При пресетах Medium и ниже, ничего не обрезается.
Больше всего режет на таких вот небольших роликах.

Mediacoder Premium 0.8.36.5757. На 2-х компах (win2003 и 2008r2), разные версии (х86 и х64). Пробовал x264core148 и последний mkvtoolnix - все тоже самое.

Кто виноват? И главное, как поправить без перекодировки? Ибо уже сконвертил более 100 роликов.
