Infoseite // Help Blue Screen Effect



Frage von DennisP.:


Hi, I'm looking for someone to After Effects, etc. around and can help me FREE.
It is a 4sek. Scene, which I would send you.
There is a wide shot of a cabin with windows. A window and is now covered with dark-blue to black, so nothing should happen, such a mask, I still get themselves out. It is at the scene to a fixed camera, the actors in this scene jumps out the open window. Outside, 2m behind the window, we have a blue screen set. Now I would like the blue screen outside gekeyt have. There is still no new background behind which are the blue screen is merely a blue color to be replaced, so I fully with premiere keyen can. So now I can at the moment the material keyen bad, because there is no really good for a blue key is. One problem is that in the open windows, etc. of trees outside mirror that can not be, I would like the material later cut together so that it looks as if the actors from de 3OG jump and not from the EC;)

Difficult to explain my problem, I post here are some screenshots with explanations:
http://www.file-upload.net/download-900391/1.bmp.html
http://www.file-upload.net/download-900396/2.bmp.html

With the window 1 is therefore nothing happened out the blue in returnable bottles (2) should be clean against a single color to be replaced, so I use the material quite easily with Premiere keyen can. Area 3, thus reflecting the window is my biggest problem, you may see nothing outside of that is from outside of the mirror is a "gray uniform" will be the curtain on the inside is one to see, that is, half the window must Gray somehow be made, at least so that one out of nothing more can recognize. That's synonymous know, write me with questions like, or I would look mcih when someone logs. Simply write an email and you will get more accurate info, the clip, screen shots, which always synonymous.

Thank you
Dennis

I had the ever prestigious Yesterday .....

So my tip

Take for example, PhotoShop and pull a hundred frames as purely and solve the problem with 3 levels masks.

The Meihnung of my way here at.

to the reflections which you have to punch through the course and mask .... conjure away the 2 resulting levels are you doing it as a layer and summed in each frame set again.

Estimated duration of 4 sec approx 1 1 / 2 hr `= half hour for the first frame and masks all levels, more hours for another 99 frames ..... perhaps it will be synonymous 2 hours but probably so gehts s.schnellsten ..... Oh yes the blue draussen you're doing the same course, then remove and save images with alpha channel, and then they importierst in AE.

Antwort von DennisP.:

Thank you first.
My problem is, however, I do not have Photoshop available!
I have only premiere, and s.einem school computer synonymous After Effects, with which I am still not well familiar. Is there any other ways?
Is it synonymous with the whole GIMP realize? If so, how?

Space


Antwort von B.DeKid:

With GIMP

I think it already, do not use it but generally should be in the same steps as in PS go.

Space


Antwort von DennisP.:

Ok, but since I do not own Photoshop with GIMP and more weniegr do, I have no groartigen knowledge in the field.

I would be very grateful to you if you are to me the plan again in more detail would be a little more detailed description.

Would really very nice;)

Sach mal ....
Is the NEN Cut 4 sec without person?
As for the footage to SD / HD?

Have you already tried in AE?

Because you could be generally synonymous in AE make.

Lad out the 4 sec at RapidShare?

How did you get the with the later insertion of the background and the important thought of jumping young?

........................................

As I review in Gimp that bad in a short time so get out I do not think ....... sorry.

Also explained in the PS is not .... and yes you have no version, so ....

I think if you fit something in AE are at least you get the window area by keying tracking mask away. And the rest may still be synonymous .... Ps there is only conditionally required.

...........................................

Well post times on RapidShare un I kuck me at times ..... but something to mention, because in the pictures rum retouch grad is not so simple as building better gewerkstelligen.

Question - Does my grad ... sach you the Backraiund plus the jumping boys later in the window reflected in the sequence ... Because you have to yes, because my environment is reflected in one window.

.....

Good then to meld Dich mal alla ...

PS:
Page VideoCopilot the property had been through but you So what AE is concerned is tracking and keying techniques levels "refreshed"?
If not go look http://www.videocopilot.net/tutorials.html times
there in the tutorials gabs as synonymous with what automotive glass and so delicate matters.

I kuck me tonight s.ok times

Antwort von B.DeKid:

Gude boss ....

so I got me the prestigious times .....

I imagine the bottom times a Picture out of the first frame of the clip, all white in the window is already transparent.

The problem is what is only the window is right, because you can punch through just as the mirrored background made it away.

Probs are points 1 and 2 of your request.

So where do I start .... hmmm

Ok

So the young rausspringt ...

Since the material is half he ever violent streaks, synonymous ISTT the shutter speed too long, the worse the whole even more. If he jumps out the window or on board jumps changing the light ratio was synonymous not just good will.

The window left ......

The boy in the mirror can (must) with rübergenommen, the board must, however, from the Picture ..... Through use of the stamp could be now While the table disappear, but by the actions Inaccurate stamp, it would come to flicker.

-------------------------

Ich hab mal ca 10 images where the boy jumps .... It worked, I only made the boys brought out the picture .... The streaks have almost no masking to .... the frames are so strong "blurred" that somehow has no purpose to try it next.

..................................

In order to make s short .... the material is not.
You have your newly Rotate. Anything else would not lead to desired results.

So I would draussen s.der window side panel Styropur stick to Spieglung in the window to avoid (aka Scheubeck flap)

The panel would I wegschieben or even leave that should be no preference.

