**2.4.4 Multimedia video formats**

The AVI (Audio Video Interleave) format was developed by Microsoft. The AVI format is supported by all computers running Windows, and by all the most popular web browsers. It is a very common format on the Internet, but not always possible to play on non-Windows computers. Videos stored in the AVI format have the extension .avi.

Microsoft develops the Windows Media format. Windows Media is a common format on the Internet, but Windows Media movies cannot be played on non-Windows computer without an extra (free) component installed. Some later Windows Media movies cannot play at all on non-Windows computers because no player is available. Videos stored in the Windows Media format have the extension .wmv.

On-demand streaming is based on files stored on a server for a longer period. Files are available to customers as they submit their requests to the server. Live streaming videos are transmissions that occur as the performances or events depicted take place. Streaming technology has caused a profound change in education, business, media and entertainment, as it combines the richness of television content with the interactivity of

Video tutorials are not a new concept. The concept has emerged in the late 1960s, when Bandura, first commented on the issue of self-modelling. Since then, video modelling has been described as "instructional videos" or "video tutorials". Most video tutorials are produced as part of a strategy to promote guidance in developing new skills and abilities for example, to improve teacher training or to prepare medical students for their internship experience. Also, video tutorials have been used to assess their effectiveness in improving

Video tutorials are one of the most important factors in the improvement of the educational process. As we also mentioned in the conclusions of this work, the video tutorial has a strong impact on students. It can exist in two modes. The first one is as a separate entity with no text. In this case several independent tutorials treat a particular topic. The second mode is having it embedded in a website, or as part of a topic that is presented in the context of web page or slideshow. In both cases the video tutorial is recorded using

By offering audio-visual demonstrations, the teacher can use a video tutorial to develop a particular skill or strategy. Thus, video tutorials can be used as a medium to encourage students to learn independently outside the regular classroom schedule. The materials presented in the audio explanations and the visual demonstrations become achievable goals that the learner can reach by understanding and applying a similar process to produce their own project. The video tutorial resources may used to engage learners to explore their technical skills. Exposure to software operation in the target language might empower students to become familiar with the target technical lexical items thus enabling them to discuss their difficulties with their teacher or peer. Hence, the teachers' role becomes one of facilitator or guide when a student needs further assistance, and their oral interaction has the potential to change from language learning to purposeful communication exchange

Camtasia is one of the applications that can be used to make a video tutorial. TechSmith produces it. Video tutorials created with Camtasia assists in creating demonstration videos by recording computer screen activities. For example, one could video record the screen as they type. Even though Camtasia is fairly user friendly, some video editing skills are

The MPEG (Moving Pictures Expert Group) format is the most popular format on the Internet. It is cross-platform, and supported by all the most popular web browsers. Videos stored in the MPEG format have the extension .mpg or .mpeg.

Apple develops the QuickTime format. QuickTime is a common format on the Internet, but QuickTime movies cannot be played on a Windows computer without an extra (free) component installed. Videos stored in the QuickTime format have the extension .mov.

To achieve multimedia tutorials one can use both Internet and INTRANET technologies based on what was mentioned above. This depends the type of software used. For image processing, one can use software like: Photoshop, Corel Draw, or open source products, like GIMP. To achieve animation we can use the FLASH product or software that captures the screen image like Camtasia. We will write some words about Camtasia in the "Video Tutorials" section of this paper.
