best camcorder ever image
Q. Let's say I had the best camcorder ever, and mankind had a spaceship that could travel the speed of light. And they allowed me to put the camera at the tip of the spaceship and a constant stream to their monitors at NASA. Seeing on how when we travel the speed of light we are going through time at the fastest rate possible, what would it look like on the monitor?
And when it stopped traveling, would you be able to see the future from the present?

Answer
You can only go arbitrarily close to the speed of light (with respect to some reference), not at it.
Near the speed of light (from the point of view of an observer), light would still move away from you and toward you at the speed of light as seen from your point of view. Your field of vision would become constricted to the direction of travel and experience colour shift and lengths would dilate differently in different directions - see other answers.
At the speed of light (impossible) your whole journey would take zero time from your point of view, even if it lasted forever. If you travelled a finite distance at the speed of light (impossible) it would appear to you that you instantly teleported a distance in space and jumped into the future.
The reason that light can (and must) travel at the speed of light is that it has no mass.

Is the Canon XA10 HD Professional Camcorder good for film making?
Q. I'm starting out so this would be my first camcorder I have ever used.
Answer
Hi "Bittercold":
Since you already asked twice last month about miniDV camcorders, I won't repeat any of the other Y!A pros' advice on that subject. I will, however, point you back to fellow Contributor "L's" Answer to you regarding the AVCHD format issues that the Canon XA10 records all its files in: http://answers.yahoo.com/question/index;_ylt=AmxPdh4o1WYVv83bjYM0h6Xsy6IX;_ylv=3?qid=20120324030021AAL8XNH
If you are interested in "filmmaking", then you are going to have to plan for editing, and AVCHD's lossy compression codec isn't the best for frame-accurate edits.
If you've never done any camcorder shooting at all, you might be better served starting out with something used from a good camera store or pawn shop, and making sure some of your budget money goes into the extra RAM & fast hard drives (among other things) that editing HD footage will require. Try a $250-$500 test run, before you go spending almost 2-grand.
Feel free to update us with what kind of stuff you plan to shoot, for better feedback. It makes a difference:
When I get hired by Coach Schuman or one of the other Yahoo!Sports' "Rivals 100" coaches to videotape a football event, they expect me to bring a miniDV format camcorder, not a flash-card AVCHD or H.264 unit, no matter how expensive. And small-is-good with run & gun sports shooting, so I use a Canon ZR-series or Panasonic GS-80 (both under $700), rather than my $3000 Sony Z1U. We shoot everything in 4:3 Standard Def, since that's what the editor, the other coaches, and all the other shooters work in. And the low-compression DV codecs make for good action footage and easy edits.
The Canon XA10 has pro-audio features, good Canon glass optics, dual SD slots, etc., but I can't say if it's the best deal for you.
hope this helps,
