I got this warning dialog box towards the end of Step 1 and Step 2 while saving my video in VirtualDub2.
Never had this before ever since I processed my videos before uploading to Dreamstime. I was stumped.
But this helps. I set the 'Level' parameter in the x264 configuration dialog box to 4.2 (from 4.1) and the warning never occurred again.
Problems with the frame rates per second (fps) of my video I think. I never had this problem with 30 fps video, but this popped up when my video was set at 60 fps.
