Creating a VCD without "blowing up" the image?

[djmn]

I'm relatively new to this and had a question about image quality and sixe. I did a "test" VCD using Cleaner 5 and Toast Titanium. Everything worked fine, but I have one question/complaint: the original mpeg I have is 160x112 pixels and to create the VCD Cleaner 5 creates a mpeg1 stream thats 320x240, thereby expanding or "blowing up" the original movie to fill this dimension. Obviously there is considerable loss in quality doing this.
Is there a way to retain the original size and create a black border or something around it to make up the 320x240. In essence "reverse cropping" or as it's called in Photoshop, increaseing the canvas size?

In theory, TMPGenc MIGHT be able to do this, if you specify that the ratio not be changed, and add margins. Hmmm Bears investigation tho.

I don't know if TMPGEnc can natively do this, but VirtualDub definitely can.

Load up your original MPEG with TMPGEnc and add the relevant filters (resize with letterboxing/add borders option). Then frameserve to your favourite MPEG encoder.

Regards.

Am I wrong, or would the conversion to vcd make the resulting image "soft" or less quality than the original seeing the original is smaller. If not, then there is no reason for me to try and create this border. Does the vcd encoding take this into account and interpolate it in some sort?
Thanks

A VCD is 352x240 so the video you are trying to use is too small to get a good encode unless you can come up with a way to do black borders. The software being sugested is all PC stuff. Good luck.

TMPGenc can do this. Basically when you make an x(S)VCD you have two choices when it comes to resolution.

1) The MPEG takes up the full TV screen.
2) Your MPEG is displayed within the 720x480 TV screen (sort of like playing it on your computer).

Is it possible to do this without running Virtual PC? I don't have that, and I just want to encode some vcds!! I have two files that are 320 x 192, and if I could just artificially add the extra 48 pixels, using Toast 5 Titanium, I'd be set. Is there any way?
