Re: OT - DiVX a DVD



Hola Mario!:

Yo he probado a montar DVD's desde DivX y Xvid y te cuento mi experiencia:

Para unir, retocar, recodificar videos, etc, lo mejor es usar AVIDEMUX, el primo hermano de VIRTUALDUB (si vienes de windoze te sonará fijo) o usar GMENCODER, un front-end de mencoder que funciona tb muy bien.
Por línea de comandos tienes más programas, como TRANSCODE o FFMPEG.

El caso es, una vez que tienes los mpg pasarlos a .vob y generar los .ifo y los menu para montar el dvd. Ahí tuve problemas pq al final se me desfasaba el audio en los vídeos que probé, pero el DVD (salvo ese no tan pequeño error) quedaba perfecto con los menús, los capítulos y todo lo demás.

Para ello usé los siguientes programas:

- qdvdauthor
- dvdstyler

y alguno más que no recuerdo ahora mismo.

A continuación te copy-pasteo un script para convertir videos a mpg para DVD:
Espero haberte ayudado. ;)

Hola Debianitas queria comentarles que a partir de mediados de febrero estube considerando comprarme una grabadora de DVD que si dios quiere dentro de 20 dias me la van a regalar para mis 17, les cuento que ademas hace poco caminando por el centro vi una revista (en realidad dos) q hablaba sobre grabacion de DVD's (y la otra de linux) lamentablemente la que hablaba sobre dvd's indicaba como se graban y copian dvd desde Windows, a pesar de tener un windows xp (q apesar de usarla solo para juegos, ni siquiera para mail o navegar se lleno de virus!) queria averiguar sobre la forma linuxera de hacerlo. Entonces en resumidas cuentas, estoy buscando informacion sobre grabacion de peliculas en DVD, para ser mas exacto como paso de DiVX (o XViD tambien) a DVD. Siguiendo con el mismo tema, queria preguntarles, si conocen algun programa que permita unir dos DiVX en uno, por que como sabran los fanaticos del cine a veces vienen divididas en dos archivos de aprox. 700 megas (obviamente para q entren en cd) Aclaro que no me interesa la creacion de Menús, o divicion en capitulos... solo me interesa que la calidad sea lo mas similar al DIVX original.
Espero que alguien pueda aconcejarme.
Como siempre Mil Gracias a los que leen este mensaje, y mil mas a los que responden.

Nota: Para los argentinos y mexicanos que esten interesados en adquirir la revista mandanme un mail y les mando el nombre, numero y donde comprarla por inet. No lo hago aqui por q no crea q sea bien visto.

Salu2.
