As you know it from my comments in YT I used DaVinci Resolve before. I'm not fluent (just amator making family movies from holidays, family events etc.). In fact I don't use many of the efects but one I used before in DaVR was speeding or slowing clips in the smooth way. I can't figure out how to change speed of the part of the clip in smooth way in HitFilm. You have showed it in your tutorial for beginners how to change the speed of clip but I still don't know if it is possible to change speed in the smooth way using keyframes and curves like I did it in DaVR. Is it possible in HitFilm (I presume it is) ?
