AVI2DVD mode: Flickering result

[j_olson]

Since our cable provider often only have stereo sound I often get the better series with AC3 5.1 sound and convert them to DVD (NTSC) for watching. I have done this for several episodes without a problem, apart from one episode where the automatic field order didn't come out right so I had to rerun the conversion with bottom field first and it then was OK.

This time, I got the same flickering so I changed to Field B and rerun the conversion. Same result, so I changed to Field A - still same result! It doesn't look like it could be anything else but field order, but there are no more field orders to try... The source, while played on the computer, looks fine.

So I wonder:

* Is there a way to check the source for correct field order? I opened the file in VirtualDub but it looked OK regardless of if the Preview Filed Mode was set to Progressive, Field A or Field B... And you can't advance one field at a time, minimum a frame...

* Is there anything else that may have gone wrong? It sure looks exactly like a field order problem, but I have tried both possible settings now with the same result...

Its possible that its interlaced, have you tried the Telecide option. If its an MPEG2 file, then check it with Bitrate Viewer (www.tecoltd.com)

[j_olson]

I haven't tried that option, will do that, the source file is an XviD file (run through VirtualDubMod as suggested in the sticky).

[j_olson]

Telecide seems to be PAL only, maybe Smartdeinterlace..?

Edit: Smartdeinterlace didn't work a bit better, I'm a bit at loss what to try...

[j_olson]

I rechecked for Packed Bits, and while it wasn't that MPEGModifier anyway showed the source to be non-interlaced...

For interlaced sources you should see combing...

Another option is decomb's FieldDeinterlace(full=false)

[j_olson]

Well, but it isn't interlaced... I think I will try to get another source file, while an interesting problem it's not worth putting so much work into...
