I just read the "Tips for VR porn producers" and I think its really nice that you guys are doing something like that, so thumbs up. But I found the infos about psvr a bit lacking and...they have some issues, and since I know its hard to get infos on how to encode for psvr I thought I might help out here.
This could also be interesting for non porn producers.

So... for starters it is allways a good idea to have a look at the official littlstar specs here: http://docs.littlstar.com/display/CG/PlayStation+VR+Video+Sideloading
Its a good starting point and you cant make anything wrong when you follow their instructions. But there are some issues:

First of all I should mention that littlstar has (other than mentioned) problems with 60fps. It is better to encode using 59.94fps. Lower fps are, of course possible of course, but it wont look good or feel as realistic.
Second, a bitrate of 20Mbps might work (on a pro), but only in short videos with low resolution. The longer the video and the higher the resolution, the worse it gets (slower playback, high latency, etc).
For videos from ~20 minutes and more its best to choose something from 13 to 15Mbps, depending on the resolution. For example: for 4,096×2,160 its still too high.
Coming to the resolution:
4096x2160 might be possible with the pro, but you should consider the low bitrate you need to aply for this to work...
The best resolution (for the pro) for sbs videos ranges between 3200x1600 and 3840x1920 @59.94fps and 15Mbps.
For tb it should be even lower: from 2160x2160 to 2560x2560 @59.94fps and 15Mbps
Half the size for the non pro.
And at last, the video profile MUST be high, using main profile results in a black screen and only audio playing or even freeze. Aditionally everything between 4.1 and 5.2 should work fine.

Well, thats that for now.
I should mention that the infos I added here are recommendations, I'm no publisher or professional. All I know comes from personal experience and testing.
English is not my native language, so ther might be some errors :/

It would be nice to get some feedback to further improve the results 😉
