Now I have a problem, ever since I updated my hitfilm express 15 to the latest version, I find it hell when i try to embed a composite shot into my editing timeline as well as when i use a text template into the editing timeline. When i play back the video, it sometimes keeps flashing up and down. When i try to export, It exports but gets stuck with one frame, especially where the composite shot is or text template. Before, it never used to happen but the hitfilm 15 latest update messed everything. I'm Using a laptop with 8Gb Ram and 256SSD with Intel HD Graphics 520. Its a core i5 6th Generation. Hp EliteBook 840 G3. please help.
