HitFilm handles t3i footage perfectly, but lags on footage from D3300
I recently got my hands on a Nikon D3300. I've shot some videos on it and now I tried to edit them in HitFilm. The problem is, HitFilm just starts lagging all crazy as soon as I import the files. And no, it's not because my PC is crap. I recorded some comparison footage on my mom's old t3i and with exactly the same settings, which it handles perfectly. If anybody has a similar problem or a possible fix, please let me know.
