Here is an alternative solution that starts with {}, an empty object.
Instead of ending subsequent item with a comma, start with a comma. By
the way, preexecution can also be replace with rendertag to make run faster.
{"Image": [{}<!IoRangeList><!IoRangeRedDotMode><!--<%lst_plSW%>--><
!/IoRangeRedDotMode><!IoRangePreExecute><% if "<%std_url%>" <> "" then %>
,{ "YouTube-Titel": "<%hdl_ueberschrift%>",
"Hersteller": "<%!! Context:Pages.GetPage(Guid:<%inf_pageGuid%
>).MainLink.OwnerPage.Headline !!%>",
"Kategorie": "<%ol_videoTyp%>",
"URL": "<%std_url%>"
} <% end if %><!/IoRangePreExecute><!/IoRangeList>
]}
