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:

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.

3D isn’t awful – its the bad 3D that’s awful!

I went searching through Youtube this evening for 3D content and found plenty of it – and plenty of it was basically awful!

Badly misaligned left and right eye views, edge violations, poor quality 2D-to-3D conversions. Not the sort of quality that will encourage others to enjoy 3D.

It is good to see people trying to do 3D – but it will take time for new enthusiasts to learn how to shoot and process 3D correctly. As 3D hobbyists ourselves, we need to help teach others how to create good quality 3D.

3D video of Yellowstone’s Old Faithful Geyser eruption

3D video of Yellowstone’s Old Faithful Geyser eruption – YouTube.

This is a “fake” 3D video created from a 2D video shot from the overlook several hundred feet above the geyser basin.

This video was created by time shifting a 2D video to produce separate left and right images – creating a very nice effect of the steam cloud coming out of the screen at the viewer.

To  create this effect, the one 2D video was dragged to both the “left” track and the “right” track in Magix Movie Edit MX Plus. Then, using the Stereo 3D effects tools, click on the “Shift Frames” – or + options. For this video, the right track was shifted 5 frames to the left. This has the effect of moving the steam cloud forward or towards the viewer.

Because the steam cloud is constantly moving, by shifting one copy of the video sequence off by 5 frames, the left eye sees the original and the right eyes sees the original but shifted by 5 frames when the steam has moved slightly. This, in turn, is similar to having recorded a separate left and right video image. But instead, I cheated used only 1 camera.

This was shot on a single, handheld Lumix GH-2 with a 45-200mm zoom lens. My tripod was simultaneously in use shooting a time lapse sequence using a Canon SX1 which I have not yet processed.

Civil War Battle Re-enactment video in 3D – Battle of Deep Creek

This is a ten minute teaser – perhaps a lot more to come! – of the Washington Civil War Association’s Civil War era history, camp and battles at Deep Creek Farms, Medical Lake/Spokane, WA. This video includes scenes from two battles combined into one, plus some camp scenes. I have about an hour and a half (times 2!) of 3D video to use in eventually putting more short videos together from this event.

Need to click on the link since the embedded Youtube video player does not yet handle 3D.

Courts ruling that video recording police in public is legal

It is hard to believe, in this YouTube age, that taking video of people in public could be a crime. But the police are serious about not wanting to be recorded — and they have been making arrests to prove it.

via Adam Cohen: Is Videotaping Police a First Amendment Right? | TIME Ideas | TIME.com.

A U.S. Court of Appeals in Boston, a Court of Appeals in Chicago, and a filing by the U.S. Department of Justice are establishing that the people have a right to record police activity in public. Continue reading Courts ruling that video recording police in public is legal

Converting individual .MTS AVCHD files on Mac OS X

I have deleted much of this original post since it was not that useful.

Until Final Cut Pro X, Apple did not support AVCHD file formats well. Importing an AVCHD file involved a time consuming and file expanding conversion from AVCHD to either Apple Intermediate Codec (AIC) or ProRes codec.  The files are often 3 to 5x larger than their originals. The only benefit was the editing was faster than if the files were still in AVCHD format. And you had to import from the original camera folders – the whole package – you could not import individual .mts files.

Since FCP cannot import individual MTS files (not part of the original file folder layout), I came up with some alternatives.


If you have a very fast Internet connection, just drag the .mts file directly from the camera and upload to Youtube.  When the upload is finished and processing at Youtube is finished, you can use Youtube’s new editing tools to trim your video.


  • Your files are going be encoded (in the camera) at data rates of 17 to 24 Mbps, which means they will be large. If you have a long video or a slow Internet connection, this may not be the preferred method.

Option 2 – Converting to MP4

Use SmartConverter (free version is okay for this) to extract the MP4 video stream that is hidden inside the AVCHD stream.  The conversion will take seconds or tens of seconds – its fast! – and the file will appear in Movies\SmartConverter.  No transcode has taken place – what you have in your MP4 file is the original bits hidden in the AVCHD file. You can edit the MP4 file but rendering is really slow.

