Not long ago a neighbor friend parted with a Kodak ZX1 camera. The box hadn't been opened so it was new.
The camera is nice and all but I notice that when panning, the image blurs. I tried the HD60 frames mode and the blur is still there. What causes this? The Flip doesn't have this problem.
I also wanted to ask Kodak a question but their support email cannot process my question? It has to do with VGA recording mode automatically shutting off after a few or up to 15 seconds. |

It takes a small amount of time for the image sensor to capture a frame's worth of light
Although the time is short, it can be long enough that continuous motion moves across a few sensor pixels in that time, causing a blur
Better sensors have smaller capture times, and less blur
Also, better cameras can have improved software that reduces this blurring even more
Basically, it's because it's an ok camera, but not a good one
There's a reason kodak is filing for chapter 11 ;-)

dloneranger is right on. Another way to think about it is to pretend you are taking a picture. When something is moving, you need a fast shutter speed in order to reduce blur. There are other factors which can cause blurring during panning such as rolling shutters or how the image is stored in the camera frame by fame or field by field. Another factor which is evident is compression of object to the direction of motion and dilation of objects away from the motion. Tilting or shaking the camera will cause distortion as well based on field of view of the camera with wide angle cameras suffering less for example.
Bottom line, some cameras do a better job this than others. Even high end cameras suffer from this. Notice next time you watch a movie pay attention when the camera is panning, it is most often done slowly for a reason.

Their support rather stinks. I saw examples of service help from there and one user was like: "Forget it, you failed miserably, thanks for nothing!" and the support staffer said: "Thank you and you're welcome", lol.
Even if you pan slowly with this Kodak camera there is a stutter effect like as if the frame rate is rated at 10 frames per second.
The Flip, in my opinion, was the best pocket sized camera for consumer HD. Night shots with ambient light weren't as grainy, sometimes you couldn't really see any unless you paid really close attention to it, movement was fluid and crisp and the colors didn't overburst, very well controlled. Manual controls are something I woudl had like to had seen. They came out with the 3rd gen that had stabilizer but shortly after, poof.
Way to go Cisco. Buy out a company, Pure Digital, for a little over a half billion dollars then months later down the line: "Eh we're washing our hands out of the deal" Ever think to maybe sell the product line to another company maybe? Duh. I knew it was a bad move. Cisco is not a multimedia business, they are a networking business. What were they thinking? I'm not buying the "because smartphones have cameras" bit. Pocket cameras have their own marketplace and if that was the case Kodak would had stopped making their lines of cameras and started going into the cell phone business full throttle.
I remember the old VHS tape recorders with the 10,000th shutter speeds on them. Those were annoying to watch sometimes, lol. But the video was sharp!
I'll always be an analog man, deep down. Give me a tape camera with a CCD lens any day. The only real cameras I was satisfied with were my old VHS, compact VHS and my Digital 8 which was the best out of all of them until I had that lens problem. I have old childhood tapes on compact and regular VHS from well over 20 years ago. Some of them were done in EP mode and the quality of them looks better than a lot of the consumer junk that's out now as far as standard definition quality goes! In my opinion at least. Well, minus the chroma issues in EP but at least the details were there, lol. The tapes back then look the same as on the day they were recorded. I kept them well.
I've also noticed in some TV shows, Harry's Law being one of them, if you pay attention to the panning you can notice CMOS distortion where vertical lines will sway. Looks like a part of Hollywood is using this for effect now. |

I did get to email Kodak the question about the VGA quitting out and I just got a response back
I'm being asked about my card. Like what kind am I using. I don't see how this should matter since all other modes on the camera work fine, all HD modes including 60 frames works fine with my card so it can't be a speed/keep up issue. VGA is less bits and the card functions in the camera as it should. |
