Realtime video mapping (plugin for Millumin)

Question

Hello,
Millumin, the software for videomapping and theaters, is proud to introduce its new After Effects plugin.
It allows you to send the output from After Effects directly to Millumin : it's a bridge between the creation (with After Effects) and the video projection onto the surface (the videomapping). No more intermediate rendering : everything is now made in real time !
Here is a tutorial, showing the process and some examples (light effect, contours, 3D, ...)

Let me know if you got a question. Philippe

You're probably going to have to make a new video composite with ffmpeg.

I'll give you some examples:
This will put images on top of your video
Top left corner
ffmpeg -i inputvideo.avi -vf "movie=watermarklogo.png [watermark]; [in][watermark] overlay=10:10 [out]" outputvideo.flv
Top right corner
ffmpeg -i inputvideo.avi -vf "movie=watermarklogo.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]" outputvideo.flv
Bottom left corner
ffmpeg -i inputvideo.avi -vf "movie=watermarklogo.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" outputvideo.flv
Bottom right corner
ffmpeg -i inputvideo.avi -vf "movie=watermarklogo.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" outputvideo.flv
Here are 3 examples for when I am overlaying subs onto a video
Overlay dvd_subs onto video (1st vid, 2nd audio, 2nd sub streams)
ffmpeg -i movie.vob -filter_complex "[0:0][0:4]overlay[0]" -map [0] -map 0:2 -c:a copy -c:v libx264 -b:v 2500k movie.avi
ffmpeg -i movie.vob -filter_complex "[0:v][0:s:1]overlay[v]" -map [v] -map 0:a:1 -c:a copy -c:v libx264 -b:v 2500k movie.avi
Overlay dvd_subs with cropping, video cropped=a, subs scaled=b, overlay (b over a)=c
ffmpeg -i video.vob -filter_complex "[0:0]crop=706:362:8:56[a];[0:4]scale=706:362[b];[a][b]overlay[c]" -map [c] -map 0:2 -c:a copy -c:v libx264 -b:v 2500k out.avi
