Page 5: Using Flash Video Encoder
Using Flash Video Encoder Macromedia Flash 8 Video Encoder is a stand-alone video encoding application that lets you encode video in Macromedia Flash Video (FLV) format. The FLV format lets you easily incorporate video into a web page or Flash document in a format that almost anyone can view using the Flash Player. -
Page 6: About Flash Video And Flash Video Encoder
About Flash Video Exporter (QuickTime Export plug-in) If you have Macromedia Flash Professional 8 and QuickTime 6.1.1 or later installed on your computer, you can use the Macromedia Flash Video Exporter (QuickTime Export plug-in) to export FLV files from supported video-editing applications. You can then import these FLV files directly into Flash to use in your Flash documents. -
Page 7: Supported Video Compression Codecs For Flash Video
The following video-editing applications are supported by the QuickTime Export plug-in: Adobe After Effects (Windows and Macintosh) Apple FinalCut Pro (Macintosh) Apple QuickTime Pro (Windows and Macintosh) Avid Xpress DV (Windows and Macintosh) Avid Xpress DV does not support the encoding of an alpha channel when you use it to export to the FLV video format. -
Page 8: Comparing The On2 Vp6 And Sorenson Spark Video Codecs
It’s important to note that interframe codecs also use intraframes. Intraframes are used as the reference frames (keyframes) for the interframes. Both the On2 VP6 and Sorenson Spark codecs always begin with a keyframe. Each keyframe becomes the main reference frame for the following interframes. -
Page 9: Frame Rates
Because video looks much better at native frame rates (the frame rate at which the video was originally filmed), Macromedia recommends leaving the frame rate high if your delivery channels and playback platforms allow it. For full-motion NTSC, (the standard defined by the National Television System Committee in the U.S.), use 29.97 fps;... -
Page 10: Data Rates
Data rates The data rate affects the quality of a video clip and the audience that can download the file given their bandwidth constraints. When you deliver video using the Internet, you should produce files using lower data rates. Users with fast Internet connections can view the files with little or no delay, but dial-up users must wait for files to download. -
Page 11: Aspect Ratios (Frame Size)
An important dependency of the keyframe interval is that it affects the ability of Flash Player to seek (fast-forward or rewind) through an FLV file. Flash Player can only advance from keyframe to keyframe, so if you want to skip to different places and pause the frames, you must use a lower keyframe interval value. - Page 12 About encoding video with non-square pixels Most static computer graphics use square pixels, which have a width-to-height ratio of 1:1. When working with digital video, pixels often have a different width-to height ratio and are referred to as rectangular pixels. The reason for this behavior is to allow analog video (e.g. broadcast television) and digital video (e.g.

Page 13: About Encoding Audio-Only Files
To correct the image size when encoding using Flash Video Encoder, deselect the Maintain Aspect Ratio check box in the Advanced Encoding Settings dialog box, and enter the corrected dimensions at which to encode the video. For more information, see “Selecting advanced video encoding settings”... -
Page 14: Encoding Video With Flash Video Encoder
To encode video with the Flash Video Encoder: Start Flash Video Encoder by selecting Start > All Programs > Macromedia > Macromedia Flash 8 Video Encoder (Windows) or open the folder that contains the Macromedia Flash 8 Video Encoder application, and double click the application icon (Macintosh). - Page 15 Enter a filename for the encoded FLV file. If you don’t specify a filename, Flash Video Encoder uses the filename of the source video clip. When naming a file, do not enter the .flv extension; Flash Video Encoder does this automatically. You can specify a destination folder in which to save the encoded FLV file relative to the folder containing the source video clip.
-
Page 16: Saving The Encoding Queue
If you exit and restart Flash Video Encoder, or if you stop and restart the queue, a dialog box appears that lets you select the file to encode. The FLV encoded files are saved to the same folder as the source video files with a .flv file extension to identify them. -
Page 17: Stopping The Encoding Of The Current File
To reset a skipped file for encoding: Select the file or files in the encoding queue that you want to reset to the Waiting to Encode state. To select multiple files in the encoding queue, Control-click (Windows) or Command-click (Macintosh). Select Edit >... -
Page 18: Specifying Advanced Video Encoding Settings
Click Advanced Settings. The Advanced Flash Video Encoding Options are displayed. This dialog box lets you perform the following actions: Specify alternate encoding settings to deliver video for different bandwidths and applications. Create cue points to trigger events. Crop and trim the video clip to alter its dimensions as well as beginning and ending frames. - Page 19 To specify custom video encoding settings: Select the file or files whose encoding settings you want to modify. To select multiple files in the encoding list, Control-click (Windows) or Command-click (Macintosh), or select File > Select All to select all files in the encoding queue. Click Settings (Edit >...
- Page 20 Specify the quality setting for the video from the Quality pop-up menu. The quality setting determines the data rate of the encoded video. The higher the data rate, the better the quality of the encoded video clip. Select a preset Quality setting (Low, Medium, or High) to automatically select a Data Rate value.

Page 21: Specifying Advanced Audio Encoding Settings
Specifying advanced audio encoding settings The Encode Audio area of the Flash Video Encoding Settings dialog box is automatically enabled when an audio-only file is added to the encoding list (this portion of the dialog box is disabled when encoding video content with a combined audio track). You can select an encoding profile from the Flash Video Encoding Profile pop-up menu, which sets a corresponding profile for the audio-only encoding format To specify custom audio encoding settings:... - Page 22 Each cue point consists of a name and the time at which it occurs. You specify cue point times using the format: hour:minute:second:millisecond. In addition to embedding cue points within the encoded FLV video clip, you can create cue points using the FLVPlayback component. Using this component, you can create a cue point that is not embedded in the video clip itself, and allow you greater flexibility in triggering events.
- Page 23 Use the playback head to locate a specific point in the video where you want to embed a cue point. For greater precision, you can use the left and right arrow keys to move the playback head in millisecond increments. To do this, select the playback head, and then use the arrow keys to further adjust its position.

Page 24: Cropping And Trimming Video
To learn more about the differences between event and navigation cue points, see For more information, see Chapter 22, “FLVPlayback Component (Flash Professional Only),” of the Components Language Reference. Enter parameters for the selected cue point. Parameters are a set of key-value pairs that you can add to the cue point. The parameters are passed to the cue point event handler as members of the single parameter object. - Page 25 If you haven’t yet specified encoding setting for the video clip, do so now. To learn more, “Encoding video with Flash Video Encoder” on page Click the Crop and Trim tab. The Crop and Trim dialog box appears. Enter values for the right, left, top, and bottom edges to crop the video, or use the slider controls to visually adjust the dimensions of the video.
