THe real Resulution of VHS is 576 columns (vert. res) and about 240 lines per column (hor. res).
But lines are NOT equal to pixels, because VHS is an analogue medium.

And because of the digital sampling, every line has to be digitized with 2 pixels. So your minimum capture resolution for VHS will be 480x576.

Making 352x288, you'll loose MORE than the half of your information provided by the VHS-Tape!

But you can choose 352x576 for encoding to MPEG-2, this res is called Half-D1 and is part of the DVD-Standard.

Another Thing: The resolution is not proportional to the resuling Filesize! The only thing, that influences the Filesize is the Bitrate!
And the bitrate can easily be changed in TMPGenc.
