AVI to GIF: Convert Video from AVI(Audio Video Interleaved) to GIF(Animated GIF) with River Past Video Cleaner, AVI2GIF converter, conversion


What is AVI?

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.


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.


Additional Requirements

AVI is a file container format. It may use standard Windows codecs, or any of the third party codecs. If it uses a third party audio codec, you need to have the codec installed on your system for River Past Audio Converter to decode the file.

If you get an error when adding an AVI file, please open it in Windows Media Player and see if you can play it with audio. If not, you must find out what audio compression is used in the file and download the codec.

If you cannot add the AVI file, it may contain video and audio which use codecs not installed on your system. You can verify that by playing the AVI in Windows Media Player.

If WMP cannot play the file, the codecs absent. You will need to find out which codecs are used to encode the AVI and install them.

Usually, you can install ffdShow, which is compatible with many video compression, including DivX and Xvid. For audio, you may need to install AC-3 Decoder Filter or CoreAAC.

You can change the size, and frame rate of the video.

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.



Convert
