mpeg2 Resize ?

[madmuppet]

Is it posiible to enlarge an mpeg2 SVCD.
I have a few SVCD's that I did not convert that only fill about a 1/4 of my 32" widescreen tv.
I can zoom on tv but even that only takes it to about 3/5 of the screensize.
Is there a way that I can reconvert the SVCD and increase the screen size.
I dont have the original DVD so I cant convert it from scratch again.
I know you will think I am barking mad.(your probably right):D

If possible or there is some thread kicking about I cant find by searching I would appreciate the help

I know if this is possible I will lose some quality but I only want to resize to 3/4 screen so my tv can zoom to full.
If anyone knows how to do this please let me know.

Hi,

i dont know if it realy works, why i never had such a problem but maybe you will try it:

load your *.mpg in dvd2avi an create a projekt file. load this in FitCD and create a *.avs. (you know how to handle with FitCD?)

look at the *.avs resize values and put them to the right dimensons for you (just keep the ratio / value X * 0,75 / value Y * 0,75).

form now on i think you know how to fix the rest.

maybe the safe way with VFAPI
or the fast way direkt load in CCE

hope, i was able to help.

bye mark

Hi m8 I have made a project file and I have downloaded FITCD but I dont know how to use this with the file.
Could you explain this to me.
Thanks

hi,

sorry i know only a german guide with pictures, but there is also a readme form shh in english, wich is pretty good. try to work with it. if you fail, i can give you a short discribtion:

first of all you have to browse and implement the mpeg2enc.dll (right side)

middle/left side called mpeg resizing:
load your source (dvd2avi projekt)
if you have done this, fitcd will give you the time and frames 25 pal for example.
as you can see on top/left side. if you would like to have 2 CDs set the half time ;-).

top left/stream
here you can set your audio kbps

middle left called mpeg resizing:
now you have to set the coded film pixel (you can get them with dvd2avi by cropping. you just have to cropp the black or grey fields away. in the shown statistics you can read the coded film pixel. now leave dvd2avi and be sure, that cropping/resizing is not longer marked. this is a must !!!)

you have to choose your output (svcd) and the 2 blocks overscann for the televison optimizing.

the multiplexing should be done by bbMPEG, and the authoring by vcdimager.

if you have made your settings, read the max / min / avg bitrate, maybe you will need them.

if you save your settings the avs will be created. now you kan edit it again.

i hope i've nothing forgotten.

here is a link, where you can see some nice pics of the right settings.

and for the last time please excuse my english.

Sorry m8 I am still lost.
I wish it was as simple as just using DVD2SVCD :)
Here is what I have done so far.
I opened DVD2AVI then opened FILE and selected my MPEG2 file.
I then selected save project.
After about 4 mins I had 2 files
1)movie MPA T01 Delay 0ms.mpa(72,651kb)
2)movie.d2v(173kb)
I then opened up Fitcd v1.0.3 and selected the mpeg2enc.dll (right side)
Then I opened the source folder and selected the movie.d2v file.
The time of film is 44mins 17 secs at 25 FPS.
I set the audio at 224 as I always do.
I dont know what to do with the resize
It shows
Source 480x576 SVCD PAL
Coded Film Pixel 480x576 left border 0,Top border 0
Crop 480x576 NO CROPPING
Round To 2,2
Resize 448x542 =5712 Blocks=394bps/block= 1:48.7 compression=57.59%=1.3547
Optimized for CCE . 2 Blocks TV Overscan
Destination Size 480x576 SVCD Anamorphic & Format Conversion BLANK.

if you save your settings the avs will be created. now you kan edit it again.

If I leave all these setting and press save on disc at bottom right I know have a file called movie.AVS (1kb)

Is this right so far or should I have cropped the borders off somewhere.
Why is file so small and what do I do with the 1kb movie.avs file.
How do I edit it?

I have read the guide by shh but still dont know.
Thanks

Hi madmuppet,

you forgotten to cropp in dvd2avi to get the coded film pixel.

but let us look at the resize:

source is ok !
coded film pixel / uh, bad ;)
you have to open your mpg in dvd2avi, now you go to video - > clip & resize - > check the mark top/right for cropping in dvd2avi. you can cropp by moving the sliders left/right/top/bottom. now you get your coded film pixel if you look for width and height. note them! now you have to uncheck the cropping!!!!

you can fill the coded film pixel in fit cd.
btw, i would let them as they are, dont set them to 75%. your tv will smooth your picture if you zoom, as you will do with an accurate resizing in avisynth (i guess).

set cropp to accurate

round to 2 / 2 is ok

let the rest as you see / the resize will be other values after you fill the coded film pixel, leave them alone too.

after saving, you will get your *.avs.

start your cce add the *.avs set your min / max / avg bitarte, as you can see top/left in fitcd bevore saving. uncheck audio (this is realy needed, cause cce will give you maybe problems or bad audio. if you work with AMD CPU edit in the *.avs the crashfix for athlons by inserting
resampleaudio(44100)
you have to do this even if you unchecked audio. dont ask why just do it, if you work with AMD CPU.

just demux your audiostream, take your new *.mpv, mux with bbMPEG.

hi madmuppet,

after looking formula 1, i'am realy relaxed, and full with ideas for your problem.

there is another realy easy way for resizing. but you will loose a little bit quality.

1.) make the cropping as i told you. let the field in clipp & resize checked.
2.) save your projekt.
3.) take the vfapi reader and build a pseudo avi. just by loading your *.d2v and convert.
4.) load your pseudo avi in CCE or bye using a littel lower avg bitrate than fitcd told you before.
5.) encode
6.) mux with bbMPEG

I think that will be the easiest way for you. :D

bye hammer
