These days there is a heated debate in web development circles on comparisons of HTML5 and Flash. Some people are dooming Flash for its slowness and in particular the aversion it gets from the SEO community with regards to text displays and loading of web pages. When comparing both of these web development tools/ applications, it is important to look at their strengths and weaknesses and in particular the areas of their application.

Difference

Basically Flash provided extended features to the legacy versions of HTML. The real reason for the popularity of HTML5 is its ability to show video content. It shows the lively video content through Actionscript and CSS3 by using tags.

Video Comparisons

Two major operating systems in common use are Windows and Mac. On Mac operating system with Safari as a browser, HTML5 uses much lesser CPU resources as compared to Flash but HTML5 videos don’t run in Windows’ environment.

For a Mac OS comparison of videos using both the technologies in Google Chrome haven’t much in it. On Windows, Flash clearly outperforms HTML5 in Google Chrome’s browser. With a Firefox browser running on Mac OS HTML5 performs better but situation is even on Windows.

HTML5 video cannot be used on a 3D plane. HTML5 doesn’t support dynamic content on the videos such as titles and captions. Moreover HTML5 video can’t handle alpha channels and you can’t enlarge it to full view in web pages.

Application Areas

Flash is sparingly used in website design. However its basic purpose was to serve applications for multimedia and gaming, especially those belonging to corporate sector. Flash also provides opportunities in mobile platforms. HTML5 is likely the majority of the web designing industry’s favorite along with CSS3. The current stats, however, don’t recognize this fact because the browsers are still not compatible with HTML5.

Platforms

HTML5 can’t create apps on desktop while Flash doesn’t work on iPad. In fact the debate of comparison was catalyzed with Apple making iPad incompatible with Flash. Although this argument of creating desktop apps is not from a web developer’s point of view but this is what Flash can do.

Web Conferencing

HTML5 can’t record from your web cam so you can’t share those FLV files with anyone. Currently it also doesn’t support audio recording with microphone. HTML5 can’t do web video conferencing, which is an important part of every day business.

Security

HTML5 has an upper hand with regards to security issues. It is an open source standard and is integrated directly into web browsers rather than a Plug-in. Flash has had many security bugs in the past. However developers should implement HTML5 carefully because it is a new standard distinct from its predecessors; whilst offering many powerful features.

HTML5 is seen to have definite advantage in web designing and development sphere but Flash can’t be ignored owing to the fact that it has other application areas.
