If you want to put video on your website, you must have a good knowledge of the basic video file types. Today we will try to have the most popular video file formats explained, their pros, their cons, as well as when and where they can be best used. With video implementation on your webpages.
There are three basic video file types on the internet. Most UNIX workstations, for instance, cannot view QuickTime movies. I believe the QuickTime file type is the most popular, since a lot of huge entertainment and news sites use it exclusively on their web pages.
AVI is the oldest of the three main file types. It is a windows oriented video format, but it’s not the most popular because of the sound and video compatibility and synchronizing problems. Because the QuickTime, format can be used on either a "windows" or a Macintosh, computer, the AVI video file type loses its popularity every day.
The hardware and software you need to digitize video into the QuickTime format is very inexpensive, compared to the MPEG format. MPEG is used on video games, CD-ROM and other media that require high output quality. One disadvantage of MPEG is that it sacrifices file size to gain in digital quality. Most DVDs exhibit few visible MPEG compression artifacts on a properly configured system.
Another disadvantage of the MPEG format is that you really need time and sophisticated hardware and software to convert plain video into MPEG. And let’s not forget that the MPEG format is not supported by apple and Macintosh, meaning that if you put MPEG video on your website, those users with Macintosh, will not be able to see it.
QuickTime, is by far the most popular video file type developed by apple for Macintosh, users, but is also compatible with the IBM-compatible machines and the windows operating systems. The hardware and software you need to digitize video into the QuickTime, format is very inexpensive, compared to the MPEG format. So it's much easier and cheaper to create video and put it on your website using the QuickTime, format.
You can take the next shuttle to the moon or planet Mars on NASA’s dime. Would you jump for joy and suit-up, or would you cringe at the very thought of leaving this planet’s atmosphere? I’m on the fence with this one. The roller coaster hesitates for a split second at the peak of its steep track after a long, slow climb. You know what's about to happen — and there's no way to avoid it now. It's time to hang onto the handrail, palms sweating, heart racing, and brace yourself for the wild ride down. It’s difficult to not associate death with outer space. After all, we’ve seen what can happen to those billion dollar space shuttles. I think for a lot of us, it’s best to stick with a planetarium, current space video or DVD. The cosmos has been expanding since the Big Bang, but how fast? The answer could reveal whether everything we thought we knew about physics is wrong.
Millions of us watched as a civilian, a school teacher, climbed into a shuttle headed for outer space. This was back in the 1980s, so I was in elementary school at the time. My teacher happily flipped on the television so that our entire class could view in amazement. Unfortunately, our amazement was not related to viewing a successful take-off. Some aspect of the space shuttle was faulty and all went wrong. Lives were ended and hopes were shattered. It was undoubting a dismal day for NASA. However, there have also been plenty of successful journeys into outer space as well. You can catch the highlights on a contemporary space video or DVD at home. Teach your children what the folks at NASA have accomplished over the years.
Clearly, there is more to becoming involved with NASA than watching a space video or two and feeling passionate about astronomy. If you’re really into the stars and moons, I suggest you pursue a college degree in Astronomy or physics. Today, the Doctor of Philosophy still requires a love of wisdom but applies to individuals who have pursued knowledge in a much more specialized. This way you can become a professor, who teaches the wonders of astronomy, or possibly even acquire a position at NASA. That would be amazing! Imagine you and your family are astronauts on the space station right now. You can only use the resources available to you. How would you adapt to the challenges and still keep doing important routines, like exercising, learning and making time for fun?. Who can vie with that?
