Question about recording on a dvd-r 60 or 120 minutes.

[sentenced2000]

Hi there...here's Jose Luis from Mexico. I hope you can help me... I'm ready to send some VHS and LASERDISCS to a local video transfer place and put them on DVD-R. The store clerk said me that if i just want to transfer 60 minutes of video to a DVD-R the image will be fantastic---as the original--great, but i told him that i have a lot of concerts that runs over 60minutes...to said, 80, 95, 110 or even 2 hours. He said that if he extend the recording time more that 60 minutes the image will not be so perfect...that a lot of blocks and pixels will appear....in a few words, the resultant video is comparable to a regular svcd or a little worse...is this true????? if so, then whats the advantage of the dvd if the quality of a vhs will be the same or better (and i save a lot of bucks), or even a shitty vcd will do the work....in a few words, what will be the percentage of degradation between an original video and the final dvdr on over 60 minute recording time...????

Your man is talking bullshit.

I've put up 4 hours (240 min) on DVD-R using CCE with 3 pass vbr and the quality is very good. Sources are DVD, TV Capture and DV camera.

Depending of the action on the screen you might want to put less... 3 hours is a pretty good average and if it's really moving and flashing all over the place then 2 hours will do.

I record concert myself from TV and all is fine between 3 hours and 4 hours.

The man must have a shitty encoder and use CBR (constant bitrate) or is trying to sell you more blank DVD-R to charge you more.

For VHS transfer, 352x480 @ 4Mb/sec is more than enough to get the same quality as the VHS video tape. That will give you more than 2 hours on a DVD-R. As for laser disk, then I would go with 720x480 @ 5Mb, or use VBR mode with peaks up to 9Mb/sec and an average of 4 mb/sec. This should give you up to 2 hours per disk.
I am assuming off-line encoding, and not real-time encoding.
