Green Screen Pan Shot

The footage I am working with is a steady pan that includes two picture frames that have been green screened. Unfortunalty, within the moving shot there is another green image that I do not want omitted. How do I separate this from the picture frames? Also I am using motion tracking to add the desired photos into the green screened picture frames. Is this correct or are there better ways to achieve this?

There's really no need for the green screens. You could just track and apply the corner pin data to what you want to put in the frames.
P.S Your "special vase" need a wash!

Can Motion 5 replace a green screen and blue screen in the same shot?

Can Motion 5 replace a green screen and blue screen in the same shot? I would like to replace a green screen with one image, and a blue screen with another.

Fox gives a good example for keying green & blue (or any other color) from the same shot. I'd suggest doing a few things to get better accuracy.
First, the motion keyer always removes the color it detects the most of by default (blue/green). You can override this by setting the Strength parameter to zero, then use the Color sample tool to select the color you want. The advantage is motion will do a good job of targeting only the hue (color) that you want to remove and set an appropriate starting softness. It also will remove spill based on this color. Looking at Fox's example movie and the shot, I'd approach the same shot this way:
Remove the Blue
1. Apply the keyer and set the strength to zero.
2. Use the Sample Color tool and select the blue (or other color) to be removed.
3. Decrease the spill level (if needed). In Fox's example the spill from the blue glasses is going to be minimal, especially compared to the green screen, your shot may need different adjustments. Only de-spilling what you need to will give you more accurate color right away and minimize additional color correction that might be needed later.
4. Use the Color selection tools (Chroma wheel/Luma bar) to fine tune. Ideally you want a minimal tolerance, the inner selection, with a nice fall off, the outer selection. Try with the Scrub boxes setting first, then switch to manual if you need more control. Again see Fox's example.
Remove Green
It's the same as the blue, you could apply the keyed to the same clip or a parent group, at this point it's many user preference.
With these techniques you can remove any color from a shot or create a mask based on a color. BTW, as you are learning to use the keyer I'd highly recommend having the Color Selection open so you can see the graphs. These give you real time feedback as you make selections and changes with the Strength, Refine and Color selection tools. Watch what happens as you make selection or changes, sometimes the problem area is actually in the brightness not the color, or the softness may change more than the tolerance selection. Observing what is happening in these graphs will help you figure out wha to change and speed things up.

Green screen compositing, why does red specs appear on my finish composition

Hi, I am compositing some green screen scenes. When fininshed, I render them into Quicktime .mov's (using Avid DNXHD codec). When I play them back on my computer, they look fine. But I tested them on a fairly new 52" LCD television, and saw little red spots appear in certain places. Why would these red spots appear on certain televisions, and not on others, likewise, why would I not see them on my monitor?
Some info about the shots,
It is a green screen background shot, which had blue trackers, shot in 1280x720p. The backgrounds are 8 bit compositions created in a program called blender. The editing and compositing was done within After Effects CS6
Any help about the mystery of the red specks, maybe hotspots, would be appreciated.
Thanks

A picture's worth a thousand words.... Could be anything, but most likely you're using bad encoding settings and make a mess of the color ranges....

Green screen filming ..indoors or outdoors ?

If i'm to drop people onto a film footage of a forest...
Do I film the people on a green screen in daylight ? as most instruction videos I've seen have the green screen in a garage or indoors place...would it make a difference ?
Or best to keep indoors and light for the best daylight i can achieve ?
I will be dropping the people onto a forest film.
Thanks

I think I'd rent the HMI's.. they are lights whose color temperature matches daylight. Putting blue filters over lamps will cut down the light too much I'd think. If you're near any lighting and grip rental houses, they'll likely have HMI lighting for rent. You could just use incandescent lighting, but the color correction may drive you nuts in post to sell the composite. The blue filter idea should be tested before you're knee deep in production too I'd suggest.
Doing chroma keys isn't easy and it must be lit properly. The trick is to keep the subjects away from an evenly lit green screen. and shot with a camera that records in a 4:2:2 color space... or the keys are nigh impossible. i.e. no DV, no HDV... P2 at least... I'd suggest you read up on this at http://www.creativecow.net. Search the articles there, I'm sure there's one on doing green screen work.

I have footage that needs to be green screened. One of the cameras zoomed and panned, is there anyway to lock foreground and background so the motion is consistent

I shot two cameras for green screen editing but one of the operators zoomed and panned so the key is good but when the camera zooms it looks like the subjects are floating, any idea how to synchronize the foreground to background

I think you will need the camera tracker effect in AfterEffects, It would be best to ask in their forum.

