?????Appending Other Clips to Your Clip??
Helix Producer also allows you to combine one RealMedia file to another, thus "appending" a file to the current file. ???Appending only works when the number and type of streams in each file is identical.?? Therefore, this feature works best when the source files are all encoded with the Helix Producer using the exact same settings.
Because of RealMedia Editor's 2 GB limit for the size of files it can open, the combination of appended files can not be over this limit.

???????衾To append a file:  ??
1??Open a RealMedia file.
2??Select Append RealMedia File from the File menu.
    The Open RealMedia File dialog opens.
3??Locate the file you want to append, then select it and click Open.
   RealMedia Editor appends the file to the currently open file. This process can take some time, depending on how large the appended file is.
4??When the appending process is complete, you can edit the combined files as a new clip; the original clip is closed

?????????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: ??
1??Open a RealMedia file.
2??Select Stream Info from the Tools menu.
The Stream Info dialog opens, giving you the following information about the file:
     Audio Mode??the type of audio for the encoded clip (such as music or voice)
     Video Mode??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.
3??Click Close to return to the main window.
