Help tweak code please? (h264)

[suchanoob]

Hello, I was wondering if anyone could help tweak this h264 code? I found it on the internet and using it to go from 10bit video to 8bit. However, when I use MEdiainfo to grab the info I notice it says High@3.1. Normally I notice my files are at High@4.1. Is there a way to get this code to go from 3.1 to 4.1? Is there a difference in this? From what I read it has to do with framerates? sorry if this is a stupid question.
Thank you!!!!

@echo off
setlocal
FOR /f "delims=" %%i IN ('dir /b *.mkv') DO call :recode "%%i"
goto :done
:recode
set oldfile=%1
echo %oldfile% | find /i "[8bit]" > nul:
if not errorlevel 1 goto :eof
set newfile=%oldfile:.mkv= [8bit].mkv%
if exist %newfile% goto :eof
echo %oldfile%
set tmpfile=%oldfile:.mkv=.tmp.mkv%
if exist %tmpfile% del /f /q %tmpfile%
x264 --preset veryfast --tune animation --crf 15 -o %tmpfile% %oldfile%
mkvmerge -o %newfile% -D %oldfile% %tmpfile%
if exist %tmpfile% del /f /q %tmpfile%
goto :eof
:done
endlocal

x264 --preset veryfast --profile high --level 4.1 --tune animation --crf 15 -o %tmpfile% %oldfile%

i'm almost certain that this should do it.

Awesome! thanks for speedy reply! trying it now

Edit:
Worked like a charm!
Format : AVC
Format/Info : Advanced Video Codec
Format profile : High@L4.1

No errors at all! Thanks man.
Btw whats the difference in it? I think it was the same file size.

levels and profiles define limits of what h264 features may be used during the encode process and the proper selection should be based on what type of device(s) you anticipate the final file to be played on, most consumer level blu-ray players only support up to high@4.1 (IIRC), many "weaker" devices can't playback files encoded past basic@3.1.
