Find all video files and remove all subtitles

[Rottleve]

Hi,

I found this script for MKVToolnix (mkvmerge) and was wondering if you can do the same with HandBrake for mp4 files?

Code: Select all

@echo off
cls
set rootfolder=C:\
echo Enumerating all MKVs under %rootfolder%
echo.
for /r %rootfolder% %%a in (*.mkv) do (
    for /f %%b in ('mkvmerge -i "%%a" ^| find /c /i "subtitles"') do (
        if [%%b]==[0] (
            echo "%%a" has no subtitles
        ) else (
            echo.
            echo "%%a" has subtitles
            mkvmerge -q -o "%%~dpna (No Subs)%%~xa" -S "%%a"
            if errorlevel 1 (
                echo Warnings/errors generated during remuxing, original file not deleted
            ) else (
                del /f "%%a"
                echo Successfully remuxed to "%%~dpna (No Subs)%%~xa", original file deleted
            )
            echo.
        )
    )
)

No. HandBrake is a transcoder, not a muxer. mkvmerge is a muxer. Look up MP4Box. It is an mp4 muxer and may be able to do what you want.

Thank you for your fast answer but could you briefly explain the difference between those two? If I google "transcoder" and "muxer" I am getting flooded with technical terms and specifications...

Wikipedia dumbs it down pretty well

Thanks. Not really beginner friendly but I will learn with time...
