It was ages ago but I used to use Camtasia to create gifs from videos, and I think it let you edit the speed. Not sure how that would work with an already-gif. You might have to screen capture the gif as a video, and then edit it and and produce it as a new gif, which I know sounds nuts, but unless you created the gif in something like fireworks and still have the original file with all the layers (old school gif-making style yo!)….. I also use several iPhone apps that might could do the trick but you’d lose image quality and possibly gain a watermark. -val > On Nov 13, 2021, at 1:02 PM, charles meyer <[log in to unmask]> wrote: > > Hi my esteemed listmates, > > I understand GIF is considered by many an antiquated and/or non preferred > format. > > But, I can't open a GIF created by a trusted source with W10 Windows Media > Player. > > I can open it in Irfanview but is there a way in Irfaview to slow the GIF > down? > > If not, has anyone used any free, downloadable GIF viewers which enable you > to slow a GIF down? > > Thank you. > > Charles.
