I am sort of new to this. I am trying to create an output video using two videos and a background image.

End result should look like this. With a bit of gap around the videos and Video A having a larger scale than Video B. And, it should end at Video A's duration. Therefore, Video B should be cropped to Video A's duration.

This is what I have managed to do so far:

Code1

ffmpeg -loop 1 -i Image.jpg -i Test1.mp4 -filter_complex "overlay=(W-w)/2:shortest=1" Output.mp4

Text

ffmpeg -i Test1.mp4 -i Test1.mp4 -filter_complex "[0:v][1:v]xstack=inputs=2:layout=0_0|w0_h0[v]" -map "[v]" -map 1:a Output.mp4

  • What are the resolutions of the image, video A and video B? How long are the videos?

  • The resolution of both the image and video B is 1280x720 and the resolution of video A is 640x360. Video A is 4min 59sec and video B is 6min 5sec. I only used video A labelled as "Test1.mp4" so far.

I managed to solve this after some pondering.

ffmpeg -loop 1 -i Image.jpg -i Test1.mp4 -i Test2.mp4 -filter_complex "[2:v]tpad=stop=-1:stop_mode=clone[v2]; [1:v]scale=640-20:360-20[a]; [v2]scale=320-20:180-20[b]; [0:v][a]overlay=10:(main_h/2)-(overlay_h/2):shortest=1[c]; [c][b]overlay=main_w-overlay_w-10:(main_h/2)-(overlay_h/2)[video]" -shortest -map "[video]" -map 1:a -vsync 2 Output.mp4
