    You can also use the circle selector rather than the colour dropper.

    Sometimes increasing the saturation before you key works well, and if the skin tones are OK on the talent, then turn the key off, use 3 way colour corrector, select hue, move to the green area and increase the green, that may help, turn the key back on.

    I find the cancel colour selection is a bit vicious and tends to turn grey purple you need to wind the power back a bit.

    There was very little in it between Robus Key and the built in keyer when I tested both, the built in one I found was better on fuzzy hair.

    The main considerations for a good key are
    1. Getting even lighting on the green backdrop behind the presenter this should be lit separately as it kills shadows. LED frosted fluorescent replacement style tubes (same colour spectrum as the face light) work well, with the fitting zip tied vertically oriented to a lighting pole.
    2. The face light should be soft with a diffuser as you don't want shadows on the green backdrop.
    3. The talent should stand at least 2 feet in front of the green background in front of the green backdrop lights, which also helps reduce the effect of green light radiating from the backdrop.
    4. Talent not to move around too much but be expressive with hands and test the hands extremities of movement first.
    5. Manual camera white balance before you start.
    6. Manual focus.
    7. The camera iris should be set to manual and the green backdrop should produce a 50% grey level, then the talent should be correctly exposed. (The old blue was a much lower luminance level and subject to more electronic noise and less people wear green than blue).
    8. Do not have mixed lighting, 3200K lights with daylight often gives a bad key.
    9. If using a phone use Movie Pro app as it supports PAL and NTSC frame rates up to 50/60p on UHD and gives manual control of the camera settings
    10. Always use a lapel or radio mic and hide the wire behind clothing - good sound is also vital.
    So there you are.

    Very very detailed answer Sir, thank you as well. For now I have Robus Key and this plugin always does a great work. Not different this time. As for other advice - I need to be prepared better before next green screen recording session. For now I do not have proper conditions according to your advices and it pays off with not so good keying. Great that good plugins exists and help non professionals to have better results though :)

    If the chromakey will be used strictly for a 'talking head' shot, New Blue Chroma Key Pro might work for you and is in the $100 range. As long
    as you are not looking for a product that handles motion or fine hair details well, this might be worth downloading the trial to test.

    I do this very simply in Edius9/X and I think this was available to do in Edius 7x.

    Turn chroma key off (untick).

    Put cursor over the talent clip.

    Open the clip layouter.

    Move your talent to the desired screen position.

    Crop any part of the image that falls off the green screen.

    In the opacity and colour section set the background colour to 100%.

    Now click on the background colour thumbnail (black) and the colour chooser opens.

    Use the colour chooser pipette on the green in the REC window and that will fill the cropped black background with the same colour as the green backdrop.

    Layouter has now provided the chroma key with a full screen of green to work with.

    Close layouter and turn on the chroma key.

    There should then only be the talent showing on black until you add a new background below the talent clip.

    Provided the talent always stays within the original green screen area when they move their arms that will be fine and yours looks OK, their left arm is nearest the edge.

    Regards

    Mike

    And how to animate this rectangle option when I would like to relocate my talent for example from left to right? Because I had to crop the ares where there was no green screen and when I use Layouter to move picture it shows me those cropped areas again. Without possibility of animation of rectangle there is no point and it doesn't work as it should I guess.

    enable rectangle is in chroma keyer of all versions of EDIUS, here is a screenshot of it in EDIUS 5

    So :
    step 1. turn off the chromakey effect on the Key channel if its applied.
    step 2. open Layouter or Transform effect and find Background color, increase opacity to 100%.
    step 3 use the Background color eyedropper to select the same chromakey color from the Edit Preview window (probably green).
    step 4 use the Layouter or transfrom effect to move or scale subject. The background should be the same color.
    step 5 turn on the Chromakey effect in the key channel (below the clip).
    Thank you very much for the detailed steps. Those worked perfect.

    Maybe try the Layouter, cropping as needed and then moving in the x direction.

    started a topic Relocating my picture on green screen

    Relocating my picture on green screen

    I captured myself speaking with green screen in the background, with me in the bottom left corner of the frame. I would like to move my location to the bottom right corner. I just cannot seem to get it in Edius 7.53, which is what I have. It will help me a lot, that way when I do chromakey, I don't have to re-record with me sitting at different positions, depending on the footage I want to overlay myself on.

    Detailed steps, or link to demo video or forum answer will help immensely.

    Regards,
