HitFilm Express slow motion problem
First - sorry for my English...
So, I have a problem. I have few video clips from my go pro 5. I recorded in 60 FPS. I making new video and drop my clips on timline. I making project in 30 fps 1080p. When I would make slow motion I have bad frame rate its poor, so poor... When I change Clips proporties from 60 fps to 30 fps and put on timline its okey.
I used all effect for speed, but doesnt work... I dont know where is the problem. I made speed/duration, but to not working = tears frame.
Here is screen: https://ibb.co/0D0n6F4
P.S its okey, when I made only slow motion to one clip, what I must can, when I need make speed ramping?
For example 5 sec slow 10 sec normal?
Thanks for help!
