But you call yourself a prosumer....


They don't
care if the picture is noisy because of the 100dB gain, as long as they
have the memory of what happened. You as a prosumer care about the noise,
and will shoot preferrably with 0dB gain to keep the image nice and crisp.

I'm not a prosumer, because I'm not a pro. I've never shot video
professionally, never aspired to shoot video professionally and, except once
as a favor to a friend, never shot one foot of video that wasn't for my own,
very amateur and very common devices, e.g. vacation video, family
get-together, etc.

Prosumer does not equal a professional, but an amateur liking to work with
high quality equipment. There are professionals of course whihc use this
equipment as well, because for a 10th of the sum of a BVWxxx, they can
shoot their stuff, looking pretty good.

The most complicated composite I did in Premiere involved 12 animated video
layers with alpha channel. Anything more than that, or involving more
sophisticated control, I'll do in After Effects.

You're pretty brave :-) That would have been too much for me.

I'm also referring to inexpensive capture cards. My D-25 material ends up
as mpeg2 for distribution via DVD. I transcode to the highest possible
quality available to me in software transcoders priced under $1,000. My
DVDs look very, very good (technically). They do not look as good as D-25,
and the difference is very noticeable.

Then you need to tweak your material even more. In reality to make it look
good, you would need to adjust the parameters even per scene.

I have seen a few articles saying that you can squash down DV25 2.5 times
in bitrate in MPEG2 for equivalent quality. And that would make it, tada,
10Mbps.

I haven't seen those articles but, more to the point, I've seen my video.
As I said, the difference is readily noticeable.

Explain the difference.


Mini-DV can be converted to 5Mbps MPEG2 and keep the same quality
according to Sony's logic.

You're just making things up. Sony never said anything of the sort.

I was following their logic. I didn't say that it was their claim.

It's not their logic either. As I said, it's something you've made up -- a
strawman argument.

Uhm, that's what I said....
