Flash Video

The sine qua non conditions for a video posted on a website can be seen in high definition, are as follows: it is necessary that the video file has been created at a resolution of frame of 1920 1080 pixels, it is also necessary for the Viewer to have a monitor capable of reproducing a resolution of 1920 1080 pixels, in additionthe viewer must have a team capable of processing the data volume from a video file in high definition, no loss of frames, and also recommended bitrates of between 7 and 10 Mbps for the encoding of videos in high definition, hardly achievable figures with the current basic Internet connections. If one of these four premises fails, we cannot say that we are seeing high definition video, although a high quality video, which is a more generic term. and what they are, and what role play the video codecs? In Europe, every second of a movie, contains 25 frames, and if we speak of standard definition, each frame, every second of a movie, contains more than 400,000 pixels. Four numbers making we realize that, without compression, few would be the computers capable of processing video files. Codecs (codec) define standards or specifications about how you should proceed to compress digital data, depending on the format or target of each production support. All digital video created for its dissemination has been encoded using a particular codec of compression. Depending on the scope of dissemination of an audiovisual, its producer will use a video codec or another. For web videos are generally encoded in Flash Video format (with extension Flv) or H.264 format.

Current versions of Flash use the On2VP6 codec to compress video, and H.264 format is based on the Mpeg-4 standard. In short, how we adjust the balance between quality and compression to achieve the perfect balance? That is the question of the million. It is very difficult to determine, by way of prescription, the commandments that must meet all video for web, that will guarantee the highest possible quality, since every project has some particular technical requirements. To summarize I commented that: in Atractium work since the beginning of the chain of production (in the shooting), to the highest resolution possible (HDV formats). Thus, we are always in time reduce frame sizes, where deemed appropriate. We also considered the potential viewer of the video of each of our clients, who is what is expected to be Internet access and its transmission speeds, and of course, what the capacity and speed of the server that will host every video.

Flash Actionscript

The good thing: interactivity Flash Actionscript opens up a vast field of possibilities. Programmers and designers have been used to create interactive Flash features ranging from very lively feedback forms in Flash games-based attractions. This new level of interactivity always leaves visitors wanting to go back for more. A standardized site with Flash, you don’t have to worry about cross-browser compatibility. No more problems about how to display a certain CSS code in a different way in Internet Explorer, Firefox and Opera. When the position of the elements of your site in Flash, always appear as they are, provided that the user has Flash Player installed.

Better expression through animation in Flash, can make use of features of animation to convey a message in a much more efficient and effective manner. Flash is a lightweight option for animation, since this vector-based (and therefore, the file sizes are smaller), against actual files of film that are much bigger in size. The bad and the ugly: people Flash Player must download the Flash player in advance before you can view Flash movies, so that through the use of Flash range of visitors decrease significantly, since not everyone will be willing to download the Flash Player just to view your site. You will also need to put additional work to redirect the user to the page download Flash player if he or she does not have the player installed. The optimization of the web if your content was presented in Flash, most search engines will not be able to index your content. Therefore, you will not be able to rank well in the search engines and there will be less traffic that is directed to your site.

The charging time users have to wait longer than usual to load Flash content compared to normal text and images, and some visitors may lose patience and you click the back button. How much largest is your Flash more it takes to charge, and more risk of losing visitors. The best way to make or use flash is only if is absolutely necessary the interactivity and motion that comes with it. Otherwise, it is recommended the use of a mixture of Flash and HTML or use of pure text, if your site is only the present simple textual and graphical information.
