You see this in the encoding preset from Wirecast shown in figure 3. While there is a specific configuration option for profile set to high , there is no option for level. Instead, you have to set the resolution, frame rate, and data rate parameters within the restrictions set by the level.

Since the parameters are p30 , the preset conforms to level 4. The final H. Presets change the configuration of certain codec options to allow streaming producers to choose their desired tradeoff between encoding quality and complexity.

For VOD video, for example, you might choose a high-quality preset that lengthens encoding time but optimizes quality. For live video, you may have to sacrifice quality to achieve real-time encoding, and choose a lower-quality preset. While profile and levels are the same for all H. For example, figure 3 shows encoding with the x codec, which uses presets that range from Ultrafast to Placebo. Other H. Now that you know the basics, you should be able to configure your streams for optimum quality and compatibility.
