Manihi : too much k frames...

[jonjon51]

hi @all,

I've done some tests to compare DivX Pro 5.0.5, Manihi, and Kauehi (not Tahanea, because I think it don't have so much improvments compared to the new one called Manihi ;) ). to my mind, the quality is very good, in spite speed :( ).

here is a screenshot of a excel file (ok, I'm too lazy to recopy it :D ):

my problem is that there is too much K frames inserted, compared to the old DivX Pro 5.0.5. the scene change threshold is set to 50% and max kframe interval to 250, for all codecs... if I set to 100%, nothing is better :confused:

the clip contains 2443 frames, and the AVISynth script is very simple (just MPEGDecoder, Crop, and SimpleResize).

does anyone have the same results :confused: it's really really strange...

(and excuse me for my bad english :D )

Press "Restore default settings" in the codec window...it should go really better!

I tested, but that does not change anything. I wonder whether that could cause problem, for reading for example, if you have 30 to 50 consecutive I frames... and on standalone player (I have a KiSS DP-500):confused:

moreover, I tested in fastest mode for motion estimation, and there, I obtain 10 K frames, but a loss of compressibility of 47,27% :(

This behaviour is normal for the new performance/quality modes.
