Rendered Effects

Besides the Realtime effects, as has been described in the previous sections, another type of effect is performed on a section of the track and the result stored somewhere before it is played back. The result is usually pasted into the track to replace the original data. The rendered effects are not listed in the resources window but instead are accessed through the Audio → Render effect and Video → Render effect menu options. Each of these menu options brings up a dialog for the rendered effect. In the Select an effect dialog is a list of all the realtime and all the rendered effects. The difference here is that the realtime effects are rendered to disk and not applied under the track. Rendered effects apply to only one type of track, either audio or video. If no tracks of the type exist, an error pops up.

A region of the timeline to apply the effect to must be defined before selecting Render effect. If no in/out points and no highlighted region exist, the entire region after the insertion point is treated as the affected region. Otherwise, the region between the in/out points or the highlighted region is the affected region. The tracks to apply the rendered affect to, need to be armed, other tracks are ignored. The rendered effect processes certain track attributes when it reads its input data but not others. Transitions in the affected track are applied, but nudge and effects are not. This allows the new data to be pasted into the existing position without changing the nudge value.

How to use a rendered effect

• Highlight an effect in the list (Select an effect) to designate it as the one being used.
• Define a file to render the effect to in the Select a file to render to box. The magnifying glass allows file selection from a list.
• Select a file format which can handle the track type. The wrench allows configuration specific to the file format.
• There is also an option for creating a new file at each label. For example, if you have a CD rip on the timeline which you want to divide into different files, the labels would become dividing points between the files if this option were selected. When the timeline is divided by labels, the effect is re-initialized at every label. Normalize operations take the peak in the current file and not in the entire timeline.
• Finally there is an insertion strategy just like in the render dialog. It should be noted that even though the effect applies only to audio or video, the insertion strategy applies to all tracks just like a clipboard operation.
• When you click OK in the effect dialog, it calls the GUI of the effect. If the effect is also a realtime effect, a second GUI appears to prompt for acceptance or rejection of the current settings.
• After accepting the settings, the effect is processed.
