Stereoscopic High Speed Photography

[Eric Deren]

Just a quick note, I just released another stereoscopic video short:

http://www.dzignlight.com/stereo/240fps.shtml

summary: High speed 240fps stereoscopic 3D digital video of two Toyota FJ Cruisers fording a puddle, and two weapons instructors firing M4 rifles from the Gryphon Group military training facility.

Enjoy!

You can use a lot of different cameras, my favorite being the Phantom series by Vision Research, but if you want to get it shot for under $2000 you'll need to use consumer Sony cameras. Although the footage records to tape at the regular HDV 1080i raster, it appears to be more like standard def.
This is still pretty amazing for stereoscopic 240fps, under $2000.

"it appears to be more like standard def."

or even worst. i have see it, and imho its only good for web.
but yes, 240fps is 240fps.
i hope with memory card camcorders, soon we can get HD (or real SD) resolution with high speed.

It's actually starts out as 240 *fields* per second, 120 frames per second.
Since most playback options for stereoscopic involve progressive, you have to do something with those fields, so I use them to allow me to slow the footage down by a factor of two. Of course, there's a quality hit there, too, but the reality is you'd be throwing those fields out regardless, why not use them to increase temporal resolution?

Lest anyone feels like I'm trying to compare this footage to a real rig that costs over $6000 a day to rent... remember, it's just a US$2K rig TOTAL COST. Don't expect too much. Watching stereoscopic 240fps in low resolution is better than watching a black screen, IMHO. :-)

In answer to your question, I think a lot of consumer Sony HDV cameras have this feature now, but the Sony website would be the best place for that information.
