Converting to mp4 format

Question

I've created a project with a resolution of 945x630, and it
looks great. We are now wanting to convert these to an mp4 format
for iPhones. I'm using a tool called Moyea. When converting, the
default size is 480x320. The problem is the quality goes way
down...you can barely read what's on the screen. Is there anything
that can be done to keep the screen quality up, while converting to
a much smaller resolution? The 945x630 in Captivate is about as
small as I want to go.

Hi, and welcome to the User Community!
No, there is nothing you can do. Any resizing of more than
10-15% will nearly always degrade image quality (naturally, it
partly depends on what images or backgrounds are in the project). I
do not have a solution for you, but I do have a reason ... so maybe
an understanding is better than nothing at all.
Flash made its reputation by being enormously sharp and
*scalable*, and since Captivate outputs to a Flash SWF file, lots
of people assume it, too, would be scalable (sharp and clear at any
size). And therein lies the problem.
Flash maintains its scalability because Flash-created images
are vector-based. For our purposes, lets just say that vector
graphics are actually mathematical formulas, so when you change the
dimensions, all that is required is that the mathematical formula
be changed by the same degree, to maintain clarity.
On the other hand, Captivate works as a bitmap
editor/creator. Bitmapping is the methodology of assigning each
individual pixel (the smallest unit of measurement in a grid) its
own color identifier. So because Captivate converts everything to
bitmap images, when the image size is changed, the engine doing the
bitmapping has to interpolate what a new pixel should have as an
assigned color, or in the case of shrinking, what color should be
assigned to *smooth* the area where pixels are being squeezed
together.
A long-winded way of saying that - inside Captivate - *
you can't get there from here* (as they say in some parts of
the world). Sorry I don't have better news for you.
