As for DAT encoded mostly by MPEG-1 or MPEG-2, it's included in VLC hardware decoding codec.

To use VLC to free transcode DAT to MP4 (any size), follow the below instructions:

Optional: enable hardware decoding on VLC.

Before you go, tap Preferences at the top menu of VLC > Input/Codecs > move to "hardware-accelerated decoding" and change Disable to DXVA 2.0 > tap "Save" button. Then go back to the main interface.

Step 1: Open the convert window.

You can click another 3 buttons at your right hand to choose video/audio codec (incl. H.265, VP8, MPEG4, Theora, etc.), adjust the bitrate, quality, frame rate, add filters, and more.

Step 4: Start to hardware decode DAT to MP4!

Hit Start and VLC's conversion engine will go into action to convert a DAT to MP4 format. Since VLC only features hardware decoding, no hardware encoding, the encoding part will still rely on software encoding, slightly more heavy on CPU usage (compared with MacX's hardware encoding) and much slower on conversion speed. Certainly, maybe hardware encoding tech will come to VLC in the near future. Expect!
