Batch produce Image Videos with FFMpeg

[daigo99]

I've been making image videos with FFmpeg using the following:

ffmpeg -loop 1 -i Image01.jpg -i Aud01.mp3 -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest Vid01.mp4

I want to make about 60 of them using sequential image and audio files:

ffmpeg -loop 1 -i Image01.jpg -i Aud01.mp3 -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest Vid01.mp4
ffmpeg -loop 1 -i Image02.jpg -i Aud02.mp3 -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest Vid02.mp4
ffmpeg -loop 1 -i Image03.jpg -i Aud03.mp3 -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest Vid03.mp4

Is there an simple way of joining the commands so I don't have to repeat the process 60 times. I've tried && but it only outputs the final vid file.

Here's a batch file I came up with:

@echo off
SetLocal EnableDelayedExpansion

:START
Set /a COUNTER=0

:Cycle

SET COUNTER=0%COUNTER%

set PICNAME=Image%COUNTER%.jpg
set VIDNAME=Vid%COUNTER%.mp4
set AUDNAME=Aud%COUNTER%.mp3

@echo on
ffmpeg -loop 1 -i %PICNAME% -i %AUDNAME% -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest %VIDNAME%
@echo off
if errorlevel 1 goto Done

set /A COUNTER=COUNTER+1
if %COUNTER% GTR 60 goto Done
goto Cycle

:Done
pause

That will handle up to 60 files but will stop at the first missing file (or other ffmpeg error).

Here is a batch that is a little shorter that works for me. I didn't have mp3 available on short notice so I used mp2 audio. Shouldn't make a difference. Since your request was with Images starting with 1 with leading 0, I added the 'If LSS...' script to decide whether to add a zero to the filename or not.

I added the %%dpa in case the images are in a different folder than this CMD file.

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
set count=1
for %%a in (*.jpg) do (
IF !count! LSS 10 (
ffmpeg -loop 1 -i "%%~dpaimage0!count!.jpg" -i Aud0!count!.mp2 -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest Vid0!count!.mp4
) ELSE (
ffmpeg -loop 1 -i "%%~dpaimage!count!.jpg" -i Aud!count!.mp2 -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest Vid!count!.mp4
)
set /a count+=1
)

Many thanks for these. They'll make it a lot easier.
