Saved years of old Flash videos

Had a hard drive full of FLV files from the early 2000s that nothing would open. Profi PDF converted them all to MP4 and I can finally watch them again. Absolute legend of a tool.

YouTube finally accepted my uploads

Was trying to upload old FLV recordings to YouTube and kept getting rejected. Profi PDF converted them to MP4 and they went through first try. Should've found this sooner.
