"3D is no longer exclusive to movie studios. If you can scrape together two camcorders, some sticky tape and access to a hooked-up computer, you're just a few steps away from making your own three-dimensional cinematic works of art.\nThis is largely thanks to YouTube's free online 3D Editor suite. Mashable spoke to Samuel Kvaalen, YouTube software engineer who helped develop the product. Kvaalen told us why the video-sharing company created the tool in the first place: \"The idea was trying to make creating 3D videos accessible to as many users as possible in a simple, easy manner.\" \nSo is it really easy to make your own 3D YouTube video? After a quick walk-through of the software with Kvaalen, we tested it out. Here's our super-simple, step-by-step look at how to shoot and edit a three-dimensional video. \n1. Shooting\n\n\n\n\nAs far as hardware goes, you'll need two cameras, ideally the same model, although you can use any two that can record at the same resolution. You'll also need some way of holding them together and some 3D glasses so you can edit and view the final result.\n\n\n\n\nWe used two Cisco Flip MinoHD pocket video cameras. We separated them slightly with Blu-Tack in order to reach the power button on the side of the camera. Be sure to use a ruler or other straight surface to ensure the camera's lenses are at exactly the same height.\n\n\n\n\nOnce you've got your cameras lined up, you need to attach them together. We simply wound masking tape around the bottom of the cameras to hold them in place. Think of it as recording separate footage for your left and right eyes. This is the basic principle behind how 3D technology actually works. \n\n\n\n\nWith that set-up complete, you're ready to go. What to shoot is, of course, up to you, although Kvaalen has some pointers to share. \"You don't want to film objects that are too close \u2014 you want to try and keep it at a decent distance \u2014 a few feet away is ideal,\" says Kvaalen. In addition he suggests keeping the camera as stable as possible. This will yield the best results. Finally, try and press record at exactly the same time on each camera.\n2. Editing\n\n\n\n\nOnce you've shot your footage, signed into your YouTube account and uploaded your two videos, head over to YouTube's 3D Editor. It looks similar to the ordinary YouTube Editor, but you'll see tabs on the bottom right that relate specifically to 3D editing. You can now drag and drop the two clips that you want to use to the \"left\" and \"right\" boxes. \n\n\n\n\nThe first thing to do is get the time sync right. Whereas this used to be done manually with editing software, the 3D Editor does it for you. Kvaalen explains: \"You want to start filming with both cameras at the same time but that's pretty much impossible, you'll always have at least a few milliseconds off, so this uses the audio to sync them automatically.\"\nBy \"listening\" to the audio from the videos \u2014 even just ambient sound \u2014 the Editor will be able to accurately time sync the two videos.  \n\n\n\n\nNext up is vertical alignment. Kvaalen offers some more advice: \"Users should bolt the cameras together so they don't move relative to each other, or \"vertically shift,\" but there is usually a small vertical difference in height. This tool lets a user manually suggest a vertical shift percentage.\" As far as our attempt at guestimating the shift, we just kept tweaking until it looked right. Start at plus or minus 10% and keep going until you get the best result. \n\n\n\n\nFinally, once you are happy with your video in the preview window, you can add a title in the top right hand box and publish it. After the video processes (usually a couple of minutes) you'll have a shareable 3D video to impress your friends!\n3. The Results\n\n\n\n\nTo view one of our test videos in 3D, you'll have to grab your 3D glasses, but even if you can't find a pair, we can report we were happy with the results. \nWith relatively little hardware and a pain-free editing process, YouTube's aim of making 3D video creation simple, easy and \"accessible to as many users as possible\" has been achieved with the 3D Editor. We think there will be a lot of YouTube users having lots of fun with this 3D tool. \nHave you used YouTube's 3D Editor? How did you find it?
