[FFmpeg-user] Marge 2 videos (side by side)

[Masud Rana]

Dear support,
I am using the following command to marge 2 videos side by side.
ffmpeg -i  *left.mp4* -i  *right.mp4* -filter_complex
"[0:v:0]pad=iw*2:ih[bg]; [bg][1:v:0]overlay=w"
*output.mp4*

Now my question is, how i can give a 10px white border or
space(horizontaly) in between 2 videos?


Please help me, would be appreciated.




*Best Regards,*
