Hi, There are 4 Different Resolutions that you can use to Make a DVD and with these other Resolutions you Can Fit Much More on a DVD because these Lower resolutions Need a Lower
bitrate to Encode so I suggest that you Try them when Trying to Fit say more than 2.5 Hours on a DVD...
These are all of the DVD Standards and Resolutions and Aproximate
bitrate needed to encode to Good Quality useing these Resolutions...
The First one is the Standard Resolution used on Most retail DVD"s...
Standard.....Resolution......
bitrate Needed.....Minutes per DVD...
Full D1 .... 720+480 ......3800 to 6500kbs ....90 min to 2.5 hours..
Broadcast D1. 704+480 .....The rest is the same as Full D1....
Half D1 .....352+480 ......2000kbs to 3000kbs ...3 to 4.5 Hours....
SIF/CIF .... 352+240 ......1100kbs to 2000kbs ...4.5 to 7.5 Hours....
The Half D1 Standard produces Quality about as Good as a Very Good
SVCD so it is Pretty Close to Full DVD quality as Long as you use a Good Quality Encoder that is Set up Properly for the Type of File you are encodeing....
The SIF/CIF DVD Standard Uses the Same Resolution as
VCD accept that you can use Mpeg-2 and a Higher
bitrate so the Quality you can Get with the SIF/CIF Standard is Better than
VCD Standard and Might even be Closer to
SVCD if Made from a Very Good Source File and a High enought
bitrate.....
To use these Other DVD Standards you will need to use a DVD Authoring Program that supports all of the DVD Standards Because Many of the Consumer oriented DVD authoring Programs only Support the Full D1 Standard and Will re-encode the File so it is Full D1 which Wastes Time and Ruins Quality....
I use the Half D1 and the SIF/CIF standards Quite Often especially when I am working With Low resolution Source Files and they produce acceptable Results....
I"m not sure if your Card Can Capture to Half D1 or SIF/CIF but it sould in which case I would give them a Try if you want to Fit as Much on a DVD as Possible Without Sacrificeing Too Much Quality....
Cheers
