I am sorry for this one, but here it goes. I am in deep doubt on how to resize movies (mainly AVI) to SVCD. For DVD, my calculations are :

640/FilmWidth*FilmHeigth ; Then I add borders to make up for 480 in height, when needed ; Then I do an Avisynth with ..Resize(720,CalculatedValue).

No problem with this. But, with SVCD I was told to do this :

720 / FilmWidth * FilmHeight * (10/11). But, when I do this calc for some films I get too big heights. I would like to know the correct way to resize. As examples, can anyone help me with these films ?

512x384
640x352
512x288

A simple formula can do it, I know. Also, should I change the calculation for KVCD ?

TMPGEnc alone is not answer as I need to use Avisynth filters... Would love to resize in Avisynth, too.

Thanks in advance...

There is a detailed guide on resizing and apsect ratios in the userguides forum. It was written by DJRumpy, take a look.

Thanks, bugster. This guide I already know by neart, but my brain is not that much endowed and I still do not know the thing 100%. After all my reading I guesse I have to resize the video to 480 height and forget about the width if the movie is already 4:3. Otherwise, make width 640 and fill up the height with borders.

Anyways, thanks.

Well the easiest way is to let TMPGenc do the resizing - it does the adjustments for you.

You can still have all your other AVISYNTH filters just don't have any re-size or border filters activated.

In TMPGenc load your 'AVS' script file or 'AVI' file and select the appropriate 'SVCD' template (or use the wizards).

Go to the 'Settings' option in TMPGenc and select the 'Advanced' tab.
Under 'Video Source Setting',
- Leave the 'Source aspect ratio' as '1:1 (VGA)'
- Set the 'Video Arrange Method' to 'Full screen (keep aspect ratio)'.

Now do your rendering and the SVCD should play back in the correct ratio.

Try FitCD, its takes the headaches out of resizing.....

[OutSiderBR]

Thanks for the answers. I tried FitCD and use it because of overscan blanking, but I would like to know how to resize on my onw. TMPGEnc is ok, but I use low bitrates a lot, so I prefer CCE. But then, CCE does not do resizing, so I need to use Avisynth.

This thread explains exactly what I want. http://forum.doom9.org/showthread.php?s=44568e2cc0129696425e9620805556b4&threadid=18576

Now, I guess the answers are :

Film Resize to Borders
512x384 480x480 0,0,0,0
640x352 480x352 0,64,0,64
512x288 480x360 0,60,0,60

They are all in accordance with the given link by DJRump. The formula then is for NTSC:

Film new height = (Film Vertical * 480 * AR)/Film Horizontal

Add borders when needed. Should I count for pixel aspect ration (11/10 in NTSC) ? I think I do not need.

Anyways, thanks a lot all of you !
