x264 [warning]: --psnr used with psy on: results will be invalid!
x264 [warning]: --tune psnr should be used if attempting to benchmark psnr!
I put this one in discussions too. Not sure if it is a bug or commandline issue? I encountered it in Vidcoder but my encoding never crashed unlike some handbrake users.
x264 developers warn:
Can this warning be safely ignored ?
