Importing from DVD

Reading through the posting - I should not import my source video as mpeg. I can't find how to save them as AVI when my source is a DVD.

I'm using VS9 - Very little experience with this program

Thanks

DVDs are MPEG, so they are going to be imported without any re-coding.* There may be some re-formatting of the file, but the actual data that makes-up the video will stay intact. You can make a DVD from that MPEG file with no deterioration of the video quality.

You will get degradation if you edit the file in a way that requires a decode/re-code cycle, and you can get the dreaded "lip-sync" problem.

Once you have an MPEG file, you can save it as AVI/DV. This might solve the sync problems. Somebody here suggested that after I bought a special-purpose MPEG editor.

Of course, if you later make a DVD from that AVI/DV, you will have to perform the additional (lossy) MPEG re-code.

* DVDs use MPEG-2 compression. They are not .MPG files. They are .VOB files. Sometimes you can change the file name to .MPG, and open it as an MPG file... But, there are different "rules" for the underlying file structures... I think.
