    Posted: 10 August 2011 at 5:48am
hi everyone!

A pixel of mine was accepted in the gallery, and it looked too fast.
I'm trying to emulate 12 fps, so in the photoshop animation panel, I gave each frame a delay of 0.08sec. This looks too fast on pixeljoint.

I remedied it by changing the frame delay to 0.1, and now it feels about right.

Is it a known issue? Is it my browser (firefox)? Is it my imagination? And if not, is there a remedy?

This is the animation in question:

Thanks

Somewhere on this section of the forum is a thread that explains this to great detail. I was unable to find it :(

Browsers do show speed at different rates. Hardware may affect speed too. I use PS and generally always hover on 0.02fps.

I kinda remember a 2009 journal entry on deviantart that listed the various  browsers's behaviors.
For example, Firefox respects duration >= 3/100s and converts smaller durations to 3/100s, except 0 which magically becomes 10/100s.
At least that's what it did in Firefox 3 -> 3.6, I haven't tested since.

Browsers follow these crazy rules in order to "fix" web images that have been created on broken image editors and visible on broken browsers in the 90s. Yay.

By the way, something that isn't even clear in the GIF 89a standard is whether the delay is in addition to rendering time, or if the rendering system should compensate rendering time (ie. result in a consistent total duration, no matter how fast the computer is, by skipping frames if necessary.)

@jal: 0.02fps = each frame lasts at least 50 seconds You mean 0.02s or 2/100s

thanks guys, I thought I was going crazy! Do you fix it when you post a pixel, or do you just leave it as is?

(50 seconds a frame, oh my gods, don't get me started! I was at an animation workshop two weeks ago, and one of the participants thought "claymation" is making a scene out of clay and then photographing it, and then making a movie out of it, by repeating three shots of the scene, zooming in and out and fading, accompanied by sappy 60ies french ballads. It was torture, and we all had to watch that twice. Arghh! If I can find it, I'll post it here, it was torture)

> Do you fix it when you post a pixel
Almost everybody will see animations only through a browser...

By the way, I don't really understand why 8/100s would visibly behave differently in Photoshop or on a browser. Maybe Photoshop itself would limit duration 10/100s when they're smaller ?

No, photoshop seems to respect the durations, because there's a real difference between .08s, 0.09s and .1s

At the risk of embarrassing myself again...
When I view my animations within Photoshop the timing is different than when I view in a browser. I always just preview in Firefox, Safari and Opera and judge from that.
It is my understanding that what you view within PS is correct and the browser speeds is just to find a 'happy visual medium' :/
