Unblocking The Main Thread Solving ANRs and Frozen Frames
Vicky stacey question four answer
1. Photoshop is an incredibly powerful programme, and we used a lot of features such as,
changing the opacity of images, changing the saturation, and turning them upside-down.
The below programs are other technologies which I used in research, filming and the editing
process of making our products.
1. Research
Google chrome and maps
The internet is an amazing invention that allows you to access an unimaginable amount of
information with the flick of a button. There are different servers and platforms that allow
you to reach the same information, but in varying ways. For example, you can use Safari on
Apple products, or download Google Chrome.
To begin using Google Chrome, either directly open the server, or open the internet
normally and search into google. Once the google screen is open, search a key phrase or
question and click on the search button; or press enter. The results for your findings are
displayed below, and to view the websites Google found for you, click on the hyperlinks and
you will be directed to that page. To get back to your search results from this page, press
the 'back' button (or the back space). To edit your search, click on the search bar and simply
type in any changes and search again- Easy!
You can also find photographic results for your search. This can be achieved by searching as
normal, and then clicking on the 'images' tab which will re-direct you to all of the images
found. You can save the images by clicking on them and then 'right hand clicking' (ctrl and
click for Apple products) and selecting the 'save' option.
Google maps is just as straight forward. Find your way to the Google homepage, and search
your desired destination or post code. Then proceed to click on the 'maps' tab and a large
picture of the destination's location is displayed towards the right side of the screen. You
can then go on to finding directions by clicking 'Get directions' to the left of the screen and
following the instructions.
Screen Grabbing
On most computers, you can 'screen grab' or 'print screen' which enables you to initially
take a photo of everything you can see on the computer screen. To do this, you simply tap in
a key board shortcut (most computers 'ctrl alt del' and on Apple 'ctrl shift 4').
As I am using an Apple product, I will explain how to use this key board short cut.
Once you have used the shortcut, the cursor will change into a small cross. Using this tool,
you can select an area in which you want to copy. You do this my holding down the curser
and dragging over the area you want to select.
Still camera
2. A standard camera used to take still photographs is very easily mastered. Find the power
button, and press it firmly once until the lens begins to open outwards. The camera will
open up onto a screen where it is ready to take a photograph. You can proceed to take a
photo by pressing the capture button. You can look through your photos by pressing the
gallery button (frequently looks like a play button) and using the left and right navigator to
view them all. Many cameras have a zoom function, which allows your to gain a close view
and do 'close up's '. You can download your images to a computer via a USB cable and
following the directions on the screen.
2. Filming
Camera and Tripod
Another kind of camera is a video camera, which specializes in moving images.
In the same way as a stills camera, all you have to do is turn the camera on, and press the
'record' button to begin filming. To stop filming, press the record button again. You can
watch your footage by looking at the gallery, and again can download the data on to a
computer via a USB chord.
You can use a tripod to steady your shots and make them better to watch. The tripod has
three legs that you pull out by unhooking latches and re-hooking them once the legs are
fully extended. Attach the camera to the tripod by screwing a detachable piece of the tripod
on to the base of the camera and then fix it back onto the tripod.
Premier pro
Premiere pro is an advanced programme which allows you to edit footage and other
medium and achieve a professional look.
You can add credits in my selecting a clip and clicking on the fonts tool (looks like an A) and
typing what you want on screen. You can easily edit this text by changing the font, text size,
colour, and positioning on the screen. Once you're happy with the text, close the window
and return to the original premier pro screen. To edit this text later on, just double click on
the desired clip and the text window will open up again.
You can easily fade between two clips by putting them next to each other on the work
space, and selecting the 'pen tool' on the left of the work space (the pen tool looks like an
old fashioned fountain pen). The tool will then enable you to lower the light levels on the
clip and therefore fades to blackness, and then you can place the next clip on the line above
and fade the clip upwards from darkness, therefore, giving the effect of the clips fading into
each other.
Blurring can ask be achieved by clicking on a clip, and selecting the effect you want in the
video effects. You can blur the clip from a certain part by double clicking the clip, and going
on the next tab on the preview area. You can then use percentages to alter the amount of
blurriness (or other effect you've chosen) at different points in the clip.
3. You can effete the speed of a clip as well. Simply, select the clip you want to work with and
select the tab along the top of the screen called 'clip's and select the option called
'speed/duration'. A small window will appear and you can then edit the speed of the clip by
altering the percentage in a box
