A lower -q (2 or 3) gets me higher file sizes, so shouldn't it also be potentially better quality?
Yes, it will give better quality. That may or may not be visible :)
I have a problem with -q 2 and 3. See seperate thread.
Ah, it's letterboxed so you have large areas of solid black (60 lines
above and below the 360 active lines). That explains the low average
bitrate.
:-)
I tried -f 8 -q 4 -b 4000 -K tmpgenc -D 10 and got 710 MB file size. Any
Well, '-K tmpgenc' lowers the average bitrate so that explains why the file is smaller than the first encoding (which came out to 950MB).
There was no first encoding. This was just my target size.
recommendations? Is it logical to reduce -q further until I get to my wanted file size, if -b can be kept 25% above the average?
Normally folks are interested in lowering the bitrate so that the files are smaller ;)
It's just that I want to fit 4 of these movies on one DVD. So, I'd like to have the best possible quality for the available space.
If you really want to make larger files then try something like this:
mpeg2enc -f 8 -q 4 -K hi-res -D 10 -E -8 -2 1
If the file is still too small then try '-q 3' and see what happens. You may want to add '-b 8500' to allow a higher bitrate than the default 7500 .
OK, thanks.
