Widescreen --> SVCD???

[kikkegek]

I have found out that I loose the edges of my movie because of overscan on my televisionset.

Now I want to manually convert the movie instead of using "fullscreen, keep aspect ratio" .

But I need to calculate the new resolution for the "Center, Custom size" setting...

The movie is a DIVX of Planet of the Apes 640x272.

I want to convert it to SVCD PAL...Please helkp me...how do I resize this movie so it will have a small black border on the edges so i dont loose any of my movie because of overscan.

Use FitCD. You just put in the resolution of you divx video and it will give you the right resolution for various formats (VCD, SVCD, CVD...). It even has an option for making black borders because of overscan.

I would like to use TMPGENC.

There must be a standard way to come upo with these numbers...there must be some logic to it.


please help

You must experiment. 8) If you use the source range setting in TMPG together with a CDRW you will soon be sorted.

I would start by trying Center (custom size) 464x464(560) together with Full screen - keep aspect ratio, and see how this looks. Basically, it will encode to SVCD resolution but with a small black band around. The aim is to get this to coincide with the overscan region.

If this is not enough, then reduce it some more. I'm not sure whether it is important to reduce resolution in steps of 16, but I am playing safe here.

if i would encode a WIDESCREEN like u say here, using 464x464, I would lose the widescreen format and would end up with a fullscreen format with tall people in it...and thats not what I want.

I have taken the advice from Alf55 and downloaded FitCD...And I will test it overnight ans post the result tomorrow

You are absolutely wrong, since you are already encoding 480x480(576). However, there is no point in giving advice to those who think they already know the anwers.

I won't edit the above, but it is actually wrong, and is explained in the next post.

Having had more time to consider this, with a source avi 640x272, the first dimension for the *custom size* with an SVCD template could be 464. To maintain correct aspect ratio, the second dimension would need to be reduced in proportion to the source, ie to 272x464/640 = 197. This would maintain aspect ratio and encode a black strip 16 pixels wide around the picture, except this would not be noticeable at the top, because it is a widescreen movie.

My initial choice of 476 for both was because the only other time I have used the Center(custom size) setting was to adjust an mpeg-2, rather than an avi.

And having had even more time to consider this, and run some tests, the above also appears to be wrong! Working with the first dimension of 464 is fine, but choosing the second is more problematic. There should be a way to calculate what it should be, rather than using a hit-and-miss approach. So far, all I know is that it is somewhere between 464 and 197.

If anyone has experience of using the custom settings, I would appreciate some feedback. Even though I have no reason to use it, I would like to know how it works. 8)
