You can do magic select as you did, then delete as you did. Then split your RGB channels and blur-delete the green channel around the edges, then re-merge your RGB channels.
I'm surprised you don't just feed the background image and the green screen into OBS or your Blackmagic ATEM and just screenshot the output! But I do recommend making a layer mask with the selection instead of just deleting it as it can make touch up much easier as well as save your bacon when you realize an hour later you cropped something you weren't meant to and you don't want to redo the entire selection process to fix it.
A lot of the green around the edge is an actual green cast - light bouncing back to you after bouncing off the background. You can do some things with back lighting, using a smaller green screen background, and more. Tough thing to solve in a home/office studio, though. The fuzziness from feathering the edges can be really noticeable in images where the person pasted in has poorly defined edges. You have a big green PCB in the photo :) , but you could also mess a bit with the color channels/curves and adjust out some of the green highlight. Just select the PCB and then invert the selection before doing so.
I usually just fuzzy select everything (without feathering) then do select->grow 1px, select->feather 4px and then delete. Obviously you have to fuss around with the values but I think it goes faster when they are global and you can see the result almost immediately and the result is stil good enough.
No need to go around, if you enable feather edges, press the delete button several times, this will progressively delete more and more area around the fuzzy edge until the set pixel value distance. You can also decrease the threshold and it'll select a larger range of green colors, making it a closer fit.
One other tool that GIMP has that works pretty well is the Foreground Select Tool. You can draw with foreground and background brushes, and it will adjust until you get a good cutout. Here is an example of how to use it. ruclips.net/video/uhRGix-x5Mg/видео.html Alternatively, you can try shooting on a white background if you know what you are going to be putting yourself into is mostly white, and then a little spillover is okay. I'd say you can also do luminance keying (using a black background) but since you wear a lot of black shirts, that wouldn't work as well.
Try "Select" -> "Grow" and then 1px or 2px... this may also remove the green outlines a bit... easy trick, not pro. and only works with higher res pics. but it works :)
I usually use blender to do greenscreen removal. The stuff it has baked in will do it effortlessly and remove the green tint around the edges too. Theres probably a way to do the exact same method in GIMP, but i havent found it yet.
Better lighting is something you really should invest time (and maybe money if you need more lights, but placement is probably more critical) in, so you dont have to deal with the green skin tint, which also should help with magic color tool working better..
You could go a step further and grow the region selected and desaturate the greens a bit. That should help remove the remaining green tinge on the outline.

You should use blue background. In some aspects blue is better to handle chromakey. Other good option could be black as well using good light sources.
agreed
If the background is uniform enough, you can also use "layer->color->color to alpha" :)
When I want to do it fast, I select rough as you did, and just enlarge the selection with one or two pixels.

I tried that but it wasn't as good as doing it manually for this image. That would work fine if you have a nice evenly lit background.

Set low threshold, then click and drag to adjust on fly, also select draw mask if you have trouble seeing if you selected too far in the wanted area.

Thanks! I've learned a lot from this. I'm trying to create better thumbnails.

Hey, Pixel peeping beats hours in the beauty salon with the tweezers LOL
Actually, you look pretty good with green hair Dave!
1996 wants magic wand and blur selection back
Step 1, properly light and separate the green screen from the subject.
Better lighting is something you really should invest time (and maybe money if you need more lights, but placement is probably more critical) in, so you dont have to deal with the green skin tint, which also should help with magic color tool working better..
Maybe it would save you time to shave your arms :-). Thanks for the GIMP lesson - it’s not the most intuitive tool, but it’s good - and free!
@3:17 Almost thought you would go into sponsor time with hair-loss-remedy.
(not really)
thats it!.. thats what i was tryin to explain on the other vid! :P
how do you stay motivated to learn?
Have some task that requires you to learn something.
time is better spent on sorting resistors.
These tips are great. Thanks Dave
To fix the hair issue next time, use gel to stop your hair sticking out, just squash it down.
Or put a cap or something, anyway sure there's some filter to apply to hair didn't look further into.
@@Joe3D Just draw the hair back in manually.
gel... or epoxy
@@difflocktwo Use the hair tool in Blender to add it back in.
I'm still using PaintShop Pro 9 from 2004. Does the job.
Me too!
Does Vegas not support chroma keying? It would be far more effective.
Disappointing that video insert did not happen in Cinelerra or Blender. Once you fall into Shareware trap, you cannot go back.
no idea what this means. A) video insert B) shareware? C) trap D) how its related to this video
Shareware? GIMP is free open source software.
@@EEVblog Meaning Free Software generally as in "Free as Air" (and not "Free as Freedom").
@@mrlithium69 Ach. Commenting wrong video. The final video insert was on the previous Green Screen video.
Well you can do Chroma Keying in Blender as well.
GIMP is a Linux program.
Not only. GIMP is a cross-platform image editor available for GNU/Linux, OS X, Windows and more operating systems.
Dang it! I've been using it on other platforms for all these years without realising it doesn't run on the platforms I used it on!
You could go a step further and grow the region selected and desaturate the greens a bit. That should help remove the remaining green tinge on the outline.
