I know that MPEG-2 is what the DVD is burned as, but what is the best format of the clip to be burned to the DVD? AVI, MPEG-2...?
In other words, do you create the video file of a completed project to MPEG-2 and then burn that to the disc, or create video file as an AVI and then the authoring software encodes it to MPEG-2 during the burning process?
Does it matter?
Still learning the ropes, so sorry if this is a no-brainer question.
In case it matters, I'm using MSP 8 w/hot-fix.
File type for burning to DVD
That would depend on what type of editing you are doing to the original source video. If you are doing straight cuts, then it would make no difference (as long as you output to the same .avi format as the source videos).
But if you have edits such as overlays, transitions, text, etc..., then by going to .avi first, then to mpeg, you have introduced an "extra" encode of your video -- which may be viewable to the end user (it might not make a difference either depending on your final encoding bitrates for dvd).
But, if you're like me and you make a backup of a dv .avi, then I output to my hard drive as dv .avi. I can then export that to tape (for longterm backup). I can also just encode the resulting dv .avi and use it in my authoring program.

That's what I thought. I least I think. Tell me if this sounds right...
If burning an MPEG-2 to disc, there isn't any encoding going on, per say, it's just burning that file to the disc.
If burning an AVI to disc, the authoring software first must encode it as an MPEG-2 for placement on the disc, so it's almost like it's taking an extra step.
Is that, in a simplified way I'm sure, what happens?
Also, I didn't follow what you meant here, "make a backup of a dv .avi, then I output to my hard drive as dv .avi." What are you putting the backup on? A DVD? Sorry, if I'm being dense.

I export the dv .avi back out to dv tape for long term storage.
The video needs to be encoded to mpeg for standard DVD Authoring. So either way you will have to do it at least once. Ulead's authoring programs can use a dvd spec mpeg "asis" (i.e. no re-encoding), or it can be told to re-encode the input files (even if they are already DVD Compliant mpeg streams).
So, try to avoid unnecessary encoding whenever possible...
Some Authoring applications do NOT include an mpeg encoder -- they expect compliant video/audio streams. Ulead gives you an option because their Authoring applications include an mpeg encoder...
