XVideoSharing: Quality Preset

x264 codec encoding speed depends mostly on compression Preset.
Quality is about the same when we're using CRF option.

Faster presets give you good encoding speed but larger final video files, slower presets use advances compression tech so taking much time but giving smaller video files.

Here goes Qiality presets comparison table made by us so you can choose one suitable for your needs:

Preset	Time spent	Video size	Speedup	Note
UltraFast	9.6	40.9	6.1X	Fastest. Very bad compression.
SuperFast	19.2	25.3	3.1X
VeryFast	34.3	21.4	1.7X	surprisingly smallest file size
Faster	58.9	22.7	1X	Fast & Good
Fast	77.8	23.5	0.75X
Medium	95.3	23.1	0.62X
Slow	158	22.6	0.37X	too slow, not recommended
