Because a 3D project timeline consists of multiple synchronized mask, video and audio tracks, and Vegas will incorrectly assume that you are A/B editing, the normal editing functions do not work as desired.
Normally, editing in Vegas consists of splitting events and deleting unwanted events on individual tracks. This does not work for 3D timelines because they are composed of six interrelated tracks: L Mask, L Video, L Audio, R Mask, R Video and R Audio.
The 3D Timeline Utilities process 3D events on all six of the 3D timeline tracks.
Typical video editing consists of removing unwanted sections from the raw video input. The Make3D_Split and Make3D_Delete tools are included with, but separate from the Make3D toolkit. This is so the Split and Delete 3D timeline editing functions can be added to the Vegas toolbar for fast access.
Because all events in the six 3D timeline tracks must remain synchronized, the Make3D_Split and Make3D_Delete tools validate all 3D timeline events before executing. If 3D timeline problems are detected, the Split and Delete tools will not function, but will display a dialog that describes the detected 3D timeline problem.
Because the Shift values for a video pair are copied to new events created by splitting an event on the timeline, it is best to use the “Adjust 3D Pan Crop” tool to adjust the 3D window for events in the 3D timeline before doing basic Split and Delete editing.
Move the Vegas cursor to the desired timeline position and then run the Make3D_Split tool. The corresponding events in the L Mask, L Video, L Audio, R Mask, R Video and R Audio tracks will be split at the cursor position. Events in other tracks will not be affected. All of the selected events in the L Video track will be cleared and the left event that was split will be selected. The Make3D_Split actions can be undone using [Vegas / Edit / Undo Run Script].
Select an event in the L Video track and then run the Make3D_ Delete tool. Events selected in other tracks have no effect, and the first selected event controls the removal of synchronized events from the L Mask, L Video, L Audio, R Mask, R Video and R Audio tracks. The Make3D_ Delete script performs a ripple delete, and later events in the 3D timeline are moved forward to fill the deleted time gap. The cursor will be repositioned to the point where the selected event was deleted. Events in other tracks will not be affected. The Make3D_ Delete actions can be undone using [Vegas / Edit / Undo Run Script].
Select an event in the L Video track and then run the “Adjust 3D Pan Crop” tool. Events selected in other tracks have no effect. If multiple events are selected, only the earliest timed event will be processed.
When the “Adjust 3D Pan Crop” tool is run a second Video Motion Keyframe is added to the end of the selected event. This end Keyframe is used for dynamic panning and zooming. Because simple 3D window adjustment and cropping do not require different End values, changing the Start values will automatically change the corresponding End values. Make all your Start value adjustments before making any End value adjustments.
The “<< Cursor” and “Cursor >>” buttons let you look at the current 3D Pan Crop values and the selected event Start and End frames. This is useful before and after making adjustments.
The “Reset” button resets the Zoom values to 1.0 and the Position values to 0.5, but does not change the Shift values.
The “Test” button sets the Zoom and Position values to create a dynamic PanCrop.
The “<< Event” and “Event >>” buttons let you move to the prior or next event.
The Flip checkboxes are used to correct mirrored or 180 degree rotated video files. The Flip Left X checkbox horizontally mirrors the left input file. The Flip Left Y checkbox vertically mirrors the left input file. The Flip Right X checkbox horizontally mirrors the right input file. The Flip Right Y checkbox vertically mirrors the right input file. Using both Flip X and Flip Y together will handle upside down (180 degree rotation) input files.
WARNING: There is no support for 90
or 270 degree video file rotation.
Regardless of the final output format you are going to
render, it helps to wear Red/Cyan Anaglyph glasses when using the “Adjust
3D Pan Crop” tool. Use the “Convert 3D Timeline Format” tool to
change the 3D timeline to Anaglyph Red/Cyan while editing the 3D
timeline. Before rendering, convert the 3D timeline to the desired output
format. You only need to wear the Anaglyph glasses when checking the 3D
window and Pan Crop settings. Most of the basic editing can be done without
wearing the glasses. Regardless of the Preview quality settings, make
sure to set the Preview size to Auto so you can see the entire 3D
window.
