-=== h264 levels ===+When encoding, if you want to cover all your bases, there are two H.264 settings to use, and two x264 encoding arguments to pass: 
 + 
 +  * H.264 profile: high 
 +  * H.264 level: 4.1 
 +  * x264 preset: medium 
 +  * x264 CRF: 23 
 + 
 +Optionally, you can set the x264 tuning as well. Best choices are film, animation, and grain. 
 + 
 +Don't change any other settings than those. If you do, you're going down the rabbit hole.

 DVDs max out at high 3.1.  You don't need 3.2 on DVDs because that is the first level that accepts 720p. DVDs max out at high 3.1.  You don't need 3.2 on DVDs because that is the first level that accepts 720p.

 Using MP4 as the container will encode the audio to AAC by default. If using MKV, it depends on the encoder, so I'm specifying it directly. Using MP4 as the container will encode the audio to AAC by default. If using MKV, it depends on the encoder, so I'm specifying it directly.
