Pi5 for light control and as video player

I have to play some video and dimm some light in a presentation room. Now I'm asking if QLC+ can do what I need. In a nutshell when a button (it would be nice with a IR remote) it lower or off some dmx light and play a video. When the video end (or after a predefined time) the light came back on and waiting for the next trigger. Even nicer if it self start, if both video output can bu used so no user interface needed, and if the serial output can be used as DMX out (or a spi to serial converter). Design and build some hardware is not a problem. If the software can do the main of this task I'll glad to pay the fee for the repository and more important someone that can give me some direct support (via email o phone). Thanks.

I stopped reading your post here ... there is not such thing of a serial interface.
You need at least an open-DMX interface (which I wouldn't recommend - lag, unresponsiveness while dimming curves, etc)
The rest of your project seems doable, except for the IR-remote control... How will you fix this? In the lighting world, we never use Infrared controllers unless we have an IR device that can spit out ...
We use a Bluetooth 'clicker' to advance the presentation.

Is this a corporate event? There are solutions for integrating presentations with external controls, but you will have to invest a lot of (paying) hours before it works...
Is it worth it? Have the lights dimmed down before the video plays? Do you have an operator that can turn the knob? KISS principle: Keep It Stupid and Simple.

I'm not so good in English so don't undestand what you mean with "How will you fix this?" and " IR device that can spit out". Bluetooth clicker is not possible, a pushbuton can be used.
Not a corporate event, more like an exibition so no operator. All have to be automated.
Something like that can be used?

[edit] Deleted the complete extensive answer to your post.


I'm a native German speaker... PM me
You have to split up your project in little steps.
And you are asking us now what interface to choose.
This is a buzzzzzz-eerrrrooorrr-ccconnfflicting post of your behalf.

You cannot get a 'fix it all - what I thought was possible - when I use this interface' solution
