Zencoder encoding speed preset

Question

On the Zencoder site it's said that there are 1-5 values for the transcoding speed:

A target transcoding speed. Slower transcoding allows for more advanced file compression, while faster transcoding is possible by skipping some advanced compression features. Valid values are 1-5.

And on the ffmpegsite current presets are:

ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow and placebo
