Enable automatic cropping:

You can activate auto-cropping for all files in the current path:

C:>nvencc64_wrapper.cmd hevc ac3 auto auto

The first auto parameter enables automatic quality upgrade based on the year (for older films which generally have more pronounced film grain).
The second auto parameter activates auto-cropping.

Hints:

• To display debug output and see how auto-cropping works, use: set "DEBUG_AUTOCROP=1" otherwise "DEBUG_AUTOCROP=0"
• Error handling is also implemented in exceptional cases where no valid crop values ​​could be determined.
• Completed encoded files are saved to the "_Converted" folder; the original files are not deleted.
• Files with inconsistent black borders are not encoded and are immediately moved to the "_Check" folder for further manual review.

Daily Use

To ensure that all newly copied files in the directory are always converted automatically into your desired target format — covering both video and audio — use the wrapper consistently with a minimal, generic parameter set. This approach allows the wrapper to handle quality selection, cropping, resizing, and audio handling automatically, without requiring per-file adjustments.

For example:

nvencc64_wrapper.cmd hevc ac3 auto auto

or:

nvencc64_wrapper.cmd h264 eac3 auto auto

By using these commands as your default workflow, any new files added to the directory will be processed uniformly and converted to the intended target formats with minimal manual intervention.
