Chroma key plugin

Jim_Nevin

I use the Veescope SoftLyght keyed ($40) with excellent results. There is a free trial.

It is a Quartz Composer plugin that you will have to save as a QC composition in order to access within Izzy

@Michel,

Here is where I found the links below:

Here are a few links to the Compositions I found:

this composition doesn't work on my MAc:

This is the one I modified:

This is another one which I also tried to modify:

Am still having problems getting clean edges.

I'll check out Jim Nevis's suggestion (if it isn't to slow for my machine).

Thanks,

@Jim_Nevin,

I just downloaded the demo version of Veescope SoftLyght keyed. How do I save the plugin as a Composition?

I found the plugin but can't figure out how to convert it.

Thanks for any info.

Ask the Veescope Key guys (support@dvdxdv.com about their "VeescopeKeyImageUnit" version of VeescopeKey.

It gives you a CI Image version that is directly accessible within Isadora. I don't remember if they let me try that as a trial or not. It provides an excellent key from my experience.

@Jim_Nevin Thanks, I just wrote them. Are you working in SD or HD?

@Jim_Nevin

Here is the response from DVDxDV to my email asking for info on the "VeescopeKeyImageUnit":

"720x520 has color resolution of 360x260 because it 4:1:1 color. This is why you are having edging issues. To get better resolution, you need a higher Rez camera or a hdmi input from your camera.
Veescope Live for iOS or Veescope Live for Mac will both help give you better quality keying."

Unfortunately I think i need to work in SD (processing power of my old MacbookPro). They didn't mention the "VeescopeKeyImageUnit". Could you give me a littler more info on which product you bought, what resolution you work in, and on if you had to modify it in QC to work in Isadora. Thanks so much.

@Michel,

did you have a chance to look into any of the Chroma Key QC Comps?

@ ursullivision
No, sorry I didn't have time yet. Just looked inside it today and played a bit around. The nicest edges comes from THIS qc patch. But I coudn't sort out why choosing a color doesn't work properly.

Maybe someone else?
Or if I have more time I will give it another try.

Best,
Michel

@Michel,

the QC Patch you said makes the best edges is the one I can't open. Darn!

Thanks for checking it out,

Well, I'm still desperately looking for a CI Chroma Key Actor. The QC patches seem to be buggy (not surprising as I'm new to QC), and ioio's plug in requires going from image to video and back.

Anyone found a decent solution?

Thanks,

Michel

So try the one you can't open that works fine for me. See attached qc patch.

Best

@Michel,

thanks, I'll try it out this weekend.

@Michel,

so I finally tried the patch (actually a while back), and strangely the video coming in was running at an extremely slow frame rate (although my input is SD).

Not being very good at QC I gave up. At least this time I saw some video.

Thanks,
