I’ve been backing up my DVDs to my PCH & NAS, … and have been using DVDFab using Generic, … using generic.avo.xvid.audiocopy , and per Gregiboys recommendation I’ve been keeping the Bitrate slider between 1100 - 1500. On some avis though, … I still see those compression blocks in the shadow areas, etc … on the TV. (these avi files are 1.5g or thereabouts in size)
My question is, … if I had done the avi at say 1300 bitrate, what whould improve the quality the most if I were to re-convert the DVD? … going up on the bitrate to either 1500 or 1700, … or selecting 2 pass instead of 1 pass?
Another question, … I’ve seen other avi files of DVDs, that are only 700M in file size, … yet I don’t see as many blocky artifacts as I do using my process, and my files are twice as big. Are these other guys using a different program? (is it possible to tell what codec, settings are used on these avi’s?)
If I had the Hard Drive space, I would just backup the videos w/o compression, … but I don’t have the luxury for that yet.
thanks for any help, or links that might help me figure this out.
ONe last question, … I’ve noticed that DVDFab seems to pick a particular bitrate when you go to the Configure screen. Is there any significance to this number?
On a particular DVD, Polar Express …
avi.h264.audiocopy shows 768 bitrate and 873M file size
avi.h264.mp3 shows 900 bitrate and 691M Fiile Size
avi.xvid.audiocopy shows 999 bitrate and 1037M file size
Would using h264.audiocopy and upping the bitrate to 1300 be better than using xvid and upping the bitrate to 1300?
Sorry if these questions are NEWB in nature, … as I’m trying to learn.
