ImageMagick cannot find its shared library, libMagick.so

I compiled imagemagick/perlmagick and installed it however when I try to import perlmagick I get the following error $ perl -e "use Image::Magick" Can't load '/website/lib/perl5/vendor_perl/5.14.2/x86_64-linux-thread-multi/auto/Image/Magick/Magick.so' for module Image::Magick: libMagickCor...

Re: Is there anyway to dissolve between the last/first frame

So would you recommend I create 2 animated gifs, one with the morphing sequence and the other of the non-morphing sequence. Then combine the two animated gifs?

As far as I could tell from looking at the documentation, there is no way to set the morphing sequence for a subset of an image series

This command takes 6 frames a second over 5 seconds $ ffmpeg -i video.mp4 r 6 -t 5 frames/ffout%03d.gif Would I be able to dissolve the last and first frames given this set ...

Re: Is there anyway to dissolve between the last/first frame

Thanks for the prompt reply but there may be a misunderstanding. The animated gif I included has loops, and I know how to do that already. Do you notice how there is a dissolve transition at the end of the loop? Is there a way I can produce that effect through image magick? I specifically looking fo...

Is there anyway to dissolve between the last/first frames?

Is there a way to dissolve between the last few frames and the first few frames of a series of stills to create the effect of a seamless loop? I have a series of about 30 images I generated with ffmpeg. The below syntax captures 6 images every 5 seconds. $ ffmpeg -i video.mp4 -ss 62 -r 6 -t 5 frames...

Re: How to lower file size of gifs from youtube videos?

I understand it's not limited to powers of two as you mentioned previously.

Thanks for the follow up clarification.

Re: How to lower file size of gifs from youtube videos?

I see. I tried 256, 128, 62, 32, 16 as arguments to -colors. I think I'll stick with my original approach and possible -remap to my own pallette later. Thanks for your help :D

Re: How to lower file size of gifs from youtube videos?

convert your images from ffmpeg to png. then convert the pngs to GIF using the -colors or -recolor option if you want an animated gif. Sorry for my ignorance, but isn't this exactly what I did before? ffmpeg -i video.mp4 -r 6 -t 5 frames/ffout%03d.png convert -delay 10 -loop 0 -colors 256 frames/ff...

Re: How to lower file size of gifs from youtube videos?

What is wrong with just using JPG and compressing as desired? I tried the following (saving to jpg), but the results weren't satisfactory. The size was way high. $ ffmpeg -i video.mp4 -r 6 -t 5 frames/ffout%03d.jpg $ convert -delay 10 -loop 0 frames/ffout*.jpg output.gif Do you know how I could ach...
