Hitfilm Express and Flowframes
Hi!
I've been doing a slow motion test with Flowframes and Hitfilm.
Flowframes is a nice piece of free software that increases the frame rate of your footage, giving an opportunity to make good looking smooth slow motions (when the interpolated footage is imported back to Hitfilm and slowed down of course).
However, I noticed something strange; if I have an interpolated clip of let's say 60 fps frame rate it runs smoothly only if I export the thing with the same frame rate. Trying to export it for example in 30 fps or 24 fps makes it a bit choppy :(
here are the video tests, is it only my eyes? The first video is 30 frames per second and the last one is 60.
Anyone have any idea how to make the 30fps export as smooth as the one that's 60 fps?
In my case I would like to export most videos in 24 fps but with that choppiness I'm going to have to figure out how to do the slow motion some other way :S

Ok nobody replied yet but I found out that the problem could be my phone's camera, it shoots probably at a variable frame rate when it should be constant. This could be the root of the problem.

Yep, most probably the case. Nearly all consumer devices shoot at VFR and the editor needs CFR to be accurate.

@Jussi @Stargazer54 EVERY phone/phone camera app shoots VFR. Period.
Even the iPhone 13 Pro's much vaunted ProRes is VFR.
The most significant thing phone makers/app programmers could do would be to get a freaking phone to actually shoot CFR
