#GIFSICLE SPEED UP GIF SOFTWARE#

However, the strange thing is that I NEVER see the flicker when I display the GIFs using other software - e.g. I suspect that the flicker is more noticeable on an older PC with a slower CPU running Win XP than on my newest PC which has a faster CPU and is running Win 10. I also 'think' that this may be dependent on the processing speed of the PC.

In some cases this does seem to have worked, but not in all. It occurred to me that I could use these to change the delay time of the last image - in the GIFs that flicker - to a larger value, to allow more time to go 'back' to the first image. In some cases, the image I download is moving much too fast, and I have used online GIF editors (ezgif and ) to change the delay times to a more appropriate value. I have established to my own satisfaction that this flicker appears only when the image is repeating automatically - as if the action of returning to the first image is taking just a little too long and the black image (or part image) interferes. Most of these display perfectly well, but a small number display an annoying flicker - a sort of momentary black band (covering some - or sometimes it may even be all - of the image) that lasts a very short time. I like to use irfanview to display animated GIFs that I have downloaded (and some that I have constructed myself).
