More JVC GS-TD1 3D Camcorder First Impressions and a Sample Video

February 25th, 2011 · 2 Comments · Shooting in 3D


Here is something interesting coming from iWATCH3D from an event in JVC’s London headquarters where they presented the upcoming JVC GS-TD1 3D consumer camcorder. Michael has managed to paly a bit with the 3D camcorder to get some good hands-on impression and also to record some sample 3D footage that you can see online here on YouTube 3D or download the video from the links bellow with a higher quality. I’m just going to quite the pros and cons that he has summarized in his short overview and you can read the full hands-on impressions on his website.

Here are some of the nice things on the JVC GS-TD1 3D:

– F1.2 lens has got to be the biggest plus. I didn’t yet see any super low light done by it, but from the indoor shots I’ve done, it certainly didn’t show too much disturbing noise artefacts. Makes it capable of nice Bokeh shots, not really DSLR league but enough to make your depth bracket be isolated from the background.
– Manual controls. I’ve seen the settings that I would want to set myself to manual when shooting at normal pace. Focus, aperture, shutter speed, white balance, ISO, audio input/output levels, parallax can all be set before pressing record.
– 3.5″ 3D LCD screen. Yes 3D on it looks Ok, but what I liked best was to swivel the articulating screen to an angle that I saw the 3D stops working but the two streams overlay so I can monitor parallax values and adjust my position to the subject for best 3D.
– Ability to shoot 3D time lapses is something that I just didn’t get enough time to check out but I bet it will look good.
– 3D MPO photos in 1080 resolution… not as good as Fuji’s W3, most probably, but it’s there and occasionally why not make a 3D picture?

And what can be further improved in the JVC GS-TD1 3D:

– At the wide end of the lens it’s 35mm equivalent is only 42mm which some could say make them look home-video-ish. It’s the same lens that they’ve used in the other new 2D top end consumer camcorder the HM960 but to have a compact size 3D camcorder they used two smaller 1/4.1″ CMOS sensors, compared to HM960s 1/2.3″ that makes it have a wide end of 29.5mm (35mm equivalent).
– Interlaced recording. Personally I’m not a fan of it in either 2D or 3D. Even the best deinterlacing software will not cope well with fast motion/action/panning etc. Especially in 3D you want sharp images for the brain to get more info to be able to recreate the best 3D effect.
– CMOS’ famous rolling shutter. It’s there but considerably less painful than for example my Canon 550d’s (T2i). So a good job by JVC, but in a perfect world, for 3D specifically, again I’d prefer global shutter.
– Electronic image stabilizer. An optical would have been better, mainly as it’s a consumer product and it’s designed to be handheld.

Michael compares the JVC with the Fujifilm W3 and his custom dual Canon 550D (T2i) 3D recording rig and you should also have in mind that the JVC GS-TD1 3D camcorder is a consumer product and not a professional one. And JVC’s product will probably have a serious competition with Sony’s upcoming HDR-TD10E 3D camcorder and hopefully we’ll soon start seeing more information and demo footage from Sony’s product as well. Personally I’m interested in both and will try to get them for testing if possible, because I’m planning to purchase one of these two models for shooting 3D video as any stereo 3D enthusiast interested in 3D video recording on a non-professional level probably is also interested in them…

Wild Nature Images Stereoscopic 3D Sample Video by Ron Niebrugge

January 30th, 2011 · 6 Comments · 3D Movies & Videos


Here is a short sample stereo 3D video provided by the Alaska photographer Ron Niebrugge from Wild Nature Images. Ron runs a stock and assignment photography photo agency called Niebrugge Images is Alaska that is specialized in offering landscape, wildlife and travel stock photos and now he is also providing 3D HD Videos. The sample available here shows some of his work in stereoscopic 3D format from Alaska, Las Vegas and San Francisco, both in time-lapse format as well as real time videos. The sample short video clip is in Side by Side format, 720p half horizontal resolution (squashed), so you need to select 16:9 aspect ratio when opening it. You can also take a look at the clip in anaglyph red-cyan format available on YouTube. As usual your comments about the video are welcome…

My Custom DIY Beam-splitter 3D Camera Rig Project Beta Stage 1

January 20th, 2011 · 14 Comments · Shooting in 3D


I’ve been working on a DIY beam-splitter camera rig for shooting stereoscopic 3D video for a while now with the idea to have something built mostly from different computer related parts I have handy in order to lower the total cost of the project as much as possible. With the cheapest professional beam-splitter camera rigs starting at about $3000-4000 USD and going to tens and even hundreds of thousands of dollars for the high-end solutions it is quite hard for an enthusiast to start shooting 3D video to experiment or just for fun and to learn from the experience. So it is no wonder that a lot of people start building their own custom rigs, and my idea with this is pretty much the same…

At the moment the first phase of the test rig design is close to its completion, I’m just waiting for the two rails I’m going to use for adjusting the interaxial distance of the two cameras. I’m using two consumer grade HD cameras from Sony that I have, along with a custom modified set of LANC-based remotes for controlling the two cameras simultaneously, a small 50/50 beam-splitter mirror. The total build cost of the initial rough design should be about $100 USD, and as this is just a test project, the next version will probably look and work even better. The simple reason for that is the fact that while designing and building I’m learning on the go and getting new ideas to try, but the idea is still to remain a very affordable and easy to build design.

The idea for this rig is to be portable and light, with the next version planned to be built with parts probably from aluminium. The half mirror size is about 15 centimeters (around 6 inches) in width with the planned interaxial distance available to the user to be about 11 centimeters (around 4.3 inches). This of course is for shooting 3D video of closer objects as for recording landscapes or wider scenes a parallel rig with much bigger interaxial distance is usually a much better choice. After the rig is finished I do plan to also try recording HDR video with the two cameras, but that is a kind of a side project and another option you could use a beam-splitter rig for. The initial rough tests I performed today were quite promising and I expect to soon be able to have the interaxial adjustment rails attached and to record some test footage and post it here.
