Hi all,

I'm using Ahead's DVD MovieFactory 5. I've got a video that
is precisely 720x480... not 640x480, nor 720x540, nor 720x405.
It is a true 3:2 video and I want to make a DVD from it
that's playable on a regular NTSC TV.

However whenever I try to attempt this, the DVD that is created
is cropped on common DVD players to 640x480. Ahead's software
only permits 4:3 and 16:9 but still, I would have thought it would
make a 720x480 DVD that would tell players to use it correctly.

Is there perhaps a cheap or free program that can handle
making a usable 3:2 DVD?

Thanks.

If that is the case, what you're seeing isn't 640 x 480.
what you're seeing is the result of something called overscan (search
this term on Wikipedia for more info) which happens on every TV ever
made. Even modern LCD & plasma sets aren't immune to this problem.
In a nutshell, depending on your TV set, the outer 5% to 10% (more on
older sets) of your image will be cut off - and, short of an alignment
at a repair shop, there's nothing you can do about it.
The only solution is to be aware of this issue and pay more attention to
your image at the time of shooting.

[I hope it is not too early in the morning to correctly figure
out what you are trying to do...;-]

I think you are confusing some pixel proportions with picture
proportions. Standard format DVDs are written in 720x480
(NTSC, 4:3), or sometimes 704x480, but the final viewed
product is 640x480 on standard definition NTSC TVs (minus
the overscan area pointed out by RC), unless the format is
16:9. This happens for two reasons. Digital editing is done
with non-square pixels, giving the correct 4:3 proportion (or
16:9) at output from 3:2 picture pixel proportions (if the pixels
were square), and with analogue TVs, the vertical line count is
a fixed 480 (NTSC), but the horizontal resolution (not pixel
count) is determined by available/readable frequency response
(more information squeezed into the longer dimension of the
picture makes for a sharper picture, not a proportionally wider
one...). If you succeeded in viewing the 720x480 (3:2) picture
as 3:2, you would not like it since everything would look
stretched horizontally. If for some reason you really want a
3:2 picture, you must crop with black bars the displayed
picture at the top and bottom - and many programs can do
this...

720x480 is legal DV spec, all NTSC footage shot with a SD camcorder is
720x480.
you don't want to do a thing to it.

no it's not.
it's 720x480
640x480 is D1(720x480) video with the pixel aspect taken into account to be
shown on computer monitors.

with overscan.. it's 640x480 on NTSC TVs.

I should have said 4:3 without specifying pixel count (except
that can be reasonable along the vertical side, since there are 480
scan lines in NTSC). In the horizontal direction, the 4:3 proportion
is equivalent in appearance to 640 pixels wide, but it can be any
number, and with analogue displays (as SD TVs are), the pixel
count (the pixels are generally not square if the count is other than
640) affects visual resolution (which is different from pixel-count
resolution). There are formats that are far from 640x480 (even
square) that display in the correct proportions on SD NTSC TVs.

486 !


In the horizontal direction, the 4:3 proportion

profesionals and consumers by how many lines they had in their video
(486 for all pro equipment 480 for consumer equipment ). It has gotten
more blured lately because the DV standard (officially a consumer format)
has been embraced by a many professionals.

use 720 x 480 as the standard. If the pixels were square the resolution
would
be 640 x 480, but that tends to look a bit fuzzy. As a result we mostly use
a
resolution of 720 x 480 or 720 x 486 in some profesional equipment. Yes
that is the same as pixel count. Analog video was never directly limited by
a
horizontal pixel count. The horizontal resolution was only limited by the
quality
of the equipment. Composite video is limited to accomodate the color
subcarrier
that is used to modulate the color information onto a black and white video
signal.

I'm amazed to learn this. I just assumed it was 720x480 square pixels,
so I created a film based on that assumption. It's mostly a montage
of digital photos, whose pixels are square.

However I should note that I did try to feed a 640x480 film into
Ahead's DVD MovieFactory, and the resulting DVD image was expanded so
that
a lot of the photos' edges were off-screen...
In fact, I had to add black borders to make the 640x480 into 720x480
and then it was mostly on-screen, except there was some loss
vertically.
Anybody know why DVD MovieFactory would mess that up?

Thanks.

It probably doesn't...
I think you are still not getting it. For SD, the vertical scan
line count (usable as vertical pixel count in both analogue and
digital displays - well, except pro gear, which may give you
486...;-) is generally 480 (NTSC). The horizontal count
doesn't affect anything but visual resolution, whether 720
(DVD), 640 (older analogue formats), 480 (S-VCD), or
320 (VCD - but the vertical count would be 240 with this
low resolution format). The visual proportions in the frame
will remain a correct 4:3 (with no dimensional "stretching")
on analogue TV displays, but the higher number of pixels
in the horizontal direction can translate into a sharper-looking
picture on good TVs. This is not true if SD images are
displayed on a digital system with anything other than
non-square pixels being used (to compensate for the visual
proportion "stretching"). If you look at what you have
done, you may find that the photos are stretched somewhat
in one direction, making them look odd. In addition, if your
original photos are 3:2, you must include bars so that you do
not lose parts of the image as seen on SD TVs - and since
CRT SD TVs cut off part of the image all around, if you
want to show the whole photo, you must add space all
around the photos to compensate for this...

NTSC is 486 DV is 480.

Can't confuse the two.
