+In \textit{Drag and Drop} mode we can copy and paste edits containing plugins (see also \nameref{sub:copy_paste_behavior}). Start by selecting an edit (that contains plugins) with LMB and open the context menu with MMB. The possibilities offered are:
+
+\begin{description}
+ \item[Ctrl - c]: copy edits and plugins to buffer.
+ \item[Ctrl - v]: paste edits and plugins into the timeline (splice) at the Insertion point.
+ \item[Ctrl - b]: paste edits and plugins into the timeline (overwrite) at the Insertion point.
+ \item[Ctrl - Shift - p]: paste only the plugins into the timeline, at the Insertion point, keeping the original length (overwrite).
+ \item[Collect Effects]: copy only plugins into buffer.
+ \item[Paste Effects]: pastes the plugins into a selected target edit. The length of the plugins adapts to the length of the edit.

-Audio sampling (time data) is converted to a frequency spectrum using FFT (\textit{Fast Fourier Transform}). Since the \textit{Signal} contains only the background noise while the rest of the clip contains noise + audio to clean up, you get separate frequencies so you can subtract them to get the clean audio only. Set the Denoise Power dial in dB and choose the number of reference samples.

For example, if you record a voice with a microphone\protect\footnote{credit fary54}:
\begin{enumerate}
- \item You record 15 seconds of background noise (without talking). This is the \textit{Signal audio clip}.
- \item After 15 seconds, start the voice. This is the whole \textit{Noise Audio clip}
+ \item You record 15 seconds of background (without talking). This is represent the background noise that the filter uses as a reference..
+ \item After 15 seconds, start the voice. This is represents the recording whose filter should remove the background noise.
\item You stop recording.
- \item You place the FFT effect on the whole length of the recording (including the 15 seconds of signal noise).
+ \item You place the FFT effect on the whole length of the recording (including the 15 seconds of background noise).
\item Then place your cursor at the beginning of the 15 seconds. Enter the number of samples in the effect presets, e.g. 65536.
\end{enumerate}
-This has the effect of creating a keyframe that marks the beginning of the reference range which, in our example, ends at 65536 samples later.

During playback, the background noise is then automatically removed along the entire length of the effect.

-LV2 is an open standard for audio plugins using a simple interface with extensions which add functionality to support audio software. These plugins were written by external developers and provide additional audio effects to \CGG{} audio without having to change \CGG{} every time. Because the LV2 plugins are separate from \CGG{} Infinity, if one fails or does not perform as expected, \CGG{} should stay running and you will have to contact the programmers responsible for that plugin for a fix.
+LV2\protect\footnote{Optional Feature - OS dependent} is an open standard for audio plugins using a simple interface with extensions which add functionality to support audio software.

Because the LV2 plugins are separate from \CGG{} Infinity, if one fails or does not perform as expected, \CGG{} should stay running and you will have to contact the programmers responsible for that plugin for a fix.
Typically, a user OS has specialized package groups installed. It is difficult to create one build of \CGG{} to accommodate all potential LV2 plugins. Specifically for the \textit{Calf-Studio LV2 plugins}, you should install the \textit{Calf Plugins} package. The user’s computer must have \textit{gtk-2-runtime} installed, which seems to be automatically done already for most distros. For users doing their own builds, you can build \CGG{} without LV2 support by including \texttt{-{}-without-lv2} in the configure step. The default build is \texttt{-{}-with-lv2=yes} and requires that \textit{GTK-2-devel} must be installed or the build will fail and notify you. In addition for some newer distros, you will need to install
\textit{lv2-calf-plugins-gui}; for example Fedora version 32.

-The C41 plugin takes a $16\,bit C41$ digital intermediate negative film as input and outputs a positive image. It became necessary because $C-41$ negatives can fade or color-shift over time which was a problem early on. It is still important today because there is a large amount of documentaries, video clips, and other media out there that was shot on super $16$ film. This works for RGB-float, RGB, and also YUV variations.

There are two sets of data -- the scanned input values and your corrected values. Simple functionality of the plugin is to compute the data, transform to get corrected values, then apply that.
Normally threshold is very low when using a high slope. The two parameters tend to be exclusive because slope fills in extra threshold. The slope tries to soften the edges of the chroma key but it does not work well for compressed sources. A popular softening technique is to use a maximum slope and chain a blur effect below the chroma key effect to blur just the alpha.

-Chroma Key (HSV) (figure~\ref{fig:chroma-key-hsv}) replaces a color with another color or transparency using HSV variables; it is frequently used to remove a color from a video to composite with another image. This process is generally referred to as green screen or blue screen process (because of the color that is keyed out). More information: {\small \url{http://en.wikipedia.org/wiki/Chromakey}}
