2-sec CBR fixed Closed GOP is used a lot out there. Preventing keyframe strobing with that is an interesting challenge.

When I do encoder comparisons I normally do a 1-pass 2-sec fixed closed GOP CBR and a 2-pass max 5 sec GOP with VBR (with VBV limitations). Those two captures two good real world scenarios but exercising quite different encoder features.

I care about "without VBV" tests only slightly more than I care about PSNR plots. My customers will never see either .
