floating black pixel

I have a new DVD camcorder (Sony DVD653E) and every film I shoot contains a
small black dot that seems to float in the bottom right corner of the frame.

Any idea what is causing this and how to fix?

Dirty lense? Dead pixel/s? Residue
inside the lense? Who knows?

I'm thinking I would return the camera
for a replacement.

Dead pixel. In your case, apparently a dead pixel in the
image pickup chip. They happen in LCD screens (and
plasma displays, etc. etc.) It is up to the manufacturer
how many dead pixels (and what kind: black, white, color)
will make the device returnable. Just one black pixel in the
corner may be within the range of "acceptable" in their
opinion(?)

My local computer dealer has a sign posted with the
policies of all the different makers of LCD screens and
they range from 2 pixels to 8 dead pixels before a screen
is returnable.

I got over 1200 hits on Google for: dead-pixel sony-camcorder
but most of them were for dead pixels in the LCD viewfinder
(which Sony won't fix under warranty unless it is really bad.)

I'd try to return the unit for a replacement ASAP!!

John, Richard,

Thanks guys.

The camera has gone back to SONY. I also asked them to exchange for a
different camera. One the records in DV-AVI format. I learned on
myvideoproblems.co.uk that the compression ration on MPEG-2 is 20:1, whereas
the compression ration on AVI is 5:1. In addition, only one in four MPEG-2
frames are "real life" to reduce space. The others (called i, b etc). The
quiality difference shows... unacceptable bluriness (which highlights the
dead pixel) when viewed at full screen on my PC. I cannot imagine that it
will be any better on my big-screen TV.

On top of all that, Movie Maker will not edit MPEG files. Surely Microsoft
should respond to SONY's market share and include the right script/codecs or
whatever to allow MPEG-2 files to be edited on MM.

THanks again for your help

Let us know what Sony does about the
issue.

Editing temporally-compressed video (like MPEG) is a
controversial topic. Some people seem to think it is fine,
and others of us can hardly watch it. As you have discovered,
because only a fraction of the frames are *real* (the rest
are derived on-the-fly), it makes it much more difficult
to edit. The intermediate frames must be re-created, the
edit/effict applied, and then re-compressed to MPEG.
This decompression/recompression step is almost never
free of its own artifacts, and that is why MPEG editing
is not widely supported, it is too problematic for the
majority of the users.
