Technical Aspects of Editing

1. What do the numbers 16:9 refer to?
16:9 is mostly used for wider-screen TVs and refers to the aspect ratio where 16 is the length/width and 9 is the height.

2. What is the frame size of a 1080p video file?
The frame size of a 1080 pixel video file is 1920 X 1080

3. If you have a video file which is 720:50p what is the frame rate and what does the p stand for?
The frame rate of 720:50p is 50 frames per second. The p in this video file stands for progressive.

4. What is the difference between p and i?
The difference between p and i is that p stands of progressive which shows every frame from one to another. However, I stands for interlace which only shows half of the frame at any one moment so that we see unified movement from the half frames.

5. What frame rate is real film shot at?
The frame rate which real film is shot at is at 24/23.976.

6. What might be the advantage of shooting at a higher frame rate?
The advantage of shooting at a higher frame rate is due to it being best for shooting slow motion footage which also allows fast movement to be shown without it becoming a blur.

7. What defines a lossy file?
A lossy file allows the file type to decide which parts of the film are most necessary for human perceptions, due to this file type throwing away certain bits of information.

8. Name three file types commonly used in video editing.
Three common file types used in video editing is WAV, MOV and JPEG

9. What is the difference between a video file type and a codec?
A video file type is the container, however a codec is how the video and audio is compressed which allows it to get inside and then decompresses to read the codec. This is also called decoding. 

10. What is bitrate?
Bitrate is the rate at which a file processes information.
