[HELP] i set preset "placebo" , but why the encode parameter displays "veryfast" ?

[Selur]

-> next time, spend some time, reading the tool-tips:

Preset:
Presets are ment to reduce the work needed to generate sane, efficient commandlines that do what you want.

Through a preset you select a trade off between compression efficiency and encoding speed.
Available prests are: ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow, placebo.
(medium is the default preset)

You need to press 'Apply' for a preset option to take effect.
