ASF to MKV: Convert Video from ASF(Advanced Streaming Format) to MKV(Matroska Video) with River Past Video Cleaner, ASF2MKV converter, conversion
What is
ASF?
Advanced Systems Format (formerly Advanced Streaming Format,
Active Streaming Format) is Microsoft's proprietary digital audio/digital video container format, especially
meant for streaming
media. ASF is part of the Windows Media framework.
The format does not specify how (i.e. with which codec) the video or audio should be encoded; it just
specifies the structure of the video/audio stream. This is similar to the
function performed by the QuickTime, AVI, or Ogg container
formats. One of the objectives of ASF was to support playback from digital media servers, HTTP servers, and local storage
devices such as hard
disk drives.
What is
MKV?
Matroska aims to become THE standard
of multimedia container formats. It was derived from a project called MCF, but
differentiates from it significantly because it is based on EBML (Extensible
Binary Meta Language), a binary derivative of XML. EBML enables the Matroska
Development Team to gain significant advantages in terms of future format extensibility,
without breaking file support in old parsers.
It is intended to serve as a universal format for storing common multimedia
content, like movies or TV shows. Matroska is similar in conception to other
containers like AVI, MP4 or ASF, but is completely open source. Matroska file
types are .MKV for video (and audio) and .MKA for audio-only files.
To encode MKV video, please have CCCP
installed.

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 "MKV - Matroska Video" as the "File Type".
Troubleshoot
If you don't see the MKV output option, you have a problem with your Matroska Pack installation.
We need Matroska Pack 1.1.2 or later to encode MKV video. Matroska 1.1.2 is included in CCCP. Please download and install CCCP.
Download CCCP
Note: To convert to MKV files, you must have Matroska Pack installed.
Change Video Settings
Click on the toggle to the left of the "Video 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.
Change Audio Settings
Click on the toggle to the left of the "Audio Settings" label to expand the panel.
Select the audio compressor for the conversion. Depending on the compressor, you may also change the sample rate, channel (stereo or mono), bits/sample, and bitrate.
Do not use "MPEG Layer-3" as the audio compressor. It does not work correctly in video files and often causes the conversion to abort in the middle. If you prefer to have MP3 audio in the AVI file, download lame_enc.dll instead.
Select output directory
Expand the "Output Directory" panel. Use the "Browse" button to select an output directory.
Convert
Click the "Convert" button on the tool bar.
