OK, I would say that this is a PAL DVD with mp3 sound, based on the |
16 |
aspect ratio, frame rate, and size. You *could* just use dvdauthor to |
17 |
format the mpg (which is correctly formatted for a PAL DVD) to |
18 |
DVD-compliant files, and then burn it to a standard DVD which would |
19 |
happily play in your DVD player (assuming that said player can play PAL |
20 |
DVDs). |
21 |
|
22 |
But if you don't have a DVD burner, or for some other reason need this |
23 |
file to be housed on smaller media, you need to break the file up into |
24 |
its composite parts so that you can get rid of some of them. For |
25 |
example, if there are menus, they need to be ripped out. If there |
26 |
are extras (making-of comments, outtakes, whatever), they need to be |
27 |
ripped out. What I would do is fire up dvdauthor to convert the *.mpg |
28 |
into defined chapters (*.VOB and *.IFO files), then fire up dvd::rip to |
29 |
select just the data chapters (the "movie" itself, in other words, without |
30 |
the menus and extras), and transcode those chapters to an *avi... in the |
31 |
process you could also reduce the sound quality somewhat, which would |
32 |
also reduce the final file size, and of course the image size, which |
33 |
would reduce the file size as well, but it might not look very good. |
34 |
|
35 |
Alternatively, if it's a 'mixed' DVD (for example, not a movie, but a |
36 |
music/concert DVD with video footage), using the chapter methodology would |
37 |
enable you to encode each video/song as an individual *.avi rather than one |
38 |
giant one. |
39 |
|
40 |
If you tell dvdrip how big you want the resulting transcoded file to be, |
41 |
it will do that, but if all of the data doesn't fit in the size |
42 |
specified (which it likely won't, depending on your settings, which can |
43 |
only do so much), then you'll have two (or four, or six) 100MB files |
44 |
instead of just one. |
45 |
|
46 |
That's about the best I can do for you without knowing more about the |
47 |
construction of the file, and what you're trying to do with it. |
