3gp movie wizard / error occured

[Luman]

Chtěl bych se zeptat. Má někdo zkušenosti z "3gp movie wizard"? Při konvertování se mi to rozbehne a vzápětí hned spadne. V terminálu mi to pořád hlásí chybu : I/O error occured . Zdrojové video by mělo být v pořádku.
pro upřesnění vypisuji celý průběh:

Usually that means that input file is truncated and/or corrupted.
