If you like GIFs, Instagiffer lets you create your own animations directly from YouTube videos, without having to download them first. You can also make them from videos that you have saved on your hard drive, or even using a screencast.
With Instagiffer you can let your imagination run wild and create GIFs from any video. The animations are easy to create; you just have to specify the start time and length of the GIF.
You can choose how long the GIF is in minutes, seconds, and even tenths of seconds, so you can be sure to get only the exact part of the video you want. Instagiffer also includes other features that let you change the quality and the look of the animation, and get a perfect GIF as a result.
With this application you can also change the number of frames per second, the size of the frame, add effects, add text to the GIF, and change the speed of the animation.
