It is an image file, not video. GIF file format support more pictures in one file to create and view it as short animation, but this not a video.
an image file
A GIF file (graphics interchange format) is a simple, low quality image file or animation. Most raster image programs can open and edit GIF images, but GIF animations acn only be edited by programs specifically capable of doing so. GIF files can be viewed by many different programs, usually any program that can display an image file will allow you to see a GIF.
Are you talking about 'gif' not 'giff'? if you are than a gif is an industry standard raster graphic or image format. To make it simpler incase you didn't understand, it is an image that is animated, or could be a picture put into a gif form.
A GIF image can hold up to 256 different colors per image.
.gif is an image file, suitable for charts and simple graphcs that do not require a large colour palette.
The extension is actually immaterial. It merely serves to give the operating system a hint as to the file's content, allowing the file to be associated with a particular application, such as a GIF file viewer or an image editor application. In order to save a GIF file, you must first re-encode the image (assuming it is not already in GIF format), and save the output to a file with a GIF extension.
.gif is a file format. Most commonly .gif files are animations or images with a short 5-10 second effect. Non-animation image file formats are: .Jpeg and .PNG.
You have to create or have some kind of "preview image" to display. Once you decide what your preview image is going to be, you upload the gif file as you would any other file, but you will be asked to provide a preview image to go with you gif. Upload your preview image, (if you don't have a preview image you can't complete the submission of a gif file.)then complete the rest of your submission.Without a preview image you cant complete the submission of a gif file. Same goes for submitting brushes for photoshop and gimp as well as any zip files. They need an accompanying preview image in order to submit these types of files on "deviantART".
