I have encountered strange behaviours in hitfilm that were not taking place in older versions and I think they are some bugs. But please, feel free to correct me if I´m wrong.
1: When doing some VFX work in a comp. , effects (Like heat distorsion), are afecting the X and Y "Axis" in hitfilm. This is cousing an inestable experience for a user. Image:
2: Keyframes are not updating in real time during playback.
