-Allows you to apply an alpha value (transparency) to one or more tracks or one or more edits. Being also keyframable, it allows an excellent variety and possibility of use in the most disparate occasions.
+Allows you to apply an alpha value (transparency) to one or more tracks or one or more edits. You can use the slider or have maximum precision by entering numbers in the input box. You can use the \textit{Clear} button to reset to the default value. Being also keyframable, it allows an excellent variety and possibility of use in the most disparate ways.
\subsection{Auto Scale}%
\label{sub:auto_scale}
To brighten a dark shot, or add light, use this plugin. Do not overuse the effect or you risk degrading your video quality.
The \textit{Brightness} slider moves up or down the values of the entire channel and corresponds to the \textit{Master Offset} of the various grading programs.
-The \textit{Contrast} slider expands or narrows the brightness values of the entire channel; corresponds to the use of the \textit{cursors} (small triangles) in the \textit{Histogram} plugin. Clear icons are present to reset its slider to default without affecting others.

Use the effect along with keyframing to brighten a long shot that is dark at the beginning but bright at the end. Generally you will want to change the brightness and contrast about the same amount (for example -- brightness $28$, contrast $26$) so that your original colors are kept intact. This effect is also keyframable (figure~\ref{fig:brightness}).
\subsection{BurningTV}%
\label{sub:hue_saturation}
\index{hue saturation}
-With this effect you can change hue, saturation and value. The parameters are modified using 3 simple sliders. The \textit{hue} control shifts the colors circularly in the color plane, normally resulting in false colors. The \textit{saturation} control can be used to reduce color footage to black and white. The \textit{value} control makes any given colors more bright or more subdued. Clear buttons are present to reset its slider to default without affecting others.

\subsection{Live Video}%
\label{sub:polar}
\index{polar}
-The \textit{Polar} effect bends and warps your video in weird ways. Mathematically, it converts your video from either \textit{polar} coordinates to \textit{rectangular} coordinates, or the reverse.

\subsection{Posterize}%
\label{sub:posterize}
\label{sub:rgb-shift}
\index{rgb shift}
-Most cameras take the light coming into the lens, and convert that into $3$ sets of numbers, one for Red (R), one for Green (G), and one for Blue (B). Some of the older cameras were composed of $3$ sensors and originally the RGB sensors were on $3$ separate planes and had to be aligned. If they were misaligned in the video, you can use \textit{RGBShift} to get them realigned. To move a specific color up/down, modify the \textit{dy} value using the slider bar in the RGBShift window. To move a color left/right, modify the corresponding \textit{dx} value. Clear buttons are present to reset its slider to default without affecting others. Note that the current values of the RGBShift are maintained in the \texttt{.bcast5} defaults file and will be retained across sessions. If using the YUV color space, you will want to use \textit{YUVShift} instead. Figure~\ref{fig:rgbshift} showing RGB shift before and after.

+to interpolation. The interpolation algorithm is simply the slope of a linear curve. This plugin is keyframable and the \textit{Interpolate} option works between keyframes. A simpler and more handy version is the \textit{Speed PerCent} plugin.
\subsubsection*{Stretch}%
\label{ssub:stretch}
\textit{Example:} you have a clip that you want to put in slow motion. The clip starts at $33.792\, seconds$ and ends at $39.765$. The clip is $5.973\, seconds$ long. You want to play it at $\frac{4}{10}^{ths}$ normal speed. You divide the clip length by the playback speed ($5.973\div0.4$) to get a final clip length of $14.9325\,seconds$. You create an in point at the start of your clip: $33.792\,seconds$. You put an out point $14.9325\,seconds$ later, at $48.7245\,seconds$ ($33.792 + 14.9325$). You attach a \texttt{ReframeRT} effect, set it to $0.4$ and stretch. You change the out point at $48.7245$ to an in point. You start your next clip after the slow motion effect at the $48.7245$ out point. You can do this without making any calculations by first applying the effect and then lengthening or shortening the bar to where the stretched movie ends.
-Now in the timeline we have the affected part of the plugin where we see the slow/fast effect, and the continuation of the timeline from where the plugin ends. We then have to select the interval on which the plugin acts and render it or transform it into a nested clip or nested asset. In this way we can replace or overlap it with the part of the timeline that originally included all of the part we wanted to slow down/speed up.

\item ReframeRT uses the fps indicated in \texttt{Settings $\rightarrow$ Format $\rightarrow$ fps} project and not the \texttt{fps} of the assets.
\item It can be associated with Nested Clips.
- \item As an alternative to ReframeRT you can use the \textit{speed curve}, or change the framerate in \texttt{Resources $\rightarrow$ info} and in the \texttt{Project}.

\subsection{Shift Interlace}%
\label{sub:shift_interlace}
The \textit{fill} point is a marker point, and not really part of the curve. That point identifies the inside of the loop. It can also be used to identify the outside of the loop in order to fill that. The loop is created by drawing a line from the last point to the first point in the curve. The line of this last segment is from the last point of the curve. If there are isolated loops in the curve (it is self intersecting) then you will be able to use multiple fill points to fill these regions.
+\subsection{Speed PerCent}%
+\label{sub:speed_per_cent}
+\index{speed percent}
+
+It works like the \texttt{ReframeRT} plugin in \textit{Stretch} mode. The interpolation algorithm is simply the slope of a linear curve. It allows you to change the speed of the video track, or an edit, or a region of the track quickly and intuitively. There are presets to set the speed to 100\% (default) or 25\%; 50\%; 200\% and 400\%. Or we can enter the value directly in the text box or use the slider until the desired value is reached. \textit{Interpolate} option works between keyframes. It requires setting the right limits for applying the effect and then rendering that region, or turning it into a nested clip, which will replace the original one.

\label{fig:yuvshift}
\end{figure}
-This effect is used for YUV input video from older cameras using $3$ sensors. It is possible to have misalignment of the $3$ sets of numbers: \textit{Y}, which represents the luminance or brightness component, and for \textit{U} and \textit{V} representing the chrominance (color) components. If they were misaligned in the video, you can use \textit{YUVShift} to realign. To move a specific component up/down, modify the \textit{dy} value using the slider bar in the RGBShift window. To move a component left/right, modify the corresponding \textit{dx} value. With the Clear buttons we can bring the slider to default values without affecting the other parameters. If you are using an RGB color space, you will want to use the \textit{RGBShift} effect instead.
