So what we've learnt is:
- For an exact comparison we should match average bitrate closely. So for instance match 3.100a2 -V2 against 3.99.5 -V1.85. - Especially at high quality levels deviations in average bitrate are of minor concern to many users of these levels. Quality is what counts in the first place to them. But that's no contradiction. Just let's search first for an average bitrate comparative setting before comparing.

Just let's search first for an average bitrate comparative setting before comparing. For what its worth, I'm perfectly happy if V2 leads to higher bitrates on difficult to encode samples if it means fewer artifacts. I think the main concern is that tweaks might boost the bitrate on samples that are already transparent, which would be a regression. I would say we should run a set of normal (that is, not known problem samples) and see if bitrates changes on those too. |
