Did a little reading in the Vegas help file section Rendering a Stereoscopic 3D project. It says that the Sony AVC template "will will create a single AVC/H.264 file with SEI frame packing arrangement metadata to indicate stereoscopic 3D playback" .

Does this mean the MainConcept AVC template I've been using doesn't?

The MediaInfo file above was created using MainConcept AVC. I re-rendered the same project using Sony AVC and here is the resulting MediaInfo report. I'm still not recognizing anything confirming the 3D metadata is there:

I'm also trying to setup stereo for VR viewing... how to add the requested metadata?

I also have same question , if anyone find solution give me help too..

Upload video directly to YouTube using Vegas pro. File > Share Online > Upload to YouTube. Done ... it detects 3D metadata automatically

Ooops, I forgot to follow up on the original post, sorry. Adding frame-packing=3 was the solution back when YT dropped the 3D check box.

ffmpeg -i input_file.mkv -vcodec libx264 -x264opts "frame-packing=3" output_file.mp4

I have also heard YT is recognizing 3D now, without any additional metadata, but continue to add frame-packing=3 anyway.

A couple more observations...this may have changed, but I did some experiments last December and found:

It appears YouTube is only supporting side-by-side full videos now (with metadata, at the time I experimented).

Top/bottom full, with appropriate metadata' were not displayed as 3D by YouTube when I did the experiment.

I don't think YouTube is supporting side-by-side, or top/bottom half formats anymore...but don't have examples to share.

Here are my test videos from December:

Top/Bottom without metadata:



Top/Bottom with metadata (frame-packing=4):



Side-by-side full without metadata:



Side-by-side full with metadata (frame-packing=3)




 

I have been using x264VFW to render side-by-side full videos and adding the metadata in the x264 options box:



Rendering each eye to separate files and combining them into 3D, with the metadata, using FFMPEG is also an option.

I checked out the full SBS w metadata. Only anaglyph available on desktop, but in Oculus GO I was able to choose full side by side in YouTube options (full screen) via Oculus browser. Looked good! thanks

Thank you.

When YouTube stopped supporting flash, in favor of html5, all desktop viewing options were lost---it's 2D or anaglyph only, now.

I also checked these this in last week. I am using myffmpeg. I created my video using this.

now my question is , if vegas pro is unable to put metadata then why i use it for 3d editing ? while studio or other softwares is much cheaper then vegas pro.

i used x264vfw but it compress much much the video that dead the quality or may be i am not friendly to set , if you know the good setting option then give me too.

You can see my x264VFW settings in the image I posted above. For conventional, GoPro, 3D I'm rendering 1080P, side-by-side Full, with project set to "Best" video qualit



 

I keep finding the

ffmpeg -i input_file.mkv -vcodec libx264 -x264opts "frame-packing=3" output_file.mp4

suggestion on many forums online, but it isn't doing the trick. The injector works well for 360vr but I'm just trying to do regular old fashioned 1920x1080 and the injector won't do that. Any other suggestions?

When you render using Sony AVC, you need to change the Stereoscopic 3D" option in the Render As custom settings from "Use project settings" to "Side-by-Side Half." "Side-by-side (half) is the only one I've used. When you keep "Use project settings," the necessary information needed by YouTube is not included in the file, and your video will not be recognized as 3D(no matter how long you wait after uploading it). When you explicitly state the 3D side-by-side (half) format in the Render As custom settings, the necessary information is included in the file. And just because YouTube says your video is ready for viewing doesn't mean it is ready for 3D viewing. Sometimes I've had to wait another 5 to 10 minutes after the "ready for viewing" notice before it was ready for 3D viewing, and that was with a 5 second video.

AFAIK: YT is only accepting side-by-side full, with the frame-packing=3 metadata since the 3D button was deprecated.
