Types of mp3 Players: a Quick Overview

MP3 players are pocket-sized electronic devices that have the ability to not only store, but play music and other sound files. Although MP3 players are sophisticated devices and there are of many types, they can be placed into one of three broad categories. These categories include hard drive based players, micro hard drive based players, and flash based players. Hard drive based MP3 players are typically larger and heavier than their competitors due to the fact that they contain a large capacity hard drive inside. This however, may be one of it’s only weaknesses. These MP3 players provide the largest capacity, ten gigabytes or more, out of the different types of MP3 players. Due to the fact that ten gigabytes equates to roughly 2,900 MP3 files, most consumers buy these players because they accommodate their entire MP3 collection. Micro hard drive based MP3 players are similar to their big brothers, the hard drive based players, except that they are a bit smaller, both in physical size and internal storage capacity. These MP3 players hold up to six gigabytes of MP3 files, which equals roughly 1,700 songs. Still boasting a respectable capacity, these players have won over many consumers due to their light-weight, compact size. Additionally, both hard drive and micro hard drive based players commonly contain rechargeable batteries that can not be replaced for a new battery, but only recharged. If it’s small size and moderate capacity that you are in search of this type of player may be just right. Flash based MP3 players are ultra compact, low capacity players contain no moving parts and consequently, never skip. Another advantage of these players is that their size and lack of moving parts allow them to use minimal power, causing your batteries to last longer. Also, these players almost always use replaceable, disposable batteries, allowing you to put in a new battery if your player should die in the middle of use. However, flash based MP3 players commonly range in capacity from 32 megabytes (roughly 10 songs) to two gigabytes (roughly 570 songs) at most. Therefore, most consumers with a large music collection tend to shy away from this type of MP3 player while athletes can appreciate the sturdy nature of these devices. Some of the different types of MP3 players include additional features as well. A few of the hard drive players include a small screen that can display pictures and video that are stored on the internal drive. Other players allow for digital voice recording for future playback.

5 Minute Guide to Video Editing for Beginners

Getting started with video editing is very simple you only need a few items and you can be producing quality movies at home that you will be able to enjoy for many years to come. Maybe even produce a hit Hollywood movie. The basic items you need are a video capture card, the software to edit, your computer, storage space on your computer and a camcorder, VCR, or you can display your movie on your computer screen. The process is effortless, all you do is capture the video to you computer using a capture card, then edit your video with video editing software and then download the video that you edited to either tape or burn it to a VCD, CD, or DVD. Let’s look at your computer first. You will need a minimum of a Pentium II 300 or faster, a minimum of 256 Megs of RAM, but you will get better performance with 512 Megs. You will also desire to have a 30GB drive that is split into 2 separate partitions. This means that you will have a C: and a D:. The C: should be given 10GB and will have all of your software stored there and the D: will be where your audio, video and editing projects are stored. Your graphics card should be a 32 Meg AGP. You can have an 8 or 16 Meg but the quality will not be as good. Storage is probably the most confusing thing about video editing. Video makers have many choices for storing their digital video files and this is why it can be so confusing. If you desire creating your own DVD’s then you are going to need lot of storage. The most you can get out of a single sided 4.7 GB DVD is around 2 hours of video. If you are using DV footage you are going to need 13GB per hour of video, this means you will need 26GB of storage and remember you always have extra footage that you need to factor that in as well so you are now up to 39GB of storage space needed. If you are adding other options such as graphics, MPEG2 footage for the DVD and the folder to hold it all then you are now up to 50GB. So, for your 2 hour movie you will need 50GB of space at least. So, when you begin be sure that you have enough storage on your computer for the type of video that you wish to store. On to the video capture card and the video editing software. When you first visit the electronics store you will find many manufacturers that create video capture cards. The most popular include Some of the reputable video capture card manufacturers are: Pinnacle, Matrox, Dazzle, ADS, Canopus, and Digital Origin. What video capture cards do to put it in simple terms is that these cards use hardware or software compression to digitize your video onto the hard drive on your computer. This way you can edit your video and play it back onto tape or display your movie on your computer screen. Some times, you can purchase the video capture cards along with the video editing software that you choose. Some of the most popular video capture cards that are packaged with video software include the Pinnacle Pro One which comes with the Adobe Premiere 6 full version, TitleDeko RT, DV Tools 2.0, Hollywood FX, and Impressions DVD. The Dazzle DV NOW AV can be purchased along with the Premiere 6 full version and the DVDit LE. Having music along with your video can also be accomplished with a MP3 Converter that will allow you to convert your MP3 music into a wav file or the format in which you need for your video. You may also wish to purchase a MP3 Encoder which will allow you to Wav or other formats into a MP3. A CD ripper is another item that you may wish to purchase that will help with converting your CD’s to MP3, WAV, WMA type files. One other software program that will make you life easier when you begin video editing is a MPEG Encoder which is a very easy to use program that will make converting several formats easy than you can imagine. Many of these MPEG converters will aid in converting DVD, VCD, AVI, MPEG, GIF, Flash, WMV, WMA, WAV, MP3, MP4, M4A, OGG, AAC, 3GP and even more/ So, now all you need to do is to find the best video editing software that you feel comfortable with and off you go. You can find several different video editing software companies that offer their software on a trial basis, this will let you try out the software so you can see if it is the perfect software for you. But, remember with the trial version you will be receiving the video capture card. You will have to purchase it separately. About the author:Natalie Aranda is a freelance writer.

