I am using camtasia studio for screen record. for small portion of my screen I want to zoom camera/recording area.
How can I zoom area when recording?
I just had the same need. I wanted to zoom in on an increasing counter in a callout window. I wanted the zoomed in "callout" to be perfectly synchronized with the actual video that was running.
I clipped the video I wanted zoomed in and put it in exactly the same location on an additional track above. Then, I copied the clip to a new project. Using the pan and zoom tools, I created a smaller video of just what I wanted by selecting the video size and positioning the pan window after setting my zoom.
It was easy to produce the video to a new WMV file and import that back into my original project. I used the copied clip as a guide of where to place the zoomed in video on the timeline. Finally, I removed the copied clip from the timeline because I no longer needed it.
For my needs, all I did was add a drop shadow to the zoomed callout and it was perfectly synchronized to my master video. A little fade in/fade out animation completed the polished effect.
Hope this helps.

I know editing features in avfoundation for merging videos, trimming video and run time video effects through glview and post process using avexport session. I made one video editing app also with lot of cool features - Video Movie Editor- A Music Maker For Insta.gram by Dynamite Standard, LLC
https://appsto.re/gb/hSe4_.i
But now we want to go ahead like VivaVideo app with cool transitions in video with effects

I tried with avcustomcompositor class to filter or process each frame using core image but it's not working smoothly and crashes even in iPhone 6s with blur + mask effects.
I don't know about opengl but i am ready to learn it, but specific to video editing , so viva video app uses opengl to render and giving effects to video??
One of my friend said that they are using .xp file like json and they got all transformation values from it for each theme.
So anybody will guide me how to achieve that kind of effects? In google i only see in suggestion of GPUImage and that libray is great but not fitting with my requirements.
In past i asked question like show video with it's aspect frame And show blur frame of that video in background but i didn't receive any answer of it. That's the first basic step to start this.

I want to create a game kite flying . Now suppose we have two button's Up and down. When we press on button up kite go away from screen and it should look realistic small while its going away and away on continues press . If we press on down it should come down in same way and it look bigger .
How can show kite depth on screen with sprite kit or any other framework ?
Thanks
Rajender
You could try adjusting the Scale property of the SKNode when a user presses the up button. You'll have to detect the specific key type that you're looking for, but you could do something like:
- (void)handlePressDown:(UIGestureRecognizer)recognizer
{
// ....Detect specific keystroke
_kiteScaleAmount++;
[kite setScale:_kiteScaleAmount];
}
More info on SKNode here.
Since you included the [scenekit] tag in your question, perhaps you're also looking for 3D solutions?
You can use SK3DNode to add 3D content—an embedded SceneKit scene—to your otherwise 2D SpriteKit game. So, if you have a 3D model of a kite, you can build a SceneKit scene around that, then attach it to an SK3DNode in your game. Then, to make the kite get farther and nearer to the viewer, adjust the camera in the SceneKit scene.

I want to draw a words grid that user can select the wrods, like the image below
I think the best way is to use a UICollectionView element for draw a grid but how can I handle touch events and mark selected letters?
There is no one answer to your question. You could use individual UIButtons for each letter or set up your own touch coordinate tracking system corresponding to letters or do something completely different. It boils down to what you feel comfortable working with and your experience level. To get the ball rolling, I would suggest you take a look at this Ray Wenderlich tutorial which shows how to create a letter word game by dragging letter tiles. The tech in this tutorial will definitely help you with your project.
Updated:
If you go the button route, you can create them programmatically and pretty much do anything you want. Change their title (in your case) letter, show or hide them, track various kind of touches, and so on. For the letters and tracking touches, there are probably a number of methods of doing this. Try putting your letters on a subview while keeping track of their center coordinates. Then add a new subview over your letters to track the user's touches.
You will have to read and understand the UIGestureRecognizer Class.
Here is an example of how to get a user's screen coordinates from a touch.

So, my background is in the color #DBDBDB. I need an animated loading image like this one for my site's background. Unfortunately since GIFs don't support partial transparency, I'm left with a white outline in my background. I've tried to take this image and edit it to use the same background color to no avail. Then I tried to make a loading animation of my own but that came out horrible. So I do not know what to do. Can anyone help me? I would like to use this image but instead of a white outline, I would like an outline in the color #DBDBDB or a background #DBDBDB
Or to be told how to do this in CS5.5
You can use the wonderful little service AjaxLoad to generate a loading animation for any combination of colors. Just pick #DBDBDB as the background color and use "Indicator Big" as your style.
Here's your image:

I have an iphone app with a picture of a face in the uiimage. I want to only change the eye color on the face by tapping on a button or tapping on a color wheel. Can you give me some help in what code I would need.
I would suggest taking a look at OpenCV. It works quite well on iOS devices, the main code comes with examples on how to build iOS applications and there is a lot of material on how to do eye detection and from there you should be able to change the colors.
Keep in mind this is not a simple task and you could accomplish with a easier thing. But you could learn a lot and there are tons of good resources around this topics.
If you want to do something faster, you might be able to just detect the touch on the UIView(enable user interaction) and present a color picker, after the color has been presented you could create a simple view on top of the image that has a circle with the color that was selected. It would be crappy, but might be a good idea to do a simple simple prototype.
