CHP. 13USING ADVANCED VIDEO FEATURES 227 Capturing a timeline snapshot You can create still images of a single frame of your project. Once saved, the snapshot can be used just like any other still image. 1.Position the cursor on the frame of the project you wish to capture as a still image. 2.Click the Save Snapshot to File button () on the Video Preview window. The Image Filename dialog appears. 3.Select a file format (JPEG or PNG) and enter a name for the new still image file. 4.Click Save. The image is added to the Project Media window. Creating a slide show A slide show composed of still images and an accompanying soundtrack can be an excellent way to show off your pictures. You can insert multiple images to instantly create a slide show, complete with crossfades. Importing high-resolution still images and using panning, cropping, and track motion tools can add interest to an otherwise static slide show. For more information, see Cropping video on page 223 and Adding track motion on page 281. 1.In the Options menu, verify that Automatic Crossfades is selected. 2.From the Options menu, choose Preferences. Adjust the following settings on the Editing tab: Enter the length for the still images in the New still image length box. Select Automatically overlap multiple selected media when added. Enter the length of the automatic overlap in the Amount box in the Cut-to-overlap conversion section of the dialog. 3.Click OK. The Preferences dialog closes. 4.Select all of the images you want to use in the Explorer. 5.Right-click and drag these files to the timeline. 6.From the shortcut menu, choose Add Across Time.

228 USING ADVANCED VIDEO FEATURESCHP. 13 If you want, you can replace the crossfades between images by dragging transitions to the crossfade regions at a later time. For more information, see Using transition effects on page 268. Note: When using photographs or other media that is not the same frame aspect as your video, youll see black bars on the sides or above and below the image. To create a crop rectangle that matches the project frame aspect, right-click the image and choose Match Output Aspect from the shortcut menu. Creating titles Most video projects include titles and credits. There are two ways to add text to your project. You can use the titling engine (text generator) or you can use an external image-editing program to create titles. For more information, see Using generated media on page 247. Creating titles from images While every software application is slightly different, the general procedure for creating titles with a transparent background is as follows. 1.Start your image-editing application. 2.From the File menu, choose New. Set the dimensions of the new image to be the same as the frame size for the project. For more information, see Correcting images for DV pixel aspect ratios on page 226. Make the default canvas (background) color a solid color. The background will be transparent in the final image, so any solid color works. 3.Select the Text tool and enter the text for your title. Note: Size and position your titles carefully to fit within the Title Safe Area or the titles may extend beyond the edges of your television. For more information, see Identifying safe areas on page 293. 4.From the File menu, choose Save As. 5.From the Save as type drop-down list, choose TGA, PNG, PSD or BMP (PNG is recommended). Make sure that you save the alpha channel information (for TGA and PNG), which is used for transparency. 6.Enter a name and click Save. 7.Insert the image in a track just above the one with the video that will be in the background.

CHP. 13USING ADVANCED VIDEO FEATURES 229 8.Click the Compositing Mode button () on the title track and choose Source Alpha if your image has an alpha channel associated with it. If it does not, you may need to add a chroma key filter to the image and key out the background. For more information, see Chroma keying on page 264. Note: The alpha channel is saved as a selection area in some programs. If you cannot save the alpha channel, use a black background and a mask will be created from the background. The alpha channel of TGA images may not be detected automatically. For more information, see Modifying media file properties on page 239. Fading titles Another common technique is to fade a still title in and out. You can create this effect by using an opacity envelope on a title event. For more information, see Using opacity envelopes on page 177. You can also create multiple title images and then use crossfades or custom transitions between them. For more information, see Using transition effects on page 268. Adding closed captioning to Windows Media Video (WMV) files Closed captioning makes your final video accessible to a wider audience. You can use text commands to add captions line-by-line to a Windows Media ® Video (WMV) file, or for longer projects, you can add captioning from a script.

230 USING ADVANCED VIDEO FEATURESCHP. 13 Adding closed captioning line-by-line 1.Position the cursor where you want the closed captioning text to appear. 2.From the Insert menu, choose Command. The Command Properties dialog appears. 3.From the Command drop-down list, choose Te x t. 4.In the Parameter box, enter the closed captioning text you want to display. 5.Click OK. 6.Repeat steps 1-5 for each line of closed captioning text you want to add. 7.Render your file in Windows Media Video format. For more information, see Rendering a project on page 307. Tip: Take steps to ensure that the closed captioning displays when the video is played. For more information, see Displaying closed captioning on page 232. Adding closed captioning from a script This feature is available only in the full version of Vegas software. Using a script to generate closed captioning involves several steps. First, you must copy and paste the lines from the script into a spreadsheet. You can create the spreadsheet from scratch (using the steps that follow) or use the sample shell (Vegas Captioning Shell.txt) provided in the Sample Projects folder on the Vegas software CD. You can open this tab-delimited shell with a spreadsheet application or, in the absence of a spreadsheet application, any text editor. Once the spreadsheet is complete, you can copy and paste the lines into the Edit Details window. You can set the position for each line of closed captioning during playback. Creating a script spreadsheet 1.Create a four-column, tab-delimited spreadsheet. 2.In the first column, enter 00:00:00:00 in each of the cells as a placeholder. You will set the actual position of each line during playback. 3.In the second column, enter TEXT in each of the cells to specify the command type. 4.In the third column, enter the text that you want to display as a closed caption. Enter each line in its own cell. Tip: If you have a script, you can copy and paste individual lines into the cells. 5.In the fourth column, enter a label to identify your captions. An entry such as Line 001 can help you sort the captions once you paste them into your Vegas project.

