    FF v IE animated gif comparison (1.5 and 6)

    I have just put together a little animation using PovRay and Fireworks. I was testing it out in both IE 6 and Firefox 1.5 and note (IMHO) that there is a distinct difference...is it just me or can somebody else see a difference? <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15>

    I am surprised because I thought FF would be running the animation faster than IE but on my two browsers (FF on the MAC and IE on the PC) they actually seem to be the same speed. I can't detect a difference! <img src=/S/nope.gif border=0 alt=nope width=15 height=15>

    Hi Skitterbug

    I was testing it locally and I saw a distinct shudder and slowness in IE and a lovely smooth spin in Firefox. That is interesting, let me see if there are any PC's with Firefox out there to compare for me.

    The frame speed is set to 7/100th Second so should be a reasonable animation frame change...thanks.

    I see it fastest in IE, then slower in FF, then slightly slower again in Opera, but there's not a great deal of difference, not as much as in the dancing bananas we discussed some time ago.

    <P ID="edit" class=small>(Edited by skitterbug on 22-May-06 17:27. Just another note about it)</P>Hi Jerry,

    I opened FF 1.5 now on that same PC along with IE 6 and I still don't see a difference here. <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15>

    Added: I forgot that I have Safari 2.0.3 (on the MAC) and it seems to be the same speed as FF and IE .....my <img src=/S/2cents.gif border=0 alt=2cents width=15 height=15>

    I arranged IE6 and FF 1.5.0.2 side by side and let the two images merge by crossing my eyes. There was no difference whatsoever in speed - animation was smooth in both windows, with a very slight hickup at one point, probably where the animation starts over.

    There is a noticeable difference in FF -- slower and jerkier, showing a slight pause, once per apparent revolution.

    Thanks to all for checking , this is great to know. I was on my rather flaky PC at home when I originally posted this thread and it was just an apparent nuisance...been testing it on my super duper laptop here at work and it looks OK

    FWIW, I can see a sporadic judder on both IE and FF at home and at work. I can't quite pin it down as it doesn't seem totally consistent, but if anything is once every 'revolution'.

    (I also note I can see a judder when I view it with my Coffee Cup gif animator software, so it may not be a browser issue...)

    The lack of concensus is interesting. Looks fine in both browsers to me, although was slightly jerky on loading in IE.
    It's a very <img src=/S/clever.gif border=0 alt=clever width=15 height=15> image, by the way - well done!

    If at first you do succeed, you&#39;ve probably missed something.

    Got blocked out of the Lounge earlier then meetings..but....

    The sporadic judder is caused by the end of the loop for the frames.

    It was created using PovRay which created approximately 30 or so individual bitmaps. The way it works is to change the camera angle on the bucky ball and take a "snapshot". I imported each image into Fireworks, frame by frame and then washed it through. I think that if I do it again I will have to ensure that I revolve around using the equation.

    360 + 360/N degrees

    where N is the number of frames and change the first and last frames to be half the other times.

    Oh yes - now I remember. They were <img src=/S/mice.gif border=0 alt=mice width=50 height=25> not <img src=/S/bananas.gif border=0 alt=bananas width=33 height=35> <img src=/S/bananas.gif border=0 alt=bananas width=33 height=35> !
