| Jos,
The biggest thing to be prepared for is the higher amount of BW DVs
use. You're going to have to have more BW/client than with a Webcam--
especially ones like Creative that are BW sippers.

| You will find a few surprises, I have started streaming video with high
grade DV cams (cannon GL2's) and they are Huge bandwidth hogs, especially
when they have reflective surfaces in the cameras view. Example is a silk.
Another thing I found is, you have to have a really fast system to be able
to process all the video quick enough. I have a dual core 2GHz Mac book pro,
and it can barley keep up (I'm running a beta of the flash that runs on the
Intel based apple's, no blue issue anymore).
Thanks,
Alden.

This seems odd to me - why would a DV camera use more bandwidth?
Either way you're re-compressing the video - so the amount of
bandwidth used should be determined by your streaming settings and
have nothing to do with the camera. Is it because the little webcams
have less resolution, and therefore less detail, and the image is
therefore more easily compressed? It seems that even if this were the
case you'd still end up with the same quality/bandwidth in the end -
it would only be a bandwidth problem if trying to maintain the higher
resolution/quality of the DV camera.
Either way, I've got the HC1 which is essentially the same camera as
the A1 - it works fine with flash but you do need to switch it to DV
(not HDV) output via firewire, and you'll also need to change the
aspect ratio settings. I believe the A1 has a couple more options
than mine, but because the camera shoots 16x9 natively you can output
either a letterboxed version or an anamorphic one - it's possible the
A1 also does a cropped 4x3 option but I don't remember for sure (mine
doesn't).

| Hi quality video source like dv cam or some webcam
produce crisp image with a lot of information.
When you use setQuality(XX,0) in Flash Player,
you are setting indeed quantization level and not absolute quality,
this means that you decide how much information to crop out.
in this way, a detailed source image produce a bigger compressed
frame than a blurry image. The same is true for noisy images
that some webcams produce. Noise add "bad informations"
Try to experiment this using
a graphic program. Take a picture crisp and clear and compress
it to jpeg with an high quality setting, then apply to it a noise
filter and compress it again... you will get a bigger file, now apply
a gaussian blur filter and try compressing it again...you will get
a smaller file.
It is not a case that On2's encoder applies, for low bitrate stream,
an input image filter before final encoding stage.

| Hi again Evan...
Here are the results (so far).
1. DV--620k
2. iSight-443k
3. Orbit--446k
Naturally, my PC is having problems with the USB cams--the ones with
the lowest BW--however, they should come in lower than the ones I did
with the iSight and Orbit (both hoggy Webcams). Fabio's explanations
clarify it nicely--technically.
As soon as I figure out why my other Webcams went south and get them
working again, I'll get back to you.
HTH,
Bill

| Evan,
Good question. I really don't know the technical answers, but since
I'm surrounded by a slew of cameras, I can give it an empirical test.
I'll record a basic 10-count video with four different cameras:
1. Canon Optima DV (IEEE1394)
2. iSight (Firewire/IEEE1394)
3. Orbit (USB2)
4. Creative Pro (USB2)
1 & 4 are through a PC and 2 & 3 are on a Mac. The app uses non-
variable settings.
Back in a Flash.
