Print to DVD 2 (also!)

[Deeter2]

Have a low Res project with 120-20 minutes (40 hrs total) of training footage. Client wants me to put it on a DVD and author as many as can fit per DVD.
I read on the DVD specs that compliant players should handle the following:
MPEG-2, 525/60 (NTSC): 720x480, 704x480, 352x480, 352x240

However neither PC3 allows DVD encoding, nor Encore nor Sonic (Reel DVD) allows any footage to be placed (and authored) at other than 720x480 which is way too fine detail for this low-res footage... My hope was to have something like 12 hrs of this low res material per DVD....

Am I missing/misinterpreting something?? Been working so much with DV & HD that I forgot!!

Mpeg compression affects file size, not picture size. The picture size remains the same and as you apply compression the number of pixels are reduced.
Depending on the quality of the original you can compress as much as you want but eventually it will be unwatchable.
Rule of thumb is that you can get a maximum of three hours of high quality video on a single DVD and still be able to see it. The best quality is around one hour of video per DVD.

If understand it correctly tough you can also import footage at less than 720x480 (NTSC) while it is one of the other three approved sizes.
Shouldn't its total size then be much smaller if brought in at 352x240 and, yes, also much lower bit rates?? Or will it always display at 720x480? (upsize it)??

Are there alot of talking heads? How much do you plan to fit on a DVD5 in hours? Do you want to use DVD9 also (if budget alows)?

I've done a 2hr 30 min DVD before and had them duplicated (not many copies) and had no problems authoring it in Encore. This was on a DVD5. Mostly talking heads so it looked good.

in this case I recommend half D1, for NTSC it will be 352 wide and 480 high, for Pal it will be 352Wx576H

Tmpgenc4 Xpress can make Half D1 files using all 8 cores

DVD Lab Pro can do Half D1 projects, simply select Half D1 from project properties www.mediachance.com.au

with Half D1, you can use a datarate of 2000-2500kbps allowing for 4 hours on a single layer DVD (use ac3 audio at 192kbps)

OK,
that seems reasonable and I'll try it!!
Thanks
