ASF to GIF: Convert Video from ASF(Advanced Streaming Format) to GIF(Animated GIF) with River Past Video Cleaner, ASF2GIF 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 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.
