That's actually the standard quoting practice in newsgroups - at least
with longer messages that deal with multiple subtopics. There's nothing
unclear about it. On the contrary, dividing a longer message in multiple
quoted segments (and the related comments) makes the text more
conversational in its nature and easier to read.

Note that technically, you're not only placing your answers _between_
someone's text. More to the point, you're placing your text _below_ the
segments which you're commenting. So what you're doing is actually
exactly the same thing as with shorter messages: In shorter messages,
too, you write your comments _below_ the quoted part which you're
commenting. It doesn't matter whether you only have a single quoted
segment in your message or several quoted segments - the "quote +
related comment" principle stays the same.

Hmm. I don't see Frank claiming the camera _wasn't_ digital. In the
above, he is merely pointing out that whoever originally shot the
material was using suboptimal audio settings.

OK, now we're getting to the gist of the problem. That "720h 480v" is
the real reason for stuttery, flickery output. In your export settings,
you're using "NTSC" frame resolution and "NTSC" frame rate for "PAL"
material.

Vertical scaling (576 -> 480) breaks down the structure of interlaced
video unless special precautions are taken. Temporal rate conversion (25
fps to 29.97 FPS) isn't going to make things any better, either - it
will introduce "beating" in the motion. These are the main reasons why
your results look so bad.

As suggested in an earlier message, try exporting the video in DV format
(instead of using the Cinepak codec), with the original frame rate of
the source clips (25 fps) and the original resolution of the source
clips (720×576). That should help.

1) Choose "Project" -> "Project Settings" -> "General". Set "DV
Playback" for "Editing Mode".

2) Choose "Project" -> "Project Settings" -> "Video" and make sure you
have something like "Microsoft DV (PAL)" selected in there, that the
resolution is set to 720×480, and that the pixel aspect ratio is set to
"D1/DV PAL".

3) Choose "File" -> "Export Timeline" -> "Movie" and click "Settings".
Choose "Video" and make sure you're using the "DV PAL" compressor. The
audio should be set to 48000 Hz 16-bit, with 1 second interleave. Click
OK. Try exporting the movie now and see if you still have problems with
it.

You might also want to take a look at "Project" -> "Settings Viewer",
which gives an overview of your project and export settings.
