Green spots after uploading to YouTube or Facebook


I render Shotcut project and play my video correctly at VLC. However, when I upload it to Facebook and YouTube, video displays green spots on certain frames. See this sample:

How may I avoid this? This is my environment:

  • OS: Ubuntu Desktop 18.04
  • Shotcut: 19.06.15
  • Export preset: YouTube
  • Video mode: 1080p 30fps
  • Display method: OpenGL
  • Hardware encoder: Yes
  • Advanced: Set quality to 63% instead of 59%

I think it’s a YT or FB issue after post-processing, but I don’t know what could I do to avoid it.


It is probably due to your hardware encoder. I recommend you turn it off. It is possible a graphics driver upgrade will help but not sure.
