The numbers 16:9 refer to the aspect ratio in relation to the width and height of a video. 16 is the width and 9 is the height.
2. What is the frame-size of a 1080p video file?
1920 x 1080
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 a video file which is 720:50p is 50 frames per second. The p stands for progressive.
The frame rate of a video file which is 720:50p is 50 frames per second. The p stands for progressive.
4. What is the difference between p + i?
The p and i designation is about how frames are shown. The p stands for progressive, and shows every frame continuously. The i stands for interlaced and show half the frame at any one time and 'interlaces' the half frames together so we see a unified movement. The p is better, however produces much larger files.

5. What frame rate is a real film shot at?
The frame rate in which a real film is shot at is 24 (23.976)
The frame rate in which a real film is shot at is 24 (23.976)
6. What might be the advantage of shooting at a higher frame rate?
Shooting at a higher frame rate should increase the smoothness of the action within the film clip.
Shooting at a higher frame rate should increase the smoothness of the action within the film clip.
7. What defines a 'lossy' file?
This is a file that throws away certain bits of information as a result of the file type deciding which parts of the film are most necessary for human perception.

8. Name three file types commonly used in video editing.
Mov. Wav. MP4.

9. What is the difference between a video file type and a codec?
The file type is the container in which the information is stored, and the codec is how the video/audio is compressed to get it fitted into the file, and then decompressed for it to be audible again.

10. What is a bitrate?
A bitrate is the rate at which the file processes information. The higher the bitrate requires a more powerful computer. The higher the bitrate, the better the quality of video/audio.
