The resulting size will necessarily have some quality loss, and the resulting file size will depend greatly on the quality of your encoder, not just on your settings for codec choice and options. What you really want to do is repackage the audio and video streams from all your files into a single container file. Back when I was poking "simple" things like this, I used 'avidemux'. That was ages ago, and on Ubuntu, but it might work for you. You'd want to use 'copy' for your audio and video selection, to avoid any transcoding. On Ubuntu, I usually had difficulties(read: crashes) with avidemux when some tool or library it wanted wasn't installed--it wasn't smart enough to remove those options from its menus if those options weren't present. I haven't tried it on gentoo; it's plausible someone fixed that either upstream or as part of some USE flag awareness in the past couple years. I expect there are ways to do the exact same thing on the command line using ffmpeg, but I'm less familiar with that tool.
