Unintended change in AdWords Flash to HTML5 conversion my company wants to run some advertisements on Google AdWords. We made some animated Flash ads, however AdWords automatically converts the ads from Flash to HTML5 with some unintended changes. See below the difference between the two. It seems that when moving an image it's a lower quality than when it's finished moving.

Flash:



HTML5: (pay attention to when the images stop moving)



Anyone have an idea how to prevent that from happening? Made the individual vector images in Illustrator and imported them in Flash to make the animation. Only used a simple motion tween to move the image inside the screen.
I would recommend to export as HTML5 from Flash directly instead of relying on Googles conversion.
This has to do with how the Google conversion is animating this. It's probably based on an HTML5 canvas which can have Anti Aliasing disabled in certain events to improve performance.
Google maybe also enforce this to have a pleasant web performance for users. Flash has generally very poor performance because of things like that.

You might want to ask this on Stackoverflow instead, this is more a web programming question.
