What's up with this capture? (Blending??)

[kiwiusa]

I have just captured an old PAL VHS tape of a TV show I recorded back in the 80's.

It seems to be horribly blended but still also has quite a bit of combing.

I've attached a frame and a small section of unprocessed m2v can be downloaded here.

I'm curious as to what is causing this and also any advice on correcting it.

Thanks in advance,

Alan

I don't see anything wrong with it except for the interlacing (and the VHS artifacts, or course)...
Any decent deinterlacer/bobber like Yadif(+nnedi) should get rid of the combing.

If you remaster it for DVD, bob it to 50p, then apply your filters and then reinterlace it.

You need a deinterlacer. Try yadif.

Or, for super duper quality, try mcbob() 0.3u

It seems to be horribly blended but still also has quite a bit of combing.
Create the following script:

MPEG2Source("F:\Plugins4\Sample.d2v") # from DGIndex
SeparateFields()

You will see that it doesn't contain blending and that it is progressive. It is phase shifted material (that's why it looks like your screenshot contains blends; because you didn't correct it). It can be corrected by using:

MPEG2Source("F:\Plugins4\Sample.d2v")
#SeparateFields()
Telecide(order=1) # order arg is removed in latest DGDecode

Thanks all for the great responses - much appreciated.
