Green Day footage speed technique?

Does anyone know how they did the cool different speed technique on Green Day's "American Idiot" video?
http://www.youtube.com/watch?v=W2BwBiaSvNQ
At about :32 in (when the song goes to the chorus), each member of the band's footage is normal speed, sped up, or slowed down with a nice consistent slow camera pan across.
I suppose maybe they did this with motion tracking and masking but it seems like that would have been very difficult. But it's a very cool technique.
Any input would be much appreciated!

While it is true that it could all be tracked and roto - you could also achieve this same effect by having each member move at a different speed at the same time, in the case 2 very slow, one fast and then the clip has been sped up.
You often see similar version in rock videos where actors move very slowly and then clip is sped up to normal speed and/or played around with speed ramping, but gives a very jerky movement to the people in the scene.

Noisy blacks in keylighted green screen footage

A friend of mine hired me to do some effects for a pepsi commercial (Video Production 4th quarter final project). He gave me green screen footage of dancers, and he wanted me to key the green out, put them on a black background, and make light streaks coming from their hands. I can do all of this, but I'm having trouble getting it to look perfect. He shot on a dvx100, 24p, and I'm certain he shot at a pretty slow shutterspeed, because I'm losing half of his arm when it moves quickly. I don't think this is fixable (if it is, let me know), but it shouldn't be too distracting. My main concern is I've got a lot of noise in blacks and dark colors, mostly the male dancers jeans. I have to set the screen matte clip black to about 50 to get rid of some noise around the dancer. Is there any way to reduce the noise within the pants/dark colors?
Heres a test shot I just exported:
http://vimeo.com/1721038
Any additional advice or tips on all the effects in this project would definitely be appreciated. Thanks!

thanks for the tip about the noise, I'll try it.
As for the light streaks, your right it does look a little too 2 dimensional. I used Kramer's tutorial to create the light streaks and parent them to a null object, i made the streaks a 3d layer, but I can't figure out how to make the streaks move in 3D space with the dancer's hand being a 2D layer. The only thing I could think of is pushing in with a camera, but I would need to sillouette the dancer to prevent visible pixelation right? Or is there a way where I can move the light streaks in 3D space without sillouetting the dancer?
Thanks ahead of time!

Weird blinking screen on green screen footage

I have this problem with AE, when I RAM preview the pre-keyed green screen footage I get a colourful box of lines popping up now and then when I play the footage. It's hard to explain, but the screen looks like one of those vertical-colourful-lines that you get on the TV when the channel isn't working (On Screen Display?) I will attach the screenshot of how it looks to this discussion. Also, the footage is not missing, it's there, and the blinking only happens when I preview in AE, not when it's rendered. Thank you!

A format is just a container for a video encoded with a codec. All video, as Rick says, has a codec. Most DSLR's use an h.264 variant as their codec. The problem with that codec for certain things is that it uses interframe compression. I could get into a long explanation of this, but the short version is that it doesn't have full information for every frame. That sort of thing can sometimes get screwy in AE which uses full-frame information for every frame. This was much more of an issue in earlier versions of AE, but from CS5 onward, things are much improved. However, with multiprocessing on, sometimes you can see weirdness with these highly-compressed interframe codecs. That's why Rick is suggesting you try turning that off and clearing your cache.

11 Days in Speed has gone from 55 to 7. BT Call ce...

Title says it all really.
Infinity was installed on the 30th of April speeds were great at 55 through out the week they slowed down to 36 which was great as I was told my max speed would be 30. However over the last few days my speed has dropped to 13-16 but has gone as low a 7
I phoned BT overseas call centre and was promised that the would fix my fault by then end of the call, then BT flatly refused to do anything as I was in side the 10 days. Explained that I wasnt. 9 days into May and the 1 day in April makes 10 days. So after I and the person on the other end of the phone counted the days out in sequence and realised I had had it for 10 days, he turned around and said we dont count the first day, and your days will not be up till Midnight Friday.
Thats 12 days by my counting
I then got a very condersending story about how the internet works. "Let me explain so you will understand. When a baby is born it can not walk that is like your connection to the internet. When the baby reaches 2yrs old it can move faster but still not run, when its older still then it can run, This is like the 10 days you connection need"
All I want is my Ip profile reset as it and my max line speed have dropped from 70+ to 38.6 to 19.8
Do i have to wait till Midnight Friday or is there someone else I can ask to get my Ip profile reset.
I just want the 30 I was promised

