And your iTunes could only recognize video files in MP4, MOV, M4V, etc. which means if you want to play Blu-ray on iTunes, you need firstly to rip Blu-ray to iTunes videos and then you can import Blu-ray to iTuens for freely and convenient HD Blu-ray playback. Meanwhile, the strict Blu-ray protection and region restrictions also make it necessary for you to convert Blu-ray to iTunes before you can watch Blu-ray on iTunes.

To rip Blu-ray to iTunes and then copy Blu-ray to iTunes library, you need to use a Blu-ray Converter for Windows 8 which easily helps you rip Blu-ray to iTunes video files and enable you to put Blu-ray on iTunes to freely watch Blu-ray on iTunes.

Flash movies load faster and save on download time because Flash is vector based whereas HTML is not. Flash gives the user (the person viewing/using the Flash movie) a more responsive ‘rich-client' like experience. All of these points are true, but they can be true for HTML pages as well (except for the vectors). I will address these points now: Flash pages can be made to load faster, but most of the time, the way they are designed in the real world, they do not. That is not a Flash problem, it is more an issue of the Flash developers going nuts with fancy and heavy Flash movies. What is Flash Tool? SWF Converter for Mac(SWF to MP4 Converting Mac and SWF to MOV Converting Mac) supports perfectly converting SWF to popular video, image and audio formats on Mac. After the conversion, you can effortlessly playback SWF movies with cool gadgets or share on Youtube etc on Mac. So when should you use Flash? In my humble opinion, I would use Flash to create a presentation that is similar to a television commercial. This type of presentation is something where the user sits back and enjoys the show as the Flash movie delivers the message to the client with animation, sound, and possibly video. Please do not get this confused with those ubiquitous ‘intro' animations that still plague many Flash sites. Rather I am talking about informative movies that the user can decide to view to learn about something like a product or a service. What I like about Flash development? 1. You can do some really nice work in Flash that would be difficult and sometimes impossible in HTML alone. Things like complex animations and playing video spring to mind. 2. Practically no browser issues: For the most part, Flash movies will work the same if the user is on Netscape or IE, on Mac or PC. The browser issues (where people coming to your site have different browsers that can ‘break' your pages) are quickly becoming a thing of the past since most people (thank the web gods) are using IE. But even today, I still have to deal with people who may be using some old browser that can break all but the simplest of HTML code. What DO I have against Flash? Before I start trashing Flash, I have to first say that I think it is a great tool, but not in all things and certainly not in the all-encompassing way that Macromedia would suggest. Here's why: Flash handles text very poorly. The web for the most part is about text, we go to the web to read about things, whether it be articles like this one, or what is in your shopping cart, or the latest baseball stats, it is all text. Flash text rendering/displaying is much slower than HTML and noticeably less clear. Macromedia knows this and that's why they include the ability to display basic HTML in Flash and that's why on their own site, they make heavy use of HTML. Flash development usually takes much longer than the HTML equivalent. This has been helped to a great degree starting with the release of FLASH MX where they essential provided HTML form components, but it is still slower to create a Flash site than an HTML site. With new technology like ASP.net and Java Server Faces, HTML now can react just like a ‘rich-client' application. Even without these new tools, properly designed HTML for most dynamic sites can provide a good user experience.

For newbies, it would be best to make use of these free software programs so that you will learn the basics of video editing. Once you get used to using different software programs, you can now purchase complex ones that offer special effects and other fun stuffs. Commercial software programs are too complicated for beginners so you’d be better off with free software.

Google and Adobe had finally announced that Flash .swf files could be crawled by Google! In fact, the extensive news release from the Adobe Developer Center also stated that Yahoo would be incorporating similar technology in short order. When I read this news and the consequential articles from the web marketing community it became very clear that this update was a great step but far from the fix that some Flash developers are likely to pitch to their clients.

Wikipedia:“Adobe Flash (previously called Shockwave Flash and Macromedia Flash) is a set of multimedia technologies developed and distributed by Adobe Systems and earlier by Macromedia. Since its introduction in 1996, Flash technology has become a popular method for adding animation and interactivity to web pages; Flash is commonly used to create animation, advertisements, and various web page components, to integrate video into web pages, and, more recently, to develop rich Internet applications.”

Search Engines Could Not Crawl Flash. Up until recently the textual content found in .swf Flash files was, for all intents and purposes, just as unreadable for search engine spiders as the text in images; only HTML text on a page could be read and indexed by search engine spiders because they could not yet (and still cannot) conduct on-the-fly optical character recognition.

Search Engines Can Crawl Text in Flash. For the first time, on June 30th, 2008 Google announced it could accurately spider the textual content hidden within Flash files found on the Internet. This major announcement was enabled by a partnership between Adobe, Google and Yahoo where Adobe provided their proprietary Flash Player technology to the search engines so they could integrate it into their systems and successfully ‘read’ the content within Flash files. This technology has vast implications for Google’s and soon Yahoo’s indexes because, at least in Google’s case, this allows the search engine to index the content within over 70.4 million Flash (SWF) files.

Search Engine Optimization Now Possible with Flash. The implementation of Flash crawling technology means that the text within Flash can now be indexed and links can be followed. Here are some examples of the basic optimization that is now possible within Flash:

1:Optimizing page content for specific keyphrase(s) to ensure a visiting search engine bot will correctly perceive the page’s topic.

2:Using keywords within internal links to pass link juice from page to page; only applicable for sites where the Flash pages are broken down onto separate URLs.

3:Providing emphasis (bolding) to particular words may help to emphasize keyphrase(s); but I am reaching here… it is unknown if this new technology provides text-importance recognition.

Single URL Flash Websites: Many websites I encounter still incorporate all of the website in a single Flash file; in other words as a user navigates the site they are still using the same URL but different pages appear. In such an instance the search engines will index the content and potentially drive traffic to the site but as Google cannot link to content within a Flash file all users will be sent to the beginning of the file. That type of indirect search result is likely to infuriate many searchers who have come to expect immediate results.

Text in Images is Not Indexed: Many Flash websites inexplicably incorporate a great deal of textual content within images and currently search engines cannot index text in images; I expect that will remain true for at least another year or two. As a result, a Flash website that includes a vast amount of text within graphics will not see a noticeable benefit to this enhanced crawling technology.

Resource-File Based Content Not Indexed: I noted this in Google’s comment area from their support team: “At this time, content loaded dynamically from resource files is not indexed. We’ve noted this feature request from several webmasters — look for this in a near future update.”

It is wonderful news that Flash is becoming more search engine friendly and there is no question that the addition of previously unattainable Flash content to search engine indexes will prove valuable.

Flash is an excellent technology for dealing with data visualization. It being client-side, it can reduce the amount of work your server has to perform in order to generate graphs and charts. Because of its robust ability in dealing with sleek and fluid animation and complex user interactivity, Flash is an excellent web and (and even desktop) application technology for dealing with graphing data.
