PICTURE PROFILE
Information essential for making the most of PICTURE PROFILE
Difference from image processing using nonlinear video editing software
PICTURE PROFILE adjusts colors and the vividness of the image
upon recording. You can make similar adjustments by using
nonlinear editing software after shooting. But there are the
following differences.
To fit massive amounts of image data in a limited memory
capacity, most camcorders compress image data when
recording. No matter how advanced a compression format is,
any data compression inevitably deteriorates image quality
somewhat. Applying sharpness, gamma curve correction and
other video effects to recorded images by using nonlinear
editing software worsens the image condition further by
processing already deteriorated images. For example, if video
compression leaves the image with poor contrast or block
noise in some areas, applying video effects often make the
problems more noticeable.
Because PICTURE PROFILE processes video signals before
compressing, it changes the gamma curve and corrects colors
before image quality is damaged by compression. This makes
What to do on the scene
If you are working on a project with ample time for editing or
a short piece, you probably should record the image as flat
as possible to allow for all kinds of post-production image
processing and color adjustments.
If you are working on a project with a tight deadline or a long
piece, on the other hand, you can dramatically reduce the
amount of post-production image processing and enable highly
efficient production by dialing in settings to record the video as
close to the vision of the finished image as possible. Showing
the image being recorded to the director and crew as close to
it possible to carry out highly precise image adjustments while
keeping the quality of the subject intact.
It should also be noted that recording images with proper
contrast is crucial. If image contrast in dark and bright areas is
not recorded right, underexposed dark and overexposed white
areas will have no gradations. This means you cannot change
image contrast properly later on with nonlinear editing software
no matter how hard you try because there will be no gradations
to work with.
Even if you intend to process your video with nonlinear editing
software later, it is important that you record your image in the
right way. Nonlinear editing software is a very powerful tool, but
can't fix everything. If you adjust various settings to make sure
your video is recorded in a way that is as close to your ideal as
possible, you will be able to create a video that will be closer to
what you have in mind with minimal processing via nonlinear
editing software. It will also keep rendering time short and
make video editing work more efficient.
the tone of the ideal finished image as possible on a display
monitor will greatly boost morale on the scene. By shooting
video in a manner that boosts the atmosphere on the scene,
you will be able to make a major impact on the quality of the
finished work.
In order to avoid the problems with nonlinear editing described
in the previous section, and also to create pieces that make the
most of the compact camcorder's mobility, please fully utilize
PICTURE PROFILE and record the image at proper settings.
