Hey, I've seen this a lot across the board and thought I'd share the magic that makes submissions show up correctly.

In the Video link segment you can have up to 5 videos show up with their embeds. Same goes for the Description

Video link: In this you need to separate the links with a double space, otherwise every 2nd link will only show up as the link instead of the embed you want.

Description: Here you only need to put a link per line. Embeds here won't look as pretty as they do in the Video link segment but its good enough if you ran out of space because too many videos or its a different version of the same thing (say YouTube video for Video link, Twitch VOD for Description).

Breaking the limit of 5 videos per section: As far as I can tell you can actually get around that limit with using videos from different sites, I haven't done any testing on that but this run here shows what I mean, if you really have that many segments then this might be the way to go for you: https://www.speedrun.com/multimario/run/ydgo3eqy

Hope this helps! - Blood
