As for ffmpeg, probably ProWo knows the dirty tricks.

ffmpeg.exe -y -i v:\despcat1.jpg -i v:\despcat2.jpg -filter_complex "[0:v]scale=8000:-1,zoompan=z='min(zoom+0.0015,1.5)':d=417:s=578x870,setsar=1[v0]; [1:v]scale=8000:-1,zoompan=z='if(lte(zoom,1.0),1.5,max(1.021,zoom-0.0020))':d=417:s=578x870,setsar=1,fade=t=in:st=0:d=5[v1];[v0][v1]concat=n=2:v=1:a=0,format=yuv420p[v]" -c:v libx264 -map "[v]" -t 300 -threads 2 video.mp4

Use powerpoint or similar graphic tool, copy/paste/resize the pics, save the result and import the picture in your video editor

I need to embed in the commandline the overlay from my image and the background
