MKV to GIF: Convert Video from MKV(Matroska Video) to GIF(Animated GIF) with River Past Video Cleaner, MKV2GIF converter, conversion

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 convert MKV files to other video formats, please have CCCP installed.

What is GIF?

Animated GIF is not really a video format. It is a sequence of GIF frames stringed together. Due to the 256-color limitation of GIF, the color is dithered. The compression is not that great, so the file size tend to be large given the frame rate and resolution.

However, since GIF is supported by all web browsers without any add-on, it is a great way to create small video thumbnails. Generally, the resolution should be kept small (80x60, for example), the frame rate should be kept low (4 fps, for example), and the duration should be kept under a few seconds.

Animated GIF is not really a video format. It uses 256-color GIF compression, with low quality and relatively large files. It is not suitable for video playback. However, since it is supported by all web browsers without any add-on's, it is a great format for video thumbnails and should be used for this purpose only.

To encode a video to an animated GIF, you need to have River Past Animated GIF Booster Pack in addition to the video software.

Animated GIF is NOT a video format and is not designed for video playback. It is limited to 256 colors, so the video will be dithered. GIF compression is designed for solid color graphics, so it is not very efficient for video. The resulted animated GIF files are normally much larger than the original video file, given the same resolution and frame rate.

For the above reasons, it is not a good idea to use animated GIF to share your video on the web. Instead, it is an excellent way to display a small moving thumbnail for the link to your video. For this purpose, you should specify the size to around 80 x 60, and frame rate to 2 frames per second for the best result.