Unlimited Bandwidth in Web Hosting

Bandwidth explained: Bandwidth is the amount of data transfer that you are allowed to have for a hosting package i.e. Let’s say you have a web page that is 48KB in size, now each time a user opens your site and goes to that page S/he downloads 48 KB of information on to their computer. If a 100 users view that page one time each then there has been a total of 4800 KB of data transferred from the server on which your files are stored for the computer of users. Size of web Page: 48 KB Number of users who viewed the web page: 100 Total amount of data transferred: 48KB * 100 = 4800 KB Bandwidth is the term that is used to denote the amount of data that has been transferred from your web space. The amount of bandwidth that you require while choosing a host depends on two factors: > The size of your site. > The popularity of your site. If your site is not very huge and you do not have any audio/video downloads and it’s not very popular i.e. not a lot of people visit your site then you do not really require a lot of bandwidth, on a average a web site uses up only 500 MB of bandwidth per month. Or if your site is small but extremely popular then you might have to go for a web hosting package that offers high bandwidth. On the other hand if your web site is huge, providing audio/video downloads, as well as being very popular then you would certainly require a huge amount of bandwidth. Let’s say you have a video file that is 150 MB in size and in a single day a 100 visitors download the file. This means that 15 GB of bandwidth will have been used. If you multiply that by 30 days for the month it comes to 450 GB. The unlimited bandwidth controversy For some time now a lot of hosting companies are supposedly providing "unlimited bandwidth" for their web hosting packages. It’s absolutely true, you can have unlimited bandwidth. However, you will need an unlimited amount of money by your side! Jokes apart, if you ever come across such a host it would be best to turn around and run back the way you came from. Just think, if you can get unlimited bandwidth for $25-30 a month then why aren’t big companies like Sun, Microsoft etc. not hosted there? In fact, why isn't everyone hosted there? For that matter, if unlimited is a standard feature then why don’t all the hosts offer it? Is it because it is expensive and requires better hardware? No, it’s because some hosts are honest and don’t give in to such gimmicks. Statistically speaking, a T1 Internet connection (huge broadband) equals approximately 500GB per month and costs around $1200 per month. So how can it be possible to get the same or unlimited for $30 a month? There are a lot of ways you can be duped by these ‘ unlimited’ hosts; here are just a few of them: The secret of ‘unlimited’ is actually buried in the Terms of Service by the host. Do not be surprised to find that unlimited = 15 GB. The host may restrict the sort of files that you can host on their server. Generally image galleries and audio/video files attract a lot more downloads thereby resulting in higher bandwidth consumption. So if there are no files of this type, your site won’t really require a lot of bandwidth. Some newly opened hosts use it as a scam. They take your money and after a few months when their server starts to become slow or reaches its limit, they run… with your money! Some hosts outline in their Terms of Service that you can have unlimited bandwidth as long as you qualify for it. i.e. Your site must use less then, let’s say 2 GB of bandwidth in order to qualify for the unlimited bandwidth feature. As soon as your site goes over that limit they either start charging you for it or cut off your downloads altogether. In life it’s a universal truth that you always get what you pay for, and it’s no different for web hosting. If a host is using a cheap advertising gimmick like ‘unlimited’ bandwidth they maybe lying about a few other things too. Their ‘dedicated’ support team could be a single person (the hoster itself in most cases) sitting in front of a computer and taking your calls. Do you really want unlimited bandwidth hosting from hosts that have very limited resources at their disposal? Or, do you want to go for a host that has spent thousands of dollars on setting up a good network infrastructure, servers, and a highly qualified and dedicated support team? The choice ultimately is yours and yours alone. About the author:Ashish Jain M6.Net Web Helpers

MPEG encoder for burning DVDs

MPEG, or Moving Picture Experts Group, is a jointly working group comprised of the International Standards Organization and International Electro-Technical Commission (ISO/IEC) to standardize the coding of moving pictures and the associated audio in a digital compressed format. MPEG-2 uses very sophisticated compression techniques to compress audio and video in order for it to be burned on a DVD. You can purchase and download hardware and software MPEG Encoders to burn a DVD. MPEG-2 is the process needed to encode video and audio information for a DVD burner, by burning the information onto a DVD disc with time stamps. The process of an MPEG encoder for burning DVDs is done using codec’s to encode the video and audio and save it in smaller pieces to be transformed into a frequency space and then quantized. MPEG-3 is one of the discontinued encoding processes for digital media, and is often confused for MPEG-1 (what we know as MP3). MP3 encoding has quickly become the standard for digitizing music around the world, and listening to it on your computer, laptop or personal MP3 Player. Most people burn mp3 songs to CDROMS, however for digital archiving, some people burn the files to DVD as well. To burn a DVD, you need a DVD burner, an MPEG Encoder, a blank DVD-R (recordable) disc and the audio and video that you wish to burn onto the DVD-R. MPEG Encoders can be bought as hardware or software and downloaded to transform and compress your audio and video file into MPEG format so that it can be burned onto a DVD using a DVD Burner. The process itself is quite complex and took a team of specialists to perfect. However, the process is streamlined where you as the end user are only expected to follow short, simple commands by the software to burn your encoded data. You can search the internet for a suitable MPEG encoder and also for a DVD burner that will best suit your needs. Your local computer shopping store will also have a variety of DVD burners with some expert advice on which products will best work for what information you are looking to encode and burn. And lastly, when in doubt about which MPEG compression algorithm to use to encode your data, “google” it. Chances are that you are not the only person who has had a question regarding MPEG encoding and DVD Burning. By doing your research early, you can ensure your next burn will go smoothly!

