How to generate video from photos with animation on the server?

Question

ruby

Good afternoon!
It is necessary to generate a video clip from photos on the server. The principle is this: the user sends photos to the server, and the server, in turn, generates a video with animation and a sound track. So how do you make animation? There are no problems with the creation of the video itself (I use ffmpeg to glue images with audio). But different animation is needed: transitions (fade in, fade out, scroll), zooming, animation of numbers, etc. .
A good example of what should be in the end.
Thank you!

Answer 1

Smoke documentation towards imagemagick
i.e. process each frame first with it, and then collect everything with ffmpeg

Answer 2

Hmm, I would look towards some simple graphics engine (perhaps on SDL), which would be able to work without actually displaying it on the display. Those. give him images as input, he animates them in various ways and gives frames to the same ffmpeg to create a video.
