AV2HDR results in increased file sizes

Hi does anyone know why putting a 5GB VOB through AV2HDR results in a 5.5GB .TS file. Does AV2HDR perform any re/encoding of the original file? It seems odd that it should increase by 500MB if it isn't.

The TS format is based on fixed size 192 byte packets which includes an 8 byte header. Roughly estimating, a 5GiB file broken up into 184 byte chunks gives 29177766 chunks so adds an overhead of ~222MiB. Additionally there are some other non-AV frames that need to be added along the way so that the Humax can properly understand the file (Programme allocation table for example).
