Aspect ratio problem

Hi, folks I use a procedure very similar to gerty67 but based on the mean of Resolution (R = X/Y), Display Aspect Ratio (DAR) and Pixel Aspect Ratio (PAR). In a given conversion the product of R x DAR x PAR should be nearly constant so: [R x DAR x PAR]input = [R x DAR x PAR]output PC monitor VGA has DAR = 1 and PAR = 1 Fullscreen TV has DAR = 4/3 and Digital Widescrren TV has DAR = 16/9 In case of PAL TV PAR = 54/59 and for NTSC TV, PAR = 11/10. Accordingly if our input is a Div X video of resolution X = 512 and Y = 384 and our output is a SVCD video for a digital TV PAL, then (512/384) x 1 x 1 = (X/Y) x 54/59 X 16/9 The output resolution is X/Y = 0.819 Thus, if we keep X = 480 (the standard width of PAL SVCD), then Y = 586 > 576. For this reason Y = 576 is kept instead, which gives X = 472 (approx.). The borders to be added at the edges are (480-472)/2 = about 4 pixels. If our case is a digital NTSC TV then (512/384) x 1 x 1 = (X/Y) x 11/10 x 16/9 X/Y = 0.682 Taking Y = 480 we obtain X = 328 (rounded to a even number). In that case the borders to be added are (480-328)/2 = 76. I hope this could help Bye

IMHO, the problem source is that the horizontal dimension cannot be resized to 480. Try the program in order to establish the suitable avisynth script. I hope this may solve your problem Bye

All tv's are going to crop some of the image when it displayed, tyr reducing the output size by 16 or 32 pixels on all four sides and then add either 16 or 32 pixels to the borders of all sides. This will reduce the size of the video. As for the perm subs you need to adjust the hiehgt of where the sub is inserted or add the subs before you resize. I usually add borders after the resize.
