Stream movie to mp4 video

Hi, I would like to export an MP4 video (H.264, AAC). I have downloaded a movie from YouTube, and I would like to perform some quantification on it. So i want to stream the movie to MP4 for better edition, my friend asked me to download a program here however, it always asks me to set some parameters, actually I know a little about these parameters like frame rate, I wanna know is imagej helpful or not? or better product recommend? thanks


Perhaps take a look at this plugin:
