Loss of quality if I import of a DVD movies and burn again
Frage von Grintolix: Oktober 2006
I had times when a fundamental question. If I (as with DVD MovieFactory) of a privately produced DVD (eg wedding film) a movie import, edit and do not burn again, do I quality from a 1:1 copy of the original DVD or do I then have a quality loss?
Easy DVD> DVD copy here is not because I (import from multiple DVD's Movies about 5 to 10 minutes) and would want to create a new menu with a DVD.
... and how it looks when I cut the (of the DVD imported) movie file may be re-encode. Have I then have a quality loss?
Antwort von steveb:
there was a tool chopperxp. it cuts parts out of DVDs. Then just rename them to mpeg and lead again in cutting program together.
If you cut the film (including effects) re-prints, they are synonymous and are thus rendered again with losses forever.

I'm not quite sure.
Try out the following:
Import a DVD. Cut away what you do not need, preferably without s.den I-frames. Import the next DVD, as a with different bit rate for the test. Cutting away again, what you need nich.
Now you have two clips. Create your menu and do everything as usual eighth but the fact that the function "Do not recalculate" is checked.
The DVD MovieFactory is really only re-render, if there should be other changes. That this is so, you recognize it, how long it takes :-)
Generates only a new VOB structure and then fired, you have no loss of quality synonymous.
But is re-rendered, then you have definitely a quality loss, because the soup still may be, but the soup from the rest of the soup just no longer tastes like the soup, which answered your second question.
Antwort von Grintolix:
Thank times before.
Ok ... I have since adopted a DVD. Then two movies (with are effects, titles, etc ,...) I like that menu, but not because of clerical drinne are. I import this DVD of the film, create a new menu, and burn again. The DVD MovieFactory is activated, that DVD format (to be taken over or something like that). So I should thus have a 1:1 copy of the footage without quality loss, right?
Antwort von beiti:
Very sure it works if you use an authoring program that even has no native encoder (such as DVD-Lab).
Antwort von StefanS:
Please try yourself and see just as I have described it to you. I said that I am not quite sure because I never do so, but it would, in my knowledge of the Filbrennerei so.
