I have a 14GB HDV MPEG2 file and I want to put that into a 4.7GB regular DVD?. I know I can only put up to 4.7GB into the DVD so what is the best compression out there that would do the job and still have good quality to it?.
Do you need to be able to play this DVD in a regular DVD player?
If so the only compression you can use is mpeg-2.
Have you considered using a dual layer DVD?
If you just want to put it onto the DVD as a data file to tranport it to say someone else you could split it into smaller parts losslessly with Vegas.
Or maybe you want to play it out as HD?
WMV doesn't look too shabby, plays out pretty easily on most PCs today.
Probably if we new more about what your needs are we could come up with a more specific answer.
I guess the higher the bitrate the better. I try to keep it within reason though. 720p @ 5Mb/sec looks pretty good and almost any player can keep up. At that speed you should be able to play it off a DVD. Much higher and the drive mightn't keep up and you need to copy the file to a HDD.
Aside from that I've not done any research into how to wrangle the last ounce out of WMV. I find with good source the bog standard 5M template looks great if I wind the quality slider all the way up.
A the same time for my digital signage tests I've gone down to 1 Mb/sec @ 1080p with perfect results but most of the frame is static.
