題目: Re: film mpeg a partir d'images

Bonjour,

Peut etre que ceci n'interesse pas grand monte mais il y a quelques
temps j'ai programmé un front-end en perl et gtk2 pour mencoder
permetant de faire ceci.
Malheureusement, je n'ai pas eu le temps de l'entretenir et je croi
bien que les options passes a mencoder par les front-end sont
maintenant depressiees.
Cepandant les modification a y apporter sont minimales et peut etre
que quelqun sera interesse par ca....

Voici a quoi ca ressemble....

Je suis tres interresse par toute contribution... (Manim est en GPL)
