I found a vobsub file having very good anti-alias ratio
but i couldn't figure out how is it possible to obtain such ratio...

the strategy is almost like anti-alias
But you can also called it double outline with 2 color
the inner 1 is pure black while the outer 1 is dark grayish black

This Subtitle image is Extracted From Region 3 Taiwan Commercial DVD
Where i replace the dark Gray Outline with red for you guys to see
Original color before i replace red for everyone to see the inner black outline
Outline = Dark Gray 1f1f1f
Anti-Alias = Black 000000
Body = Grayish White e5e5e5
BG = redish e63f07

Can you paste an unmodified picture of what it looks like during playback?

sure, there you go.
P/S:to preserve the subtitle quality i save the sample images to png24, sorry for the size, 200kb~400kb

I'm thinking the professional level tools (subtitle company) for commercial DVD use feature slightly different from what is available for free currently on the net, for this double outline features or shadowed subtitle

but i'm thinking if we couldn't do double outline or shadow in maestroSBT,
could we do a adobe photoshop batch script->automated process filtering all images in SST folder to either double outline or shadow where you see in commercial DVD

i only know how to automate 3000 images if transparent BG to add shadow or (inner outline/outerline) but i doesn't have knowledge to work with opaque background BMP

I'll take your word for it, because I can only see 1 outline color on those 2 PNGs.

You can do antialiasing in MaestroSBT, just set Color rendering to "Only one set of text, antialias and outline colors" in the Rendering options. Then in the Style editor, threshold 1 affects horizontal aliasing, and threshold 2 affects vertical aliasing. Play with those two values, along with the "Text %" parameter and the font size, until you find a good setting.

by looking at the images you cannot see the anti-alias
but when you look into the .sup you can see that the outline is around 1px softer round the entire letter.

for maestrosbt is because i keep playing with it and find that i couldn't figure out how to get 1 px all around inside the outline
i only seems to be able to get jaggled curve edges anti-alias but not for straight line horizontal or vertical...

thats the reason i posted asking for ratio setting in maestroSBT ^^~

Edited:
if you are still with me, let me go into more details