Till I can post the BT speedtest result
Here is the quote from the email Irecieved when signing up to Infinify and Speedtest.net results from day 1 to yesterday.

How to keyout harsh shadows from green screen footage tutorial

Hello!!
I have shot a green screen footage outdoors an two clips where shot with the sun making some very harsh shadows that are impossible to key out. I am attaching two photos so that you can see what I mean. I there any other way to go around this problem without rotoscoping because unfortunately it' s not an option for me to reshoot the scene. Maybe lume key could help but I am not sure...
Any suggestion would be appreciated!! The first image is the original one. The second is with Keylight only and the third is with Keylight and Luma Key together...
Thanks
Yiannis

Duplicate your layer, key once for the light green, key a second time for the dark green, Output the mattes and combine them to create the final matte. Pre-comp the two shots and use as a garbage matte for the final key by adding a matte choker and making the pre-comp a track matte for your final key.
There are a zillion other ways but Here's what the combined matte looks like from your screenshot.

Hey all - I am just learning version 6.0.6 - can't use green screen footage

When I try to use chroma key (edit green screen footage I've shot) the option is greyed out. Thanks for the help!

Sorry to break it to you, but FCP6 is not FCPX. Go to the Final Cut Studio forum with your question.
Er, this discussion showed up as an FCPX discussion when I clicked on it. Not sure why, but i apologize if you posted it correctly in the first place....

Apparent chnage in footage speed??

Hi,
I exported a large QT to idvd using 'best performance' as it was a touch over 65mins. It is a sign language video and now, it appears that at some points the footage 'speeds up', the signing is definitely quicker, is this a quirk in the compression to fit it on the disk in best performance??
Appreciate your comment. One other thing, if I import to compressor, then to idvd, the Apple team at my store think it woul be compressed again and would see a quality loss???
Thanks.

Unless you were using a double layer disc, 65 minutes is too long for Best Performance. In iDVD 6 you would need to use Best Quality (in iDVD 7 it's called High Quality).
The earlier iApps work much better with DV content. There is no reason to go through Compressor.
What format is your content in?

What is the best way to ramp footage speed 'Green Wing style'?

I have some 720P 60fps footage to show people walking in slow motion in a hospital. Looks great, however I would like to speed them up to 'real life' pace and then slow them back down.
What the easiest way of doing this? Should I do it Motion or in FCP? Why is it so fiddly or am i missing a trick?
Any guidance greatly appreciated.
Flavio.

Getting cleaner edges with 4:1:1 miniDV green screen footage

I understand 4:1:1 miniDV footage is not so good for green screen stuff. From what I've gathered searching google, it helps to blur the U and V channels before applying a color key. How do I do that in After Effects? Does anyone know any other tricks?

You can transform the colorspace using the Channel Combiner effect. Just don't forget to transform it back after you've done your blurs. You can further refine this technique by separating the transformed channels using e.g. Shift Channels and treating each component separately. You can properly recombine them by using e.g. the Add (RGB) or Luminance (YUV) blendmode. Anothr possible trick is to duplicate the layer and use blendmodes like Color in combination with your blur, then key the resulting pre-composition. Still, the best solution (if you do this regualarly) is to look into some specialized deartifacting plugins. A good generic point to start is RevisionFX SmoothKit collection which offers a wide selection of adaptive blurs that can be used to even out the background (Median) or soften block artifacts after the keying. Plus it has the advantage of a great variety of otehr creative uses... Also check out Primatte and its built-in deartifacting mechanisms. I'm sure you can also find simialr complementary tools from other plugin vendors.

