Maybe I miss read a step but I can't seem to figure out how to get the converter working. I have my vids saved on my desktop as FLV files and I added them to the converter but when I click on covert it says file error 1. Here are my settings.

output
MP4(MPEG-4/ACC)- video&audio
500: bitrate
25: fps
audio
auto: bitrate
auto: sampling
res
320x180
what am I doing wrong?
