As digital video involves far more data such as moving visuals and sound as opposed to a simple word processing document or even a photograph, it inevitably takes up far more room on your hard drive. Even if you intend storing video files on an external drive, you’ll still need to work with them on your hard drive initially and this is why video compression is so important as it involves making files smaller so that they can be stored more practically.

Doesn’t Compression Mean Losing Quality?
With digital video, the aspects of the compression don’t end up affecting the quality that we can perceive. A couple of examples are where there are literally billions of colors but variations in shades are so subtle that to us with the naked eye, we cannot comprehend the tiniest changes in shade and therefore not all of that data is needed, hence it can be compressed.

Likewise, although an object may be present in a scene for a minute or even longer, an example being a static table in a room, it’s not necessary to keep all the data contained in each particular frame as the table is going nowhere. So, in effect, compression is really a function of getting rid of all the saved data that has been captured during filming which, to the capabilities of our eyesight as viewers, we don’t really need as we wouldn’t be able to perceive any difference even if it wasn’t compressed.

Options
It is also necessary to determine which compression format tool works best for your specific project. The likes of DivX has become increasingly popular for compressing full length feature films whilst other film makers use MPEG-4 which has translated very well into the use of compression for the likes of viewing shorter clips on hand held PCs, personal music players which are now capable of showing visual clips and even longer feature length movies. Some of the video clips you can get on mobile phones will also have been compressed using MPEG-4 whilst other applications still use MPEG1 and MPEG2.

Some file formats use up more bit-rates per second with the resulting quality exactly the same so there is no real tried and trusted answer to the solution of video compression for your own specific project and upon what media platform you intend to view it. Ultimately, it’s a case of trying out different compression formats and seeing what works best for your particular project, reading up on the subject and speaking to others working in the industry for their advice based upon your specific projects and needs.

The Best Way Of Maximising Compression
Standard digital camcorders tend to compress data at a ratio of 5 to 1, although there are many formats which enable data to be compressed at a far higher ratio. The key is to use as much compression as possible and then stop when you spot with your own eyes that the quality is starting to diminish and then, simply to push the compression back a bit until quality is restored.

And, it really is a case of there not being a standard fixed rate of compression which you should be aiming for. Some videos look fantastic when tightly compressed yet the same amount of compression on others looks awful.

You’ve probably got an video footage of a party or traveling, where you’ll come across a scene and wish you could have simply captured a particular second on the tape which would have made for a perfect photo. There are numerous ways you can do this but the quickest and most simple is to use a software application called BlazeDVD?Freeware? which you can download for free from http://www.blazevideo.com/dvd-player.

The success of the Apple iPhone, many mobile phones manufacturers now offer much bigger and better screens than before. As a result watching a whole movie on your mobile is now actually possible without hurting your eyes by a tiny screen, which means that instead of just converting some small clips most users now want to know how to convert a DVD from their collection to a file playable on their iPhone or other mobile device.

DVD-Audio is a standard for storing high quality stereo or multi-channel audio content on a standard DVD disk. A DVD-Audio contains both DVD-Audio content (in the AUDIO_TS folder) and DVD-Video content (in the VIDEO_TS folder) and has the DVD-Audio logo. The audio in the AUDIO_TS folder can be either Linear Pulse Code Modulation (abbreviated LPCM, which is uncompressed) or Meridian Lossless Packing (abbreviated MLP, which is losslessly compressed). Usually, a DVD-Audio contains 5.1ch MLP / 2.0ch MLP or 5.1ch MLP / 2.0ch LPCM. There is also audio present in the VIDEO_TS folder, but of lower quality (that is with a lower sample rate and a lower bit depth). More information can be found here. Supported sample rates range from 44.1KHz up to 192KHz, with bit depths of 16, 20 or 24 bits. (more…)

The Blu-ray Disc (BD) format was developed by most of the same companies that developed DVD. It’s the next generation “HD” version of DVD, where HD means both high density (more storage capacity) and high definition (better video and audio).

BDs come in 25- and 50-Gbyte capacities, which can easily hold hours of high-definition video at resolutions of 1280×720 or 1920×1080 with multichannel audio tracks in compressed or uncompressed format. (more…)

There is only one DVD-Video standard. Within the DVD-Video format there is a great deal of flexibility in the way discs can be created. Different studios have come up with brand names for their particular implementations of advanced features. There’s nothing extraordinary about any particular variation, other than a studio spending a lot of time and effort making it work well and promoting it. These kinds of advanced DVDs should play on most DVD players but may reveal more player bugs than standard discs. (more…)

The following terms may appear at many sites that deal with DVD or video. At this point in time, this short list of terms is not presented in alphabetical order.

- Resolution: The size of the video, as measured in pixels (a digital measurement). (more…)

We like movies! Especially in a fully loaded movie theater, with a sky scraping screen and mega–surround sound that vibrates every part of our bodies. Well now, with DVD player software, you can capture all of the things you love about the theater experience and pack them into your house.

Today’s DVD programs also offer intense, natural color and contrast, empowering your computer screen to display sharp detail during shadowy or highly illuminated scenes. Moreover, with the help of advanced video display features, these programs can keep the picture in focus, instead of clouded or blurred, during rapid scene changes. (more…)
