frame size conversion

[jledhead]

I have been playing with various software to convert to vcd qualtiy mpg's and recenlty been having trouble with the frame size conversion. I have tried using virtual dub and adding a resize filter, but it does not give me the desired output. I am trying to convert 672X240 to 352X240 and having some output problems. it does not convert the frame size to the same image size. I am trying to use CCE and it does not resize. any help or advice would be appreciated.

and for vcd and svcd is the frame size that important and does it have to be the exact size or can I just leave the frame size to 672X240 and encode and burn and then play on my dvd player?????

I encode 45 minute Enterprise episodes at 640x480 VCD's at 1700bitrate and they play fine on my Panasonic RV31

A VCD must be 352x240 and an SVCD 480x480 or they are NOT VCDs or SVCD's. Frame size is ABSOLUTELY DICTATED by the format. Your question is really, I think, do I have to make a VCD or SVCD? That is dependent on your desired playback methodology.
A VCD will have the best compatibility with DVD players, SVCD less so but similar. as soon as you deviate from those standards, its a crap shoot whether it will work on various players.
Having said that, you are free to make anything you want, whether it works on a given player or not.
For resizing w/CCE, I use AVISYNTH bicubic or bilinear resize and frameserve. You might try adding borders to bring size to standard 480 or 720.

AVISYNTH?? is that a different proggie or a process?? I will search. and can you take an avi and run it thru avisynth and resize and frame serve to CCE??? because when I framesever with Virtual Dub it messes up the picture and doesn't keep the full screen image. that is my main concern is keeping the full screen aspect, instead when I resize with Virtual Dub and frameserve to CCE the picture is fullscreen and not widescreen.

Avisynth is a video editing tool and frameserver similar to VirtualDub but without a GUI. You can resize with VD easily. If it does not work for you I suggest to read the guide again.

If you have an odd source resolution I suggest to calculate with FitCD.
