Editing a 3D Movie

Ron Proctor kindly explained how he assembled his 3D video (see previous post:"Low cost 3D video") using Adobe Premiere:

We started with two full color video channels (right and left) – anaglyph (the red/blue method) is not ideal, but it is accessible because you don't need a special screen (just special glasses). I'd like to try this with polarization or autostereo some time.

For the anaglyph version, we overlaid the two tracks in a video editor and set the compositing mode to "screen" (also known as "add" in some editors). We removed the red channel from the right, then we removed the blue and green channels from the left.

We also had to adjust the offset a little bit so the "focus" was on one of the middle birds. Whatever the two channels "line up" on will be the "focus," also known as the "screen plane depth." Whatever is in front of that will "pop out" and whatever is behind will "pop in."

The video editor we used was Adobe Premiere CS4, but you can also do this in cheaper / free software. I also tried it in the video sequence editor in Blender and got a favorable result.

The following video shows a slightly different method of removing the color using Final Cut Pro: Make a 3D Movie: 4-Minute Film School.

Sony GV-D200 review

Image
Sony GV-D200 I've been using a Sony GV-D200 deck to transfer old Video8 and Hi8 tapes. Some of these tapes are over twenty years old, and no longer having a Hi8 camcorder that worked I was concerned that if I didn't do something about transferring them to a more modern format soon, I might never be able to. While Sony no longer make camcorders that use these tapes - that I know of - Sony does still sell the GV-D200 deck (or Video Walkman, as it's sometimes labelled.) They also offer the GV-D800, which is almost identical but adds a small LCD screen for about $120 more. I didn't think I'd need a screen since I was using this to capture to the computer, but you will need an external monitor when you first set it up. Physically, the device is small. At 5 7/8" wide, 5 3/8" deep and 2" high, it's the smallest video deck I've encountered. I used to have a Video8 deck that I thought was small; and it was twice as deep and twice as high. The t

Response: Which iPhone to Get?

Image
In response to my iPhone musings, I got the following reader email which actually sums up a lot of my second and third thoughts too: You might have a point about the fancier camera, but otherwise I would buy the smaller model. Its screen is about the same size as that of my Nexus 4, and I don't feel at all like it limits me with a too-small screen. But I do sometimes stretch to get my thumb the reach to the other corner of the screen. It is plenty big for a phone. A phone is a pocket thing. (Well, in my case it lives an ancient REI soft sunglasses case that I have on my belt.) Ubiquitous, handy, convenient, almost always with me. Small is crucial for all of that. Certainly a large screen is cool, but you need a place to put it: don't break a fundamental feature of a pocket phone by getting too big. That is what your small tablet is for. I have my phone with me almost always. I have my Nexus 7 tablet with me nearly as much. The bigger screen is great, yet it fits in some

Should you buy the Sony NEX-FS100 Kit Lens?

Image
The Sony NEX-FS100 is available in two configurations: B & H : NEX-FS100U Camcorder only $4,999 B & H : NEX-FS100U (with 18-200mm lens) $5,599 But what does that extra $600 get you? It get's you this: Sony 18-200mm f/3.5-6.3 Zoom Lens for NEX Camera This lens is also available separately for $799.99, so at $200 off you'd think everyone would be jumping on it. But not so fast... In his article about switching from the Canon 5D Mark II to the Sony NEX-FS100 , Paul Antico  at Need Creative says of the kit lens: 7) Its 18-200 F3.6-6.3 kit lens absolutely sucks and should be avoided (thankfully, you can order it without one) [ 1 ] But is it that bad? At B & H 's site, 43 reviews give it an average of 4.6 out of 5 stars. That's not a bad rating, though many of these people are using it for stills, and the most common complaint noted is how large and heavy it is. Of course this feeling of size would be exacerbated when you put it on a tiny camera
