Creating H.265 AAC MP4 output

Following composition will create H.265 and AAC audio in MP4 container, with following properties:

23.976 framerate
8-bit depth
progressive field order
1920 x 1080 image size
30000 bits/s bitrate
square pixels aspect ratio
profile Main and 6.1 level
Adaptive Quantisation strength 1.0 (a value between 0.0 to 2.0 for H.264)
Closed GOP set to false (determines if B and P frames can reference frames located outside their GOP)

Audio stream in this case will be AAC LC, 44.1 kHz and 96 kbit/s bitrate.
