How can I make a slideshow of images into a video with each image having a specific length of frames to be shown ?
24 novembre 2013, par jettRight now I am using something like this to create a video from a selection of images :
avconv -i input%05d.png -r 24 -vsync cfr -c:v libx264 output.mp4But I want each picture to have a separate amount of time spent on it, so if I have 5 images I might want :
[10frames, 40frames, 5frames, 80frames, 10frames]To be specified. The only thing I could find that may be a solution is to create five separate videos- set the length then merge them together, is this my only choice here ?
