Interlaced Progressive video?

[eng3]

I recorded some video using my MyHD.
It was from FOX 480p.
I thought the p meant progressive, non-interlaced, but the video looks interlaced. There are many jagged edges, though fielddeinterlace does nothing.

any suggestions on what might be going on?

Much of Fox 480p is just interlaced material that has gone through their own deinterlacer, sometimes with not very good results.

I don't belive they use any 480p @ 60 (or higher) cameras at all but at least some film source really is a decent 480p.

ah. hmm, so should I still try deinterlacing?
FieldDeinterlace didnt make any difference.

I dont know much about Fox 480p streams since I just don't stream that station, but some German stations have streams similar to the ones You describe. The flag supposes the stream to be progressive, but when You have a look at it You find Yourself in interlace wonderland. Since I don't reencode that stuff at all this will never affect me in any way. If I had to deal with this stuff because I want to reencode or such, I would use kernel deinterlacing via avisynth. You could also try to do some frame-based deinterlacing instead of field-based... or both. These would just be my ideas about it.

nah, you're getting a progressive stream, its just there are some interlace artifacts left by their encoder. Local fox stations have been frustrating a lot of people. I have a friend who gets a 1080i on his fox which is usually film transferred to 480p then converted to 1080i. he's concluded he can't really get a clean xvid made off that. Best thing is to just wait until fox goes to true hdtv next fall. :)

sounds like the compulsary HD broadcasts here are a good thing then, altho some of the programs that have been chosen to be broadcast in HD are a bit of a worry...