When you ran the “Find Alignment” tool the Shift X and Shift Y (and Start Frame) values for the left and right video files were saved in an alignment file. When you ran the “Create New 3D Timeline” or “Append 3D Pairs to Timeline” tools the settings in the alignment file were used to create the initial Pan/Crop keyframes.
You can re-adjust the 3D window for an event in the timeline by changing the Shift X and Shift Y values. Because the Shift values for a video pair are copied to new events created by splitting an event on the timeline, it is best to adjust the Pan/Crop values for events in the 3D timeline before doing basic Split and Delete editing.
The Shift Y value is used to correct vertical camera misalignment. With the Anaglyph glasses off, adjust the Shift Y value until the left and right videos are vertically aligned.
Adjusting the Shift X value moves the 3D window closer or farther away. This is a more artistic adjustment and depends on the final display device size and the position of objects in the 3D scene. Setting the proper 3D window for large display devices is more exacting than for smaller displays. Aside from the artistic goal there are two competing factors for the 3D window adjustment.
First, for large displays you do not want the left and right eye separation for the furthest objects in the scene to be greater than a few inches.
Second, you do not want objects in the scene that are in
front of the 3D window to be cut by the edges of the 3D window.
Adjusting the Shift X and Shift Y values can cause black bars around the edge of the 3D window. If you use Zoom values greater than 1.0 to select a desired region within the original image, then the selected region is expanded to fill the entire frame. The greater the Zoom value; the fuzzier the final result. Zoom values less than 1.0 reduce the 3D window size and do not degrade the final resolution.
Cropping the 3D window consists of selecting the desired Zoom and Position values.
The minimum Zoom value of 0.1 reduces the entire 3D window to one tenth of the original size.
The maximum Zoom value of 10.0 selects a region one tenth of the original 3D window and expands the region to fill the entire frame.
If the Zoom value is greater than 1.0 then the Pan Crop Group values control where the expanded region is extracted from the 3D window.
If the Zoom value is less than 1.0 then the Pan Crop Group values control where the reduced 3D window is placed on the output frame.
The default Pan Crop Group values of 0.5, centers the selection region.
The minimum Pan Crop X values of 0.0 moves the selection region to the Left edge.
The maximum Pan Crop X values of 1.0 moves the selection region to the Right edge.
The minimum Pan Crop Y values of 0.0 moves the selection region to the Top edge.
The maximum Pan Crop Y values of 1.0 moves the selection region to the Bottom edge.
For ordinary cropping, the Start and End values should be the same!
1) Select event in L Video track
2) Open the “Adjust 3D Pan Crop” tool
3) Set the Start Zoom to 1.5
4) Set the Start X to 0.2
5) Set the Start Y to 0.7
When played the event should be cropped to a lower left region of the original 3D window.
Experiment with different Start values, and observe
what happens!
Dynamic panning and Zooming requires setting the End values different from the Start values. The Start values apply to the first frame in the event, and the End values apply to the last frame in the event. The Pan Crop values are smoothly adjusted between the Start and End values for each frame of the event. If the Make3D_Split tool is used to split an event, then the adjusted Pan Crop values at the split position are copied to the split events.
6) Select event in L Video track
7) Open the “Adjust 3D Pan Crop” tool
8) Set the Start Zoom to 2.0
9) Set the Start X to 0.0
10) Set the Start Y to 0.0
11) Set the End X to 1.0
12) Set the End Y to 1.0
When played the event should pan from the upper left to the lower right.
1) Select event in L Video track.
2) Open the “Adjust 3D Pan Crop” tool.
3) Set the End Zoom to 3.0
4) Set the End Y to 1.0
When played the event should zoom to the upper center.
Experiment with the Start and End settings to create advanced panning and zooming.
