v28 v29 18 18 19 19 === 2. Choose a preset === 20 A preset is a collection of options that will provide a certain encoding speed:compression ratio. A slower preset will provide better compression (compression is quality per filesize). General usage is to use the slowest preset that you have patience for. Current presets in descending order of speed are: `ultrafast`, `superfast`, `veryfast`, `faster`, `fast`, `medium`, `slow`, `slower`, `veryslow`, `placebo`. Ignore `placebo` as it is a joke and a waste of time (see FAQ).20 A preset is a collection of options that will provide a certain encoding speed:compression ratio.
