RenderEvents (RE) enables the user to render timeline events, a loop region, regions, or the entire project and then add the rendered file back to the timeline as either a Take or on a new track.  There are options to keep or remove most event properties.  The user has the choice of using internal Vegas encoders or direct x264 encoding.  RE can be useful for prerendering those parts of a project where applied Fx seriously degrade playback performance or sometimes produce errors during final project render.

What to Render

  • Events .  Multiple events may be selected from a single track. The rendered media file may be added back to the event as a Take, rendered to  New Track or just saved.
  • Loop region .  If selected, the loop region will be rendered to a New Track or just saved. 
  • Regions .  If selected, all regions will be rendered to a New Track or just saved.
  • Project .  The entire project will be rendered to a new track or just saved.
  • Same Track .
    • Unchecked.  Selected events or events within the loop, region or project will be copied a new temporary track where fades, video Fx, pan/crop settings, etc. will be removed unless checked in the What to Keep info box (#2). 
    • Checked.  No temporary track will be created and no events copied.   Video Fx, pan/crop settings, etc. will still be removed unless checked in the What to Keep info box (#2).  This option is useful for pre-rendering certain Fx such as Mercalli stabilization where copying to a new track and maintaining those Fx are not possible.  During the render, selected track is Soloed, thus muting other video tracks.
  • All Tracks .  This option is available only if Same Track is checked.  If checked, all tracks will be included in the render unless muted by the user prior to rendering.  It is useful for pre-rendering events or loops  where the user wants to add titles or other graphic Fx such as Hitfilm to the pre-rendered video.
  • No Resample.  Resampling is disabled for selected events.

What to Keep.

  • Video Fx.  If checked, event Fx will be kept. 
  • Pan/Crop Settings.  If checked, pan/crop setttings will be kept. 
  • Fades .  If checked, fades will be kept.
  • Playback Rate.  If checked, a changed playback rate will be applied during render.  If playback rate is 1.0, there is no need to check this box.
  • Undersample Rate. If checked, a changed undersample rate will be applied during render.  If the undersample rate is 1.0, there is no need to check this box.
  • Velocity Envelope.  If checked,  the velocity envelope will be applied during render.
  • Alpha Setting.  If checked, the alpha property of the selected event will be applied to the rendered event once added back to the timeline.  This can be useful if one wants to pre-render a title or Hitfilm graphic Fx using a codec that supports alpha such as Quicktime Animation.  Otherwise, the default Alpha setting of None must be manually changed to Pre-multiplied for the transparency to be applied.
  • Original Audio. If checked, the audio for the selected event will be rendered.  A copy will be made and all fades and FX removed.  If unchecked, audio may still be included by muting unwanted tracks.  No copy will be made and fades and FX will not be removed.

How to Save

  • Add as Take.  This option is available only for Event renders.  If selected, the rendered media file’s videostream will be added back to the original video event as a Take.   If Add Audio Back is checked, the rendered file’s audio stream will be added as a Take to the selected event’s audio track.
  • Render to New Track. This options is available for all types of renders.  If selected, the rendered file’s videostream  will be added to a new track entitled “Rendered Video”.  If Add Audio Back is checked, the rendered file’s audio stream will be added to a new track entitled “Rendered Audio”.
  • Save Only . If selected, the rendered media file will just be saved.  It will not be added back to the timeline. 
  • After Render .
    • By-pass Fx . If checked, FX applied during render will be by-passed when the rendered event is added to the timeline.
    • Reset Rates . Playback and Undersample rates will be reset to 1.0 once rendered event is added back to timeline. 
    • Play Media .  If checked, the rendered file will be opened in Media Player Classic – Home Cinema for immediate playback. A complete description of this dialog may be found in  OtterPlay .
    • Add Audio Back. If checked, an audio track will be added for events  rendered to a New Track or an audio take added for events Added as Take.

What to Load

  • Last Used .  By default, RE loads the same settings that were used the last time the script was executed.
  • Default .  Loads default settings.

What to Add

  • Extra Frames .  Number of frames added to rendered event.  This can be useful when using some long-gop renderers that occasionally drop the last frame such as XAVC-S.
  • File Tag . If checked, a file tag will be added.  It is any additional text that you want to  be included in the rendered events file name. It can  be useful for tracking what FX have been applied  during a render.  A Media Bin will also be created using the same name and renders will be added to that bin.

Render Options.  The user may choose to use internal Vegas rendering or direct x264 rendering.

  • Vegas .  If the Vegas radio button is selected as shown, the user must select the desired Vegas render template.  Note that the x264 gear and dropdown template selection box are disabled.
  • x264.  If the x264 button is selected, x264 options are made available and the Vegas render template selection box is disabled.
    • Template Selection.  The x264 Render Template may be selected directly from the drop down list without opening the x264 Encoder Settings dialog.
    •  When clicked, the x264 Encoder Settings dialog is shown.  Note that the same window can be loaded when x264 rendering is selected in AviDub and ProxyAssist.  Templates created in one script may be used in other scripts as well.  A complete description of this window may be found in the help section describing x264 Render Templates in detail.

Where to Save

  • Specific Folder Location .  Rendered media files are stored in a specific folder selected by the user.  A left-click on the folder icon opens the browse folder dialog from which the location is selected or a new folder created.  If “Create Project Name Sub-folder” is checked, a sub-folder will be created in that location with the name of the sub-folder being the Project name.
  • Sub-folder of Project Folder. Rendered media files are stored in a sub-folder in the  folder where the Vegas project is located.  The name  of the sub-folder may be entered into the textbox on  the right.
  • Sub-folder of Media File Folder .  Rendered media files are stored in a sub-folder in the  folder where the media file is located.  The name of  the sub-folder may be entered into the textbox on the right.This option is available only for event renders. .
  •  Left-click to re-enable the warnings pertaining to Same Track renders and keeping Fx or Pan/Crop settings.
