# Fonderie
Avec toutes ces fonctions disponibles et `grabvidseq`, nous
savons faire des images **floues***. L'étape suivante, les plus
pervers d'entre vous le savent déja, est celle de la création
de **films flous**.
## fonderie
Le programme principal, utilisé à partir de la ligne de commande
avec une foule d'options aux mnémoniques abscons.
Rassurez-vous, en général ils sont wrappables dans des scripts
shell. Il est même possible un jour qu'ils puissent lire des
paramètres dans `$(env)`.
## crapulator
C'est dans ce module qu'est codé le moteur de filtrage, utilisé
aussi bien en entrée qu'en sortie.
