A Final Note

Although both VideoProc and VLC can be the FLV file converter without question, they are quite not the same. As a media converter, VLC has a rather complicated interface than VideoProc has, which is not that friendly to users who are fresh to it. Dig it deeper, VLC has many drawbacks on the 4K video playback - video in a high-res occasionally gets stuck and stutters while played in VLC, which are greatly resulted from its decoding inefficiencies and lack of hardware support. Worse than that, as an open-source media converter, VLC has many bugs and is vulnerable to viruses, which makes it easily be hijacked by hackers.

However, you will not be exposed to such awkward situations only if you are with VideoProc, in which you can play and edit up to 4K video very smoothly, no choppy playbacks, no endless hiccups but definitely strong, professional and always on-line tech support, and enjoy a wonderful experience in video editing with 100% security certified.
