Blackmagic plugin (output unresolved issue)

**I’m using UE composure to compose an SDI video source coming from Blackmagic DeckLink then i run it with a CG layer into a compositing pass and output the comp using the plugin’s output for AR purpose.

The issue is that the output shows bad compression quality, one example you lose quality on reflective surfaces**
Several users experienced a the same problem and there is no discussion thread talking about this.

i’m using Blackmagic Design DeckLink Duo 2

**on the left of this screenshot is the output **result from the blackmagic’s plugin in Unreal Engine

i’m open to suggestions, if you have similar problem please share it here. my intent is to solve this and find out if its a technical issue or a plugin bug.

i also like to add that i posted this issue in the Q&A section hoping the post get more votes to reach the developer’s attention and get some preliminary answers regarding this issue. see the link below:…gin-issue.html

Hi Naseem! I have the same problem! Would be great if someone from Epic could give us input how to solve this?


yes i figured that is a common problem, the only way i can think of solving this is by composing out a fill and a garbage matte and do it in OBS, i just hope it doesn’t screw the latency. meanwhile i would appreciate to get that solved in unreal instead of mounting another PC just to solve the compositing in unreal witch it should work.

It would be great for some help…!

Solved and the way it works is color conversion, its up to you if you want to apply this on media plate only or in the comp’s transform pass
