AIW MPEG-2 capture from VHS for DVD-9?

[colony]

Hello All,

I've seen the posts from sanlyn and others talking about VHS/Hi-8 MPEG capture for burning to 4.7 GB discs; also Lord Smurf's suggestion for archiving at 10 GB/hr.

What about burning to double layer DVD-9 discs? Is there an advantage over 4.7 discs given less compression? What capture settings would work for movies recorded to VHS from TV/Sat? Should I use output size of 720x480 for NTSC and 720x576 for PAL ?

I've never mentioned 10gb/hour for DVD, aside from it (maybe) being an average data size, for whatever that conversation was. Instead, pay attention to bitrate.

DVD-Video is capped at 9.8mbps audio+video, so that's the max. It will yield about 1.5 hours on a DVD9 (DVD+R DL).

Max SD, and for DVD-Video, is also capped at 720x480-576.

I often use 352x480, especially using DVD recorders, even now, to record B&W movies, game shows, and cartoons to HDD. Transfer to DVD, rip to computer, edit, store on network share as MPEG. Just 4x3 content, rarely 16x9.

Thanks Lord Smurf!

Yes, that suggestion of yours was for saving to hard drive at broadcast bitrate, avg 10GB/hour (15mbps).

Pardon my lack of understanding here but I believe one of the capturing guides has graphs that portray useful bitrates, with 7-8 mbps being the upper range of useful for 720x480, and you indicate 9.8 mbps is the max possible for DVD-Video. In that bandwidth of 9.8 down to 7 mbps (or if I understand, lower when using 352x480), am I able to capture 2-2.5 hours of VHS recordings (1 tape at SP, or 2 hour segments of a tape at EP) for authoring and burning to a single DVD+R DL?
Do PAL captures alter bitrate requirements? Again thanks.
