An external time-base corrector (TBC) is the
next piece of equipment that most pros use when transferring
tapes to DVD. Even with a good VCR, issues can
arise that affect how a digitizer interprets a tape's video signal
(see our Video
to Digital page).
An external TBC corrects analog timing errors, which usually
appear as horizontal or vertical picture jitter, color shifts,
dropped frames, or ragged edges of lines. A TBC ensures that
a clean signal that is free from these defects is passed through
to the digitizing device. We use an external TBC for every tape
to DVD transfer to ensure that this occurs.
To improve picture quality even more, Timeless DVD then employs
a processing amplifier and detailer as well. These
pieces of video processing hardware can improve an analog video
picture tremendously, and generally offer better results than
using software filters on flawed digitized video.
The first tool, the processing amplifier, or "proc amp," is
also called a color corrector or video corrector. All proc amps
are geared to making manual adjustments to a video's contrast,
color, and hue. A proc amp can repair such issues as faded or oversaturated
color, red or green tint, a picture that is too dim or bright.
After you've transferred a tape via a proc amp and see the vibrant
images that result, you'll never want to do without it!
The second piece of hardware is a detailer, often called an image
enhancer. A detailer raises
the high frequencies of the video signal, a process that creates
better clarity and definition in the video prior to digitization.
In other words, a detailer appears to sharpen the image.
Timeless DVD uses both a proc amp and detailer whenever we copy
VCR tapes to DVD. Many video transfer services do not add proc
amps and detailers because they do entail more effort. But this
is another reason our work is
higher quality than what most companies offer.
