.input('./_animation/static1.png').inputFPS(1)
.input('./_animation/static2.png').inputFPS(1)

.save('./public/_ugc/' + new Date() + '.mp4');I would like to create a video which combining from 4 sources, i.e. overlay1 sequences, overlay2 sequences and two static images. However, it is now always shows only one of the sources only. How to combine them in each of the frame ?
