As some other folks have mentioned, this program will only run one thread for video conversion.
You can work around that by control-clicking the app, selecting "Show Package Contents", then going into the "Contents" and "MacOS" folders. Double clicking the file in the MacOS folder will launch a new instance of the converter. If youre willing to split up your files, you can thus run several threads worth of conversions at the same time.
Hopefully rarevision will add this feature themselves, but this seems to work for me for now.
