Source Aspect Ratio

[Hardeep_S]

I'm encoding a video in TMPG. THe avi file is 576x240. When you select your souce file, what should i chose for aspect ratio, 1:1 (VGA) or 16:9 525 line (NTSC). In the MPEG settings, for video arrange method i chose Full Screen (keep aspect ratio).

Which aspect ratio should i chose for my source file?

1:1 VGA or 16:9 525 line (ntsc)

ps.: I'm converting it over to SVCD.

What about avi's that are 640x272, 576x320, or 608x256

What should i choose the aspect ratio for the source file for them
converting them to SVCD and for video arrange method, choosing full screen (keep aspect ratio)

One more thing, my tv is fullscreen

I read it and it is kind confusing. I just need a simple answer. Should i use 1:1 VGA or 16:9 (NTSC) for my source aspect ration when the original avi is widescreen.

Source Aspect Ratio. I'm sorry for my spelling.

If you have a 576x320 avi file, then it's 16:9.

What about the other resolutions?

Yeah sort of, to me if your going to encode something in 16:9 in 640x then it should be 640x360. But basically yeah it's 16:9.
