Tvheadend

Hi!

I'm using the Version 4.1-210 of TVHeadEnd.
On Version 3.9 i had an script for file renaming.

Now I want to use the Format string in the recording Profile section, because all of my recordings are marked as "failed", because of "file missing"...

I'm using this Format:
%F %R $c $t - $s.$x

Is it possible to limit the chars in title or subtitle?
Some recordings have an endless description in subtitle I want to limit this to ~30 chars?

regards
