Hello, I am prepared to encode the finished video clips (.AVI) to .mpg to author on a dvd.

I am using TMPGEnc DVD Source Creator to do the encoding. The software is asking me if I want to

Encode all clip into one single MPEG file.
or
Encode each clip separatedly to MPEG files.


Which one should I choose to make a life little easier and why? Thanks in advance.

That might depend on what you want to do with the output files
and why the source files are all seperate files.

If the source files represent different movies then you want
different output files as well.

If they are different sections or one single movie it is probably
best to let the program output one large file. If you are going out
to DVD I'm not sure if every authoring application out there
accepts multiple input files for the same movie (most do I think).

So you might be able to use different files for the same movie as
well, but I'm not sure what the benefit would be.
