NVIDIA High speed encoding

For users with NVIDIA graphics here some news:
You really can speed-up the encoding process with ffmpeg.exe and hardware encoding! Quality is now very good.

- Copy latest ffmpeg.exe (v3.3.1 32bit Zeranoe) into B3D2MK3D's toolset folder.
- Edit the generated __ENCODE_3D:
Code:
...
ffmpeg.exe -loglevel info -i "__ENCODE_3D_MOVIE.avs" ^
-c:v h264_nvenc -profile:v high -level 4.0 ^
-maxrate 15M -bufsize 15M -b:v 15M -cq 25 ^
-g 48 -bf 3 -rc vbr -rc-lookahead 20 -spatial-aq 1 -bluray-compat 1 ^
-color_primaries bt709 -colorspace bt709 -color_trc bt709 ^
-c:a copy -frames:v nnnnn ^
-metadata Title="movietitle 3D" ^
"00xxx_3D.264" -y
The NVIDIA hw encoder cannot place the frame-packing info into the stream. But the mkv muxer makes the stereo-mode entry and it works in 3D.
You will get about 100 fps!!! (Previously only 24 fps)
Have fun!
