Yellowstone Epic in #3D

640,000 years in the making – Yellowstone Epic in 3D! Part 1 (4 minutes)

Photographed in 2012 but delayed due to *numerous* technical difficulties with video editing software that destroyed the project three times! Even in this final version, Sony Vegas Pro is unable to output standard side-by-side 3D without scrambling the video!

Photographed using dual Lumix GH-2 cameras and dual Canon HF M100 camcorders. Music licensed from The Music Bakery.

World’s First 4K 3D Civil War Battle videos

I realized last night that the 4K 3D videos I posted on Youtube are the world’s first ever Civil War era battle re-enactments posted online in 4K 3D format. Kind of cool.

The videos were created using dual Lumix GH-2 cameras, each shooting a 1920×1080/30p video stream.

These were edited and mastered in Sony Vegas Pro and output as full width side by side videos – meaning 3840 pixels wide by 1080 high.

This is then uploaded to Youtube with several “tags” set to tell Youtube how to encode the video properly. When viewed on Youtube, two new viewing resolutions appear: 1440 HD and 2160 4K. Even if you only have a typical 2K monitor, either of the higher resolutions looks much, much cleaner in 3D!

ImportantThis remains experimental! I can only view the videos in correct format using Firefox. Chrome tells me I do not have HTML5 compliant hardware. I could play all but one video on an LG 3D TV using the LG Youtube app. However, when I played the videos on the same TV using a Sony BluRay player’s Youtube app, the videos have the wrong aspect ratio (3840×1080 instead of 1920×1080). A separate video I mastered as 3840×2160 side-by-side 3D did better, but means I have to double the file size (data rate) to get the same image quality.

We can argue about whether or not paired 2K streams are really 4K video. In one sense, they are half vertical resolution 4K. But when 4K is used to stream 3D, we end up with half size images on the left and right anyway. The effect is therefore the same in terms of what gets delivered.

Additionally, Digital IMAX theaters, as of now, are thought of as 4K theaters but they use dual 2K projectors (they will be upgrading the theaters eventually). Digital IMAX provides a more immersive and louder sound experience, but the Digital IMAX screens are just a little bigger than regular movie screens – and not like the 70 to 90 foot tall original IMAX screens.

In other words, dual paired 2K streams used for 4K 3D end up being roughly equivalent to having been shot in 4K on both cameras due to how the 3D left/right pair has to split the 4K image anyway.

How to create 4K 3D Videos for Youtube

Using Sony Vegas Pro (and presumably newer version of Sony Movie Studio)

  • I used the MainConcept AVC/AAC (*.mp4, *.avc) codec
  • I selected Custom Frame size and set width to 3840 and height to 1080.
  • I set maximum bps to 40,000,000
  • I set average bps to 32,000,000
  • On the Project tab, I set Stereoscopic 3D mode to “Side by side (full)”
  • Upload the file to Youtube
  • Add the following as individual “tags” in the Youtube “tags” section:
    yt3d:enable=true
    yt3d:enable=LR
    yt3d:aspect=15.99:9
    yt:crop=16:9

After Youtube recodes the video, the viewer will include 1440 HD and 2160 4K viewing options. Select your 3D viewing options and select 2160 4K – note, you need a fast Internet connection. This produces a much higher quality 3D image than the normal Youtube 3D configuration.

Using Magix Movie Edit Pro (version 13 – should work on 14 too)

  • Compress the output to an mp4 video as 3840×2160 (not 1080). This creates a vertically stretched “half frame” on the left and right – however, since its 1920 wide, we end up retaining all of the original 1920×1080 on each stream.
  • Set to side by side,¬†half frame (didn’t work for me when I set to full frame side by side)
  • Select a high bit rate such as 40 Mbps or faster
  • Upload to Youtube with the tag yt3d:aspect=15.99:9
  • In Advanced settings, select “This video is already 3D, and then select “Side by side: Left video on left side”.

After encoding, this shows up as a 4k 2160 3D video and plays as you would expect, but at a much higher image quality.
