When we wan burn dvd, the capacity depends on the 120 mins rite? Can we set it depend on the 4.7 Gb? In other words, 120 mins can burn about 4 20mins AVI. If it depend on 4.7GB, we could put more AVI in it. Is it possible?
The capacity of the DVD will depend upon the bitrate used to encode the AVI. Lower bitrate equals more AVI on a DVD but less quality. bitrate and quality go hand in hand. A second possibility would be to burn the AVI as data as long as you have a player capable of playing them. These players are'nt rare but neither are they commonplace, yet.
You can get DVD players that are Xvid/DivX complient at most Wal-Marts, BestBuy, Circut City, etc etc. I have 1 and use DVD-RW. So I can use the disc over and over again after I have watched the AVI file. It makes it simple. Just burn a data DVD watch it when your finished recycle the DVD again with new AVI files you have.
Other then that what mistycat said is corect. Depending on what the bit rate is on the AVI files depends on how many you can get on a DVD5 disc. The lower the bitrate the lower the quaility
But why the DVD i bought from the shop could fit 20 AVI inside plus the quality is good? Is it tat they make it to 7Gb version n they shrink it afterwards?
AVI is a container video format that uses a codec to tell it how to play the audio/video. This is how the file is stored. You can convert the AVI file to DVD compliant files but that makes the file larger and with many AVIs to fit onto a DVD5 you might have to budget what fits and what should be put onto another disk. AVIs are smaller than DVD Compiant files (VOBs, VTS, etc). It's not that they shrink the files down to an AVI.... it's a video format file. Sooooooo it's not being shrunk from a 7Gig down to a 30MB.
