terrible quality of live input with blackmagic

mark_m

Agreed, the quality doesn't look good.

What camera are you using? What's the resolution?

And can you post a screenshot of your live capture settings, like this?

dbini

like Mark says - check the settings of your Live Capture, but also - check the setup of your default resolution (in preferences) and output resolution (in stage setup and Izzymap) - if everything matches, then it should look great. it will be interesting to find out what's going wrong here...

Also, in Preferences have a look here and try changing the default resolution to whatever you are outputting, or to the resolution of the image:

The picture is straight from another mac (no camera involved).

As i am troubleshooting it's a straight patch (no effects, no nothing). You can see in the izzymap window it's already terrible...

On mac it's the same...

Please help...

Sorry, more screenshots

@zedociel

In Isadora Preferences > Video > OpenGL try enabling Full Frame Antialiasing.

Also, what is the resolution of the camera you are using?

@zedociel I Blackmagic cameras every day in 4k and everything os and looks great on a mac....

@armando @Woland - OP states that they are not using a camera - i assume it is a HDMI out from another computer, into a capture device.

You could do this in a completely different way by sending the image from one computer to another using NDI, thus eliminating the need for HDMI output / capture cards etc.

Armando

@dbini I got that, but as for the capture it should be exactly the same. My card in a sonned usbc cabinet on mac is not the same mine is Decklink quad HDMI

One of these days I really should learn how to read...

It's the hdmi output from another mac.

Resolution is 1080p60.

I tried the three video setup (scale to smallest, largest, default).

With or without antialiasing...

Anyway, i tried it on a new patch, video in watcher straight to projector, so there should be no scaling nowhere.

When i let the mouse on the link, it tells the output from the video in watcher in 1080p60

For now, i'm using spout/syphon from madmapper to have the good image quality.

Once again, the setup was tested both on mac and pc, with a decklink duo 2 and a decklink 8k pro.
