Bonjour j'ai un probleme avec after effect car quand j'essay de importer un fichier il marque ceci :

Without any specific info about the file properties we can't tell you much. AE has never imported MKV files, anyway, so you can forget that. The rest will require more info on the specs and CoDecs used. For the MOV file start by actualyl installing Quicktime if necessary.
