Using an analogue video
camera
Analogue video has to be digitized before it can be edited on a
computer whereas digital video can be transferred directly into
the computer often using a firewire card. To capture digital video
from a standard analogue video camera without a digital-out capability
you will need to buy an analogue video capture card for your computer
and these can be very expensive. To capture digital video you might
need to buy a firewire adapter but these are very cheap and often
come installed as standard.
Digital video equipment offers
a higher quality both for video and audio than analogue video and
can be transferred to the computer more quickly - it is better to
use digital video as a starting point for further work..
Using a digital video
camera
You can capture video from a range of different sources.
The best quality method of capturing video to your computer is to
use a digital video camcorder via a ‘Firewire’ (IEEE
1394) cable. Video can be transferred via USB but Firewire is a
far faster transfer technology and is the standard on many cameras
and also on many modern laptops. Firewire connectors come with 4
pin or 6 pin plugs - usually the 6 pin connects to the computer
or laptop and the 4 pin end connects to the camera - you should
check the size of the sockets before committing to buying a cable
"Digital Video
in" capability
By default all digital video cameras are capable of outputting digital
video. However, digital video cameras which can except a digital
input are classed as video recorders and subject to additional EU
tax making them slightly more expensive. Often "Digital Video
in" enabled cameras have an “i” at the end of the
model number to indicate that they are "DV in" capable.
The advantage of "DV in"
capability is twofold:
- You can put your edited
video from the computer back into the digital video camera tape
and therefore run copies off onto VHS tapes for distribution.
- You can record VHS analogue
tapes into your "Digital Video In " enabled camera,
and then transfer the video into your computer for editing.
Resolution and file
size
When capturing digital video the defaults picture size is usually
720X576 pixels which is the size needed to fill the screen of a
TV when played back after editing. The down-side of this that it
creates huge file sizes.
When saving in Movie Maker
if you ‘Save to Web’ the size is 150x 119 pixels and
the drop in quality is huge. However if you want to put your videos
on the web and allow people to download or stream them then you
do have to consider the file size before the issue of quality.
Sound files
In addition to the sounds captured with the video image Microsoft
Movie Maker allows you to lay down one additional track of sound
(this is the biggest draw back of Movie Maker). Sounds - in particular
background music can be taken from many sources.
- You can narrate straight
into Movie Maker if you have a microphone.
- You can turn music from
CD’s to WAV’s or MP3’s from a CD using a CD
ripper program such as Windows Media Player.
- If the final destination
of your video is a computer then MP3 is probably the best format.
If you intend to output your video as a DVD then the extra quality
of a WAV file may be needed. (A WAV file roughly 10 times the
file size of the same audio in MP3 format).
Adding extra sounds
in Microsoft Movie Maker
If you wish to add more soundtracks then you have to do what is
called "bouncing down". This means creating
your film with a narration on it then opening the resulting file up again in a new Movie Maker
project. You will then have gained a spare audio track to put the
music on because your narration will be included in the original
movie. Alternatively use a more powerful video editor, or an audio
editing software programme that allows you to mix multiple tracks,
then to add that to your finished video.
Video formats
The most common types are
- WMV Windows Media Video
– compressed video viewable in Windows Media Player
- AVI An uncompressed video
format – large files! (a Microsoft standard)
- Mpeg 1 The standard to use
if you want to produce video CD’s (VCDs)
- Mpeg2 The standard to use
if you want to produce DVDs
- RealVideo These files require
Real Player to view these but uses good compression techniques
so that videos can be shown over the Internet
- Quicktime (.mov) Another
file type with good compression for streaming video over the Internet
(an Apple standard). Requires Quicktime Player to view these files
Microsoft Media Player only
produces videos in the Windows Media Video format
Titles
Though you can create titles in Microsoft Movie Maker you may want
to produce your own titles in JPG file format in an image editor
such as Adobe Photoshop or Macromedia Fireworks..
You will have to consider the
size of the picture for your title. If you work on a canvas size
of 720x 576 then it will be the right size to go directly into Movie
maker and most other video editors.
If you make it larger than this then Movie Maker and most other
video editors will resize it to fit and there should be no problem.
If you make your title smaller than a canvas size of 720x 576 then
Movie Maker and most other video editors will resize the image upwards
and the title will become pixellated. Remember your titles should
be on a ratio of roughly 4:3 otherwise they would also become stretched
and distorted.
