Object Removal - Blackmagic Design Cintel Manual De Instalación Y Funcionamiento

9 If you've had to use a high spatial NR luma or chroma threshold setting to reduce noise
visibly, and areas of detail look a bit chunky or aliased, you can choose a larger setting
from the 'radius' menu to enable a more detailed analysis of the scene.
This will result in higher visual quality, but larger NR radius settings are more processor-
intensive and may reduce real-time performance if you don't have adequate GPU
resources available to your system.
10 If you've found suitable noise reduction settings, but the result is too aggressive and
makes the image appear too processed, you can try raising the spatial NR and/or
temporal NR blend parameters to fade between the noise reduction added by each set
of controls, and the image as it was before you added noise reduction.
Try Applying Temporal NR First, then Applying Spatial NR
Because temporal NR analyzes multiple frames for its noise isolation, it tends to be better at
preserving detail accurately in regions of the image where there's little motion. If you try
applying temporal NR first and get a successful result, even if only in part of the image, you may
reduce how much spatial NR you have to apply, thus improving the overall quality of your
final result.
Keep in mind that while temporal NR does a great job in unmoving parts of an image but is less
effective when dealing with subjects in motion, spatial NR can reduce noise everywhere in the
frame falling below its threshold, even when there's motion. Ultimately, a combination of the two
is almost always going to be a winning combination.
Spatial NR Radius, How Large Should You Go?
Larger NR radius settings can dramatically improve the quality of high-detail regions in shots
where you're using aggressive spatial noise reduction, but it's not necessary to always jump to
the large radius setting, which provides the highest precision. In many cases, when evaluating
an image that you're applying noise reduction to, you may not be able to perceive the additional
quality. You'll waste processing time on an unnecessary level of correction.
It's a good idea to evaluate the full-frame image on a large enough display to see the noise
you're working on within the viewing context of the intended audience. Zooming really far into a
clip while applying noise reduction may encourage you to use higher quality settings than are
necessary because an excessively enlarged detail of an image lets you see subtle changes that
you wouldn't notice at actual size.

Object Removal

The object removal plugin is best used in the 'color' page, and uses the DaVinci Neural Engine
to attempt to remove an object in the frame as automatically as possible. This plugin works best
when removing a moving object that passes over a temporally stable background, or dirt on the
lens of a shot where the camera is in motion. Smaller objects get better results than larger
objects, but your results really depend on the footage. Here's a simple procedure that shows
how to do this.
To remove a moving object from a clip:
1 In this example, a drone is flying through a long shot that's being simultaneously
recorded. We'll remove the drone using a window to identify the feature to be removed
using the object removal plugin.
