Video screen effect

Hi, was wondering if someone could help me pls! I am doing a title sequence for a charity cabaret I was involved in organising, had it filmed and now Im editing it together. Im doing it up like the Saturday Night Live titles (big fan!) I've used footage I have taken from around London of theatres etc. mucked around with them in photoshop freezeframed them taken out the original theatre signs and replaced them with either pictures or strobed video footage. Im doing one of them in Picadilly Circus, bit fiddly, I want to try and mimic the video screen effect that you get. What I mean is the small lines that make up a video screen, so it looks vaguely connected to the picture. I;ve tried some filiters, but none of them look good. Halftone kind of works but its in black and white, I want to keep it in colour. I have tried doing a texture screen but the shapes dont seem to work at all. I hope Ive explained myself well! Any help would be greatly appreciated thanks!

Just came up with an idea - take the stripes generator, rotate it, put a compound blur on it and feed that with the image you want to do the line-screen with, then put a threshold on that and voilá!
Here's a project that demonstrates...
Is this what you had in mind?

How do I stop those effects in the video screen?

How do I stop those effects in the video screen?
cube spins, pictures popping up, etc.
I've looked in all the menus and in iChat Help, but I can't locate the off button.

Hi Richard,
Is this a camcorder ?
If so it is from the camera in demo mode.
You need to set it to Camera mode with the tape out like you were going to strat recording.
You would use the same feed to record direct to a VCR on use a TV as monitor.

JMenuItem covered by video screen

the JMenuItem is covered by the video screen
how do we overcome this?

I don't know what you mean by video screen. What kind of component is it.
This effect usually comes from mixing Swing and AWT components.
Make sure you are using javax.swing.JPanel instead of java.awt.Panel etc.

Video/Screen Sharing via 3G connection not possible - port restrictions?

I'm running Jabber-based iChat AV 5.0.3 sessions from my MBP connected to the Internet via a wireless USB modem 3G/UMTS (German Telekom D1 network). My buddies are connected to the Internet via regular broadband connections (DSL). I have set up a hosted Jabber server via Dreamhost (without SSL, port 5222 used).
Status Quo:
- Contact status of remote Jabber users shows up properly. All buttons (text chat, screen sharing, video) are available (not greyed out) on both sides.
- Text chat works fine.
- Video chat and screen sharing can be invoked from both sides (confirmation window shows up), but after confirmation the initiation process doesn't finish successfully. The video/screen sharing session doesn't run. *iChat AV shows a message indicating that it doesn't receive an answer from the remote user device.* If the iChat session is initiated from a buddy's computer, the buddy gets the same message respectively.
- For testing purposes, I changed the internet connection on my MBP from the mobile 3G USB modem to a regular *DSL broadband connection (same ISP, German Telekom). In this scenario, video/audio calls and screen sharing work flawlessly!* Therefore, I assume that the problems in 3G connection mode is caused by the ISP (German Telekom) blocking/restricting ports required by iChat AV for initiating the video call and streaming the data on their 3G network.
Is there any way to bypass ISP restrictions, by either changing specific iChat AV port settings on both ends (client devices) or by port forwarding? If yes, which settings should I change? Unfortunately, it's couldn't find any document indicating which ports are opened/allowed by German Telekom's 2G/3G (GSM/UMTS) network.
Below is an excerpt of the error message produced by iChat AV:

Hi,
Does this 3G device have any set up functions that are on your Mac ?
If it does not it is likely that it is wide open to all Port (65535 of them).
I presume that in System Preferences > Network you see a Public IP when using this device ?
Again this would tend to pint to all the ports being open.
Is there anything on the ISP's web site that suggests this device is unsuitable to be used with VoIP or SIP connections ?
VoIP (Voice over the Internet) uses the SIP connection process the way iChat does.
Most likely the issues is the way packets are sent.
When you do a download, for instance, do you find the speed increases in the first few minutes ?
When some data packets are sent over the Internet the next one is not sent until confirmation that the first has arrived.
This Latency effects Point to Point WiFi (antenna to Dish on House) and satellite connections mostly particularly when it is a two way thing.
It can effect Mobile/Cell phone type connections.
What sort of Speeds are you getting on the 3G device ?
http://www.speedtest.net/
Do these seem to get faster as the time proceeds ? (this can be difficult to spot).
The Log mentions one end being at just over 2Gbps although it does not make it clear which end.
As the Remote end is the end that reports "Router: Port Restricted" and it works over standard DSL we have to presume they have the ports open.
You could try restricting iChat 's Bandwidth in iChat menu > Preferences > Video Section to 500kbps (try it at both ends)
If that does not work try 200kbps
This may stop iChat from trying to send data too Fast for the Network Connections.
Realistically there are a few too many variables here.
It could be Speed of data throughout at the Initiation point. (Slow Start up of data transfer)
It could be an Internal setting preventing SIP.
It could be that the 3G network sends and receives data by different routes.
(I have seen this once when a ISP was repairing some Cabling. To maintain end user speeds they managed their own network to split Incoming and outgoing data to the end point.)
iChat does not like this as it checks the IPs and the Hops (number of intermediate stages/servers) and if the data is different it will not connect (Man in the Middle attack protection).
I can't remember the last time I knew of someone being successful with either an 3G USB dongle or a 3G phone as Modem (internet Sharing).
Despite my ideas I think you will be unlucky and this will not work.

Blue object on green background for green screen effect?

Hi. I am inserting an image into my video and need the background to be invisible. I use the green screen/blue screen feature, but it doesn't work because the picture I am using is of a blue object. A blue object on a green background. The green background disappears but the blue object turns brown. Is there any way I can exclude my blue object from the green screen/blue screen effect? Thank you.

