I just discovered HitFilm a few days ago, while searching for a new video editor and, I have to say, I really like it .
This is the first project that I have done using HitFilm. I did the compositing in Nuke and used HitFilm to add the audio, the two cartoon windows and do the final export.
The shot is a live-action re-creation of the lego lava from the video game South Park : The Fractured But Whole. It's best viewed in HD.
Let me know what you think.
