Yes, I used two avs inputs into both VQMT and ffmpeg. What did you use?

Same with VQMT - it can't be exactly the same clip because I had 5002 frames vs. your 5000.

I had adjusted the avs script to 5002 frames to match the sample I sent you (which was cut on the MPEG-2 GOP), but Resolve apparently didn't notice that I lengthened the intra .h264 input file and only output 5000 frames, so I just kept the comparison to 5000 frames.
However, I just went back and redid the whole thing and made sure I got 5002 frames this time.
