I have a problem after this build 201 update. After rendering there seems to be dublicated frames in video. I have tried at least Sony XAVCS and Prores (29.97p). By checking rendered video frame by frame the issue can be seen.
Maybe it is my computer or videofiles, but Vegas Pro 14 worked before update. My GPU is old GTX460. My camera is Samsung NX1 (HEVC 4k files).
EDIT: I checked again with EOS M files and they seems to render correctly. But my HEVC 4k files don't.
I just render a clip and it really seems that my HEVC 4k files are not supported now correctly. Every, lets say 8-10 frame is a dublicate as far as I can understand because the video is not moving then. When I render I just choose the output format (e.g. Sony XAVCS or Prores (29.97p).). All else default.
Does this one similar to yours?
I am downloading one of them and test it. Should be similar file.
