View Full Version : Frames per second?

16 Nov 2010, 3:57 PM
Maybe I'm missing something, but is there an option to set the frames per second in the animation?

No, because amount of fps depends on performance of browser and hardware that you use to view your animation. Thats why you see only time units on timeline. In Flash theres a need for 'fps' setting, because of specific keyframe/frame system and age of this technology. 8-6 years ago it was impossible to play rich content with speed above 20 fps. Whole system was getting slow and unresponsive. So it was better if animator optimized his animation to play at 12-15 fps, so it wont get jerky on less powerful machines. Fps in Flash are like manual way of controlling how much data cpu have to work with in a second.

On a side note, Apple artificially limit maximal number of fps on it's devices to 60 fps, to save battery live and reduce processor load. It would make no sense to play iTunes cover flow or banner animation with 200 fps, if maximum that human can perceive is 60 fps.

Hope it helped.

That's not really the issue we are facing. As a TV animation studio, we have an entire library of flash animation that we were hoping to easily port to the iPad. By exporting PNG sequences, we hoped Sencha would be the perfect fit, but without being able to control the fps, it's not going to work.

So ask devs in Features Request for option (script?) for loading multiple images to timeline and automatically setting appropriate time for each (1/24th of second, right?).

Making image sequences of hundreds of png's isn't perfect way for content conversion...But thats just me thinking loud ;)

I would imagine that Adobe is going to come out with a product to ease the conversion of Flash animation to HTML5. Being a Flash user myself, I'm happy to see that Sencha has come out with a product that competes directly with Flash in this market.

The existence of Sencha will not only force Adobe's product to be better as a result of the competition. Sencha has a unique opportunity to sway developers like myself away from the platform, towards the HTML5 paradigm sooner than Adobe might be prepared for.

I like what I see coming from Sencha so far, but I'm not sure it makes sense to create tools specifically for converting FLA or SWF based content. That being said, whatever you can do to ease the transition for us would be very welcome.

Simulating FPS would be helpful. Playing looped movie content (animated sprites), sound triggering, and an Event Model tied into your JavaScript framework would all be great to see.
