What to know before converting WebM to MP4

Formats acceptés
Video uploads: MP4, AVI, MOV, FLV, MKV, WebM, 3GP, MPEG, GIF, WMV, and TS files up to 500 MB.
Sortie

Règle de qualité
La conversion modifie le format et la compatibilité. Elle ne restaure pas la qualité, la résolution ou les détails audio absents du fichier d'origine.
