One of the presets has "h264 in MP4" that already has all the options to

create such a file. If you want to render animations for platforms such as

YouTube, an MP4 file with h264 is a great choice.

You might want to change a few details about the video to tweak the

quality. For instance, change the Output quality from "Medium quality" to

"High quality" to get much better quality for animation rendering. Those

settings will improve aspects like video bitrate.

That keeps your video file with the highest possible quality and will most

likely generate a large file. In the audio field, you will notice that it shows

the option "No audio." Because our animation's frames from the 3D

Viewport doesn't feature any audio, you should keep the option as "No

audio" (Figure 8.12).

You can add audio for any animation later in the Video Sequencer Editor

and use those settings to control both format and quality for any audio

data.
