This is really interesting. I just tried this, taking the output of one computer and capturing on another... and not only did I get a bad image quality in Isadora, I was also seeing bad image quality in the Blackmagic Media Express Capture Window. Have you tried capturing from there to see what that looks like? I note the other things you tried...

Hi @dusx, changing to 60i as per your suggestion did not show any visible change.

Hi @mark_m, preferences are:

Video Image processing default resolution is the same as the source. All the show runs at 1920x1080 from source to projectors. I tried playing with  frame rates at source, Isadora preferences and output projectors without any visible change. Videos and pictures launched from within Isadora look OK, problem only shows on captured video. I will post computer specs when able, just in case somebody spots anything significant.

Many thanks for the assistance.

Did you ever figure this out @Aolis ? I am looking for something similar! 

@nic - all sorted now with a good Cam Link converter, I had a rubbish capture card. Don't trust anything under £50 to produce true 4k output!

@dusx Neither do I, but I use a blackmagic quadlink HDMI capture card inside a sonnet cabinet via usb-c on an M1 on a mac.

The msg:string={00-FF} parsing pattern is nearly always my starting point when I am trying to receive Serial text data.

This parsing pattern will output a string made up of any of the Hex values 00 through FF (all of them). This works often to get you started since you can see the full message received eaisly.

You will want to watch your incoming serial data in the Monitor window to see how this output matches with the input.

@dusx

thanks for your answer, but i can't make any sentence out of these pages.

I'm missing example sentences. Like i use now. But i can't make other sentences out of these pages.

For me are these pages explaination of the elements in the sentences.

How should i extract these sentences:

(- msg:string={00-FF}

-value1 : string =  EOL)

for the help-pages?

@patufet

Hmm, I haven't had nor seen this issue with BlackMagic capture before. I wonder if using 60i is any better for you?

"3840x2160 (scaled from 1920 x1080)". Does this mean that my card only sends HD

 Yes, this indicates that Isadora sees this as a HD source and is allowing upscaling to 4k. Does your card have any configuration tools?