Moving a subject from left to right if shot in front of green screen

Here's my question:
If I shoot an interview with someone who sits right in front of a green screen in the middle, is there any way I can move that person, and that person only, to the left or right of the frame after it's shot? I have seen it in VH1 and it looks great. Do I have to roroscope? Would I have to shoot the interview 3 times in front of the green screen, One on the left side, One on the right side, and one in the middle?
Any help would be appreciated
Thanks in advance

Well, assuming that you are keying out the entire background, you're left with the subject pretty much just floating in space. So its pretty simple to just move your subject layer to either side of the frame, independent of whatever background layer you plan to put behind him/her.
Of course, as you move this person, their eyeline may appear as if they're looking at different subjects.
If you have no keyed out the entire background, I'm afraid you are left to play with masks.

When keying a green screen shot, the image being keyed goes a little out of focus when the effect is applied. How do you keep it sharp?

When keying a green screen shot, the primary image goes slightly out of focus when the effect is placed. What am I doing wrong??

Make a letterbox in Photoshop -two black stripes and a hole in the middle, place it on a higher video track.

How can I use iMovie on my ipad mini to create a video from still shots using a green screen?

In my physics class, I am doing a project where we are taking pictures to create a movie, and we are usign a green screen. I know that iMovie on the mac devices is able to transfer photos and videos from a green screen so that you are able to insert backgrounds where the green screen is. Is there any way to be able to change the settings on the iPad mini to be able to do the same things with a green screen and backgrounds?

Also, I tried changing my primary email on Fb to what it was years ago, etc and I still wasn't able to delete the account.

Green screen video resizing/moving up/down/left /right on background shot

When using green screen in Imovie is it possible to re position your green screen footage on the background ie:- up/down/left/right and also resize ?
many thanks for any help on this.

I haven't found any, though one can use crop or ken burns effects. I am sure there is a trick, like exporting the green screen video into keynote or something, but I haven't found a way in iMovie.

Which material is better for Green Screen?

Which material is better for Green Screen? Polyester or Muslin??

woof
check this out...is same as my link above type material.. is not shiny..is matte...spongy...stretchy...nice. If you have worked an 18 hour day on job and don't wanna do the 10 hour turnaround for next call time...you can even "sleep on it ".

go grips ! ( or was that go vikings ? ! )
ps.. the 'comments' on that web site for pan am are from non pro's... silly ...
they are not comments that have a clue whats up in pro work...sorry..but is fact.
the DIT station ( live during shots ) could mix the background and live shots live...so you 'see' on monitor what you get at end of edit and keying.
trust me, this is very advanced.
dont worry about the small stuff.. just test and shoot and test and shoot and get what you need.. live ..no post work is good work.
dont know how else to say this.. guess you had to be there.
try to imagine live and keyed at same time...melt the pictures in link you see in your head...original with screen, end result with key...is fun

Green Screen on Viewer

I loaded mpeg file to Premier Elements 8 and could see preview in right pane but could not see movie in viewer of left pane filled with green screen. When I clicked the viewer, I could see the shot normally. But it turned to green screen again when I click play button. I encoded the file from mpeg to avi with MPEG Streamclip and tried again but it didn't improve. Please give me any advice, setting up etc...
Regards,
taitaijp

When you say "it didn't improve" do you mean that the converted AVI showed up as green in your project also?
Look at the timeline when you place the clip on it. Is there a red line above your clip? That indicates that the clip needs to be rendered. Press Enter and the red line will turn green. The resultant video will look much improved.
Whenever you load a non-DV format (including MPEG) into Premiere Elements, the program needs to conform it. Depending on how long this clip is, this can take a couple of minutes or as long as five. But, as its conforming, it will display the symptoms you describe -- It will not play, although you can scrub to specific frames. Usually this conforming is represented by a a green progress bar in the lower right of the program.
Give the MPEG or AVI a few minutes to conform in the program. Chances are it will play just fine in a couple of minutes.

Green screen syncing problem

I shot two cameras for green screen editing but one of the operators zoomed and panned so the key is good but when the camera zooms it looks like the subjects are floating, any idea how to synchronize the foreground to background

Hopefully there is something in your frame that is fixed that you can track for scale and rotation. The procedure would be to stop all the camera movement by stabilizing the footage then perform your key then scale as necessary to fix the framing problem. And by stabilize, I do not mean warp stabilize. That will do you know good and cannot work on the green screen anyway. I mean you lock in scale and rotation so that something, like the actors torso, does not moved in the frame at all. Only then do you have a chance of removing the offensive motion. If you could post the shot then I could give you some ideas. I have had to do this several times because of inexperienced camera operators. I always felt like sending them a bill.

