I often seem to hit a problem of poor quality renders from HitFilm. For example, if I add a vignette effect to a clip and export my video, I get poor colour or tone gradients from dark to light. It doesn't seem to happen in Vegas Movie Studio.
I tried higher render settings, which helps a bit, but generally the renders just don't look as good as from Vegas. Currently, I'm having to render in lossless quality from HitFilm, import it into Vegas, then render to a more standard, lossy format in order to get a reasonable result. Anyone else notice this or have this issue? Example attached.
