Willing to bet they Astra'd and had an engine fail just after liftoff. Dude on the console probably wasn't watching the clock and called prop about before he realized it was already in the air.

it was in lower altitude than designed due to under performance, so maybe the modes isn't an issue

There were huge clouds of sparks coming off the first stage engines at the end. I'm willing to bet they were running turbopump-rich on at least one engine.

Part 2

Also no I don't know why webm for retards is making these so far below the 3MB limit that I set for it. I have an old ffmpeg build that I can manually make webms in but then I have to type everything out and it takes a while

hard to tell. it kinda looks like it changes direction a bit before exploding. also some rockets FTS systems just cut the engines, others explode the fuel tanks. i don't know what their FTS does

It starts around T+0:50 and becomes more obvious at T+1:25 in the video below. Its even apparent in the interior shot of the 2nd stage engine.

definitely FTS, you can see a small charge go off to split the first stage tanks and a larger charge for the upper stage
