I do like this app for creating gifs from videos. When you work with this app, you’d see every single frame on the tray at the bottom of your picGIF screen. you can easily delete any you chose and you can add at liberty. It does have a few shortcomings in my estimation, but bear in mind, that any of those shortcomings is easily addressed by any number of online GIF-editing programs, (where you, however, won’t find the quality of picGIF at the same time). For example, picGIF only offers certain predetermined sizes for the GIFs you want to create. Once you create a GIF with picGIf, just go to one of those on-line GIFF applications and crop the white borders that are left when you make a GIF with picGIF. Along the same lines, while picGIF does give the dimensions available for the creation of the GIF you want to create, it doesn’t give the actual size of the resulting file which you will see will be formatted with (probably) unwanted borders, so you have to create the gif first and use your Finder (in mac) or Windows to see how large the file is that you’ve created. But, these are easy shortfalls to get around. Over all, it’s a fine choice.
