When adding 50fps HEVC files to a project of about 7:30 length, and rendering that project, Vegas regularly crashes after approx. 70% render progress. Quality setting=Optimal.

There is no problem with projects <5min, and no problem as long as no HEVC media is present.

This crash is reproducable 100% on my system, also with new footage and new project file.

Version is Vegas Pro 14 B161. Windows 10.

Does anyone have any idea, how to render projects with HEVC media?
