we have a massive new building development going into our college, and i
would like to film it in timelapse.

I am thus looking for a MiniDV camera that will allow me to achieve this
with simplicity and at relatively low cost (sub £1000)

Any ideas?

The cheapest and easy solution is to use a webcam, and save the images (jpg
format), for example once per hour, and use a program to make an movie from
the pictures. By using a webcam it is easy to adjust the time-lapse speed
when making the final film. It is also easy to adjust single frames
(light/contrast/colour) to reduce flicker in the final film. If you use
Adobe premiere it is possible to adjust number of frames each jpg is used.
By adding Xfade between each jpg, the flicker is reduced and the film is
much better.
I have a webcam taking one frame per 24H (at noon). I use 5 frames per jpg
with Xfade between each. This makes one year into 1 min 15 sec film.

I wonder why most of this software only allows the image to be saved as a
..bmp without a choice of saving as a .jpg.

I have to admit that I'm not too up on these things technically, but the
resulting image I get from an image compressed down to even 50k on my
ancient 1.3mp Olympus digital camera is infinitely better than what I'm
capturing as a 300k .bmp using a cheap webcam or security camera... all very
disappointing.

It's all down to the software and quality of sensor in the webcam.
Most webcam security software will allow the native .bmp to be
compressed to the lossy jpeg format for transmission by email,
ftp'ing to a 'live' window on a website etc.

The Sony CCDs are the best for low-light, but most webcams only
have CMOS sensors. Unfortunately the OP's QC5000 can come with
either CMOS or CCD sensors, but probably CMOS in the UK.
The resolution of the sensor is the other thing - most are 640x480
pixels, so images will never look as good as from a digital camera.

The current webcam of choice for low-light is the Philips SPC-900,
which uses the excellent Sony ICX098BQ CCD sensor.

I'm using a Philips SPC 300 camera, however its performance pales into
insignificance in comparison to my old Philips PCA645, which unfortunately I
can find absolutely no drivers for Windows 2000.

It delivers crystal clear pictures with drivers downloaded from Microsoft,
but unfortunately in daylight the resulting image is bright blue, due to the
fact that none of the set up menus for brightness, contrast, background or
gama are included along with the drivers.
