How?
Converting 4:2:0 to 4:4:4 works fine here.

-> Read the sticky, provide a debug output and give details about how it fails.
Also if you replaced any binaries in Hybrid or your system is overclocked tell me.

Hi Selur, sorry for delay in response (very busy in my work) but I found where the problem is.



Whenever I convert from i420 to i444 directly,no filters, this works.



But if I use the FPS adjust> InterFrame option, double frame rate and select to convert i420 to i444, always error.

Also try the Avisynth Preview.
Wild guess is that the Avisynth Interframe filter has a problem.
(You can also try the Interframe Vapoursynth filter.)

Hi Selur,

Interframe Vapoursynth works awesome. Convert to i444 + Double frame rate.

Thanks for tip.
