    virtualdub can do it but it is not adviced as taking low reselution video and resizing it to higher reselution = lower quality. Your better off keeping it 160x120 unless the change is required for somehting other then casueal viewing. Even then leting a media player stretch the video clip will look beter then a permanent resize.

      Actually I have many file. So I want to change it to mpeg, then make VCD. I've already know how to join them together. But the problem is the resolution too small. So how I want to increase the resolution of the file without reduce the quality.

        "So how I want to increase the resolution of the file without reduce the quality."

        If you go any higher than the original 160x120 framerate, the quality of the video will suffer.

            There is NO software I know of that will improve–or keep the same–the video quality of the "Original". If you use TMPGEnc for example, to change the resolution to VCD (352x240 for NTSC, 352x288 for PAL), I can't see how you can expect the visual quality to be the same as your original AVI at 160x120. You can certainly encode the AVI to mpeg, but don't expect miraculous results.

              Do you have the original tape? Why is the resolution so ridiculously low? I don't think there is any video camera that records with such abysmal quality. If you don't have the camera tape and you just have a copy of the original file that has been transcoded to this low resolution, like the other guys said, you're out of luck

                You need a better capture card that will allow you to capture at a higher resolution. If this is not possible, you can of course always resize your videos to standard VCD resolution ( 352 x 240 NTSC or 352 x 288 PAL ), but as the other guys are telling you, the quality maybe wont be very good. If you do, make sure to use a sharp resizing filter like precise bicubic 1.0 or Lanzos or the like
