Convertendo música e vídeo no Linux…

24 de July de 2007 às 9:47 pm

Acabei de descobrir um programinha que eu já vinha buscando há algum tempo. É o Multimedia Converter para Linux. Ele converte músicas e vídeos entre muitos e diferentes formatos (AVI, DVD, VCD, WMV, MPEG, MP4, FLV, ASF, MOV, 3GP, …) de uma forma simples.

O programa é somente uma interface gráfica para o ffmpeg mas quebra o galho evitando a linha de comando. :)

Senti falta de um pouco mais de configuração para poder, por exemplo, reduzir a resolução do vídeo. Bem… nem tudo é perfeito.

Testei fazendo uma conversão de AVI para VCD e funcionou perfeitamente.

Se você está interessado, o artigo “Multimedia Converter: Convertendo qualquer formato no Linux!” explica como instalar o programa na sua distro.
