Jerky Animation

Can someone tell me why the image scroller here is a bit"jerky" as it goes across? I feel as if it could be smoother.

The smoothness of such effects is a result of the speed of the transition, the size of the increment being applied at each iteration, and the resolution of the images.

You can tweak and adjust the first two in the scripting.  A matter of experimentation to see what transition settings are at an acceptable speed and achieve the smoothness you want.  It you can't get it good enough that way, then you will need to more to lower resolution graphics that will re-render more quickly

I feel like this has more to do with browser rendering and how they render frame rates to be honest. As well as how pixels translate into that. I will try reducing my graphics a bit more but even with empty boxes, it's still not smooth, the jerkiness is in line with processing happening by the graphics card and browser. I think there are 2 many variables involved. The biggest being is that the animation is being rendered on the fly unlike flash which is pre-rendered then published.

You are only looking at it under on condition.  Anything that is using CPU, is going to be inconsistent.  CPU cycles are a shared resource.  It does not matter if it is flash, a java applet, javascript animation of even an animated gif.  the experience the user gets is dependent on there hardware capabilities, how current their software and OS is, and what else they have running.  

There are times when I have so many background processes running that everything just starts to hang and I have to start shutting down unnecessary processes.  The average user does not generally run into those kind of extremes, but the point is that you cannot guarantee the quality of animations for all users no matter what technology you use, because you cannot control the conditions under which the animation will be running.

Frankly, I don't see the little bit of unevenness as an issue.  It is a very ordinary, common presentation that looks like thousands of other front pages.  I doubt anyone not associated with the site is going to notice or care.

You show enough skills that you should try your hand at answering a few questions a month.  Answering a couple of questions a month would save you from having to pay the subscription and you would probably find that you benefit by learning from teaching.  

We can always use more Experts in the webdev topics.

I have actually done some answering maybe I should start doing that again. It would be fun. Don't they have a console you can download and get feeds?

For the older versions of the site there was, but it was not part of the site.  It was developed by an expert who is no longer around and it not longer works with the latest version of the site.  

You can set up filters to get email alerts  but I don't bother with any of that stuff.  When I have some time I just look in and see if there is anything I can help with.
