I would not put Spectru512 in same basket as Intuition or NEOchrome...
Intuition is name of OS subsystem in Amiga not application software - this is library used by system.

Yes, this is quite unique for Amiga thanks to Copper. Similar concept was Display List for ANTIC on Atari 8-bit.

Nope - trailer is 24 fps (cinema film framerate), also this is STE not ST and modification of hardware are required to transfer such high amount of data from external storage - CPU is turned to DMA channel - nothing else - show us 12 - 24 fps movie with mono sound decent quality on plain ST.

Perhaps some day - currently any Amiga (ie from 1985) can provide 25 fps animation for 368x568 with stereo sound 29073 samples per second - with smart using this to be honest i don't feel pressure to push limits with slow CPU further.

AGA is capable to do even better video - with reasonable fast CPU and smart use latest video standards - for example using YCoCg space instead YCbCr thus reduce time required to color space conversion, with using some of techniques used by H.264 (integer transformations) there is a chance for compressed FMV, audio sampling rate can be higher without trickes and thus dynamic range easily can excess 90 - 100dB provide more than 16 - 18 bit quality on ordinary Paula DMA audio channel.
