Know the size of the DVD format, commonly known as PAL and NTSC formats. Generally the duration of your DVD movies about 2 hours and stored in a media type single-layer DVD disc capacity of 4.7GB. Or dual layer DVD that can accommodate a single-layer DVD capacity 2X
Whether it is a standard size like that. Will it be a single layer DVDs out of bounds by showing movies more than 2 hours. How to save a movie with a duration of 3 to 4 hours. So what should be done and their impact to create a DVD disc for more accommodate the duration of a movie.

For the current analysis that led to the capacity of DVD is the size BitRate enlarged. DVD movie picture sharpness seems to depend on the size of BitRate. By BitRate will be able to minimize the effort to save a DVD movie duration is greater than 2 hours.
With a standard format, a DVD movie will use Constant BitRate (bit rate fixed amount). Do you have a movie that has a resolution quality good or less good. Everything will be entered into the highest setting of the DVD. The impact of a film that fits onto a single-layer DVD Disc media will be limited to between 1-2 hours.
But it turns out the DVD file size can be changed by playing the numbers BitRate. BitRate own function is to maintain the quality of the picture or to maintain the best image resolution in accordance with the original quality. Suppose you have a film from the H.264 format which is higher and sharper bersolusi otherwise known as HD format of 720p or maybe even higher. To convert the film from the H.264 format should take advantage of setting a maximum level BitRate. So that quality can be maintained close to the original film.
What if you were not a movie-quality HD, or even lower than DVD resolution itself. Suppose you have a movie to VCD or video format with mediocre quality and the quality is still below the DVD. Or you have a film or video and want to be made into a DVD, without prioritize the best picture quality. Following technique can be a solution in the process of editing the file DVD. So that the converted files into smaller, and DVD movies can contain more premises running longer duration.
BitRate adjust the size of DVD files
DVD has 2 sizes of Constant Bitrate and BitRate Variable BitRate. This format can be adjusted according to actual needs, and impact on image quality.
Constant BitRate (CBR) is a fixed rate for each frame size per second. CBR format like this can be used to maintain image quality when the kompresing done. Image files will not be reduced if not compress or reach the point of 6MB / s but did not cross the line 9MB / s. With the CBR system, image quality maintained and sharper, but it produces larger file sizes.
Variable BitRate (VBR) has 3 limitations that is above average and below. The file will be maintained for a file to DVD is at 3 specified limits. It could even take the minimum figure if a DVD movie made to minimize the size. During the process of change a video file into DVD format, then the Variable BitRate will move dynamically and follows three pre-set limits. Are you going to make a DVD movie picture quality with high resolution or low level. This is where BitRate Varible function that allows to dynamically adjust how much the size of a frame from the movie DVD. And the picture will look to have a dynamic quality. Although the VBR system will reduce the Rev the image quality, the downside will be seen less sharply in the moving object when it aired. But on the benefits and needs, VBR system can reduce the size of the resulting file on a DVD. So a movie with a limited conversion to VBR will be smaller and save storage media. Surely with a smaller size, the film can be entered into more DVD media.
How to set BitRate DVD formats through editing software
Any video editing software generally includes BitRate size. In addition to video editing software, there is also software that works to change all kinds of video files to DVD also provides a setting BitRate. Examples below are some video file conversion software that includes features BitRate.
TMPGEnc 4.0 XPress software has a very flexible system in the regulation BitRate to convert a movie. .
Options will be opened when the setting in the image above in the click. And perform Windows as below. BitRate rules can be adjusted as needed, from 2000 to the minimum and maximum numbers up to 8000Kb / s. When you want to reduce the size of a DVD, can be set by equating the upper limit of the size of a lower limit. For example, the upper limit is made 2000Kb / s and the same as setting the lower limit of 2000Kb / s
MediaVideoConverter HD Video Converter (picture left) and Xilisoft Video Converter Ultimate 6 (picture right) has the same function.
MediaVideoConverter HD Video Converter, has a rule setting BitRate average from 3000-8000Kb / s. While the upper and lower limits created open
Xilisoft Video Converter Ultimate 6, has a Constant BitRate BitRate with numbers. From 2500 up to 10000Kb / s.
Pictured above are some examples of settings or options settings in the process of converting video files / movies to DVD format.
How to adjust sound on DVD format
To set sounds, the standard DVD format with stereo format using two different audio formats. Can use AC3 or Dolby and another one is MP3. Audio format that produces the smallest file size is AC3, besides the ability to reach 48KHz output. While the MP3 will produce larger files with maximum quality at 44Khz.
Both the audio format will be accompanying sound structure of a movie. The size of a DVD file is also added with MP3 or AC3 audio files.
When converting audio formats include MP3, certainly will produce a DVD movie file is bigger than using AC3 audio format. Just select AC3 according to the standard DVD format, but reduce the bitrate up to 128K
Experiments in various BitRate a film that is converted into formatDVD
Examples in the following experiment. A movie with H.264 / AVI with 1080x720p resolution 16:9 widescreen type with a duration of 25 seconds. By changing the file by using various formats BitRate below, to produce a DVD file size (output MPG) is different.
Smallest file size looks to be on the setting BitRate 2MB and only produce output between 6-7MB for a duration of 25 seconds movie.
The central point is BitRate 4MB, produces an output file between 12MB to 25 seconds length movies.
Highest BitRate certainly the largest that is 9MB, an output between 28-29MB.
If the above simulation results are calculated into a movie long enough, the result will produce different file size difference. Test below for comparison with DVD NTSC output settings 29.9fps, 16:9 screen, but turn off the sound file. To limit the size of 4.7GB capacity of DVD discs.
2MB BitRate format can be accommodated by the DVD more than 3 hours.
Format BitRate 4MB can be accommodated by the DVD to 2.5 hours
BitRate 9MB Format DVD can only be accommodated in less than 2 hours
What is really effective when a film compressed with BitRate smallest, and can enter the duration of the movie more into a DVD Disc media. The result in the picture below, looks a player who shows the number of 4 hours 38 minutes and 30 seconds. This means the Media DVD can accommodate films with a duration of 4 hours and can fit all the files into the disc.

Advantages and disadvantages of playing BitRate for DVD media
Memainakan BitRate numbers to minimize the size of DVD files can save space on the DVD disc. The size of the film can be reduced to half so that the DVD disc can accommodate films with a longer duration.
The side of excess with a small BitRate
Minimizing the size of video files / movies on the conversion to DVD. Media Disc DVD is limited to accommodate a longer duration of the film.
Better used to convert movies with fixed objects. Such as training videos, tutorials.
Better used for films with lower resolution. As the converted videos VCD to DVD, mobile phones and other picture-quality DVD format below.
It would be very effective if you want to load more of the duration of a Disc DVD and does not emphasize the quality of the existing film.
Deficiency with a small side BitRate
When you put quality on the results, you should not use low BitRate. Because it will reduce the sharpness of the image.
In some tests, the deficiency with a small BitRate Mozaik will produce images on the screen. Especially in a movie where a lot of fields or objects relieve oneself.
How BitRate size you need, once again see the return of the films have to be converted to DVD. Whether to prioritize the quality or capacity of a DVD Disc media.
When speaking of quality, should keep the DVD format at the highest level BitRate. So the quality of the film will remain intact. Conversely, if not concerned with the quality of the movie or the original source of the film to be converted appears to have a lower resolution. By selecting the lowest setting will reduce output BitRate film converted to DVD.
