At first glance it may seem that the average computer user video coding is not required.Office applications, games and movies run, the browser opens the page successfully online.Well, the video encoding of information - it is the prerogative of people whose profession is associated with the editing and processing of such data streams.Some will be a revelation, but this view is mistaken.That's because video encoding is sometimes claimed.The reasons may be very different: the need to reduce the volume occupied by the file before conversion to "understand" hardware DVD-player format.Since flexibility is achieved by a computer mounted with a corresponding applications, the program for video encoding must necessarily be present among them.
such decisions there is a huge amount: from complex trade packages that allow to adjust the minute details of the codec, to relatively simple programs that use the banal Drag & amp; Drop.We propose to pay attention to quite a good solution - VirtualDub (or its modification - Mod).With this application video encoding is converted into an understandable and accessible operation.
So, suppose that the task to the user to reduce the amount of video as possible while maintaining the original quality.After starting the program, open the original file.To do this, use the command appropriate menu item in the "cap".If the performance of the CPU is not sufficient, we will have to wait until the internal codes will be scanned.
little to accelerate the work program can be achieved by making adjustments to the settings.For example, it is useful to activate the mechanisms of frame skipping (Drop Frame), synchronization of audio and video streams (Sync audio), including hardware overlay processing (Allow overlays).Also worth a try to use a new feature of using a three-dimensional acceleration, located along the path «Option - Preferences - 3D accel».
open the file and tune performance, you should select the codec with which to encode the video.If you do not require the use of additional features of the program, it is permissible to choose a fast (Fast) or normal (Normal) mode.So, if the concept of «Color Depth» user nothing says it is acceptable to use «Fast».Next to continue work in the Video menu to choose full processing mode - Full processing.After that unlocks the choice of compression (a combination of Ctrl + P).In the left window a list of available codecs installed in the operating system.Before you start working with the program is recommended to install codec pack, for example, the famous K-Lite.After selecting the desired (one of the most popular - DivX), should be configured to select the bit rate.The higher the number, the less loss of quality, but the larger the size of the output file.Opinions on how much is enough, divided.Probably less than 800 should not be followed.You can also use two-pass encoding.It improves video quality, but requires more time to complete the process.After making changes, you must click "OK" in the menu «File» to specify save as AVI.
