Why is the rendering process slowing right down?

Question

Hi,
I'm rendering a 4 minute clip of Pro Res LT files, there's a few effect on it but right now I'm only rendering the video at 1/4 quality.
It starts rendering fine. Then starts to slow down, and by the time it gets to about 99.35%, it takes hours to render about 0.10 %, still rendering now, has been rendering over night, and is still on 99.54 %.
Every time it renders another frame, it adds another frame onto the amount that still needs to be rendered. And the estimated amount of time left stays about the same - between 3 and 4 minutes (not true).
I'm working on a Mac, with 4GB of RAM, but also rendering to an external hard drive that should have about 400GB free.
Help please!

ah! "locate" is a command you can use to search (inside Terminal,) though you should keep in mind that its database is only updated once a week by default, however, you can update it manually whenever you like, which takes a few minutes, using (in Terminal):
sudo /usr/libexec/locate.updatedb
actually, you could always automate that by adding this to the following file: "~/.bash_profile"
[begin --don't include this line]
alias locate='if [ $((`date +%s`-`eval $(stat -s /var/db/locate.database); echo $st_mtime`)) -gt 3600 ]; then echo "locate: db is too old!">/dev/stderr; sudo /usr/libexec/locate.updatedb; fi; locate -i'
[end --that code is all you need, and it needs to be kept together, all in one line]
f.
Note: if you need to create the file, (in Terminal) use:
touch ~/.bash_profile
