Xnview doesnt displays video clips colours

[AZK]

I have a strange problem from some days. Xnview doesn't displays colors in all movie clips. All pictures I see in colour, but video clips are black and white. What it could be

[xnview]

all movie files?

Yes, I think it is in all files types, but I verified it only with mp4, and wmv files. Standard photo files like jpg and all others are in color. This clips in other viewers are in color too, this problem is only in Xnview. I used this program from many years, and this is for the first time.

I've just checked that in avi files with lossless compression I see clips in color

[xnview]

could you send us a sample file?

I have the same problem: an MP4 short video is shown in only grayscale, with sound. XnView Classic V2.51.1 (6 Sep 2022). File is 35MB, too big to upload here. If you like I send you a Google Drive link to it by e-mail...
Strange: if I play it in XnView MP, then color is OK. Also, all other video players show color. I included MediaInfo information about the MP4.

Sorry, wrong location, I reported it again in Classic - Bug Reports...
