Dvd-r TIME

[f1re]

I bought a pack of TDK dvd-r 4x 4.7gb and on the back it has:
RECORD MODE:
FINE=60mins
SP=2hrs
LP=4hrs
EP=6Hrs
Its also states : Altought standard recording is 120mins (SP MODE) the recording time can vary depending on the recorder and or record mode in use"

I guessed this meant how long the dvd can hold of video if used ona dvd player witha recoreder as it has EP(Extenedted play) just like my video cassett recoreder. Is there anyway to get these long playing tiem capibiltiy ona pc burner? it would be great to have like 6hrs on 1 dvd!.
Or does this method of extedned play,long play etc only applies the dvd player reocrders? CASue when i burnvid to dvd i can only fit 120mins worth.

thnks

The same thing is printed on all DVDRs and makes sense only for standalone DVD recorders that have only a limited number of settings like SP/LP/EP similar to VCR, in which case there is nothing you can do. When you make your own video, for example with a capture card, the only thing that matters is bitrate i.e. how many bits are being recorded per second. The lower the bitrate, the more you can fit on disc, but the quality get lower. Most of MPEG encoders utilize VBR (variable bitrate) technique, which reflect the fact that in order to encode the scenes with equal quality in MPEG file, it requires higher bitrate for the scenes with a lot of motion, and lower bitrate for the still scenes. As a result, total time you can fit on one disc depends on the video. Again, if you capture your video yourself, you can reduce bitrate by reducing the screen resolution from 720*480 for standard NTSC DVD to 352*480 or even 352*240 (VHS quality). If you're making a DVD backup, you can only increase video compression as much as you want as long as you consider the result to be of acceptable quality.

Probably Mods should move this to Newbies forum.

WHen i backup and if the dvd is larger that 4.7gb i use dvd shrink. Does dvd shrink affect the quailty that much? In otehr words, will dvd shrink make the quality wrost as the compression gets larger. Thankyou alot adn sorry if i am causing trouble, i am a newbie.

Members of the Copyright Mafia (like GEMA, RIAA) receive a fee per sold DVD+-R, and this fee is defined in cent per minute recording time.

Those 120 mins are nothing else than the time the fee is calculated for.

That's why people often remove extras or back up the main movie only to reduce the size of the original and thus reduce compression level as much as possible. In DVD Shrink, you may consider the compression values shown as estimated quality of the backup: 100% is the original quality; the lower this percentage goes, the worse the picture gets.