Option 3 – Use FCP7 to Log and Transfer

Standard feature of FCP. Requires the original full camera folder layout. Does not work with individual .mts files.

Option 3A – Use iMovie 8 or newer

Import the files and convert them to huge AIC files. Does not work with individual MTS files.

Option 4 – NEED to convert a single MTS file

Use VoltaicHD from Shedworx.com if you need to convert individual MTS files.

Option 4 A:

Use SmartConverter to convert the .mts to a .mp4 or mov file containing h.264.

Open clip in QT7 Pro (doesn’t seem to work in QT X). Trim as needed. Export to ProRes 422 (LT).

Import clip into FCP and add titles, transitions, overlays, etc, as needed.

Export to Elgato Turbo.264 HD device for fastest conversion to an mp4 file for upload.

Option 4B – Use Turbo.264 HD

You can now use the Turbo.264 HD software to import directly from the camera (AVCHD), and you can mark some editing/trim locations. Turbo.264 HD will import, cut as desired, then re-assemble the pieces into your desired .mp4 output file. See the instruction manual for details.

If you do not have a quad core processor and you do a lot of conversions of video to 720p (in particular) or 1080p, Turbo.264 HD is a great product. It really does speed up the conversion process quite a bit. You can also batch up a whole set of files to convert, then walk away while it does all the work. Keep in mind that the maximum mp4 output bit rate is limited 10 Mbps. That’s fine for 720p but not so good for much 1080p video.

Why not use the famous MPEG Streamclip? Every time I tried to output through the Turbo 264 device, the file ended up with the wrong dimensions.

Bottom line – its possible to work with individual .MTS files. Would be nice of Apple and others had direct AVCHD support without doing file conversions or FCP X, which was late to the game. I do not have FCP X and do not plan to install on my notebook as it is not compatible with my FCP7 projects.

Amazing – Create 3D video from old 2D videos

California/Arizona Time Lapse on Vimeo by Dan ...
Image by cloudchaser32000 via Flickr

This is an amazingly nice 3D video created by Dan Eckert as a conversion from 2D video.

How the heck does that work? As long as the camera is moving slowly left or right during the video shoot, you can create a fake 3D stereoscopic view by offsetting the 2D video by a few frames. Use the original video stream for one eye and the offset stream for the other eye – your brain sees this as three dimensional. The effect is amazing.

Youtube now provides a 2D to 3D conversion feature as well.

Television rules the nation: China goes 3D | 3D Media Revolution Blog | 3D Video Player & 3D Video Converter.

I decided this week that I will start shooting 3D video.

I have had an interest in 3D going back to the 1980s, when I visited an exhibit on holography. I read a couple of books on holography but alas, holography was not something I was in a position to pursue.

I recently came across one of those lenticular-based 3D images on the cover of a product and that got me reading about 3D technology once again. After some tests using a single camera to shoot some 3D video of static objects, I found myself hooked! I now plan to get a 2nd camera so I can shoot true stereographic video.  (But do not expect to see much here for as much as 1 to 2 months as I have too many other things to deal with before I can get to creating great 3D videos worthy of posting!)

3D, other than in video games, seems to still be stuck in the pre-fad stage of a few experimenters. But this will change, and soon. First, Youtube is providing very good support for 3D – once a properly formatted 3D video is uploaded, Youtube offers to present the video in all of the popular 3D formats – have it your way! Second, Peter Jackson’s movie version of The Hobbit will start to come out in about one year. The Hobbit is being filmed in 3D and I suspect will greatly propel interest in 3D forward.

3D TV will take a long time to arrive, though, because so many people have only just acquired an HDTV and are not in a hurry to rush out and purchase a new 3D HDTV. Over time, as more and more 3D TVs are in use, then 3D content will become more popular. May as well start shooting 3D now as the originals shot today and can be converted to any desired format in the future!
