ffmpeg padding doesn't scale when changing resolution
5 mars 2023, par MartinI have a ffmpeg command which takes a bunch of audio files, 3 image files, and renders a video with them.


Image Input Dimmensions :


- 

- 1_front.jpg 600w x 593h
- 2_back.jpg 600w x 466h
- 3_cd.jpg 600w x 598h








The video has a resolution of w=600 h=593, which is the resolution of the first img.


Here's the full command


ffmpeg
 -r 2 -i "E:\filepath\10. Deejay Punk-Roc - Knock 'em All The Way Out.aiff"
 -r 2 -i "E:\filepath\11. Deejay Punk-Roc - Spring Break.aiff" -r 2 -i "E:\filepath\12. Deejay Punk-Roc - Fat Gold Chain.aiff" 
 -r 2 -i "E:\filepath\1_front.jpg" -r 2 -i "E:\filepath\2_back.jpg" -r 2 -i "E:\filepath\3_cd.jpg" 
 
 -filter_complex 
 "
 [0:a][1:a][2:a]concat=n=3:v=0:a=1[a]; 
 
 [3:v]scale=w=600:h=593,setsar=1,loop=580.03:580.03[v3]; 

 [4:v]pad=600:593:0:63:color=pink,setsar=1,loop=580.03:580.03[v4];
 
 [5:v]scale=w=600:h=593,setsar=1,loop=580.03:580.03[v5];
 
 [v3][v4][v5]concat=n=3:v=1:a=0,pad=ceil(iw/2)*2:ceil(ih/2)*2[v]"
 
 -map "[v]" -map "[a]" -c:a pcm_s32le -c:v libx264 -bufsize 3M -crf 18 -pix_fmt yuv420p -tune stillimage -t 870.04 
 "E:\filepath\vidOutPutCorrect.mkv"




For filter_complex this second part will add padding to the second image so that it does not get stretched or cropped.


[4:v]pad=600:593:0:63:color=pink,setsar=1,loop=580.03:580.03[v4];



Specifically this part


pad=600:593:0:63:color=pink



Which I understand means w=600 and h=593, but i dont know that the last part
0:63
means.

You can see the output has the pink padding correctly



but i want to render the video with a resolution of w=1920 h=1898 instead of w=600 h=593.


So i update the command to have this new resolution :


ffmpeg -r 2 -i "E:\filepath\10. Deejay Punk-Roc - Knock 'em All The Way Out.aiff" -r 2 -i "E:\filepath\11. Deejay Punk-Roc - Spring Break.aiff" -r 2 -i "E:\filepath\12. Deejay Punk-Roc - Fat Gold Chain.aiff" -r 2 -i "E:\filepath\1_front.jpg" -r 2 -i "E:\filepath\2_back.jpg" -r 2 -i "E:\filepath\3_cd.jpg" 

-filter_complex "
[0:a][1:a][2:a]concat=n=3:v=0:a=1[a];

[3:v]scale=w=1920:h=1898,setsar=1,loop=580.03:580.03[v3];

[4:v]pad=1920:1898:0:63:color=pink,setsar=1,loop=580.03:580.03[v4];

[5:v]scale=w=1920:h=1898,setsar=1,loop=580.03:580.03[v5];

[v3][v4][v5]concat=n=3:v=1:a=0,pad=ceil(iw/2)*2:ceil(ih/2)*2[v]"

 -map "[v]" -map "[a]" -c:a pcm_s32le -c:v libx264 -bufsize 3M -crf 18 -pix_fmt yuv420p -tune stillimage -t 870.04 "E:\filepath\slidet.mkv"



my video does in fact now have a resolution of 1920x1798 which is great, but the 2nd image padding portion has the image super small and in a corner




So this line works :


pad=600:593:0:63:color=pink



but with a different resolution is looks bad with the image in the top left corner


pad=1920:1898:0:63:color=pink



What do I need to change
0:63
to in order to have the image be centered ?
