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.

Nokia improves image stabilization in new smart phone cameras

This is what I expected after last week’s short teaser video showing a young woman riding along on a bike – the usual CMOS “jello” was not present. Nokia has addressed the problem of jittery camera phone videos by providing image stabilization in a smart phone camera:

The Lumia 920s PureView feature is a “floating lens technology” where the camera lens actually moves and responds to jittery hand motions, ensuring a more stable image. The technology also helps out at night, brightening up images in low-light conditions, with some shots looking like they were taken by a more sophisticated DSLR.

via Nokias turnaround hopes come to focus with new Lumia phones | Mobile – CNET News.

Their original “teaser” video clip turned out to been shot on a professional CCD video camera system, hence, no jello. However, Nokia has posted a new clip showing a side by side comparison of a normal cell phone video with the new optically stabilized Lumia 920 video camera. OIS does work (I have it on an older video camera).

3D Photography Tips (3D Porch) – this is great info!

3D Photography Tips (3D Porch).

Something I noticed is that “wiggle” shots are also done differently than regular stereoscopic shots. For example, the 3rd page of 3Dporch’s tips illustrates this where the foreground is made to move while the background is held constant.

Normally, when shooting 3D we like to have the closer subjects centered at the viewing plane (in the Z-axis) which is very different than how 3D works in a “wiggle” shot.

And note how in this wiggle 3D image, framing the photo works well, while many 3D enthusiasts would call this a “frame violation”.
