Hello Members

I am trying to Watermark my videos using Batch Script,

I Had Previously Created a .bat Files Which is almost Good

and Now i am trying to add burn subtitle cmd but Getting error When i Run Batch File

but i tried to print the final cmd, and When I Manually copy paste cmd and run then, it Worked For me

Please Guide Me the exact issue, and How to Set subtitle Path on cmd

I had added option to Crop (Top and Bottom)


Please See Below

@echo off

set %1
set /p x=crop on Top (px):
set /p y=crop on Button (px):
set /a z = x + y
echo %z%

IF NOT DEFINED Title SET "Title=encoded"

:MENU
SET /P M= Choose Quality : Press [1] :


IF %M%==1 GOTO 480

:480
echo "C:\Users\Alone\Downloads\Video\Screenshots\ffmpeg.exe" -i %1 -vf "ass=subtitle.ass, crop=w=iw:h=ih-0%z%:x=0:y=0%x%, scale=720:-4" -c:v libx264 -b:v 375k -minrate 375k -maxrate 375k -bufsize 375k -preset medium -c:a aac -b:a 48k "%~dpn1-%Title%-480p.mkv"

Hi.
I did only 1 test. It worked for me.

@echo off
:: Output goes into the \New folder.
if not exist New\ md New
Title "%~n1"

set /p x=crop on Top (px):
set /p y=crop on Button (px):
set /a z = x + y
echo %z%


:MENU
SET /P M= Choose Quality : Press [1] :

IF %M%==1 GOTO 480

:480
"C:\Users\Alone\Downloads\Video\Screenshots\ffmpeg.exe" -i "subtitle.ass" -i %1 -vf crop=w=iw:h=ih-0%z%:x=0:y=0%x%,scale=720:-4 -c:v libx264 -b:v 375k -minrate 375k -maxrate 375k -bufsize 375k -preset medium -c:a aac -b:a 48k -c:s ass "New\%~n1-encoded-480p.mkv"
Pause
exit

My preference would be:

"C:\Users\Alone\Downloads\Video\Screenshots\ffmpeg.exe" -i "subtitle.ass" -i %1 -vf crop=w=iw:h=ih-0%z%:x=0:y=0%x%,scale=720:-4 -c:v libx264 -preset medium -crf 22 -c:a aac -b:a 128k -ar 48000 -c:s ass -threads 0 "New\%~n1-480p.mkv"

If the cropping is the same for all your clips then I would set x : y only once, and then process all the clips in a folder.
This requires several changes to your batch file.

Perhaps this might be a better way to go.

Don't know if it was a finger check or not but the original example is missing the final quote after .ass

"ass=subtitle.ass, crop=w=iw:

Subtitles are fussy when i comes to double quotes, single quotes and escaping certain characters.

Hi Budman1.

Don't know if it was a finger check or not but the original example is missing the final quote after .ass

You're right, but as the whole filter string was enclosed in double quotes, it's ok. Well, that technique works here.

-vf "ass=subtitle.ass, crop=w=iw:h=ih-0%z%:x=0:y=0%x%, scale=720:-4"

I don't use the double quotes around filter strings as a rule. (As shown in the code in my previous post.)
It's just another thing for me to get wrong.

Cheers.
