I have AVI files which I want to convert into MPEG files using TMPGEnc 4.0 XPress. The AVI files are 349mb-350mb each. Their dimension varies slightly but all are around the same size... some are 448x336 in dimension, some are 464x352, some are 416x320 etc. Their video bitrate vary slightly too but all are just under 1000kbps.

When I reach the format tab, I can select the video size but I only have 4 options:

- 720x576
- 704x576
- 352x576
- 352x288

I can select a size that's larger than the original but I would probably have pixelation since the video has been enlarged. I could select a size that's smaller than the original AVIs but then I would have reduced quality. I want to select a size that is around the same dimension of the original AVI files but none of the 4 options are suitable.

What do I do in this situation? Any advice?
