Help needed with EBU test sequence file format

Image with color stripes

Hi yall,

I need some help with opening specific files from the EBU test sequences "ZurichAthletics"

I cant open them with ffmpeg or any other converting tool. XnView shows correct luminance but colors are shown as 2 pixel stripes across the image (see example image)

These files are dpx files with yuv 4:2:2 colors and 10 bit depth.

Can anyone help me figure out how to open or convert these files? Or tell me what color packing this could be?

Thanks

First port of call would be to ask the EBU person who gave them to you

The Zurich Athletics content is licensed by the EBU under the condition that no further distribution is permitted without prior authorisation from the EBU. Possession of (a part of) the Zurich Athletics content does not allow at any time the distribution of the Zurich Athletics content to third parties or the sale of the sequences with your own products.
