L’autre soir on a vu en famille le film d’animation Coraline<\/a>. C’est un film r\u00e9alis\u00e9 en stop motion <\/a>c’est \u00e0 dire que les sc\u00e8nes sont r\u00e9alis\u00e9es avec des d\u00e9cors et des figurines qui sont anim\u00e9s image apr\u00e8s image. C’est un travail consid\u00e9rable, et le travail est remarquable.<\/p>\n

Du coup avec ma petite derni\u00e8re, \u00e7a nous a donn\u00e9 des id\u00e9es, on a r\u00e9alis\u00e9 une mini s\u00e9quence anim\u00e9e que voici.
\n<\/object>
\nIl s’agit de 37 photos mises bout \u00e0 bout apr\u00e8s avoir r\u00e9duit leur taille, l’encodage se fait avec mencoder<\/strong>. Voici le script qui permet de faire tout \u00e7a.<\/p>\n

#!\/bin\/bash
\nx=1; for i in *JPG; do counter=$(printf %03d $x);
\nln \u00ab\u00a0$i\u00a0\u00bb img\/img\u00a0\u00bb$counter\u00a0\u00bb.jpg; x=$(($x+1)); done
\ncd img
\nfor infile in *.jpg;
\ndo convert $infile -resize 640×480 -strip -quality 50 ${infile\/\/allfile\/newnames};
\ndone
\nmencoder \u00ab\u00a0mf:\/\/*.jpg\u00a0\u00bb -o movie.avi -mf fps=7 -ovc xvid -xvidencopts bitrate=1500<\/strong><\/p>\n

Quelques commentaires, admettons que vos photos soient plac\u00e9es sous \/tmp<\/strong>, il faudra pr\u00e9alablement y cr\u00e9er un r\u00e9pertoire img<\/strong>. La premi\u00e8re partie du script renomme les photos, la deuxi\u00e8me retaille les photos et les all\u00e8ge quelque peu. La derni\u00e8re partie est la commande d’encodage, \u00e0 noter qu’on peut faire varier le temps entre deux photos avec le param\u00e8tre fps<\/strong>.<\/p>\n

La prochaine fois, on s’attaque \u00e0 quelque chose de plus consistant en rajoutant une bande son.<\/p>\n","protected":false},"excerpt":{"rendered":"
