Youtube 360° videos
I have been banging my head against the wall trying to render in the correct mp4 format required for injecting metadata into my video prior to upload so youtube will see it as a 360° VR video.
Youtube requires it be added to the video before upload and provides an exe to do so but nothing I do will be accepted by it.

I cannot find how to do these configuration settings in Carrara mp4 compression or any other video editor I have either,
I render to image series 1 frame per sec then rerender it in carrara at 30 fps over a much longer period as it is pretty much a static spherical render after all with just sunlight and or trees animated etc.
the frame size is far too big for virtualdub or Hitfilm as it is basically an animated panorama so going 8192x4096 pixels.

the specs needed
any suggestions? Has anyone done this? Can you do it Dart in Dogwaffle????

Wendy, have you tried Quicktime Pro? It's around $30.00 US.
I'm not sure what Closed GOP or CABAC means. You'll need to look those up. Wikipedia may be a good starting place.
QT has the ability to de-interlace the video, set the video for fast start, render out a multi-pass video, although I'm not sure about the B frame. It can also handle the variable bit rate, and custom sized video. I haven't tried as large what you want to do, so your mileage may vary. You can also convert any audio in your video to AAC.
Chroma sampling is something you'd do in your video editor if it supports it. It would be kind of a pro level feature and I'm not sure why it would really be important on youtube unless it is to correct for the their compression scheme throwing out color and other data. I'm not sure QT Pro on its own does chroma correction. Look under color correction in your video editor maybe.
The other formats I need to use the python script from github which is beyond my understanding totally
only mp4 will be accepted by the metadata exe.
I opened one in notepad and it is just text in the mp4 file but manually doing it failed too.
(I got it to work on a very lowrez mp4 redownloaded from youtube after conversion)
I get the feeling Google do not want us plebs using this 360° video feature, just the pro's as they make it so needlessly complex, just a metadata tag like side by side anaglyph videos would have been simpler.
I don't know, but I doubt it. Howler is only 32 bit and therefore doesn't particularly like large (long) videos, nor does it like them in super-high res. For example, I don't even use it for my single-image 8,000 x 4,000 images. It just doesn't like it.
Yes the technology seems beyond most home video editing programs.
Carrara was one of the few things I had that even rendered a compressed video that size.
Pinniccle studio might be ableto do it but I'm not sure.
Finally got the 360 Video Metadata app (from here https://support.google.com/youtube/answer/6178631?hl=en) to save a file, seems to have problems in Windows.
But when I ran it as Admin and opened and saved the file in the same folder as the exe, it actually saved a file. (previously it said and showed that it saved a file, but no new file existed)
My animation was an AVI file from Carrara that I converted to MP4 with Handbrake: https://handbrake.fr/
Have not tested the injected file, but it is about 500 bytes larger, so I assume that the metadata has been added.
No player or app that I have can verify the new metadata, but when comparing the files, this has been added to the new file:
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:GSpherical="http://ns.google.com/videos/1.0/spherical/"><GSpherical:Spherical>true</GSpherical:Spherical><GSpherical:Stitched>true</GSpherical:Stitched><GSpherical:StitchingSoftware>Spherical Metadata Tool</GSpherical:StitchingSoftware><GSpherical:ProjectionType>equirectangular</GSpherical:ProjectionType></rdf:SphericalVideo>
There are very few apps that can handle spherical videos because the 360 cams are very new. Besides Kolor Autopano mentioned by Google, Magix Movie Edit Pro 2016 has also added support, free trial: http://magazine.magix.com/en/360-degree-videos/
Good luck!
yes I have read that in notepad in one I added to a downloaded youtube MP4 and tried copy paste to a video file. I have tried a fair number of configurations of the mp4 encoder too
I shall download and try handbrake
here are my previous efforts, the one I uploaded then redownloaded and encoded but was only small not superHD
well my handbrake conversion came out small and black user error most likely
is the video I am trying to do
if youtube does not resize it I may be able to download it and add metadata like before but the buggers tend to,
made it CC dunno if that helps, they often add a download option if you do
Any luck?
no
