With respect to Field Order - NV/VirtualDub
I have found that if I start with a SD avi clip having Field Order = Upper, the processed clip has Field Order = Lower.
Whereas, when I repeated the test with a SD avi clip having Field Order = Lower, after processing it was still at Lower.
Am I to conclude that NV always wants to "see"" SD avi clips having Field Order = Lower?
FYI : Codec is Canopus HQ @ 720x576 50i or 720x480 59.94i, not DV.
Field Order changed during processing
Re: Field Order changed during processing
No, NV does not require any specific order and does not change the order when processing the video stream. Any change of the order that you observe is applied in another part of the decoding/rendering/encoding dataflow, not in/by NV.Andrisim wrote:Am I to conclude that NV always wants to "see"" SD avi clips having Field Order = Lower?

Just to make sure :
My editor is Canopus Edius 6 and the avi is exported as Canopus HQ codec 720x480 50i Upper Field. NV processes it in VirtualDub.
When I raised this matter on the Canopus Forum, the reply from a senior contributor was as follows:
Canopus HQ does not provide field order info to other programs, so other programs need to guess and Neat Video guesses wrong
so when you put the Neat video file back in EDIUS, it will flicker, so go to clip properties and change it to upper and it will be fine
Based on what you say, if NV is not doing it could it be VirtualDub?
