FLV to MKV: Convert Video from FLV(Flash Video) to MKV(Matroska Video) with River Past Video Cleaner, FLV2MKV converter, conversion

What is FLV?

FLV is the video format used by Flash.

FLV (Flash Video) is a proprietary file format used to deliver video over the Internet using Adobe Flash Player (formerly known as Macromedia Flash Player) version 6, 7, 8, or 9. FLV content may also be embedded within SWF files. Notable users of the FLV format include YouTube, Google Video, Reuters.com Yahoo! Video and MySpace.

To convert FLV video to other formats with River Past software, you need to have CCCP installed.

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.

Troubleshoot

If you don't see the MKV output option, you have a problem with your Matroska Pack installation.

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.
