RealVideo 10 'Elysian'

[Manao]

Sagittaire : you're giving raw figures, you're picking out four examples, but in these four, two aren't relevant ( the first two of the last post ).

And I would bet that the other two can be explained if you look at the video itself, to see what happens. Because when there's an I frame that weights 45 Kb, then a B at 40 Kb, then a P at 10 Kb, there's something strange going on ( could it be a blended scene change ? )

Hi Karl
You state that turning off the Inloopfilter with RealVideo10 Elysian might break compatibility with old decoder dlls. I have tryed to create a incompatible RV40 video using jobfile with those two lines:
<inloopCutOffQuant type="uint">31</inloopCutOffQuant>
<inloopCutOffCompatible type="bool">false</inloopCutOffCompatible>
at a bitrate of 500kbits for a noisy 640 X 384 pixel TV capture of a music video. Afterwards i have viewed the resulting file with RealPlayer10 and RealPlayer9 an tryed to spot the difference/incompatibility, but i did not succeed. For what do i have to look out? Blocks? There where quite a lot with both RP 9 and 10 due to the small bitrate and the fog in the encoded scene. Or is it supposed to stutter?

The only incompatibility is that older decoders will always inloop deblock keyframes, no matter you set the encoder option to. This can result in a slight decoder mismatch compared to the encoder. There will be no stutter. You will have a very hard time finding any example where the problem is visible.