Because of possible black bars around the 3D window, crossing value 1.0 between the Start Zoom and End Zoom values may result in undesirable artifacts.
Although Vegas can support many Video Motion Keyframes in a single event, Make3D is restricted to just the Start and End frame positions. To mimic the Vegas capability you can split events and use the “Adjust 3D Pan Crop tool for each split event.

Although the Find Audio Clicks tool was used to select the start frames for the left and right video clips, the left and right camera synchronization can drift over time. You can compare individual frames or zoom in on the Left Audio and Right Audio tracks to check the camera synchronization. The Sync Left and Sync Right tools allow you to drop single frames from the 3D Timeline to correct the synchronization.
Split the 3D Timeline events at the current cursor position
and delete a frame from the beginning of the new left video event and delete a
frame from the end of the new right video event.
Split the 3D Timeline events at the current cursor position
and delete a frame from the beginning of the new right video event and delete a
frame from the end of the new left video event.
Using time range selections to
perform advanced editing is easier and safer than individually processing
events on all six 3D timeline tracks.
Unfortunately, this means you
should perform all of the editing functions on the 3D timeline, such as “Cut”,
“Copy”, “Paste”, etc., before adding additional tracks to the project.
After you have completed editing
the 3D timeline then you can add additional audio tracks, such as “Over Dub”
and “Sound Track”. Additional tracks can be edited using normal Vegas
functions.
Although you can add additional
video tracks to your project, this is tricky because of the 3D timelines use of
“Compositing Mode” and “Parent Composite Mode”.
Although hand editing video event pan/crop settings in the 3D timeline is possible, it is very tricky and not recommended.
After editing the timeline you should use [File / Save As] to save your Vegas project.
Do not use the Make3D temporary “TmpMake3D.veg” project
name!
WARNING: The Vegas 3D Timeline Utilities do not handle multiple event
“Takes”.
The [Vegas / Help /
Contents and Index] “Vegas Pro Online Help” [Index
/ Time Selection] has the following
“Selecting a time range” instructions:
“Click and drag along the marker bar, CD layout bar, or a blank area of the timeline to select a time range. All events — and portions of events — within the region are highlighted.”
“Double-click an event and drag left or right to extend the selection to the next fade or event edge on that track.”
“Dragging within an event will change the event's position on the timeline. To create time selection without moving the event, hold [Ctrl+Shift] while dragging.”
“If the Allow edit cursor to be dragged check box is selected on the General tab of the Preferences dialog, dragging the edit cursor will change its position on the timeline. To create a time selection without moving the cursor, hold Shift while dragging”.
“Unless an event is locked, a selected time range affects all events—or portions of events—that occur within the range.”
“You can drag the ends of the time selection bar to adjust the selection length, or drag the middle of the bar to move the selection without changing its duration.”
The Vegas Online Help [Index / Editing Events / Cutting,
Copying, and Pasting Events] has the following
set of instructions:
“If you cut a time selection, events across all tracks are removed from
the timeline and placed on the clipboard. Events that extend beyond the time
selection are split at each end of the time selection:”
“If you copy a time selection, the portions of events that are within
the selection (across all tracks) are placed on the clipboard:”
“Position the cursor and click the Paste button (or press Ctrl+V). Events from the clipboard
are inserted at the cursor position.
Pasted events will sit on top of other events in the track if they overlap. To make space for pasted events, you can use Paste Insert or use post-edit ripple mode.”
Adding markers to the Vegas timeline is very important if you want to create BluRay compatible AVCHD DVDs. Because AVCHD DVDs do not have menus, adding markers to the timeline will allow chapter markers to be created during the AVCHD burn process. Chapter markers allow the [>>|] and [|<<] search buttons to work during playback.
Adding markers is also important if you want to render files for use by DVD Architect. The markers can be used by DVD Architect to create chapter markers.
The Vegas Online Help [Index / Markers / Inserting
Markers] has the following set of instructions:
“From the Insert menu, choose Marker to add a marker at the cursor position. Markers can be used to indicate points of interest in projects or to make notes in the project.”
