The technical side of editing
1. What do the number 16:9 refer to?
This is an aspect ratio and represents the width in the relation to the height of the frame. older style televisions would have a ration of around 4:3, and a newer flat screen HDTV televisions would be 16:9. The width for a cinema screen would be much wider.
2. What is the frame size for a 1080p file?
1920 pixels (width) 1080p pixels (vertical)
3. If you have a video file which is 720:50p what is the frame rate and what does the p stand for?
&
4. What is the difference between p and I (e.g., 1080p)?
The first of these numbers (720) is the video size, the second number is the the frame rate and how many frames there are every second (FPS).
'P' stands for progressive scan, this will show you every frame one after the other. An Interlaced scan will show half the frame at one time, and interlaces these half frames together so we can see unified movement. 'P' is seen as being much better but produces much larger files.
5. What frame rate is real film shot at?
Real film is shot at 24fps and some cameras will offer the option to shoot at this frame rate, although higher will give you smoother action.
6. What might be the advantage of shooting at a higher frame rate?
Having a higher frame rate will give you a much smoother action. But having a higher frame rate will make things more complicated.
7. What defines a lossy file?
Highly compressed file types are called ‘lossy’, whereas less compressed file types are called ‘lossless’. Professional setups use lossless or uncompressed file types.
8. Name three file types commonly used in video editing.
AVCHD, is a domestic camcorder file type. It often has the suffix .mts It is highly compressed.
MOV,is a video file type associated with Apple Quicktime. It has the suffix .mov. It is also compressed.
FLV, and F4V are Flash video files.
9. What is the difference between a video file type and a codec?
A codec is used to create the video file, which can be many different types. A file type is the way the video is contained after being compressed via codec.
10. what is bitrate
The bitrate is how much information is used in the video per second. The higher the bitrate yhe higher the overall quality.
