I render using the ‘Internet 1920×1080 – 30p’ setting.
After posting in this thread I saw that the embedded video looked OK but when I went to YouTube it was still there. I decided to download a different web browser to check if the problem still occurred and from what I saw it wasn’t on any of my videos. Could it be that the browser I was using was affecting the quality (I originally used Chrome but then switched it to Firefox to check)? Does the video look OK on your end or is there a flicker?
Thanks for the reply.
