• FFMPEG - Instructional video combining letters to a background to form a word

  6 juin 2020, par Knide

  I'm trying to help with coding a FREE site for instructional video for kids on how to write in australian. To help with the current pandemic that we are experiencing right now.

  



  Anyway, I'm new to ffmpeg and would like to do the letter combinations programatically using it.

  



  So basically I have a form where teachers or parents can enter a word, and I have video instructions for each letter, and would combine them to form the word.

  



  Example : Dog

  



  This is the background :
https://drive.google.com/file/d/1Ds1sRKQ98c5d31dI6qkqTrp1U9f89nv2/view?usp=sharing

  



  These are the letters :

  



  D - https://drive.google.com/file/d/1DHa1sZ7mklY1p3lquD8h5kTbXaZmtB_z/view?usp=sharing

  



  o - https://drive.google.com/file/d/1Ytwq_3l7x0vRDMEpZpmFjT9QNICYWH_D/view?usp=sharing

  



  g - https://drive.google.com/file/d/16jcOsrSbMSbsk2vsqeMXv9Cc4Uss7qtj/view?usp=sharing

  



  And the output would become :
https://drive.google.com/file/d/1RT38IOwXsL9kW9mj41KrxwfI_kdZy45j/view?usp=sharing

  



  If you could help with supplying what ffmpeg code we could use to have the output video, that would be great.
