I think so?

Assuming the timing were resets by the splitting tool, try this very elementary python script which will move all timestamps of sub2.sup to a value of your calculation (probably equal to duration of part1 + duration of subtitle-sliced sequence).

Usage:

Code:

python3 pgshift.py input.sup MS output.sup [-dts]

Where:
   MS is the shift delay in MILLISECONDS to add or subtract. It must be an integer.
   -dts, if provided, also shifts the decoding timestamps

I have seen a few streams which sets PTS = DTS at all time. In general you don't need to specify the optional -dts argument (and in fact it should not matter).

When done, concatenate the two files and hopefully the subtitles appears now properly.
