Déterminer:
- La route et la destination du/des fichiers pivot
- Quelles essences et quelles métadonnées sont importantes
- S’il existe un contrainte sur le codec
- Si le format pivot est amené à évoluer, en particulier en résolution vidéo
Rester dans des choses simples
Etre pragmatique et essayer de ré-utiliser l’existant – faire les bons
compromis
Tester l’utilisation – en particulier la compatibilité avec des systèmes tiers
