Title: Preparing a render for Google Cardboard
Post by: rurik2000 on April 13, 2016, 08:15:12 PM
Hello

I'm prepping some renders for a Google Cardboard application.
I've been rendering files at around 5k or a bit higher, and uploaded to YouTube (after adding the metadata etc...), but the result looks very crappy in cardboard.

I'm wondering if anybody has figured out the resolution that is best for this kind of thing.  Do I need to use Big Render to make this work?  How high do I need to go?

Thanks!

do you mean the results of sending it through youtube's diseased sphincter looks crappy?  that will always be the case, and there is nothing you can do about it unfortunately.

Well I've seen plenty of 360 videos that look good both on YouTube and in Cardboard...
I feel like I must be missing something

I haven't put  any 360 videos on YouTube because of that.
I am using Kolor eyes http://www.kolor.com/kolor-eyes/#desktop (or the app) to check (on desktop or phone) and things look OK but then when you upload it to Tube it looks not nice any more.
Not sure about the encoding  - I feel like there must be one which does NOT get recoded by YouTube - which might cause the problem.

If you find the solution it would be good to read here about it!!

I have rendered three 360° videos, all in 4K. My latest one is part of this year competition: http://www.fractalforums.com/index.php?action=gallery;sa=view;id=19098
Encoding from uncompressed to H264/MP4 done via free gstreamer. You can find the commandline here: http://www.fractalforums.com/movies-showcase-%28rate-my-movie%29/t22966/

The resulting H264/MP4 were around 2GB and look cool. The re-encoded youtube version has of course much more compression artefact than my home version, but hey you can't transfer 2GB just for a 3-5 minutes clip [ today ;-) ]. The YouTube version is around 1/8 of the original size and still 300MB.

You should avoid: a lot of colors, changing colors, fast movement, too much fine detailed structures. All these things are hard work for any compression algorithm and results will be not so satisfying.