It’s Getting Harder To Watch Movies (CODEX)

After a long, exhausting day you came home, had your dinner and then sat in front of the TV looking for a nice relaxing movie. Nothing! Then suddenly you remembered that you bought the CD of the new, Oscar-winning movie “Million Dollar Baby”. You took out your laptop, inserted the first CD and hit “play”. To your surprise, the only thing you could see was a green screen. You took out the CD, cursing at the media market that gave you a “broken” CD for the fifth time. Tried the second CD; again the frustrating green screen. First thing in the morning, you took your “broken” movies and went to the shop. Having yelled at the owner of the shop for five minutes, you suddenly noticed the cynical smile on the guy’s face. Having the opportunity to talk, the shop keeper said “CODEX”. All you needed were the codecs for these movies. They were not broken; they were just coded in a “foreign” language to your media player. The codecs were the dictionary that your laptop had to use to translate the absurd computer language to the nice scenes of the movies. Every video, audio, picture or even word document files are coded in a different way. In the case of big data entries like movies, the computer has to use different algorithms to compress the data so that the size does not exceed the standard limits. We see this compression in PDF files (Acrobat Reader), in MP3 files (WinAMP), in MPEG files (movies), in each and every data storage file that you can imagine. While the compression is being done, the programs use some kind of a dictionary. Without these “dictionaries” (codecs in the case of video and audio files) the code would seem as meaningless to the player or the viewer as it is to you. So you have to install certain codecs to be able to use certain files. Some codecs replace the repetitive symbols over the file, ome codecs changes the aspect ratio of the movie; some of them decrease the quality of the picture and yet, all of them turn gigabytes of data into fair size that can fit into a CD or a DVD. As the user demands increases, codecs are multiplying in a logarithmic scale. There are several codecs that are musts for movie fans, however. You should install most of these if you don’t want to be disappointed. 1. MPEG4 - It is the default codec which is already included in WMP. 2. DIVX - A series of sound and display codex which come with shareware DIVX player. 3. XVID - Relatively new, one of the most used video codecs. 4. AC3 - Most common sound codec. 5. Intel Indeo - Rather useful series of codec which a new version pops out everyday. Overall the way movies are encoded is changing day by day. Everyday we see a new aspect ratio. Everyday we encounter a new codec. To many, it would seem that it is getting harder and hard to watch movies. The least you can do is to download a codec viewer program which would help you on your quest for a pleasant evening.

How To Compare Digital Camera Prices

Digital camera prices have been constantly dropping whilst the quality and complexity of the digital cameras has been rising rapidly. People who used to only dream of owning a digital camera because of the excessive digital camera prices may now be able to afford much better cameras than they realize. In fact, digital camera prices have changed so dramatically that a 5- or 6-megapixel point-and-shoot digital camera has dropped below what a 4-megapixel camera was selling for less than a year ago. Digital camera prices of $200-$300 are now common for good point-and-shoot digital cameras that come with an image resolution of up to 5 mega pixels and a 3X optical zoom lens. It is important to recognize what the minimum features are to expect for this range of digital camera prices. Digital camera prices between $200 and $300 should include: * 1.3 frames per second shooting capability * 10 to 20 scene modes * built-in flash * lens openings from f2.8 to f4.8 * optical viewfinder and an LCD of 1.5 to 2 inches * optical zoom lens with a range equivalent to that of a 35-115mm lens * rechargeable batteries * shutter speeds of 4 seconds to 1/2000 second * solid plastic or metal housing * video clip capture at 320 by 240 resolution with audio Digital camera prices can vary and it is essential to know what the most useful features are. Obviously you want to take good pictures but don’t want to pay the inflated digital camera prices that the high-end cameras have. However, your priority should be to assess which features are the most important to enable you to take the best pictures. The higher the numbers of megapixels that the cameras have, the higher the digital camera prices are but this does not necessarily guarantee better pictures. One of the most useful features to look for in the $200-$300 range of digital camera prices for point-and-shoot picture taking is scene modes. Digital camera prices are not affected very much by having scene modes but these allow an amateur photographer to take shots such as a fireworks display and sunsets without knowing how to adjust the camera settings manually. The majority of the better digital cameras within the $200-$300 range of digital camera prices have scene mode selections available. Another feature of cameras within the $200-$300 range of digital camera prices is that they are compact and will fit in a jacket pocket.
