Glossery of terms
Video Formats
It is a form in which the computer can store a video file
in. To decrease the size of a file, the video can often be compressed. For
example, .mov is a video format created by Apple in order to play their
multimedia content- it can also be viewed on Windows computers using Apple's
program call QuickTime. Likewise, the file extension .avi was created by
Microsoft which enables WIndows to play multimedia files.
Streaming
Streaming lets the presenting of a file in real-time without
having the user download it. The application receiving the data must be able to
amass the data the streamer is sending quickly enough in order for the data to
appear smoothly. If it is received quicker than needed, then that excess data
will be saved to the buffer - this will prevent lag by loading when the
transmission slows or stops. YouTube would be an example as you are viewing a
multimedia file. Spotify would be an example too, as audio is being transmitted
to your device. Gamers often stream on a platform called Twitch and hitbox which
is a streaming media service. They are able to broadcast themselves playing to
a big audience through these platforms.
File Compression
File compression is when a file is made smaller than its
original size in order to allow quicker and easier file transmission, as well
as the primary purpose of taking up less space on a disk. For example, some
files can be zipped (this can be done to one, or multiple files). This zipped
file will be of lesser size than the original files that are being zipped up.
However, to use them, they would need to be 'unzipped'. Programs such as WinZip
allow you to do this. Also some programs like handbrake compress the video
files so it takes up less memory.
Aspect Ratios: 4:3, 16:9
Aspect ratio describes the relationship between the height
and width of an image/video/frame in proportion to one another. For example, in
aspect ratio 16:9, the width is almost double the height. In 4:3, the height
and width are almost the same. The 16:9 ration is often used for movies as
consumers like bigger, greater screens. The aspect ratio 4:3 was used however,
to make older movies and makes the film more square with black bars on the
side.
Frame Rates
A moving image is made up of many still images. The frame
rate is the frequency these frames appear at. It is measured in FPS (Frames per
Second) so the lower the frames the lower the quality of the video and becomes
more choppy after 24 fps, after 60fps it becomes more life like and higher
quality.
Evaluation
Evaluating
my final video; there are certain things that I think I could do better and
that I could improve on; for example, not to leave editing my video so last minute.
What I thought
was good:
I made
various introductions to my video profile showing off different editing styles
and also structuring my video. I personally liked the colour correction as it
levelled out the various colours and made it look more professional. I also
like my music choice as it gives out chill vibes and has no speech so the
audience focuses more on my voice. I used a variety of shots and angles making
the video look more interesting ranging from long shots to extreme close-ups. In
the editing I also synced the transitions with the music to make the edit flow
better and look more aesthetically pleasing.
What I thought
needs improving:
However, my
audio was a bit too heavy on reverb as I did not know the settings too well as
its my first time using it; I used reverb as the original audio quality was
quite bad and it had a lot of background noise in it.
Also some
of the shots that I took were not Stable-I could have used a tripod to make it
more stable. Some of the shots were badly lit and noise detected on the dark
parts of the video.
One thing I
would like to change in my filming is the interview as I did not check the
footage until after I recorded; the recording was data glitched and showed a
lot of tear in the video and ruined the quality of me and also the green screen,
that’s why u can see a green glow around me on the interview part of my video;
This also leads to another thing I would not do in future projects, that is to
not leave things so last minute and rush everything as it ruins the whole
quality of my work. I know I can do better but I rushed it and edited
everything in one day; If I had more time the video would be up to standards
and higher quality in structure and better transitions.
I changed
some things from my script and shot list and improvised as I didn’t like what
it looked like on screen.
Conclusion:
Overall I still
like the outcome of my video as everything pretty much flows together but In future
I should give me self more time and not rush things last minute as I know I can
come out with a better quality video. Also I would want to get a camera and
record things myself and not rely on other people as it did not give me the
freedom of where to go and shoot.
