I'll provide a ticket if needed. I tried to use a Prores file from the Rody Polis Action VFX collection and Hitfilm PRO 6 immediately crashes if I try to use the trimmer. If I just put the file on the timeline, part of the video is displayed on the top and the rest is displayed on the bottom. None of these issues happen with HitFilm Pro 2017.
As an example use Fireball_0002_2K.mov
I think I sent at least 3 crash reports this afternoon.
In addition, I get an immediate crash if I try to use a ProRes file on the editor timeline.
