Default Pixel Burn

I have an issue with my Canon ZR MiniDV camcorder. I have one pixel
fairly central in the middle of the screen that is burnt out.
Unfortunately it is showing in all my footage. Is there any software
that can get rid of this noise afterwards when I am transferring to my
computer and editing?

I also just wondered if anyone has a webspace explaining all the
different consumer camcorder choices both analogue and digital but
especially digital and across all different formats offered? I think
it could be useful for people looking to buy a camcorder today with
all the different choices available e.g. MiniDV, DVD, SD Card, Hard
Drive etc. Also explaining the advantages of 720 and 1080 compared
with each other and the different types of lens and features that
camcorder have etc.

Cheers,

John

Which editing software do you use? You'd be better off using a semi-pro or
better editor, with which you can create your own mask or filter to hide the
dead pixel.

If you get rid of it during capture, you'll be introducing another
compression cycle into the workflow, which is not good - the improvement
from getting rid of the pixel will be offset by the overall drop in quality.

Viewers typically see past such distractions, anyway. That's why so many TV
companies get away with their logo "bug" on screen.

If it is also on the actual recorded footage when played back on
another medium such as PC monitor or burned to DVD etc,
then it ain't a dead/burned pixel.
A dead pixel is on the display, such as the visual screen with
camcorder, or an LCD, or whatever. If on the actual footage
then the prime culprit will be a damaged lens, which is relatively
easy to replace. (Though not nessacarily cost effective).
Very first step - clean the lens.

There is plenty of "webspace" explaining the pro's and con's.
And there is a well established online lump of cleverness that can
produce the info, it's called google.
An excellent site: http://www.videohelp.com/
Sites worth browsing and clicking the links:
http://reviews.cnet.co.uk/camcorders...9293142,00.htm
http://www.videojug.com/interview/hi...ion-camcorders
http://www.videoforums.co.uk/camcord...own-route.html
http://theinsider.pricerunner.co.uk/...-def-camcorder
Just a few examples to use as google search criteria:
Hi-Def 1080p
Progressive Vs Interleaved
Hi-definition camcorders



Cheers,

John

Err, if the pixel is dead then it isn't sending any information
back to the image processing circuitry (hence either a white or
black dot), if the lens was to fault the problem would be
intermittent as focus and iris settings would mask the optical
damage, one would certainly get some sort of colour/movement
information being processed - I actually own a telephoto lens
from my old 35mm SLR days that had a ruddy great chip on the
outer lens but the damage is not noticeable on most negatives!

Sensors can have dead pixels- my XM1 bought in 2001 had one prominent enough
for Jessops to replace it.