Trying to reenact your problem .... no luck, green screen works :
ok, my 'green screen' is a graphic, offering the perfect green-bg
can you apply a screen-shot of your green-screen recording in your next post?
maybe, your blue is too greenish… ?
Play with the color-correction tool (red arrows)… maybe you can fix it that way....

How can I create a video with effects using my ipad?

How can I create a video with effects (sepia, B&W, Negative, oval or any other shape borders) using my ipad? I would Like to keep a higher res and also be able to shrink it down to email or send in a MMS. Or should I just upload it to my PC and mess with it there? Some of the apps I have are very easy to use compared to the learning curve needed for video editing software.
Thanks

Thats the Problem . . . how many apps do I have to try until I find the one I want? I noticed a few will render the video thus losing its original size. When I went to edit it more in iMovie the video was smaller--not good. And what software do you suggest, Templeton, for the PC? I love the apps because they are easy. I dont have hours to mess around on a software to figure out if its something I want. Im looking for simplicity. Maybe Ill get more into it later. I just want to record simple video of my playing the guitar for self analysis and create a short video for family and friends.
Apps:
iMovie
CinemaFXV
VideoFix
Cartoonatic
Video illusion
VidEditor
Software:
Windows Movie maker (wont accept .mov files)
After Effects (Too little time, so much to learn)
Wondershare (Very easy but little choices)
VideoPad (Again. Few choices)

Screen effect in Photoshop.

Hi, everyone.
I am trying to create a screen effect with Photoshop but can't seem to find the right way to do it. The screen I wish to create will be used to cover photos and give the illusion they are seen through screen door or something similar. I assume the effect is created with black dots equally spaced on a transparent background and saved as a PNG image. I can't figure out how to do it and how to make this dot pattern repetitive to fill the hole are of my image (or transparent background).
Here is a link to the effect I wish to duplicate:
http://themes.themegoods.com/?theme=DK
Thank you in advance.

Hi, csuebele and JJMack,
Thanks to your help I have finally figured out how to do this.
I captured a screen shot of the effect I was trying to duplicate at the address I provided:
http://themes.themegoods.com/?theme=DK
After that I opened that screen capture and enlarged it in Photoshop until I could see the individual pixels. The pattern used for that screen is a 3 by 3 pixels square with only the upper left most pixel black while all others are transparent. So I created a pattern just like that: transparent background, 3 pixels by 3 pixels square and painted the upper left one black. After that I saved it as a pattern,
Now when I apply that pattern as an overlay to my images it gives me precisely the same effect on the link. Great ! It gives the images the same effect.
Thank you very much to both of you for your help with my question. I really appreciate it !

Scrambled video screen from podcasts

The video screen on my 2-month old iPod Nano is scrambled on podcasts such as "Photoshop TV" podcast. Still pictures and type are good and everything else works perfectly. All searches to this point have been unsuccessful in solving this problem. Any help would be greatly appreciated.

Okay, didn't realize my Nano didn't support video. So that answers my question. Will need to invest in an iPod that does. Thanks so much for the help. --glemac

When uploading videos to iWeb, the video screen gets cut off at the top. It only happens in Firefox, but not in Safari.

When uploading videos to iWeb, the video screen gets cut off at the top. It only happens in Firefox, but not in Safari. Has anybody else had this problem?

I'm using pure HTML5 for mobile websites although you need to provide an OGG file for Firefox. See the movie page on this site...
http://mobile.ezmacwebdesign.com/
If you don't have an iPhone, grab the browser handle and drag it to the left to reduce the width to see how it responds to mobile devices' fixed width browsers .
This will play in all modern browsers and on mobile devices. You can use QuickTime Pro for the OGG or OGV conversion or get the freeware Miro Video Converter...
http://www.iwebformusicians.com/Website-Movie-Video/Easy-Movie-Player.html
If you only want to upload an MP4, you can use a flash fallback player and this will cover Firefox and those geriatrics that still use older versions of Internet Explorer....

http://www.iwebformusicians.com/Website-Movie-Video/Fallback-To-Flash.html
http://www.iwebformusicians.com/Website-Movie-Video/JW-Media-Player.html
If you use any of the four fallback players above, take advantage of the fact that you can add a poster image and stop the video file from preloading. This makes for a faster page download time.
You can also achieve this using HTML5 by adding preload="none" and poster="URL to the poster image" into the code shown on this page...

Video screen capture capability for ios5??

Question 2: is it available for the iphone 4 with ios5?

Did you figure out how to capture video yet?

Green screen effect?

is there a way in lightroom to like erase the background. like selecting a certain color and replace it with another image? like a green screen effect? im asking for lightroom because the computers in the studio where i work uses that only from adobe

Lightroom does not support this type of image editing or anything remotely close to it, and I very much doubt that it ever will. I suggest that you have a look at Photoshop, which is also an Adobe product, and is capable of doing what you describe.

Using 'Screen' effect overtop of a spot color

Hi there,
This forum has been great to me so far and I hope it continues. I have a line drawing that I have set at 100% black (0,0,0,100). I have placed it overtop of a spot color and added the 'Screen' 100% effect to it. Unfortunately when view it in overprint preview and save a pdf print file the effect doesn't show and the entire line drawing dissapears? Looking for answers. Thank you.

As long as it's white I don't think it'll be a problem - but the screen effect probably won't do that much anyway in this case.
Preparing for press printing with spotcolors mixed with other colors needs planning accordingly to ensure good results - and I'm not sure where this one is ending up.
I this case to ensure correct separation, I would just tint the spotcolor until target reached.
Torben.