Can't figure out why green screen is pixelating!

I had terrible problems with square pixelating on my production.
any ideas on what caused this... we played with saturations all day with no effect. I did have a empty green "last frame". It seemed nothing we could do would help!
I filmed with a Sony DCR-SR68 HandyCam in the highest quality and the background I chose from a Free Use source for greenscreen back grounds online.
I hope you can give me some insight here...every tutorial i have watched made green screen in iMovie look very simple... and yet we could not figure out why this pixelation was occurring!
reasons i wondered about:
green screen is too light?
...however i have seen screens look a lot worse and work
something to do with how i am filming?
...i realized that "facial recognition" was turned on which caused the camera shot
to move a little as i moved
am i too close to screen?
...i was about a foot away from screen (but no shadows) and camera was about a yard in front of
me
if anyone wants same rendering or screen shots let me know and I can email some!
Let me know what you think and if you need anymore info!
Thanks in advance for all your help!

Earl...
I know you said you reformatted the drive but just in case, how much free space on the startup disk?
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you have a minimum of 15% free disk space.
fresh install of 10.4.7
Most recent version for Tiger is v10.4.11. Have you tried updating the software from the Apple menu > Software Update?

The best green screen work flow for FCPX

I over 300 clips done in green screen. Some clips are 10 seconds some are 5 min. I need to prep them for import into Motion 5 where they will be keyed and background graphics will be added.
The way im doing it now is dragging the chosen shots into one storyline then do one massive export of all the clips to one clip.
Does anybody have a better way of doing this?

Right now there is no roundtripping available for clips in FCPX --> Motion --> FCPX. Your only option is via your current method (export/reimport), or as James said, start your workflow inside Motion.
Use the Feedback page to enter the feature request to Apple (I've done this already myself).

Remove Green Screen with Adobe Photoshop Elements

Hi,
I have setup a Green Screen in my home. I took some pictures of my wife with the Green Screen Background and want to remove the Green Screen and replace with a different background. I was able to do this via the Adobe Premiere Elements 7.0 but need help with the Photoshop Elements.
Any help is appreciated.

FWIW, She is really easy to select on that green screen if you use a few tricks. The screen shots are in CS3 my preference but worked with Elements limitations to show you how easy she can be selected without any filters.
My end product doesn't look as good as Mark's though. That's a tough act to follow. Thought I'd post this anyway just in case you couldn't get that filter to work in Photoshop Elements 7,
First, make a copy of the image and desaturate it to make it black and white. I prefer using Hue/Saturation from the image menu (CTRL U) and moving desat slider down to -100. Next Invert it (CTRL I), then run levels from the image menu (CTRL L) to push the image towards pure white and black...well close. It should look something like this when these steps are done.
Copy this image to a new layer. (Just in case something goes wrong so you don't have to repeat the last steps). Leave the copy in Normal blend mode. Grab your paint brush tool. Set the brush tool's mode to Overlay blend mode. You will use black and white paint to push dark gray to black and light gray to white. When done, it should look something like this:
Not perfect...I did this really fast and was a bit sloppy and didn't get all of my light grays pushed to whites. Probably not a problem for the hair edges but would need to be fixed for face and body areas as this will be a mask to make the selection.
Select mask that was just made and copy it into your clipboard. Select<All; Edit<Copy. Create and adustment layer mask that has a mask. I used the Solid Color Fill Adjustment layer. Alt click the mask of the adjustment layer you created. It will turn the document white. This is because the mask is now the focus. Now paste. Edit<Paste. This will paste the above mask into the adjustment layer mask. Now, either alt click the mask or click on another layer to remove the focus from the mask. You'll use this adjustment layer as a base to a clipping mask. See next paragraph.
The Solid color fill layer (or whatever you picked) with your mask is going to be the base on which your selection will be built. Create a copy of your original image up above this base layer. Now, hold in the alt key and move your curser in the layers pallete to the line separating these two layers. Notice the cursor changes to an odd symbol...a solid ring and a hollow ring with an arrow. Click the palette on the line separating these two layers. (Release alt key when done.) She should now be covering the mask you created. Areas that are white in the adjustment layer mask will show the original image; areas in black in the adjustment layer mask will be transparent. (Areas that contain shades of gray would be semi-transparent...amount based on the gray's brightness value.)
For the green cast on the edges, I removed that by using a Hue/Saturation adjustment layer to remove the green spill over. If you only wanted to effect the girl and not a new background add it to clipping mask. (Same way...alt click the line between her image and the Hue/Saturation layer.)
Not perfect but this is what I came up with based on the above mask:
