can you please stop writing half words on your smartphone and write something more detailed, its impossible to know what you want, and so you want something from us its rude to write that short and uninterested, thank you.
place a storyzone in the editor and enter the video-path into videofield.
you cannot
make videos inside fpsc, you need an external program for that, dont know if you want to do reallife-video, a videocapture out of the game or a 3d-video out of a fpsc-scene imported into a 3d-prog. then simply place the video-file into videobank-folder, done. watch out wich video/audio-codecs and format you use, fpsc doesnt like most of the divx-formats. just a tip.
