Maybe this point is worth some details: h264 permits use the middle B-slice as reference, making the reference anchors not so far from the remaining inbetween b-slices (non-refs). So, you're back to deciding PbBbP over PbPbP for the refs, which is quite similar to the PBP vs. PPP decision, as far as refs placement is concerned. Well, this is quite an uncharted (and slippery) land, but some are advocating use of GOPs as big as 32 (!):

What is the suggested (default) gop size for h264 anyway? I was under the impression something like 250 was sort of optimal for (old style) mpeg4. -------------- next part -------------- A non-text attachment was scrubbed...
