Video Upload Problem

Hello all, I have installed vshare script on http://www.freakwatchers.com recently and i manage to install the script ok (i think)! But when i try to upload video on to my site, it dont seems to work.
Every time i go to the last stept of upload, it'll redirect me back to stept 1 with no video being uploaded.

can anyone tell me what im doing wrong and what do i need to do to get this site working? plz plz plz

thank you very much for all your time reading this.

hello,

through my errors, make sure that you have ffmpeg and ffmpeg-php installed on your server and the paths are reading properly.
