Moving Image Files
Question 1: What is meant by S.D. (standard definition)?
S.D. (Standard definition) is type of resolution that is usually at 720x480 pixels.
Question 2: What is meant by H.D. (high definition)?
H.D. (high definition) is a higher type of resolution compared to S,D, (standard definition) and is usually set at 1920x1080 pixels.
Question 3: What is meant by 4k?
4k refers to a horizontal resolution on the order of 4,000 pixels and vertical resolution on the order of 2,000 pixels
4k limitations
File size: When you are using 4k for example recording video, the file size can get a bit too big. This is because roughly one hour of 4k recording is equal to 318 G.B.
Filming tech: Recording in 4k is one of the best resolutions you can record in (at this point on time) but some of the equipment that you need to record is really expensive, for example a really good 4k video camera can cost £3,000 or more.
Editing software: 4k video editing can be a bit tricky if you don't know what you are doing. And some basic video editing programs can have trouble rendering and finalizing the edit of the video due to the file size. But on the other side you may need a pretty good computer, and some of the higher quality editing software can cost up to £700.
Exhibition/display tech: When it comes to 4k displays they can be a bit expensive and can cost up to £20,000. But as with (almost) all tech, the price goes down when it gets older and some 4k displays can be as low as £200 (which is still kind of pricey if you have a low income).
Question 4: File types
.MP4: .MP4 is a multimedia container format designed to store audiovisual data.
S.D. (Standard definition) is type of resolution that is usually at 720x480 pixels.
Question 2: What is meant by H.D. (high definition)?
H.D. (high definition) is a higher type of resolution compared to S,D, (standard definition) and is usually set at 1920x1080 pixels.

Question 4: File types
.MP4: .MP4 is a multimedia container format designed to store audiovisual data.
Pro: Suitable for video streaming over the internet, less loss of quality with higher degree of compression and can store data types other than video and audio, such as object descriptors, scene descriptors and other object oriented file structures and MPEG features.
Con: The only disadvantage of .MP4 file format is from editing and movie making point of view. M.P.4 files are not easy to edit or update.
.MOV: .mov is a file extension used by the QuickTime-wrapped files.
Pros: .MOV is a convenient file format because it can hold different media elements, including video and audio, all in one compact place.
If you plan to transmit your file over the Internet, .MOV might be for you because it is used primarily on the web.
Cons: .MOV files work specifically on QuickTime Media Player. If
the computer or mobile device you are using does not have this specific
platform, you have to convert the file to a different format.
Since .MOV compresses files to more compact sizes, the overall quality of the end product might be lowered in the process.
.AVI
.AVI (Audio Video Interleaved) is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows software. .AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback.
Pro: .AVI file format has exceptionally high quality audio fidelity.
.AVI file format is developed by windows, which makes it playable with all the major Microsoft and non-Microsoft operating systems.
Con: AVI files if compressed beyond certain limits result in the loss of video quality. .AVI files if uncompressed can be very large in size as compared to the other file formats.
.FLV
.FLV (Flash Video) is a container file format used to deliver digital video content (e.g., TV shows, movies, etc.) over the Internet using Adobe Flash Player version 6 and newer.
Pro: The Flash player is installed on a higher percentage of end user computers than any other video format.
Con: Flash video does not have the same depth of history as the other major formats and in the last few years. Between versions 5 and 8, Flash video went through two major changes which required a lot of upgrade work for producers.
Question 5: Applications for exporting
Handycam: Most handycams generate .mts file, which is a is a file extension for an AVCHD (Advanced Video Coding High Definition) video clip format for high-definition video.
D.S.L.R: A d.s.l.r camera can generate a .raw file which contains minimally processed data from the image sensor of either a digital camera, image scanner, or motion picture film scanner. But we used a .mov file type instead.
premiere pro: We used premiere pro to edit .mov video files which we captured with a d.s.l.r camera and the proceeded to export to a .mp4 file type.
Windows movie maker: We firstly converted a .mts file to a .avi file and then imported to movie maker. Then edited it and exported a .avi file.
Comparison: Windows movie maker & Adobe premier pro.
Windows movie maker is more simplistic compared to Adobe premier pro; It has less tools and fetchers. Also Adobe is more professional in comparison to Windows movie maker, but is a bit more complicated than it.
