Wonder what gives? It's been known to happen before that Youtube pulls controversial ufo (Fortean-style) videos. Charles Fort .. early chronicler of things mysterious. Compiled vast reams of data and accounts .. threw them all into the fireplace out of frustration when no-one demonstrated particular interest. Later he re-assembled (largely from memory) the various tales of high-strangeness. So anyhow, perhaps it's just a temporary glitch .. that video could stand a bit of editing anyhow ... cut the dead piece out of the middle and replace the whole bleedin dialogue with upbeat music. The whole thing's a bit raw and aside from the predictable oooh's and aaah's .. not too much to be gleaned from the dialogue anyhow .. and the sound of the truck starting up has got to go. The whole phenomenon should be autonomously monitored anyhow .. how's this for a suggestion. Get your local highschool electronics wizard onto it. This is one of a couple of suggestions. As a means of reliably detecting the presence of the light (and activating an alarm activated video recorder (think surplus time-lapse video recorder) they have alarm activation and in real time recording (for pre-set duration). Time lapse vcr's are a dime a dozen nowadays as digital video recording has taken over the security industry .. there are even 12 volt models available although one could easily run it off an inverter as well. Anyhow as far as the sensor's concerned ... it would require two tubes both having light sensors located at the bottom of the closed end. One is pointing directly where the lights appear and the other is pointing slightly off to the side (where they don't appear). The two are hooked together through a differential comparator circuit ... as soon as light appears in one tube (and not the other) the alarm bells go off. This two-tube differential comparator design allows us to take into consideration normally-occurring changes in ambient lighting .. commonly referred to as sunlight and darkness. As for the video camera itself ... we could use a two-camera piggy-back design. A versatile wide-angle camera mounted on-top of a mega zoom lens .. with it's focus fixed at infinity. Mount the cameras so they are coaxial .. whatever appears in the middle of the wide-angle view is EXACTLY where the zoom is zoomed on. It's hard to find images with super zoom lenses ... have to zoom in and out and lose focus etc.. Just leave the monster zoom lens at infinite focus with auto iris adjusted appropriately < that might be the tricky part ... these auto iris adjustments come in various flavors. Including solid state electronic board-level artificial iris .. in addition to dc and video driven iris control. This to compensate for the wide dynamic range the camera is expected to handle .. from extreme low-light levels to quite bright. Use picture in picture (PiP) features for two (or more) simultaneous camera recordings (with time-stamp) Try filming through an adjustable polarizer .. determine whether the light is linearly (or circularly) polarized. Have a super-ear style microphone close to the highway to transmit via FM family radio band the sound track to your video (taken from six or seven miles away). Go to your favorite online auction site and look up 'tv zoom' or 'computar' or 'cosmicar' for mega zoom lenses (cheap) .. just get the 'c' or 'cs' mount style ... avoid custom lenses. Here's a nifty hack .. buy surplus portable dvd players .. just cuz the dvd won't read doesn't mean the screen doesn't work. Look under 'portable dvd +bundle' you can normally get 4 or 5 at a time. Generally their batteries are shot (but that's ok) just hook up alternate power in. All these units allow for a/v in if you have the right patch cable .. it's 3 RCA to 3.5 mini plug. Now you can watch your ccd image on this convenient view screen. Just select a/v in on the side of the player. Video signal may connect to the white RCA which is normally left audio .. the pinout may not correspond to yellow rca for video in .. big deal. OK that's enough for now .. sorry if I bored you .. but this is all definitely in the right direction. Back to you : )
