MP4/M4V to RM: Convert Video from MP4/M4V(MPEG-4 Video) to RM(RealMedia) with River Past Video Cleaner, MP4/M4V2RM converter, conversion

What is MP4/M4V?

A video compression standard planned for late 1998. MPEG-4 extends the earlier MPEG-1 and MPEG-2 algorithms with synthesis of speech and video, fractal compression, computer visualisation and artificial intelligence-based image processing techniques.

MPEG.ORG is an excellent source for additional information on MPEG format and usage.

There are several ways to decode MP4 video. Most of the time, having Apple QuickTime installed is sufficient. Occasionally, a file is not compatible with QuickTime. You will need to install CCCP when that happens.

What is RM?

A streaming technology developed by RealNetworks for transmitting live video over the Internet. RealVideo uses a variety of data compression techniques and works with both normal IP connections as well as IP Multicast connections.

More information is available on RealNetwork web site.

To convert other video formats to RealMedia, you will need River Past RealMedia Booster Pack in addition to your video software.

Select output format

Use the setting panel on the bottom of the window to control the output format. Click on the toggle to the left of the "Output Format" label to expand the panel. Select "RM - RealMedia" as the "File Type".

Note: To convert to RealMedia, you must have River Past RealMedia Booster Pack installed.

Change Audience

The audience specifies the target audience for your video streaming. It is normally bitrate based for streaming, or quality based if you just want to store the video for local playback. For example, to enable users of 512k DSL to play the video from internet, select "512k DSL or Cable" as the audience.

Change Video Settings

Click on the toggle to the left of the "RealVideo Settings" label to expand the panel.

Select "Specify" under "Size" and/or "Frame rate" to enter the video resolution and/or frame rate.

You can change the compressor, quality, size, and frame rate of the video.

RealVideo uses temporal compression. This means, only key frames contains complete information about the video frame. All other frames contains the difference from previous frame or frames. A "Key Frame" of 15 means there will be one key frame every 15 frames. Larger key frame setting will reduce the file size, but reduce the quality of all the none-key frames.

Change the "Mode" and "Complexity" settings according to your content so the RealVideo encoder can optimize its algorithm accordingly.

Change Audio Settings

Click on the toggle to the left of the "RealAudio Settings" label to expand the panel.

Select the audio compressor for the conversion. You may also change the sample rate, channel (stereo or mono), and bits/sample. You can also leave the setting to "Automatic" so the software choose the best settings depending on the original material.
