Hello!!! Please answer!!! :(

Hello, I’m a beginner in 3d unreal engine, now I’m working on my second project, but I have a problem with dilatation time. I made 2 topics, 1 when I started with another problem, it didn’t answer, the second one I wrote a few days ago, neither an answer and I bet it’s a simple thing that we beginners don’t know…

I searched everywhere but I can’t find a concrete answer .please, I’ve been trying to solve this problem for 2 days. I use time dilation in the sequencer, everything works flawlessly here. But when the clip finishes playing, it’s totally different, even though I set {frame_rate_rel}, thanks.Please help
the clip is much longer compared to the sequencer and is not assembled with the melody and words as it is in the sequencer…

Please answer so that I can be clarified…Or how could I give velocity to my video montage, I want 3d, not in after effect or etc…In general, I make CSGO montages, I need velocity in the sequencer…
