Animated ones/CGI can be good - watch Evolution of Verse!
..Here are some notes about video quality that I circulated internally at Oculus:
The hardware decoder on the Samsung devices can handle a lot of bit rate; I think we have successfully played back up to 80 Mb/s, but the largest image stream it can decode is 4096×2048 at 30 fps. For a monoscopic panorama that is roughly the resolution that we render synthetic game content at (but game content is 60 fps), but less than half the optimal resolution for display on the 2560×1440 displays.
There are two limits in play here — the Google video framework in Android has an (arbitrary, as for as I can tell) limit of 2048 lines high on an image, and the decoding hardware has a limit of about 240 Mpixels/s which can be flexibly divided between image size and frame rate. The optimal video stream for the current hardware would be about 6000×3000 at 60 fps in stereo, or 2160 Mpixels/s. A factor of nine over what we have now. When we get 4k displays, that will double again...

Where did you watched a high-quality version of Evolution of Verse?
Do you mean the one on Vrse? It is not CGI it is also a compressed video :?
I mean its not bad, i really like it but the quality is ridiculous compared to ORBX content for example...
..and i have to agree with the OP the quality of the 360 movies is really awful :cry:
Afaik this has something to do with the limitation of the smartphone chip and the hardware video decoder.
Here is something what Carmack has said:..Here are some notes about video quality that I circulated internally at Oculus:

So if not someone finds a tricky solution to break this decoding barrier we can only hope for a better hardware support in future devices. :geek:

You mean they got a train to drive through a lake, turn in to birds then ribbons and filmed a baby in a womb and asked it to grab hold of the camera?
No camera jiggery-pokery?
Amazing! 😄
Anyway, seemed incredibly high quality to me. Maybe i was so wowed i didn't even notice?
