As anyone in the 3D industry can attest to, this past year thereâ€™s been a lot of PR and hype surrounding the new
Panasonic AG-3DA1 camcorder
(the â€œA1â€?). But why wouldnâ€™t there be (a lot of press) â€“ itâ€™s a â€œself-containedâ€?, High-Def, stereoscopic 3D camera system. That in itself is amazing technology by any standard, right?! I think so, but then again Iâ€™m biased. Over two years ago I started the 3D Film Factory. A small company that designs and sells â€œbulkyâ€?, but affordable 3D camera rigs (beams-splitter & side-by-side configurations). We also shoot 3D productions around the world for select clients and we offer a popular 3D training workshop. I digress. Sorry, but I wanted to confess my bias up front. Anyhow, at some point last month I decided I wanted to see for myself if this new 3D camcorder was the real deal, you know, walked the talk, so to speak. So I decided to poll a few professionals, folks who I knew had recent experience with the A1. And when I say professionals, Iâ€™m talking about 3D experts - stereographers & 3D cinematographers, whoâ€™ve been shooting stereoscopic 3D for several years or more, not weekend warriors, or self-proclaimed stereographers. The biggest surprise came right away. Believe it or not, all of them asked to remain nameless in order not to upset their relationships with Panasonic. I was surprised, but equally impressed the company unexpected clout. The second revelation - someone pointed out that although Panasonic touted the A1 as the Worldâ€™s first, professional quality, HD 3D camcorder â€“ the 3D-One HD - 3D camcorder had proceeded the A1. But the A1 â€“ still classified itself as amazing. Even I can tell you that over the past few months - many, many, many A1â€™s have been handed out to test, experiment with and just shoot 3D. As a matter of fact, Iâ€™m not sure that Iâ€™ve ever seen a product compâ€™d to this degree. I do know of several folks who have actually purchased the camera, but no one that I would consider a â€œrealâ€? stereographer. The following diatribe was assembled from my conversations from my 3D pros and from â€œofficialâ€? articles online. All in all, I think itâ€™s came out okay. So letâ€™s dig in, shall we? When comparing the Panasonic to the bulkier, heavier, traditional beam-splitter style 3D rigs (like we sell), the A1 proves to be a relatively easy-to-use, light-weight option. Yes, our beam-splitter rigs are bigger and definitely require some 3D training and/or knowledge to use properly. Fact, I tell people candidly having a rig is only 50% of shooting 3D, the other 50% is knowing how to set it up properly and shoot 3D with it. Now back to the A1 and some dry, but necessary techie facts. Weighing in at a mere 2.8Kg (6.1 lbs.), the A1 is equipped with dual lenses and two 1/4.1-inch full 1920 x 1080, 2.07-megapixel 3MOS imaging sensors. These record 1080/60i, 1080/50i, 30p, 25p and 24p (native) HD recordings in addition to 720/60p and 720/50p in the AVCHD format. In addition, it records up to 180 minutes on dual 32GB SD cards in Panasonicâ€™s professional AVCHD â€œPHâ€? mode. The cameraâ€™s professional interface includes dual HD-SDI out, HDMI (version 1.4), two XLR connectors, built-in stereo microphone and twin-lens camera remotes. Itâ€™s also equipped with a remote terminal for Focus, Iris, Zoom, REC start/stop and Convergence Point (for 3D). A nice looking 3.2-inch LCD screen provides the option to switch from Left or Right viewpoint or select an overlay image display. All nice stuff. If I had less experience shooting and editing in stereo, Iâ€™d be saying, â€œGreat. Where can I buy one?â€? After all, ignorance is bliss, especially when it comes to stereography where itâ€™s rampant. Most of the 3D people ask us to preview is unusable. Hereâ€™s the cold hard truth. When you shoot 2D, you know right away if itâ€™s good 2D photography or bad 2D photography. But creating good, high-quality 3D, isnâ€™t immediately apparent and much more difficult to attain. Because acquiring professional, comfortable 3D images â€“ requires knowledge, skill and the use of a capable, professional 3D camera system. These capabilities include allowing the stereographer (or cinematographer) to achieve 3D picture alignment - AND allowing for the adjusting of the â€œ3D effect â€œ. The 3D effect includes