Cette page recense les logiciels et méthodes permettant de visualiser une vidéo sous-titrée, et de sous-titrer une vidéo.
| Logiciel | Remarques | Affiche le nombre de caractères par ligne (a) | Affiche une visualisation des ondes audio (b) |
|---|---|---|---|
| Aegisub | spécialisé dans le fansub d'anime. Installable via la logithèque Ubuntu | Non | Oui |
| Gaupol subtitle editor | Installable via la logithèque Ubuntu | Oui | Non |
| Gnome-subtitles | Installable via la logithèque Ubuntu (Sauf ubuntu 18.04) | Oui | Non |
| Subtitle editor | Installable via la logithèque Ubuntu | Oui | Oui |
(a) Pratique pour savoir si la lecture du sous-titre sera trop difficile car le ratio nbre de caractère / temps est trop élevé. L'article de Wikipedia sur le sous-titrage recommande 1s pour 15 caractères.
(b) Pratique pour caler facilement et précisément le début et la fin d'un sous-titre.

J'ajoute personnellement cette astuce permettant de visualiser 2 sous titres simultanément après avoir très longuement cherché sur internet. Ceci est un script (corrigé) trouvé sur internet ayant comme nom : merge2ass.sh. Le script convertit 2 fichiers sous titre en 1 .ass (équivalent au .ssa). Votre lecteur vidéo doit être en mesure de lire ce fichier sous titre (VLC l'accepte)
La commande est la suivante :
merge2ass.sh [--help] [movie subtitle1 subtitle2] [-pm|--play-movie]
subtitle2 est le sous titre positionné en bas de la vidéo
