Chapter 3: Advanced Features
In addition to editing files, RealMedia Editor gives you advanced features that can help you with the editing process. You can view information about all streams that are incorporated into a RealMedia file. Plus, you can decide how fast RealMedia Editor will preview a clip: quickly or normal speed.
Viewing Stream Information
Every RealMedia file is created with a number of streams. Single rate files contain only one stream, while SureStream files can contain multiple streams depending on the number of target audiences a clip is encoded for.
RealMedia Editor allows you to easily view valuable information about each stream that associated with a RealMedia file.
To view stream information:
- Open a RealMedia file.
- Select Stream Info from the Tools menu.
The Stream Info dialog opens, giving you the following information about the file:
- Audio Format-the type of audio for the encoded clip (such as music, voice, or stereo)
- Video Quality-the quality of the encoded video (such as normal or smooth motion)
- Video Size-the size and width, in pixels, of the encoded video
- File Type-either single rate or SureStream
This dialog also gives you the following information about each stream within the file:
- Bit Rate-the amount of bandwidth necessary to view the stream
- Preroll-the amount of bits needed to download before the stream can play
- Frequency-the frequency response of the encoded audio for the stream
- Codec-the compression/decompression coded used to encode the stream.
- Click Close to return to the main window.
Changing RealMedia Editor Preferences
RealMedia Editor allows you to change how you preview a clip when it is opened in the main window. You can set RealMedia Editor to view a clip quickly, or you can set RealMedia Editor to view a clip more accurately. If you choose to view a clip accurately, it may take much more time to open if the clip is large in size.
To change RealMedia Editor preferences:
- Select Preferences from the Tools menu.
The Preferences dialog opens.
- Select either Accurate or Quick to designate how you want RealMedia Editor to open new RealMedia files.
- Quick-plays back the selection immediately with out delay, but audio and video may not play exactly as they would in the saved clip. For example, frames of video at the beginning of a clip may appear different. And audio may not stop precisely at the end of a clip.
- Accurate-saves the selection to a temporary file and can take longer for long selections. The preview, however, will look and sound exactly like the saved clip.
- Click OK to return to the main window.
