Mini Converter UpDownCross HD converts Progressive only

PostTue Jun 12, 2018 2:27 pm

I'm testing the new Mini Converter UpDownCross HD (2018 version) and it seems that it doesn't convert correctly interlaced footage.

I'm trying to convert PAL to 1080i50.
I've connected a Sony IMX deck to UpDownCross SDI input and UpDownCross SDI output to computer for capture.

Output signal is detected as 1080i50, but it clearly looks like progressive.
So I've captured the same frame in PAL, then using UpDownCross and using Decklink Extreme 4K input conversion.

Original PAL frame:

UpDownCross Converter (1080i50):

DeckLink Extreme 4K (input SD to HD conversion enabled):

As you can see the UpDownCross frame is deinterlaced.

In addition the colors of the original frame and the one converted by Decklink are similar, while those of the UpDownCross are slightly different.

I did another test:

Input signal: 1080i50
Selected output format: 1080i50

Result: Progressive images in 1080i50 signal.

So UpDownCross ALWAYS deinterlace even if input and output format are the same.