Screen and jacking the spotlight again. (PS it actually looks as if the top piece is missing)

The Camera on MANUALLY not automatic .... Shutterspeed up for about 1 / 200.

The classroom illuminate a lamp next to the left of the window wall along s.der rays can bottom to the top of reflexes in order to avoid the right pane.

Rear of the young can illuminate but slightly oblique of right to left, bottom to top .... reflexes in the left window to prevent ......

.................................................. ...............

Because I had about the first frame as a still image and then take only the blank jumping and the boys JungenSpieglung drüber mapping, but it looks very modest.

.................................................. ................

So as I said have your newly drehn.

Even if your material would now Progressiv store, you versaut Picture of the shutter.

IMPORTANT NOTE KEIE AUTOMATIC, which makes the light broken.

So I'm sorry but by re-rotating saves a lot of your time .... goes out Saturday morning and turned in its new hour.

PS what would be synonymous to the young only in a gymnasium on a pedestal to jump to only the young and to have these in the picture below to map ....... but that is under the given abilities hardly realizable cash ...

Antwort von DennisP.:

Ok, now we will probably s.Sonntag after turning.
I register again if I have the material in the box hab.
Thank you in advance, but for all the help.

Greeting

Space


Antwort von B.DeKid:

No Prob .... so after the turn is better.
If you have other tips for light, or want to tell about it.
If you help the new material you need meld ok, can help.

Sorry but I sat here yesterday with his colleague and we both were in agreement that this material not to edit it, without all the really foul, in terms of quality, and that would be really unfortunate if you already have a lot of trouble . And do not worry but sometimes synonymous professionals must re-turn.

Not everything can be in the post-production regulate!.)

Alla much success and fun s.Sonntag times and then let's see how it has become.

Antwort von DennisP.:

So if you already have a concrete idea as you think with the light will look good. Can you like to explain here, I will try the best to implement and see if it works / works;)

At Lichttechnik fortunately we have a lot to dispose of real film 2500W lamps, Baustarhler over 500W to 100W little daylight lamps. Everything;)
Is it your opinion recommended the scene for something to turn darker environment, ie when the sun just is not there, or even s.Abend, so now of course nciht in total darkness, but even so, the sun the blue screen nciht further aufhellt and the synonymous already s.einigen bodies into the white goes on.

If you have tips or otherwise, I'm open to everything.

Thank you.

Antwort von B.DeKid:

Sure do ne times after drawing ....

Whether day or night light is only partially important, through the "blinkered" s.der exterior side of the window you avoid solar reflections largely .....

Antwort von B.DeKid:

So .....
Have you times 2 pictures one shows the inside and the other outside.

Interior:
As mentioned above the lights of oblique bottom to top, I would say. The s.lassen the room lighting the lamp will show up ..... The edges s.dder wall ceiling must be easily recognizable bar in the window without spots reflect on the "wall plate" to produce.

A lamp s.die front window, one beside the camera or the middle of the area A of the starting position behind the boy.

The objective should be no reflections on the windows to throw and when the boy jumps into the window, no light auftretten changes.
The shadow of the boy should be gently fail.

Exterior:

If the light is far from the house from under oblique and placed on the windows around the screen to illuminate.
Light source of the top light can be no further comment about this spotlight.

If the screen is the substance can be examined, then synonymous to security still light behind the screen.
Ensure that there are no spots on the screen form, otherwise as much light as it goes. (Of course, not so much by the glow of the window frame. Dear with the screen next to the rear of go is always beneficial!

"Blinkered" s.Fenster ensures the outdoor light shows no reflexes and is synonymous not reflected in the window ...... Illuminated the "blinker" is not. It may be synonymous 2 blinkers a link to a law.
Shall be white not black. If you s.Fenster but then when you stand and the arm rausstreckst slight greenish tint sehn I was with the blinkers Black Mülltute Überziehn Screen ...... Or a piece wegruecken.

.................................................. .................................................. .

Aperture small keep shutter speed high ...... if thou hast set up the scene are you doing multiple takes ..... You are changing the Shutterzeit ..... How did you clean later templates where you get the best looking.
If no light meter is because you can see the automatic shutter setting and show films then manually set the stage and go up next .....

The aim should be a possible peaceful Still image view to be obtained from the movements. The movements easily shakes at high Shutterspeed settings, this is not really interesting. But the scene is too short and the keying is here and now the most important aspect.
Also yes you take 2 -3 different high shutter settings later so yes you the best s.Keying and liquid Picture raussuchen can.
...........................

Tip you ever think a board with the shutter / aperture settings
before each new take in the camera so you have good overview NEN later.

I would of each shutter setting 3 Takes drehn and then if you are the optimum setting of the shutter Aperture .... you've found the Take raussuchen where the face and the movement across s.besten come from it. Better safe than sorry.

So that should be gewessen it, I'm curious how the end result looks like.

Please but this time on the upper edge of the eighth !!!!!!!!!!!!

Alla meld ask yourself if there is or your ready because since.

MfG
B. DeKid

PS. Oh yes, if somewhere spots auftretten then with the lights dim as fabric - hauptsache the light is soft and yet sufficient.

PS2: Is my grad mal so ..... The sharpness synonymous manual set, please! This young set into the window and Sharpen - finished.