1) Position the cursor where you want to add a marker.
2) From the Insert menu, choose Marker. A marker will be added at the cursor position and an edit box is displayed.
3) Type a name for the marker in the edit box and press Enter.
“If you choose to save markers in your rendered MPEG-2 file, DVD Architect will read those markers as chapter markers. Ensure the Render I-frames at markers check box is selected before rendering (in the Render As dialog, choose MainConcept MPEG-2 from the Template drop-down list, and then click the Custom button. In the Custom Template dialog, select the Video tab and select the Render I-frames at markers check box).”
Regardless of the Vegas Project Properties, the “Render 3D Timeline” tool can be used to create many output formats, including NTSC, PAL and IVTC Film.
The “Convert Timeline 3D Format” tool can convert the 3D timeline to Anaglyph Red/Cyan, Anaglyph Yellow/Blue, Anaglyph Green/Magenta, Side-By-Side, or Dual Stream 3D formats. The Dual Stream format can be used to create separate LEFT and RIGHT, or Field Sequential Interlaced output files.
Each of the possible “3D Output Types” can be rendered using different “Output Frame Rates” and “Video Output Formats”.
A Dual Stream 3D Timeline can be used to render separate LEFT and RIGHT, or Field Sequential Interlaced output files. The radio buttons in the “3D Output Type” group box will be enabled or disabled depending on the current 3D Timeline format.
The “Audio Tracks” group box selects which cameras audio track will be used when creating output files. Both the L Audio and R Audio 3D Timeline tracks should be in stereo and the audio output should be in stereo. Selecting either the left or right camera mutes the other camera’s audio track, and prevents unwanted echo effects in the audio output.
The “Output Frame Rate” and “Output Format” group boxes work together to select the Render Template used when creating output files.
Because Render Templates do not exist for all
combinations of “3D Output Type”,
“Output Frame Rate” and “Video Output Formats”, the “Render 3D Timeline” tool
radio buttons will be enabled or disabled depending on the availability of
appropriate Render Templates.
For example, “HDV 720x1280” and “HDV 1080x1440” do not exist for “IVTC Film”. Also, selecting “Field Sequential Interlaced” will disable the “IVTC Film” and BluRay buttons.
WARNING: The Render Timeline tool will not overwrite
existing files!
This is an intentionally
designed safety feature to help prevent the accidental destruction of output
files that may have taken many hours to render.
The Vegas Online Help [Index / Creating a DVD with DVD
Architect software] has the following comments:
“MPEG-2 video files rendered with the DVD NTSC or DVD PAL templates will not need to be recompressed. Audio will not need to be recompressed if rendered as stereo or surround AC-3 files with a bit rate of less than 448 kbps or as stereo, 48-kHz, 16-bit, WAV (PCM) files.”
1) If necessary, use the Convert 3D Timeline Format tool, and create desired output type.
2) Use the [Render Timeline] button to open the Render 3D Timeline tool.
3) Select [DVD Architect Widescreen] button in Output Format.
4) Select desired “Audio Tracks” option.
5) Select desired “Output Frame Rate” option.
6) Use the [Render Timeline] button to create the MPG and AC3 output files for DVD Architect.
Because of the way video resizing algorithms function, it is not possible to create high quality interlaced 3D video in a single recompression step. To minimize ghosting and other video compression artifacts it is necessary to first resize the left and right videos, and then in a second pass interlace the fields together.
The Render Timeline tool automates the two pass process by first creating resized intermediate left and right video files, next creating a 3D timeline using the resized files with appropriate interlace masks, and finally rendering the interlaced output.
1) If necessary, use the “Convert 3D Timeline Format” tool and use the [To Dual Stream] button.
2) Use the [Render Timeline] button to open the Render Timeline tool.
3) Select desired “3D Output Type” option.
4) Select desired “Output Frame Rate” option.
5) Select desired “Audio Tracks” option.
