Sony EX1 HD Footage -> Chroma Errors

[koopa]

Hey guys,

I have a nice new/shiny Sony EX1 camera, takes nice looking footage... or at least it is meant to. It is not quite as good at still frames as I had hoped.

One of the biggest problems is that if you deinterlace the footage to 50fps, the colour seems to be out of time/sequence with the Luma.

When I try to use NNEDI2(3) on the footage, the Luma ends up progressing correctly, but the chroma jumps ahead and behind the motion. When I use NNEDI2(2), the chroma progresses smoothly, but the luma jumps back and forth. My attempt to make a script to combat the error has failed:

avisource("sample2.avi").converttoyv12()
source=last.NNEDI2(3)
NNEDI2(2)
Mergeluma(source, 1)

Could you please take a look at the sample and tell me:
1) How to fix the script to make a stop-gap fix.
2) What the heck is going wrong?

Especially if you have experience with XDcams, is this a bug in the camera? I have tried many different MPEG2 decoders (unless I'm being fooled), and this only occurs with footage from the EX1.

Cheers guys!

sometimes ago i had similar issue with DV and it was wrong DV codec.

avisource("sample2.avi").converttoyv12()
This needs to be converttoyv12(interlaced=true).
Unless your clip is already being decoded as YV12, in which case you can eliminate it altogether.
What format does it say if you just do:
avisource("sample2.avi")

converttoyv12(interlaced=true) completely fixed it, thanks Gavino!
