Tech details for VOB to MP4 conversion with best quality-size balance:

1. To get the best possible output quality and smallest file size, convert DVD to HEVC MP4. It has 50% smaller size at the same quality. But please make sure that your device or media player does support HEVC for playback.
2. The default setting works well. Of course, if you want to customize video and audio encoding settings, just click the Settings button to customize these settings.

Recommended settings:

1. You're not suggested to adjust the frame rate and aspect ratio, if not necessary.
2. Use the codec H.264 or H.265 and lower the bitrate to a lower level. For example, adjusting the original Normal quality to bitrates of around 1800-2000 is acceptable without noticeable pixellation.
3. Lower the resolution. DVD VOB videos are 720×480 (NTSC) and 720×540 (PAL). Adjust the resolution to 640×480 won't make any quality difference.

Please note: Adjusting these variables have some effect on the re-encoded video quality. Remember the file size and video quality is based more on bitrate than resolution which means bitrate higher results in big file size, and lower visible quality loss.
