Converting old videos, Part 2

In a previous post, I talked about converting 8MM video to AVI files burned onto a CD.  Many people talk about how CDs and DVDs degrade and eventually lose data.  This Christmas, I decided to copy all the AVI files off of the CDs.  Luckily, none of the files got corrupted.  I was able to convert all 22 files to MP4 files encoded in H264.  I used Ffmpeg, which used x264.  I encoded at 500kbps.  Given the 320x240 resolution and the 15 fps, I could have probably gone lower in the bps, but disk space isn't much of an issue anymore.  I converted the video from 3.8gb on 7 CDs to 2.3gb on a single Micro SD card.  Below is the command I ran to convert.  This is derived from research a buddy of mine did to get MP4 files that work on older iPhones.
