REM IT IS [ HIGHLY RECOMMENDED ] TO RUN THIS IN A TEST FOLDER >>
REM BEFORE USING ON YOUR PERSONAL LIBRARY

REM THIS SCRIPT WILL USE [ FFmpeg.exe ] TO RECURSIVELY SEARCH >>
REM FOR A SINGLE MP4 FILE WITH SYNTAX [ <Name>.mp4 ] AND CONVERT IT TO HEVC x265
REM IT WILL SKIP OVER ANY FILENAME WITH SYNTAX [ <Name>(x265).mp4 ]

REM INFILE WILL [ NOT ] BE AFFECTED
REM OUTFILE [ WILL ] BE AFFECTED [ <Name>(x265).mp4 ]

REM IT WILL STORE THE FULL COMMAND IN TEMP FILE [ convert.bat ] >>
REM UNCOMMENT [ DEL COMMAND ] ON LINES 50-54 TO AUTO-DELETE TEMP FILE

REM USING [ -a:c aac ] CAUSES ERROR MESSAGES TO FLOOD CMD WINDOW , USE [ a:c copy ] INSTEAD

REM THIS SCRIPT [ DOES ] PASS FILE PATHS THAT HAVE AN "!" IN THEM