CHP. 13USING ADVANCED VIDEO FEATURES 231 Note: The final caption displays in the Microsoft® Windows Media ® Player until the end of the video. To clear the final caption sooner, add a final command with no text (as shown above). Copying and pasting captions into Vegas software 1.Select the cells in the spreadsheet and copy them. 2.Switch to Vegas software and choose Edit Details from the View menu. The Edit Details window appears. 3.From the Show drop-down list, choose Commands. 4.Right-click the gray box in the upper-left corner and choose Paste from the shortcut menu. The spreadsheet data is pasted into the Edit Details window. 5.Click the column header for the Comments column. This sorts the captions by line number. Setting closed captioning timing 1.Position the cursor shortly before where you want the first caption to occur. 2.Select the row for the first caption in the Edit Details window. 3.Click the Play button () to start playback. 4.When playback reaches the place where the first caption should occur, press . The first caption is inserted at the cursor position, updates the Po si t io n setting in the Edit Details window, and selects the next caption. 5.Press to insert each subsequent caption. 6.Render your file in Windows Media Video format. For more information, see Rendering a project on page 307. Click the Comments column header to sort the captions by line number.Right-click to paste the spreadsheet contents into the Edit Details window. Ctrl+K Ctrl +K

232 USING ADVANCED VIDEO FEATURESCHP. 13 Displaying closed captioning You may use one of two methods for displaying the closed captioning when the video is played: Instruct your audience to turn on captioning: In Windows Media Player 7 and 8: from the View menu, choose Now Playing Tools, and then choose Captions from the submenu. In Windows Media Player 9: from the Play menu, choose Captions and Subtitles, and then choose On if Available from the submenu. Create an HTML page with the Windows Media Player embedded in it. See the online help for a sample HTML page. Resampling video Resampling allows Vegas software to interpolate frames in an event when the frame rate of a media file is lower than the project’s frame rate. With resampling, the intervening frames are interpolated from the source frames, much like a crossfade between the original frames. You can instruct Vegas software to resample the video of a single video event or to resample the entire project at the time of final rendering: To resample an event, right-click a video event and choose Properties from the shortcut menu. In the Video Event tab of the Properties dialog, choose the Smart resample, Force resample, or Disable resample radio button. For more information, see Accessing event properties on page 174. To resample the project, choose Render As from the File menu. In the Render As dialog, click the Custom button to access custom rendering settings. Select the Resample the frame rate of all video check box. For more information, see Customizing the rendering process on page 311. Without resampling, the intervening frames are simply the previous frame repeated. With resampling, the intervening frames are interpolated from the source frames. The original media file looks To convert these three frames into nine frames for a faster frame rate, Vegas software must generate something like this over three frames. It is similar to a crossfade effect between the original frames. the intervening frames.

CHP. 13USING ADVANCED VIDEO FEATURES 233 Resampling at either the event or project level perform the same function. There are few cases where resampling may be particularly important: When the frame rate of the source media for an event is slower than the project’s frame rate. For example, when you are using a source media file that has a 10 fps rate in a 29.97 fps rate project, resampling is recommended. When changing the speed of a video event. For example, when slowing a clip to 30% using a velocity envelope, resampling is recommended. When creating vertically scrolling titles. When any of the above situations are true, there are only ten frames of source material for every second of project time. When the project is rendered, there must be roughly thirty frames in each second. The frames must be created between the source media frames, sometimes known as padding. The easiest way to do this is to simply duplicate the previous frame. This can result in less than smooth video playback. Resampling allows Vegas software to interpolate the intervening frames more smoothly. Using Edit Decision Lists (EDL) This feature is available only in the full version of Vegas software. Vegas Edit Decision Lists (EDL) are text lists of all of the media files used, where they are placed, and how they are trimmed. Vegas EDLs are not the same as those used in traditional linear editing suites and are not intended as a project interchange for other editing applications. Creating an EDL 1.From the File menu, choose Save As. The Save As dialog appears. 2.From the Save as type list choose EDL Text File (.txt). 3.Enter a name for the file and browse for a destination. 4.Click Save. You can open EDLs created in another application in order to work with a rough copy of a project. For example, you could create an EDL from a project in a third-party editing application and then import the project into Vegas software via the EDL. For best results, save the EDL file and source media files in a single folder before opening the EDL. Opening an EDL 1.From the File menu, choose Open. 2.Locate the EDL file, select it, and click the Open button. If you are working on another project, you are prompted to save your work before a new project is opened. Note: EDLs do not contain any information about the location of source media. Therefore, the EDL file should be saved in the same directory as the source media. If it is not, or if media is stored in a number of different locations, you are prompted to relink these files when the EDL is imported. Because of the significant differences between editing applications, third-party EDL files may not bring all of the project data into Vegas software. Among other differences, events are inserted into the timeline on a single track, all transition effects are replaced with crossfades, and only four audio tracks can be imported.

