So I got a few shows I want to put onto a Dual-Layered DVD so that I can hopefully keep the HD quality footage as I add audio from a different source. What is the best way to render the raw m2ts file and keep the HD quality while rendering? I have tried numerous ways and they seem to all be wrong as my footage when I render it comes out to be like 80 GB! like 4 times the size of what the original file is? just a bit confused.
