If it's possible to upload full SBS to YT adding yt3D:aspect=15.99:9 in the tagbox the quality of our 3D videos would be a lot better than 3D SBS half width. This is a test with
1920x1080p SBS Full to see if it works... use 2160p as resolution to wach..
EDIT 14-06-26: It plays fine in Firefox and Safari but I can't get it to work in Chrome...in Chrome it shows as SBS full only...and as allways, I can't change the 3D option...maby I'm doing something wrong...if you know how to change options in Chrome, please inform me.
In Firefox YouTube recognize the video as 4K (wich was my intention), you can choose 2160p as quality and it plays in perfect 16:9 in any 3D mode you'd like to use.
So, uploading Full SBS gives you a much better quality video even after YT convertion - if you use Firefox or Safari as webbrowser.
Check out the difference by changing between 1080p and 2160p...1080 is "what you,ll get" with SBShalf (but better...) and 2160 is what you get with SBSFull...
And please try this for yourself...it's fun :)
