5. x264 Presets Demo. Ultrafast vs Slow

In this lesson, we compare x264 encoder presets.

Encoder presets change how much time the encoder spends searching for compression efficiency. Faster presets encode quickly, while slower presets may produce better compression at the cost of time.

You will learn:
1. What x264 presets control.
2. Why ultrafast and slow can produce different file sizes.
3. How encoding speed and compression efficiency trade off.
