ssa margins

[joedan]

I have a flat screen tv and my pioneer dvd player is set to 4:3 pan and scan but it seems that no matter what values i put for MarginL, MarginR, MarginV the subs get cut off a bit on the sides.

For example this my ssa that i apply in vdub after resize for svcd:

MarginL, MarginR, MarginV
70,70,30

im pretty sure that the sub clipping i mentioned doesnt occur on other people's tvs as they are much less generous when it comes to the values for left and right margins

does anyone know how i can find out which values are good for my tv?

thanks a lot :D

Well, the program is going to ignore the margins if there's too much text--maybe you could try shrinking the font size?

If you want to measure exactly how much your TV is cutting off the image, play the DVD and freeze-frame on a scene with lots of horizontal detail (like a lot of fence posts), then turn to your computer and grab that same frame from from the video and open it in a image editor so you can compare the two and draw a box the exact size of your TV's image (that's assuming the TV's in the same room as the computer). The overscan range is supposed to be 5 - 10 % of the image size (720x480 or 720x576), so a horizontal margin of 70 is just under 10 %.

thanks for your reply, i did what u said and it has helped me see the overscan :)

i have another question: by increasing the margins, what does that do exactly? does it make it so the text is displayed on a new line so the margins are respected? if that is the case, what's the use of '\n'?

thanks :)

That's right, the margins force the word wrapping. In SSA, "\n" is a "soft" line break, which means "break here if you're sort of thinking about breaking in the general area". If you want to force a line break, use "\N" (yes, SSA is case-sensitive).

the subtitles fit perfectly now :D
