Editing Video

Capture Process (Capture)

The arrest (capture) is the storage of the input signal (video and audio) into a movie file format (AVI, MPEG, etc.) into a computer for storage purposes to a video file format used hardware that popular with the name Capture Card. There are two types of capture cards based on the support facilities (for editing video), the household class and professional class. For the class households editing facilities are limited compared to professional classes, so the consequences of the price too far adrift. Examples of this type of device is snazii Video Creator, pinnacle studio DC10

Plus, etc.. For the professional class is equipped with real time video processing in hardware so that the process is more cpat and produced better quality. Examples of this type of device is Rt2500 Matrox, Pinnacle Pro One RTDV etc.. Software used was accompanied at time of purchase. Example programs are included on the card is around editing adobe premiere professional types.

Video signal capture process includes two types of input signals are used, namely:

a) The analog signal

To change the output sinyak video cameras, camcorders or cassete Video Recorder (VCR) analog type, used tools that capture card. This tool serves convert analog video into a video or movie file format (AVI, MPEG-1. MPEG-2, etc.)

b) The digital signal

To process the output signal video camera / camcorders digital type, the mainboard is equipped with several types of IEEE 1394 connector. On a computer that does not have this facility can be added to digital capture card types that have an IEEE 1394 connector. An example is the Dazzle DV Editor SE.

On the capture of household type is generally only used to capture analog signals, while the professional grade video editing tools in general have both types of analog or digital inputs.

2) Video Processing (editing, adding animation,

dubbing)

Video or movie files (AVI, MPEG, etc.) can be prepared or carried out the editing process (editing).

Editing of video files including:

a) Cutting (cutting)

Movie files can be cut as needed. Moreover, it can be separated (split) between video and audio to the captured video or audio only.

b) The addition of the effect (effect).

Encoding the movie file can be given effect which include; effects of transition (transition effect), the effect of motion (motion), mauoun video filter (coloring, camera effects, lighting, painting, focus, etc.). Moreover, it can be done by giving the effect of laying (overlay) a few videos to other videos by way of chroma key, even given additional makeup effects.

c) The addition of a sentence (Tilling)

To provide a description of the video aired the addition sentence (Tilling) The sentence may be the effect of motion or animation.

d) The addition of animation (animation)

The addition of animation or graphic images (still image) and the text will provide a more vivid impression. There is a good animation program two-dimensional (2D) and three-dimensional (3D).

e) the audio settings (volume, sound effects)

Audio or video sound file can be set on the volume, plus the effects of (audio filter) and mixed with other sound sources.

f) Replacement of voice or voice-over (dubbing)

The voice on the video file can also be removed or replaced with other sounds through the process of sound recording using a computer program. It can also be added as an accompaniment of music (sound track).

For this purpose use a video editor program, among others; Ulead Media Studio, Ulead Video Studio, Adobe Premiere, Pinacle Studio, MGI Video Wave, Vegas Video, etc.. After processing, the file can be obtained through the process of rendering the resulting mixture. File formats include AVI, MPEG (VCD format), etc..

Supporting programs such as video editor is a graphics processing program (eg Adobe Photoshop, Ulead Photo Impact), animation maker program (examples:

3D Studio Max, Ulead Cool 3D), recorder and voice processing program (eg, Sonic Foundry Sound Forge, Musicmatch Jukebox).

3) Movie File compression (encoding).

Mixed results file editing program (the rendering) can be played back (playback) with a computer program, but can not be directly played on other devices such as VCD player. The file size is very large so it does not fit on a CD (CDR). So that the storage media (CDR) is able to accommodate movie file with a longer duration, then the file should be uncompressed or compressed according to the standard playback devices are used (example: VCD-PAL). Through the conversion or compression of movie files (AVI, MPEG, etc.) to another format is called encoding. Examples of program encoding VCD (MPEG-1), among others; Panasonic encoder, TMPGEnc, Xing MPEG encoder, LSX, etc..

For the purposes of making an interactive CD, in general, the format used is Quicktime Movie (MOV), by the process therefore must use a file compression format.

4) Chips VCD burning (burning)

How to save files on a CD (CDR) is through the burning of a laser beam on the surface of the bottom. CD burning program (CD Burning), among others, Ahead Nero Burning ROM, Roxio CD Creator, Ulead DVD Movie Factory, etc.. After the combustion process, then the CD (CDR) which has the format of VCD can be played on VCD player.

5) Preparation of Cover

Display the cover (cover) VCD has a role and its own charm. VCD packaging so that products seen

better, then the cover should be well designed, on the front side and on keeping his CD. To support this purpose may use the graphics processing program such as Corel Draw, Adobe Photoshop, Ulead Photo Impact. In addition there are special programs that cover maker is usually packaged with a CD-burning program such as Ahead Nero Cover Design.

In the process of editing (editing) needs to know the video format that will be generated. By knowing the video format to be used, then the design of a graphic or still images or create animations (both

2D or 3D) may correspond to the ratio of the size of the frame (frame size) and number of frames per second of video format that is generated.

From the description above indicates that the computer

very important in the production process VCD. Good or bad impressions VCD influenced by the application program used and the capabilities of the hardware used. The use of computer programs in the VCD production process many kinds. In this paper only shown a few examples of programs used to support the production of easy-VCD

obtained in the market. Knowledge of video processing techniques (editing) is indispensable in making media Video / VCD. By knowing the video processing techniques, will open to the makers thought the concept of the script and production team that will work in the field in shooting (video).
