AVI to GIF: Convert Video from AVI(Audio Video Interleaved) to GIF(Animated GIF) with River Past Video Cleaner, AVI2GIF converter, conversion
Defined by Microsoft, AVI stands for Audio
Video Interleave. It is a special case of the RIFF
(Resource Interchange File Format). AVI is the most common format for audio/video
data on the PC.
AVI is Microsoft's response to Apple's QuickTime
technology. Early AVI files were limited on choice of video and audio codecs,
quality, and resolution. However, with the introduction of DirectShow, AVI became
a very flexible and powerful architecture. Some newer codecs including DivX
and XviD enable AVI files to have similar
or even better quality than DVD.
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.
Select output directory
Expand the "Output Directory" panel. Use the "Browse" button to select an output directory.
