Using the app is very easy. Just select the file and the part of the video you want to use. For example, if you load in a one or two minute video, you can edit it down to a funny five second gif.
Once you've selected the part of the video or the gif you want, you'll find the quality options for exporting: frames per second and resolution. You'll also be able to speed up the video or make it repeat (if it's a gif).
Video and GIF Memes also allows you to add text to the export file. Just select where you want the text to appear, type it in, select a font and font color, and you're done.
Video and GIF Memes is a gif creation app that's very interesting. Although it doesn't have a ton of options, it does have a simple, intuitive interface. The results are great too.
Requires Android 4.0.3 or higher
