Hi,

I love the KVCDx2 template, the quality is really good and though it's really small. But sometimes, when there is really a lot of motion in the scene, the video becomes jerky on a standalone philips DVD player, why??

Try increasing the minimum bitrate to 600 instead of the 300. That fixed the jerks for me.

It might be the VBV Buffer size. Due to the SVCD like bitrates it might help to go Settings->Video->VBV buffer size and set it either to 112 or to 0(automatic mode)

If that doesnt help see if your player supports firmware updates. At least my Yamakawa 715 wasnt able to play mpeg1 stuff with bitrates under 800 and over 2000 until I updated to the latest firmware(the openfirmware miniDVD one to be precise). Now it even correctly identifies anamorpic encoded stuff!

THANK YOU, ROOKIE!!!!! Changing the VBV buffer to 0 actually worked, woohoo!!

Glad to help.



As a rule(which Ashy over in the TMPGEnc help forum suggested) the maximum bitrate safely doable with an VCD standard VBV buffer is 1700-1800. Btw. Setting the buffer too high can also cause problems. Bugger is that htis only shows on standalone players.



Hopefully kwag will change that in the next kvcdx2 templates



Heres an very good explanation about the subject, unfortunately only in german language.

Go to http://216.239.35.120/translate_c?hl...33_vbv_mux.htm for that site in english.

remember that increasing the vbv work and sometime not work...its good to test it by increasing and decreasing..

for example my pioneer, cannot sync good if vbv is not 22.. the first thought would be to increase the vbv, wrong.. so sometime playing around with decreasing the vbv would be another option

Hi Rookie:

That's exactly why I had to increase the VBV buffer from the default value of 40 to 48. The templates MAX bit rate in the KVCDx2 is 2,300Kbps and a value of 40 causes problems on some DVD players if left at 40. A value of 48 takes care of that extra high bit rate above 1,850Kbps(+-) which is called the max bit rate in the constrained MPEG-1 specifications.

Does this mean that the yamakawa is running some sort of Unix OS inside Let me know, because I would like to test the Yamakawa DVD-218.

How come the VBV buffer is not set on 0 automatic then? doesn't that make sense?

That makes mpeg files that are not very compatible on many players.
