The Cheap-Ass Guide to RealAudio and RealVideo Files

(thanks to freespeech.org which is where we got this from)

Introduction to RealAudio and RealVideo

RealAudio and RealVideo, collectively known as RealMedia, is a technology that lets you watch video and listen to audio across the Internet. Two common audio file formats are .WAV and .AIFF. Currently, in order to listen to .WAV or .AIFF file that resides on a website you need to download it first to a folder and then open it with sound recorder (on a PC). To download a 10 minute clip of CD quality audio in these formats would take about 1 hour with a 28.8 kBit/Second modem!

RealMedia overcomes this problem by compressing the file hence making it smaller and by allowing the file to be "streamed" to your computer. By streaming a clip, the website (actually the RealMedia Server at the website) sends small packets of information (the audio and/or video file) over a connection you have to it. On the other end, you receive the information and play the media clip bit by bit. The process is almost invisible to you, except for a small amount of initial buffering. With streaming , you will see and hear the audio / video a short time after clicking on a link to it. The audio and video is streamed and played at the same time to a special audio and video player (called RealPlayer) thus eliminating the need to download the entire file first.

You simply download and install the free RealPlayer or pay for RealPlayer Plus from Real Networks. When you click on a link on a website that refers to a RealMedia file your browser will launch the RealPlayer and play the clip automatically.

It's all part of the RealNetworks RealMedia system. RealProducer creates the clips, RealServer sends the clips, and RealPlayer shows the clips. This guide will cover the following topics related to RealMedia files:

- How to watch or listen to them go
- How to create them (audio and video) go
- How to publish them on this web site go


How to watch or listen to realmedia

This is easy. You need at least a 28.8 modem and the latest version of RealPlayer RealPlayer from RealNetworks. There's a free version (which is certainly in keeping with our cheap-ass motif) and a pay version. If I told you not to bother with the pay version, RealNetworks would probably get mad at me and stop helping us promote our site. So I'm not gonna tell you that.


How to create realmedia

This is ever-so-slightly more complicated. The process for creating RealAudio and RealVideo files varies according to your resources and your needs. What follows are step-by-step instructions for a number of possible scenarios--all of which assume the lowest possible budget. For the definitive skinny on the subject, you should refer to (and bookmark) the RealSystem Production Guide.

Before you do anything else, you'll definitely need RealProducer. This is RealNetworks free creation and publishing tool and replaces the older RealEncoder. Go to tools for creating RealAudio and RealVideo page (scroll down to the "Download Today" link near the bottom of the page)

How to create just Audio:

Cheapest: Use a computer microphone (~$10) and the free RealProducer to create your own RealAudio "talk show." Instructions.

Less Cheap: Use a portable cassette player/recorder (~$20 - $50) and Cool Edit 96 ($0 - $50) to create your own "person in the street" interview show. Instructions.

How to create Audio and Video:

Cheapest: Use an inexpensive videoconferencing camera (~$120) and the free RealProducer to create your own deskbound "talking heads" television show. Instructions.

Less Cheap: Use a low-end camcorder (~$200), a low-end video capture board (~$100 - $200), video editing software ($0 - $200 - $600), and the free RealProducer to create a full-fledged "tv" series or documentary for the Internet. Instructions.


How to publish realmedia on this web site

We've tried to make this is easy as possible. First prepare your realmedia file, as explained above. Then, using the form on the publish web page, first fill out a few details about your story, such as a title, and your name. Skip over the text stories section, to the multimedia stories section. There you can press the Browse... button and locate the realmedia file on your hard drive that you want to publish.

Once that's done, you will need to select the correct media type using the mime type menu. Choose either audio/x-pn-realaudio or video/x-pn-realvideo, depending on whether your file is audio or video.

Finally, press the publish button. Please click your mouse button only once on the publish button (don't doubleclick), as otherwise the system will publish more than one copy of your story, and possibly one of them will be corrupted.

If you are publishing a long audio or video piece, it may take a while for it to be transferred. Unfortunately, there is no way we can get it to tell you how it's going, it just says "waiting..." until it is finished transferring. This might be a good time for a cup of tea, or a chat with a friend.

When it has finished, you'll see a new web page, telling you your new story has been published. Congratulations, your creative work is now online and linked from our news page.
