[gentoo-user] [OT] Specifying file size in dvd::rip

I am trying out dvd::rip as kindly suggested in this mailing list, but cannot 
find a way of specifying the target file size.  When I fill in 4700MB in the 
Transcode tab (under target size) it is invariably ignored and I get only 
2.2-3.5G avi file sizes out of the whole process.  In this way I end up with 
half empty DVDs (I want to save the avi file onto a 4.7G DVD) which lack 
colour detail - it's difficult to explain but grey or dark colours create a 
silvery/shadowing effect.

How do you set dvd::rip to end up with a 16:9 aspect avi file taking up close 
to (but no more than) 4.7G?

It's really pretty unusual to make avis that large. Are you using XviD? 
There is a maximum quality you can achieve with each codec. With 4.7 GB 
target size, you could as well use MPEG2. Or try h264 (wild guess, but 
this is the codec with the best quality in linuxland atm).

Thanks Thomas,

Yes, I am using xvid which is using the h263 quantization method by default.  
Should I choose mpeg instead of h263?

Other codecs offered by dvd::rip are:

vidx4
vidx5
xvid
xvid2
xvid3
xvid4
ffmpeg
fame
af6

xvid is the default codec selection.  I can't find h264 in the transcode 
options.

Without going into too much detail, that's something different. XviD is 
a dialect of MPEG-4. H.264 is a different, newer standard. MPEG-2 is yet 
another standard used on DVD's (=ooold ;-)). Hardware players can do 
MPEG-2, some can do DivX/some parts of MPEG-4 and XviD if you are 
careful not to enable the advanced coding options. I know of none doing 
H.264.

Then there are containers: mp2 (only mpeg2), mp4 (only mpeg4), avi 
(anything, but limited), ogg (anything), mkv (anything and more, not in 
DVD::Rip last time I checked).

If you don't care about HW players, you might find ogg a better 
container format then avi (uses less space, audio/video don't get out of 
sync as easily, multiple Audio tracks/subtitels supported...).

Hm, or stay with avi, I don't want to confuse you. All of this is a bit 
of voodoo. :)

ffmpeg does, it's a library providing different codecs.

Thanks, I'll try ogg next to see if there is a difference on my laptop.  I 
noticed that a lot of artifacts which are visible on the desktop (with its 
crt monitor) are not showing at all on the laptop.

Tell me about it!  It can be a bit daunting for the uninitiated.

Thanks again for your help.  :)

A quick comparison can be found at 
http://en.wikipedia.org/wiki/Comparison_of_container_formats .  I believe 
Matroska should be used whenever possible, but I don't know any any 
standalone players that support it right now.

There's a matroska USE flag, but as you say, I don't think any (stable) 
packages use it yet.

No, I meant stand-alone as in a device that only plays disks.  A DVD player 
or DVD/Blu-Ray player or DVD/HD-DVD player or similar "consumer 
electronics" device.

Both kmplayer (mplayer/xine) and kaffeine (xine/gstreamer/mplayer) 
play .mkv files fine on my system.

In fact, MPlayer is gaining excellent support for Matroska as well.  It 
already includes stuff like chapter support.
