Ah, now that would work. I didn't consider a middle mogrify, and that solution is so unintuitive I'd never have stumbled upon it.

Problem thoroughly solved. Thanks again.

South means the bottom pixel of the animation stays at the bottom - but halfway through, his knee becomes lower than his feet, so his right foot starts floating. Without any gravity, his helmet stays constant and his feet float. I don't think it can be done without the original trim offsets ...

fmw42 your solution has the same problem as snibgo's - ground level doesn't stay constant. In the end I hacked up some Java that took in the source frames, trimmed and aligned them, and wrote them out as png24 frames for imagemagick to convert to a gif or mng. I was going to quantize and build the ...

Excellent! Thank you for this! However, just to be awkward... I have a whole stack of animations to make. Is there any way to avoid that -extent 249x492 and instead something like -extent (size of union of all frames in this animation) . If not, I'll just have to hardcode that in. (Edited to add ...

The blue background shrinks against a background that is white on my viewers. That's the problem... I want the background to be the same blue. Strangely, I can get this working if I choose red as the background, but when I change that to khaki (for testing) or this cadet grey, it fails again. I am ...

Ah well. Thanks for taking the time to have a go!

Sorry, I didn't check to see if there would be any restrictions. I have checked this, and it should be fine : http://wikisend.com/download/686428/frames.zip

The first 24 frames. Thanks for your help on this.

Not for me...



Can I upload attachments here? A small zip of a few source frames might be helpful...

Any black is being put there by convert - my source frames have a blue background. http://i.imgur.com/LgZBweF.png Adding fuzz convert r:\in.*.png -set delay 1x24 -coalesce -fuzz 50% -trim -set dispose background -colors 256 +dither -layers TrimBounds -background khaki -layers optimize r:\out.gif ...

perhaps you need to trim twice (with -fuzz XX%), once for the white and once for the black. and do a -layers optimize Wait, no. First, the white is an artifact of the screengrab, I'm not worried about that. I followed your advice, and it works if I use '-background blue' or '-background red'. Any ...

YES!

I SHALL NAME MY FIRSTBORN fmw42!

I have a sequence of .pngs, which comprise a blue background with an actor somewhere in the middle. I want to make this into a compact .gif, showing just the actor. I'm using this command line : convert r:\in.*.png -set delay 1x24 -coalesce -trim -set dispose background -layers TrimBounds r:\out.gif ...
