Video-converting software which is able to convert to 3D video

Hey guys,
Need some help with finding the right a video-converting software which is able to convert to 3D video, also it should allow to download, edit and remix YouTube videos. Video converter software has one main function – converting videos from one format to another. However, not all applications are created equally. I doesn’t mind to pay for the software but ofcourse if i can get it for free then that’s a bonus. Let me know which app you use in the discussions below!
