RenderEvents

Render Events (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 pre-rendering those parts of a project where applied Fx seriously degrade playback performance or sometimes produce errors during final project render.

1. What to Render.

a. 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.

b. Loop region .  If selected, the loop region will be rendered to a New Track or just saved. 

c. Project .  The entire project will be rendered to a new track or just saved.

d. Regions .  If selected, all regions will be rendered to a New Track or just saved.

e. Selected Regions.      Opens a dialog where the user may select which regions to render.  Region names may be directly entered or edited and will be saved in the project.

 

f. In Loop .  If checked, only regions contained within the selection loop will be rendered

g.    Launches Otter NavBar which permits the user to navigate the timeline, select tracks and events, and set in and out points for render loop.

h. Same Track

(1) 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). 

(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.

(3) If this option is selected, the following warning appears.  The user may continue with the render or return to the GUI.  There is also a checkbox to disable this warning in the future.

i.  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.

j. No Resample.  Resampling is disabled for selected events.

2. What to Keep

a. Video Fx.  If checked, event Fx will be kept.  If video Fx or pan/crop settings are to be kept and the event added back as a Take, the following warning appears.  The user may continue with the render or return to the GUI.  There is also a checkbox to disable this warning in the future.

b. Pan/Crop Settings.  If checked, pan/crop settings will be kept. 

c. Fades .  If checked, fades will be kept.

d. 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 Premultiplied for the transparency to be applied.

e. 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.

f. 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.

g.  Velocity Envelope.  If checked,  the velocity envelope will be applied during render.

h. 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.

3. How to Save.

a. 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.

b. 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".

c. Save Only . If selected, the rendered media file will just be saved.  It will not be added back to the timeline. 

d. 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.

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

a. x264.  If the x264 button is selected, x264 options are made available and the Vegas render template selection box is disabled. 

b. Color Matrix .  Drop down list of the following options:   Auto - HOS attempts to maintain the same luminance and chrominance; None - Default with no conversion specified which is the same as the SD-TV option; HD-PC - PC.709 - HD coefficients, Full Range (0-255); SD-PC - PC.601 - SD coefficients, Full Range (0-255); HD-TV - Rec709 - HD coefficients, Limited Range (16-235); SD-TV - Rec601 - SD coefficients, Limited Range (16-235); RGB - Converts to 24bit RGB; and RGBA - Converts to 32 bit RGB for alpha channel.

c. x264 Render Templates . Drop down list of x264 render templates that can be chosen for proxy creation.

d. Vegas .  If the Vegas radio button is selected, the user must select the desired render template which is described in item #9.  Note that the gear and dropdown template selection box are disabled

e. Vegas Renderers . Drop down list of Vegas renderers that have been added as favorites.

f. Vegas Render Template. Drop down list of Vegas render templates for a specific renderer that have have added as favorites.

5.    When clicked, the following x264 rendering template window 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.

 

6.   Vegas Render Template Selection.  If the Vegas radio button is selected, the following window is shown.  A complete description of this window can be found in the help section describing Vegas Render Templates  in detail.

7. Where to Save. There are three options.

a. Specific Folder LocationRendered 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.  Previous saved folders are shown on a dropdown list.  To remove a saved folder, right-click and click on "Yes".   If "Create Project Name Sub-folder" is checked, a sub-folder will be created in that location with the name of the subfolder being the Project name.

b. 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.

c. 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.

d. 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.

e.   Left-click to re-enable the warnings pertaining to Same Track renders and keeping Fx or Pan/Crop settings.

f.   Opens the selected save folder in File Explorer.

g.    Opens the File Renaming Setup dialog where the user can customize the name of the rendered file.  Click  here   for detailed information.

8. After Render .

a. By-pass Fx . If checked, FX applied during render will be by-passed when the rendered event is added to the timeline.

b.  Reset Rates . Playback and Undersample rates will be reset to 1.0 once rendered event is added back to timeline. 

c.  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 .

 

d. Open Folder. Opens the folder of and selects the rendered file.

e.  Add Audio to TL. 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.

9. Options .

a. 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.

b. Preview Frames.  The number of frames that will be rendered if the Preview button is clicked.  

10. Render.  Starts the render.

11. Preview. The preview option enables the user to have a "quick-look" at just a few rendered frames beginning at the position of the cursor.  The number of frames rendered is controlled by the numeric up/down box in the Processing Options box.  A new track named "Preview" will be created which contains the rendered preview file.  The next time AviDub is launched, the Preview file and track will be removed from the project.

12. Cancel.  Closes the GUI without rendering.
