High Definition (HD)
This relates to video, specifically the capture, creation
and broadcast size. Standard Definition (SD) is the older
format, which has a smaller frame
size and different format.
While HD doesn't have a fixed overall size even the smaller
forms are significantly higher quality than SD. A simple
comparison is the overall frame size in pixels that we
would use in 3D:
Standard Definition: 720x480 pixels, which is a total
of 345600 pixels, which is around one third of a "mega-pixel"
if you want to relate it to your digital camera.
High Definition: 1280x720 pixels (or higher), which is
at least 921600 pixels - close to a magapixel.
This increased frame size means a much sharper image but
also requires more advanced technology for the broadcast
and the viewing.
Almost all video producers have switched to high-definition
and many big budget movies are now shot and edited in high-definition
too. HD frame sizes for Hollywood movies are much larger
than those we see on our TV screens so they have plenty
of quality and image size for special effect overlays and
transposing to films that can be played in regular cinemas.
High Definition 3D Animations
Archiform 3D switch to HD as a standard in 2008, considering
that both the delivery and the viewing technology was out
there enough to ensure that the extra work and processing
time needed to create HD 3D footage was warranted. Fortunately
technology in our render farm improved
as well, so we were able to handle the significantly longer
render times.