depth, pop and parallax. First, to achieve 3D picture alignment both lenses need to move about the X-Y-Z axis (up, down, tilt, roll, etc.), basically allowing the 2 images from each camera to â€œline-upâ€?. Conversely, to control the â€œ3D effectâ€?, the cameras must be able to diverge, or separate to bring out the stereo effect as needed. This is done be adjusting both the inter-ocular (camera-to-camera distance) and convergence (tow-in, or out). Unfortunately, the Panasonic A1 only allows for convergence control and NOT inter-ocular (IO) movement. This means that as the focal length from camera to subject varies from shot-to-shot, the only tool the stereographer has with the A1 - is convergence â€“ or the tow in/out of the lenses. In 3D terms â€“ this means the Panasonic A1 is unable to shoot anything closer than approximately 8 ft. (some claim nothing closer than about 12 ft.) and nothing further than about 20 ft. (some claim as much as 50 ft). I think itâ€™s fair to say that the camera has a â€œsweet spotâ€? from about 10 ft. to 30 ft. Adding insult, the mere use of convergence can often result in backgrounds becoming too divergent or different. As the camerasâ€™ focal trajectory increases with distance, the greater the disparity in the background images. Later trying to overlay such images in post means eye-strain. The symptom worsens for close-ups (which are not feasible at all under 8 ft.) and master shots, which begin to flatten out uncontrollably. So you have to ask yourself - when was the last time you made movie/feature/commercial/etc. without a close-up, or a wider establishing shot? In other words, despite Panasonicâ€™s claims about the A1 making incredible 3D Hollywood style movies â€“ it isnâ€™t usable for professional 3D projects, let alone Hollywood 3D movies. Unless you have a beam-splitter and side-by-side rigs standing by. What it is good at is - setting up fast, shooting quick, getting okay quality 3D in a â€œrun-n-gunâ€? type setting. Making it a great 3D ENG (news style) camera, or YouTube 3D video camera. High-quality 3D movies â€“ no. As a real-life example, when we shot Yosemite in 3D, many of the focal length up to a 1 mile from camera. Thatâ€™s a long way. So we configured the cameras on our side-by-side 3D rigs - from 3ft. to 10ft apart. The IO on the A1 is less than 3 inches. When we humans look at mountains in the distance (our eyes are 3, or less, inches apart) â€“ the dimensionality flattens out. To reverse this effect in camera and accentuate the 3D effect â€“ we have to pull the cameras apart, not tow-in or out the cameras (convergence). But regardless, most of the stereographers I spoke with generally liked the A1. They felt it was a great tool to use for non-professional, casual 3D situations. Many of them felt this way not only because of its 3D limitations, but because the lenses were, as one said â€œmid-gradeâ€?. In other words, you canâ€™t use cinema quality or prime lenses. I heard the camera described as â€œone tool in their 3D arsenal of toolsâ€?. Most agreed it was nice having a light-weight and easy to use camcorder, but conceded privately that any fixed lens 3D system â€“ is just that - â€œfixedâ€? â€“ in a flexible 3D environment. At $21,000 Panasonic claims their A1 3D camera is being â€œoffered at a much lower price than traditional 3D rigs". Iâ€™m assuming that theyâ€™re talking about the larger, bulky, beam-splitter rigs that use two cameras. Our company has several side-by-side 3D rigs priced under $1,000, while the bigger beam-splitters are $3,000 to $5,000. So hereâ€™s where I make a shameless plug. The 3D Film Factory features a host of affordable, professional 3D beam-splitter rigs. So I know for a fact that you can get 2 HD camcorders and the rig for less than the $21,000 Panasonic A1. Actually most folks I know rent their cameras for 3D projects. So in the end - if youâ€™re going to shoot a professional quality 3D project, be it a commercial, documentary, feature, or anything worthwhile in 3D for that matter, youâ€™re going to need close-ups and wide, establishing shots, right? Right. Therefore youâ€™re going to need a beam-splitter and side-by-side rig in addition to your Panasonic A1. I say, save your money and buy a beam-splitter and side-by-side and save the $21K. But then again, Iâ€™m biased.