How to export green screen footage.

I recently shot on a green screen, i keyed it in after effects with keylight but want to do color correction in FINAL CUT. when i export the video it comes out with a black background instead of transparency so it doesn't allow me to composite footage over the background so i can't color correct or do anything because the clips with the black solid background are useless. how can i export the already keyed footage so that i keep the transparency for the background?????
thanks

This thread has become a mess of confusing information. Just to clarify a few points:
1GB RAM is not really enough to run AE well. Your purchase of 4GB is a smart move.
AE manages its own RAM usage, so its very possible that it may only use 20% of available RAM, depending on the contents of your project and the amount of precomping etc that you've used. Once you have the extra RAM, enabling Multi-Processor rendering is the best way to utilize RAM during the rendering process.
The "Secret" option mentioned refers to a secret preference menu in AE, which is enabled by holding the Shift key while choosing preferences. Unless there is clear evidence that your system is running out of RAM while rendering, there's no need for you to use the Secret prefs menu.
The "3 GB switch" referred to is not relevant in your case - it applies strictly to Windows XP users.
In summary, install the extra RAM and activate multi-processor rendering to speed up your renders.
Export your keyed footage using the "Lossless with alpha" Output Module in the Render Queue. This will provide transparency info when you take the footage to FCP.
Alternately, as suggested by Mylenium, do the colour correction within AE.

Footage speed altered upon ingestion

I just shot a day of performances at a children's music festival. 4 disparate cameras were employed: my panny HPX250, a borrowed panny 170, my 7D and a GoPro Hero3. I'm now ingesting the footage nto FCPX and something crazy has happened that I've never seen nor heard of:
All footage was shot 720. (the 250: 24pN, the 170: 24p; the 7D: 720 60i; the GoPro: 720 60i) All footage was ingested into FCPX with the same settings. Despite the different cameras used everything plays well together on a timeline, and I never got one of those warnings about miss-matched footage when dropping one onto a timeline.
The problem?: all the clips on from the 170 play back at about half speed. In fact, when I dropped a clip into a timeline and altered the speed 250% looked to be about right but the motion was choppy as tho frames were missing. This would mean, what? In the unaltered clips something like two out of three frames were removed and the remaining clips multiplied? Kind of like putting a strobe effect on proper footage. In addition, the audio is normal speed and it generally ends before the video does on each clip.
This problem exists to the very QT files that were created in the Events folder. Play one in the QT player and it too plays slow so something happened on the was from the camera to the hard drive.
Any ideas???
alan b
BTW: only last week I did a clean erinstall of my system upgrading to OS 10.8.3, I did a clean install of FCPX with a new download fro the AppStore. In the middle of these troubles I describe above I also trashed preferences. So...?
PS--also, I went back to the 170 and played the footage from the card itself within the camera and it plays back normally and properly.

First off, let me report that I just finished re-ingesting the 170 footage and it is now running correctly. More on that below.
--The timeline WAS 60i but, as I pointed out,, the footage was misplaying even at the root level of the QT files in the Events folder. I was only looking at them in FCPX from within the Events window. They weren't even on the timeline. However--and here is where my massive confusion with these numbers comes into play--I just checked the settings on the 250 were 720 59.94P 24pN. So help me out here: 59.94P refers to the play rate and 24pN refers to the acquisition rate? The 170 was set at 720P/24P frame rate @ "default" whatever that means.
--The 250 has even more speeds than the 170 but won't record sound if the frame rate and acquisition rate don't match. I can only figure that the "Default" notation for th 170's frame rate means a matching 23.97?
--This is where the "roads splits" so to speak. As I mention above, I now have operational clips from the 170. I just ingested the files directly from the camera into FCPX. The prior attempt was done by first copying the raw P2 files onto my HD and then importing to FCPX from those files. I don't know why that would change anything since that's exactly how ALL the footage from ALL the other cameras was handled, but that was the only difference and now I have workable files.
So, I dunno. Makes no sense to me. Maybe yous guys can make sense of it for me.

