Step 2. Select MKV as Output Profile

Click Profile bar and move mouse cursor to Common Video category, here you can select MKV (codec: h.264) or HEVC MKV as the output profile.

Select MKV with H.264 or H.265 Codec

Tech details:

1. To get the best possible output quality and smallest file size, convert VOB to HEVC MKV. It has 50% smaller size at the same quality.
2. In addition to selecting HEVC MKV as the output format, flexible options are offered to further reduce the size of the encoded MP4 video. Click the Settings button beside the profile and enter into the parameter settings page. A slew of other variables such the video/audio codecs, pixel dimensions, frame rate, bit rate, audio sampel rate, etc. will help convert and compress a VOB file to a smaller MP4 file.

Recommended video quality/size settings for VOB to MKV conversion:

You're not suggested to adjust the frame rate and aspect ratio, if not necessary.
Lower the bitrate to a lower level. For example, adjusting the original Normal quality to bitrates of 1500-2000 is acceptable without noticeable pixellation.
Lower the resolution. Typical 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. You can go smaller, only at the cost of quality loss. 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.
