The new tool is rvf_mux, which combines a .rvf (the output >of halftone) with an mp3 file into a new .rvf file. You can also use this >new file again as a video input file to rvf_mux, so no need to keep the >audioless one. >Those are all command line tools, use them without parameters to get the >options. I will write better instructions later on. > >Keep the frame rates in mind, they need to stay the same across the tools. >If you want to tailor to your box, you need to know its approx.