How do I make green screen footage tiny - need tiny people on my video

Ok....I've looked everywhere but I'm not having luck.
I want to take screen screen footage (people dancing) and make them tiny to place in the corners of my video.
Where do I go for tutorials on this?
Thanks.
BTW I love 6.0!!!!

Here are three quick tutorial sources to give you a start on green screening. After you do the green screen then you just have to play with the motion effects on the clip to get it to the size and position you want.

Exporting keyed out green screen footage

I've keyed out the green screen from my footage of someone standing. I now wish to export it and send to someone else to do all the graphics behind the person.
I've tried exporting as a quicktime but when they recieve the footage they can't put any background SFX in.
Help anyone?

to export your keying you will have to make sure that your export includes the corrcet alpha channel.
look in your wireframe/ image drop down menu above the clip viewer and select alpha
you will see that by keying out you are removing the alpha (white elements) from the area you dont want to keep ( ie. the blue screen) you will need to provide your fx guys with this info.
try exporting your seq as a quicktime whih supports alpha info (like animation) and choose millions + in the colors to include the alpha.
or you can provide the alpha info seperately on a qt of the same clip duration - copy the clip ad use the extract filer to copy the alpha ino to the RGB channels and provided your FX guys with both the normal clip and the B+W clip - if they know what hey are doing they can put these clips back together in their FX package to just keep the non-bluescreen areas of the clip.
oes that make sense

Flipping green screen footage causes error with background

Hi,
I have created a short 30 second video using a green screen. I realised after that I needed to flip it (I was point the wrong way!) So I dragged it into my project and then flipped it. THen when I dragged the background picture in and choose "green screen" the image is all weird. I try to change the efects, colour etc but it doesn't seem to work.
If I drag the back ground image in first and then the green screen video they merge OK but I cannot flip the green screen video once it is in project with the background image already there.
Any one have this problem and know how to fix it - or do I have to reshoot the video and point the other way!?
Thanks
Cheers
Tracy

Hi bogiesan,
Thanks for the help.
My footage is actually shot with a green floor. The problem I'm having is the final product needs to be an actor walking out with a transparent background, but casting a shadow on the floor. So that the shaow will show up no matter what background the customer decides to use the video with.
If I try applying a drop shadow or a Radial Shadow the shadow shows up BEHIND the actor not below. I must be making this 10 times harder than it needs to be.
Any Advise would be appreciated.
Thanks again,
Bob
I'm not grasping the issue, then, sorry. Just use the shadow you have captured. Setting a chromakeyer to pass the shadow is not difficult.
The problem with faking a shadow is, yes, it's ten times more difficult than getting it in the original shoot because of all the problems we've discussed. with a shadow layer there is not interaction with the feet and the 3D projection is not realistic enough to be accepted by an audience; it will always look fake. You CAN create a projected 3D shadow by carefully placing a light in a 3D scene and placing a copy of your matted character perpendicular to the light source and setting the layer to project the shadow only. But it still is not real.

White areas when keying a green screen footage.....

Hello there!
Have a look at the YouTube video link to see a peculiar problem.
Do you jappen to know of a solution around that?
http://www.youtube.com/watch?v=RD1y5-yiasw
Thanks!
Yiannis.

Yes you are right my friend....
It is a 1080i footage shot in a photographic studio with proper and even (diffused) lighting.
The comp is 1080 (resolution).
I first refined the footage (smoothed even more the green backdrop, eliminated even the slightest noise (it didn't have much anyway).
I exported it totally uncompresed (Quicktime mov - uncompressed)
and I reimprted the perfect and uncompressed clip and started apllying some effects first in order to smooth any hard edges and generally to prepare the clip for keying.
But when the actress joins her limps or arms and there is a very small area between her limps mayby Keylight cannot grab the green color in this tiny area and I get these white
edges.....
I guess that eventually I wiil have to mask the footage.....
Thanks!!