234 USING ADVANCED VIDEO FEATURESCHP. 13 Working in DV format Vegas software is optimized for DV editing. If your project is destined for tape or television, the DV format is an excellent choice. The Sony Media Software DV codec provides video with excellent image quality, even over multiple generations, and provides audio that is better than CD-quality. If you start with well-shot DV footage and stay within the DV format throughout the editing process, you can output broadcast-quality video programs. This section provides guidelines for working in the DV format. Selecting source media Wherever possible, use DV source video clips. You can capture video from DV cameras and decks using an IEEE-1394 card with no quality loss. You can also convert analog footage to DV using a media converter or by passing the video through a DV camcorder. Setting project properties Set your project to match the DV format of your final output. This provides a true WYSIWYG view of the project when you use an external monitor for previewing. This also prevents you from stretching output or changing field order unnecessarily. You can match the project settings to a video source file by using the Match Media Settings button () in the Project Properties dialog. For more information, see Setting video properties based on a media file on page 44 and Modifying project video properties on page 238. Selecting templates Always select a DV template when performing any of the following tasks in a DV project: prerendering video (pg. 289) rendering to a new track (pg. 153) printing video to tape from the timeline (pg. 323) rendering a project (pg. 307) When prerendering video or rendering to a new track, a DV template not only optimizes playback performance, but also helps you avoid needless recompression of DV footage. DV material is recompressed only when necessary. Cuts-only DV sequences are not recompressed when you output the project to DV from the timeline or in Video Capture. The DV templates are designed to provide high quality, pixel aspect-correct, DV-compliant renders when rendering a project or printing to tape from the timeline. Do not select an uncompressed setting when choosing rendering or print-to-tape options. An uncompressed setting produces a large file that will not print back to DV tape from Video Capture or from the timeline.

CHP. 13USING ADVANCED VIDEO FEATURES 235 Eliminating out-of-range colors The DV format allows color values to exceed broadcast NTSC and PAL color level standards. If you have a scene whose colors are too hot, or if you want to be sure that your video stays within legal broadcast levels, apply the Broadcast Colors effect to specific events or the entire project. Be aware that applying the Broadcast Colors effect results in recompression of the video. As a result, render times can increase significantly when the effect is applied to the entire project.

236 USING ADVANCED VIDEO FEATURESCHP. 13 Working in HDV format This feature is available only in the full version of Vegas software and in Vegas Movie Studio Platinum software. HDV cameras record high-definition video to standard DV tapes using a highly compressed variation of the MPEG-2 format. Because of this compression, you can capture HDV clips at data rates that are no higher than DV capture. However, editing and previewing this highly compressed video is impractical without a very powerful computer that is optimized for working with high-definition video. We recommend converting your HDV files to an intermediate format for editing. Depending on your final delivery format, working with HDV source material requires some adjustments to your workflow. This section will help guide you through the decisions to streamline the process. Choosing a capture format If you will be delivering your project in standard definition (SD) via DVD or DV tape, you can use the camera’s built-in down-conversion (if available) to convert your HDV video to the DV format. Use the camera’s Options menu to set the camera to output DV, and you can capture and edit video in the same way that you normally use DV in Vegas projects with no need for intermediate files. If you will be delivering your project in a high-definition (HD) format, in both SD and HD formats, or as SD 24p video, capture HDV clips and convert them to an intermediate format after capturing. Creating intermediate files If you’ve captured HDV clips, converting to an intermediate, lower-resolution format will streamline the editing process and allow you to preview your project. 1.Start a new project. 2.Add your captured HDV clips (MPEG-2 transport streams) to the timeline. 3.Render your clips to an appropriate intermediate format. You can verify a template’s codec by looking at the Video format drop-down list on the Video tab of the Custom Template dialog. If you’re performing frame rate or frame size conversion, ensure the Video rendering quality is set to Best on the Project tab of the Custom Template dialog.
