Eu estou tentando converter um monte de filmes em h.264 mp4 usando FFMPEG. Esses filmes são provenientes de várias filmadoras portáteis, como o Flip Mino HD e o Kodak ZI8. Um problema que eu estou tendo com o vídeo do ZI8 é que ele parece estar causando o FFMPEG segfault.
Aqui está o meu comando:
ffmpeg -i 'XmasSailor720p60fps.MOV' -threads 2 -acodec libfaac -ab 96kb -vcodec libx264 -vpre hq -b 500kb -s 484x272 XmasSailor.mp4
Aqui está a saída:

Eu estou querendo saber se alguém já se deparou com problemas semelhantes. Não consegui encontrar nada de útil via Google.
Outra pergunta que tenho é se alguém sabe de uma empresa que oferece suporte pago para o FFMPEG.
Obrigado pelo seu tempo.
