Video editing refers to the editing process of first recording the expected image with a camera, and then using the video editing software to make the image into a disc on the computer. At present, there are many video editing software such as VideoStudio.
 
basic concept
You may have seen some TV commercials and articles in magazines that tell you: "A new era of personal video has arrived." In this era, anyone can sit in front of a home computer and produce a studio with a quality comparable to that of a studio Comparable videos.
All you need is a video camera, appropriate software, and the desire to create. With today's cameras and computer technology, you can:
Create an excellent work that reproduces your summer vacation experience, so that those "family movies" are beyond your reach.
Create a demo video with extraordinary effect, blockbuster.
Create a complete documentary and use it to reflect any theme or question you wish to present to others.
Create a popular movie of your own and enjoy millions of dollars at the box office, just like the movie "The Blair Witch Project".
 
 
Anyway, this is indeed a good idea. However, if you have ever tried to sit down and practice for yourself, you will know that things are not as simple as they seem. In fact, its complexity is increasing day by day, so that users hardly know where to start.
 
Glossary
AVI
Acronym for Audio-Video Interleave (Audio Video Interleave), a digital video file format specifically designed for the Microsoft Windows environment.
BD
Blu-ray discs are an optional disc format that uses blue-violet lasers, allowing data to be packaged in 25 and 50 GB Blu-ray discs and capable of playing high-definition video.
DNLE
Acronym for Digital Non-Linear Editing, which is a method for combining and editing multiple video materials to produce the final product. DNLE provides random access to all source materials and all parts on the main tape at any time during the editing process.
DV
Acronym for Digital Video, which represents a very specific video format, just like VHS or High-8.
DVD
Digital versatile discs (DVDs) are widely used in video production due to their quality advantages. It not only guarantees first-class audio and video quality, but also saves many times more data than VCD and SVCD. DVD uses the MPEG-2 format, which has a much larger file size than MPEG-1, and can also be manufactured in single-sided or double-sided and single-layer or double-layer formats. These DVDs can be played on a separate DVD player or on the computer's DVD-ROM drive.
FireWire
A standard interface for connecting digital audio / video equipment such as DV cameras to a computer. It is a trademark name taken by Apple Computers for the IEEE-1394 standard.
HDV
Abbreviation for High Definition Video. This is a video recording format, through which high data compression can be obtained, and thus higher picture resolution. The resolution of HDV can be up to 1920 x 1080.
IEEE
Abbreviation of Institute of Electrical and Electronics Engineers (American Institute of Electrical and Electronics Engineers), a non-profit organization responsible for setting and reviewing standards in the electronics industry.
IEEE-1394
A standard that allows a high-speed serial connection between a computer and a DV camera, VCR, or any type of digital audio / video equipment. Devices that meet this standard can transmit at least 100 megabits of digital data per second.
MP3
Acronym for MPEG Audio Layer-3. MP3 is an audio compression technology that can produce audio quality close to CDs with a very small file size, allowing it to be quickly transmitted over the Internet.
MPEG-1
An audio and video compression standard used in multiple products such as VCD. For NTSC, the video resolution is 352x240 pixels and the frame rate is 29.97 fps. For PAL, the video resolution is 352x288 pixels and the frame rate is 25 fps.
MPEG-2
A subset of MPEG-1. It is an audio and video compression standard used for products such as DVDs. For NTSC DVD, the video resolution is 720x480 pixels and the frame rate is 29.97 fps. For PAL DVD, the video resolution is 720x576 pixels and the frame rate is 25 fps.
NLE
Abbreviation for Non Linear Editing. Traditional editing of VCRs must be linear, because the material on the video tape must be accessed sequentially. Computer editing can be done in any convenient order.
NTSC / PAL
NTSC is the video standard used in North America, Japan, Taiwan, and some other regions. The frame rate is 29.97 fps. PAL is commonly used in Europe, Australia, New Zealand, India, Thailand, and some other Asian regions, and its frame rate is 25 fps. There are other differences between these two standards. In the field of DV and DVD, the video resolution of NTSC is 720x480 pixels, while PAL is 720x576 pixels.
SVCD
Super Video CD (SVCD) is usually described as an enhanced version of VCD. It is based on MPEG-2 technology that supports variable bit rate (VBR). The typical playback time of SVCD is about 30-45 minutes. Although you can extend the playback time to 70 minutes, this requires lowering the sound and image quality. SVCD can be played on a single VCD / SVCD player, most DVD players, and all CD-ROM / DVD-ROM with DVD / SVCD player software.
VCD
Video CD (VCD) is a special version of CD-ROM that uses MPEG-1 format. The quality of the exported movie is almost the same, but it is usually better than that of the movie using VHS tape. VCDs can be played back in CD-ROM drives, VCD players, and even in DVD players.
Split by scene
This function automatically divides different scenes into several separate files. In Corel VideoStudio, the way the scene is detected depends on the steps you are in. In "Capture Step", the "Split by Scene" function detects each scene based on the recording date and time of the original shot. In the "Editing Steps", if the "Split by Scene" function has been applied to DV AVI files, you can detect scenes in two ways: by recording date and time, or by changes in video content. But in MPEG files, scenes can only be detected based on changes in content.
