What to use for Source Aspect Ratio
 
If I am using the PAL KVCD template to encode to 16:9, what should I use in the MPEG Settings-Advanced -Video source setting - Source Aspect Ratio: "16:9 Display" or "16:9 625 line (PAL)".

Since I know that the readavs.dll processes the source, I am getting confused. I think both should work fine, but still I need to choose one!!!.

If you use "Center" or "Fullscreen" as we always suggest, you can choose whatever you want in the Source A/R, this is not used ;-)

I like watching my vids in 16:9 ratio when that if that is the source. If I use "full screen (keep aspect ratio)" will that affect the quality of my kvcd encode? Does it matter what I choose for the stream output? Thanks. :D

Yes it will :!:
Full screen movies have far more bits than wide screen, so more bitrate is needed to maintain quality.

Hi

I too am a little confused on this point too

I have a movie that i've backed up run thru dvd2avi display reads:

4:3
PAL
F/R 25

So when i open it in TMPGE what should i have the settings on

Video:
4:3 625 line (PAL)
F/R 25

Advanced:
4:3 625 line (PAL)
Full Screen (keep aspect ratio)

:?

I also have the same problem when display reads 16:9 in dvd2avi. Because there are so many choices in the advanced tab i'm playing enie meeenie minie mo and the finished product either comes out too big in file size or i end up with a little rectangle box in the middle of the screen :(

Your expertise would be greatly appreciated :D

First of all : are you using an avisynth script or not ?

hmm

Apologies for lack of information on my part

I've never heard of it so i guess not :?

I just usually run movie thru PowerDVD > after 20 sec start Smart Ripper > add VOB files to dvd2avi and then open the 2dv. and audio in TMPGE load a KVCD (NTSC) 120 Minutes template then try 'very unsuccesfully' to alter settings like a/r and cq myself

Ok, so you don't use avisynth else that is not the d2v file that is used as source then, but the avisynth script.
The setting you are using are correct then, I don't see how you can end up with a small rectangleas you mention. The best is, when you will have the problem again, to put a snapshot of the encoded video, and of the settings in tmgenc.
